Btw, I would build the basement.

| I have worked with two friends that dug basements and placed foundations
under existing houses. It is EXTREMELY labor intensive. It means basically
digging with a shovel, first some holes in which to build temporary cribs
to support the house, then digging the entire foundation by hand. The only
reason I'd ever attempt it would be the case of a collapsing foundation,
and then only if the house was worth saving. It would actually be eaiser
to move the house back off the foundation, build a basement and move the
house back!
Id look at building up, or building a new wing, with basement under it, but
leave the old crawl space as is.

| My husband and I put a basement under out house from a crawl space
19 years ago. I seriously doubt if I would want to tackle that
again. However, entering a cellar at any time beats crawling under
the house.
I think if I had to do it again I would seriously consider raising the
house and matching the walls to meet it first.
Have fun, whatever you decide to do.

| re: .0
A very novel idea that I've seen, particularly if you have a small lot,
is to do neither dig, nor add wing. The general reference is the Good
Housekeeping magazine, and the concept is to:
Raise the existing house, and construct a New first floor under it, thereby
conserving land, and keeping existing roof structure intact.
The 'general' range of issues is sometime between Aug 85 and Dec 85.

| What do you want the space for? If it's any sort of living space, I'd
opt for an addition. A basement is a basement is a basement, no matter
what you do to it. Personal bias, but I have NEVER seen any room in a
basement that I'd want to use for living space.

| We just moved into the house we built this last fall. When the foundation was
dug, the floor of the hole was out of level by almost a foot, which meant that
we had to dig out part of the floor, to a maximum depth of about 6". Just that
was a _lot_ of work. Consider that we were digging in an area where we could
stand up, and swing a pickaxe to break up the dirt, and could easily load it
into a wheelbarrow to take it out of the cellar. You are going to be digging
where you can't stand up, and you're probably going to have to take the dirt
out in buckets, unless you can rig up some better way to get it out.
I think, facing your choice, if it would cost twice the money for half the
space by building an addition instead of digging out the crawlspace, I'd opt
for the addition.

I'm in the process of doing both digging out and adding on. I
haven't found the digging all that bad. What I did was knock out
a 5 foot wide whole in one wall of the current 4 foot high foundation
so it was large enough to fit a wheel barrow. From there I under
cut the foundation on that wall in 6 foot sections, let it hang
and dug down the required depth for the new wall. I then poured
that portion of the wall progressing all along that first side.
Now I'm under the house and diging the floor down to provide a 7
ft ceiliong when finished. I'm about half way down the house know.
as I'm going along I continue to under cut six foot sections of
old foundation and pour the new.
The reason I'm digging is two fold. I want the basement for
a work shop, I plan on building a amphibious airplane as I live
on a lake and a walk out basement will provid a perfect work shop,
also we're adding a second floor to our house and due to the
construction of the old foundation it was not capable of supporting
the weight of a second floor.
Digging out a into a basement is not a small task but.....
if you want it bad enough like myself it worth it. By the way
it's taken about 4 months of 4 nights a week 3-4 hrs each to get
half way.

48.10 | Merging new roof into old roof | FRSBEE::PAGLIARULO | | Wed Apr 02 1986 18:25 | 12 |
| I want to enclose a deck this Spring and would like to do the work
myself. To get the interior height that I want it looks like I'm
going to have to attach the porch roof to the house roof rather
than to a joist nailed to the sidewall. Before I decide to do this
myself (the thought of cutting through the house roof is a little
scary) does anyone know where I can find out more about the how to
of doing this successfully? Anyone have experience with it.
Also, what are the rules around minimum roof slope to be able to
use shingles rather than rolled asphalt or other such coverings?
George

48.11 | Then don't cut a hole in the roof | BEING::WEISS | Forty-Two | Thu Apr 03 1986 09:37 | 16 |
| You don't necessarily have to cut through the house roof to attach the new one.
If you can find where the house rafters are, just sit the porch rafters over
them and nail right through the shingles and plywood. Just make sure that you
get the new rafters over the old and not on the plywood in between. If you
can't line the rafters up for some reason, you could nail a joist to the roof
and rest the new rafters on that. The beauty of this method is that you are
never exposed to the weather. If the shingles currently on the roof aren't too
brittle, you ought to be able to weave the new ones underneath and not disturb
more than a row or two of the original shingles. If they are too brittle, you
may have to reshingle up to the ridge.
Most shingle manufacturers suggest a 4:12 pitch to be the minimum, although if
you put tarpaper underneath 3:12 is ok (that's what's on my house). Anything
lower than that I'd go with roll roofing.

| Thanks Paul, I thought of nailing a joist to the roof but was told
that this wasn't the way it should be done. Are there advantages
or disadvantages to either of the 2 methods you suggest? They sure
would make it easier! Anyone else have any experience with this?
I assume that by 3:12 or 4:12 you mean inches drop per horizontal
inches the roof runs. Am I right?
George "If I were a carpenter..............."

48.13 | | AUTHOR::WELLCOME | | Thu May 08 1986 12:55 | 8 |
| "Nail a joist to the roof"? I don't quite follow. Oh well.
I think I'd pull off the soffit boards and slide the new roof rafters
in next to the existing roof rafters, resting them on the top plate
of the wall and nailing them into the sides of the existing roof
rafters, assuming that would give enough slope to the new roof.

48.8 | Sounds strange | NUWAVE::SUNG | Al Sung (Xway Development) | Thu Jun 26 1986 16:40 | 7 |
| The idea in .4 sounds a bit strange. Lifting up the house and
installing a new first floor. Then the living rm, kitchen & dining
room would be on the second floor, not to mention your foyer. Also
you would have to disconnect all of your plumbing and electricity
in order to do this. If you just add another floor by removing
the roof, then all you have to do is add onto your existing utilities
or add new ones (rather than disconnecting/reconnecting & adding).

I'm considering adding a 2nd floor above my bedrooms. The bedrooms are 11'
wide with a 3' hallway. From the outside wall of the bedrooms to the inside
wall of the hallway it's 14'. There are 2' overhangs outside of the bedrooms
and over the porch.
Would it be possible to add a 38' by 18' second floor above the bedrooms.
My plan would be to:
1. remove the old roof/plywood
2. saw off the existing rafters close to where they join the old ceiling
joists
3. Put new 2x8's next to the existing 2x6's for the new 2nd floor
floor joists.
4. Put 3/4 toung and groove plywood down for the flooring for the
2nd floor
5. Build exterior walls
6. Put roof trusses in place
7. Puts new 1/2 plywood down for roof
8. Put new shingles in place.
Questions:
1. How can I tell if the floor joists under the bedrooms are beefy
enough ?
2. How can I tell if the foundation is stong enough ??
3. How can I tell if I have enough load bearing walls ??
4. Can I extend my new floor joists 2' beyond the existing walls ??
5. Any body have any experience doing anything similiar ??
6. Are there any books or magazines that might discuss what I want to do
IS IT A STUPID THING TO CONSIDER ??? :)

| I really don't have any real experience in this area but a friend has done
something similar. I assume that by
3. Put new 2x8's next to the existing 2x6's for the new 2nd floor
floor joists.
you mean that you will remove the flooring/sub-flooring and nail the 2X8's to
the existing 2X6's? As for strength of the floor, I would wonder about the
span. If it's under 12 feet, it sounds reasonable but if more, you might need
to go with something like a 2X10.
As for extending the joists 2 feet, that doesn't sound like much of a problem
assuming the exterior walls are stong enough (which they "usually" are).
Please note that I'm NOT a building, so this is just kind of winging it.
I suppose if I was doing it and was getting concerned about whether or not it
would fall down after it was done, I might call a few contractors in to bid on
it and ask THEM a lot of questions. Hopefully they could answer all yours and
possibly raise a few more you hadn't thought of.
Is it worth it? Sure... You'd have a blast doing it (assuming you're not in
too much of a hurry!).

48.16 | Recent experience | NOVA::PAL | Paul Lemaire | Thu Jul 03 1986 20:52 | 43 |
| If your house is conventionally built, your existing structure (foundation,
walls, etc) is fine. Incidentally, the bedroom floor joists don't figure
into it unless they, too, are cantilevered.
My brother and I are in the process of converting his former ranch house
into a cape. The bull work is done (6 men removed the old roof, raised
rafters, and skinned the new roof in a week-end). We've built 2 of the
4 gabled dormers since and shingled that side.
My brother did a LOT of preparatory work before 'the big week-end':
He took off a gable end and cut back the eaves so we could insert the
new joists and put the sub-floor in ahead of time. He also built the
stairs; a real boon. The rafters were, of course, pre-cut. He used a
technique from Fine Homebuilding: the rafters have no tails but a notch
cut at the bottom which locked into a 2x6 nailed on top of the joists.
He made dummy rafter tails in his shop; these were nailed to 1x strips
and nailed to the house in sets. The roof sheathing ties it all together.
Here's what we did with the floor joists:
metal cross-bridging
__New 2x10 joists |
/ V
___--| |--___ ___--| |--___ ___--| | existing 2x6 joists
- | | ----- | | ----- | | /

| | | | | | | | | | | | /
______[_]______| |______[_]______| |______[_]______| |_________ |- top plate
_______________[_]_______________[_]_______________[_]_____________V_______
__________________________________________________________________________
Benefits:
The 1x6 spacers keep the 2x10 floor joists off of the ceiling: No
risk of cracks; sound insulation (the kids' rooms are going to be
upstairs); space to string wiring under joists.
By not building sister-joists (as you are suggesting) he further
avoided ceiling cracks (by not driving spikes into existing joists.)
Facilitated pre-building the floor since we didn't have to work
near rafters.
Final Note: My brother bought a 30x50 plastic tarp plus a bunch of smaller
ones. With these he managed to keep the house weathertight
between steps. Impossile otherwise.

48.17 | -< Have Done It>- | JUNIOR::CAMBERLAIN | | Tue Jul 22 1986 12:57 | 29 |
| Adding a second floor is a great way to increase living space!
I have help add a second floor on my brothers home and have build
two dormers of my own, so I do now somthing about the problems you
my get into.
Weather can be a real problem because once the roof is offyou will
spend a great deal of time protecting it from rain. Do not overlook
the wind.................
Use 2x10 for the floor and the over hang should not be a problem.
As for the weight on the foundation, I would only be concerned if
it was not a concrete foundation. Field stone etc.........
As for the roof trusses, how will you get them up on the walls?
A crane?
Some contractors will actual use a crane and lift the old roof and
add the new walls under it.
You may want to get some estimates just to get some differt ideas
on how it can be done.
Open for questions anytime.............

48.18 | SUN ROOM ADDITION | KIRK::GOSSELIN | | Mon Sep 15 1986 12:04 | 5 |
| I'm looking to add a sun room to the south side of my house. I have

48.19 | go full foundation | WORDS::BADGER | Can Do! | Mon Sep 15 1986 13:23 | 10 |
| I've put sun rooms onto two of my houses so far. I've used concret
pilings on both.
Putting a full foundation represents about 50% of the cost (if you
have the foundation put in by a contracter) of the addition.
When/if you sell you house, the addition with no foundation
adds no value to the house. Of course it costs you no more in taxes either.
Its harder to heat than a foundation too. We use our room spring-fall.
Next time for me it will be a full foundation.

| We had a sun-room added onto our first house (in NH). It was on
piers, primarily due to the cost difference. When we sold the house
2 years later, the room added about $3500 to the value of the house.
(At least that's how the real estate agent detailed it on the appraisal
sheet). I wouldn't hesistate to do it that way again, although
if the $$ difference wasn't much I'd opt for the full foundation.

48.21 | writelocked4080387 | ISHTAR::MCFARLAND | | Mon Sep 15 1986 17:10 | 15 |
| Ours does not have a foundation since it started out to be a deck.
It ended up with a full ceiling and nine sliding doors. We had
the deck built of pressure treated decking. The room is great and
I would not change it except for the floor where I plan to put wood
flooring and a carpet. This should make it into a 3 season room.
If you plan to add on a sun room that will eventually end up a family
room do it so that you can insulate. If you already have a family
room you won't need another.

48.22 | Addition foundation work - bulkhead replacement | EXODUS::SEGER | this space intentionally left blank | Mon Jan 26 1987 08:48 | 33 |
| As thoughts turn to spring, mine turn to a new project. I'm gonna be
putting up an addition and quite frankly the only part that worries me
is the stuff I won't be doing myself and will have to deal with
contractors for. This should involve the foundation, heating, plumbing
and plasterer. But, since the latter three are probably at least 1/2
year or more away from the project start, I'll worry about them later.
However, back to the foundation...
I'm gonna be crossing my water line (from the well), so the first thing
I need to do is deal with the well line. I think the easiest thing to
do is simply put the pressure tank in the new basement. Anybody have good
recommendations for pump people? I called Middlesex Water and Need
Pump. The first said it could be as much as 1K and the latter said
around $200. I think I had better budget close to $500 to be safe.
Next comes the forms people. I have no idea who's good. And then
there's someone to do the floor. I already have someone to dig the
cellar hole.
Almost forgot... I need to put in a hatchway to get into the cellar
(I have to remove the old one). One forms guy I talked to said the
cheapest way to get the steps is to get them pre-formed. He suggested a
place in Merrimack. Said it would run around $500. Anyone have
experience here? Is preformed the cheapest? I have some already and
although the look ok, the treads are very narrow. Perhaps that's the
only to do it if you don't want to stick off the back of the house by 10
feet!
As I said before, dealing with the contractors worry me the most. I've
got to get involved with something like 5 or 6 people before I can pound
my first nail!

48.23 | I've done it this way | AMULET::YELINEK | | Mon Jan 26 1987 09:26 | 42 |
| Over the years the best stairs situation in a bulkhead/hatchway
type set-up I've seen is the type where a stair bracket is nailed
to each side of the foundation (2 on each side) and 2X's (6's or
8's) are slid into the brackets from the top of the foundation to
the cellar floor. It's CHEAP and the benifit that stands out most
in my mind is that big machines or; picture a fridge for instance;
can be lowered vertically into the cellar once the 2x's (making
up the stairs) are removed.

Those dashes in my picture represent the bracket placement as well
as a cross section of where you slide in the stairs. Soooooo, the
width of your stairs is up to you, just tell the forms contractor
the width and the distance from the main structure you want. It
now should be evident that you'll need a data sheet showing dimensions
of this Stair Bracket, this will tell you the inside distance "X"

I've used them and Dick Crowe. I've also used Need Pump Co, and
the owner let me keep his rotary hammer-drill to use over the
weekend. I thought that was generous since he didn't know me at
all. For your pre-formed bulkhead, get somebody not too far from
where you live to install it. If it's guarenteed not to leak
you wouldn't want them to be too far way when it comes time to bring
them back to fix it.

| A word of caution in regards to digging out a foundation---
MAKE SURE OF WHO YOU HIRE AND MOSTLY MAKE SURE YOU HAVE A CONTRACT
AS TO WHO IS LIABLE IF THE EXISTING FOUNDATION IS STRUCK AND IT
COLLAPSES OR CRACKS.....DON'T MAKE ASSUMPTIONS
When you dig or backfill there is an awful lot of pressure on that
wall,that as it was explained to me a slight hit w/the bucket would
explode the wall.I had my entire foundation dug out a few years
ago (the *ss,that built the house didn't waterproff,so I had 3-4
inches of water throughout my basement till I could do it right).
Anyway,do yourself a favor----put it in writing...

48.26 | It's cheaper to do it right... | PLANET::DIGIORGIO | He who proposes, does | Mon Jan 26 1987 12:39 | 12 |
| ...and speaking of water...
.2 didn't mentioned it, in addition to cost and improved access
for moving large "whatevers" into the basement, one other BIG
advantage in pouring a jog for stairs in the foundation walls is
that you'll eliminate the problem of leaks that typically occur
when precast stairs are mated to the foundation.
Oh, if I had it to do over again...

| I live in Harvard and plan to use Joe Shaw for excavating. I've had him
do work for me in the past and is very honest AND a local resident.
That idea about cellar stairs sounds really nifty. Not only is it VERY
functional, it's gotta be cheaper and better than precast.
Keep those comments coming...
btw - i recently called a plasterer. although he couldn't quote me a
price without seeing prints (can hardly blame the guy), he told me that
round $1.15 to $1.25 might be a ballpark per square foot. That would
include everything from him hanging the blueboard to plastering as well
as materials. If blueboard is 32 square feet, that rounds out to around
$35-$40 per sheet. A recent not said that on This Old House a plaster said
he charged $15 per sheet for just plastering and I've priced blueboard
at around $9 a sheet. That means he would be charging around $11-$16 per
sheet to hang it. That sounds a tad high to me. Any thoughts?

48.30 | More Comments | COGITO::MAY | | Thu Jan 29 1987 19:16 | 22 |
| I like the thought about the "jog" in the foundation, mostly about
the removable stairs, not precast. I would just like to make sure
that jog I built matched the offered widths of steel bulkheads.
As for my feelings on precast and bulkheads... Of which I have one
of both. What do you mean "when they leak"? Was the contractor
responsible for foundation coating? Is this work beyond your planning?
Did you apply foundation coating to your addition? I believe that
if you are looking for a "guarentee" of not leaking, the price would
go up. Why not DIY with foundation coating and rolled roofing/poly
coats (as previously described in foundation crack repair)? I did
mine when I built 12 yrs ago and no leaks from this. As for the
leaking of the bulkhead, apply sometype of sealer (Thompson's comes
to mind) before/during the installation of the bulkhead. This will
prevent your caulking (read GOOD stuff) from drying out. Should
last longer than you.
As for a form contractor, I recommend "fast" Eddie Johnson, from
Westminster. He covers a large area and plans several projects in
the same general location at once. They call him fast for a reason.

48.40 | help with roof and foundation of addition | WORDS::HARVELL | | Thu Feb 05 1987 10:07 | 63 |
| I could use a little help in trying to design and estimate a addition that
I would like to build on my house.
The house is a split level with a walkout basement in the back. I would
like to construct a sun room off of the main level dining room with a storage
room below. The size of both rooms would be 12 x 12. Most of the design
and estimating I can handle I just need some pointers in the roof construction
and the foundation.
I would like to pour a concrete foundation. I know that I need to go down
about four feet and would come up just barely higher then the ground level.
My desire is to do this as inexpensively as I can, but still doing the job
correctly of course. So my questions for the foundation are as follows:
o Can I reasonably pour the footing myself? I ask this because
needs to be done before the the rest of the foundation and I
would like to limit the number of times that I have to have the
cement truck come out.
o What should the dimensions of the footing be? The foundation will
consist of three 12 foot walls.
o I am just looking for a slab type flooring. Can I have the
foundation walls and floor poured at the same time? This
would allow me to have the cement truck come out only once.
o If the previous response is yes how should I set up the molding
for the foundation? What about reinforcing rods and straps to
hold the footers?
o Any suggestions for good books on the subject and rough costs?
Next problem area comes with the roof. I think that my best bet comes with
using a gable type roof coming away from the original roof instead of a
shed type roof, such as you might have with windows on the second story
of a cape. This would allow me to maintain a decent pitch on the roof and
to have cathedral ceilings in the room. The questions for this part follow:
o How do I go about tying into the original roof? Do I need to
remove the shingles in the area that I am going to be working
on?
o How do I construct the roof itself for cathedral ceilings? I
know how construct the standard roof but how do you get away
with removing the lower portion without harming the integrity?
o What about venting the roof, soffets and ridge vents?
o Again any recommendations on good books on the subject?
I plan on doing all of the work my self. I just have this thing about paying
for something that I think I can do myself. At least I haven't gotten myself
in any trouble with finishing off the downstairs including a three quarter
bath and a twenty by twenty five foot family room in a Tudor style.

What do you mean? That's a lot of bags of sacrete. How are you
going to pour it yourself? One thing you can do to save money is
to rent a backhoe, and dig a trench the width of the shovel. Then
you can pour the footings without forms. You should call the builder
inspector to ask what size footings he wants for whatever size walls
you're pouring. If you're pouring 8 inch walls he'll probably want
12 inch footings. But you have to ask him (if you're getting it
inspected).

I've never heard of doing that because the forms people wouldn't
be able to remove their forms if they're cemented in on the inside.
But since you're doing it yourself maybe you can figure out a way.
Why do you want the cement truck to come only once? They charge
by the yard, not by the number of trips.
> o Any suggestions for good books on the subject and rough costs?
$52/yard for concrete and ~18/linear ft for someone to come set
the forms and pour.
BTW, are you putting in a new walkout basement? If so, remember
that your footing has to go down 4 feet below the basement door.

48.43 | You can pour a footer | LOCH::KEVIN | Kevin O'Brien | Thu Feb 05 1987 14:56 | 19 |
| Pouring your own footer is not that big a problem if you have the
time. Rent a cement mixer at the local 'rentall' store and buy
the cement, sand....... and have at it. You can use scrap pieces
of aspenite for the forms. Then you can build a block wall instead
of pouring one. It's cheaper but slower. I see noway to pour a
slab at the same time as the walls. Since the hole has to be 2
feet wider than the wall on both sides (working room), how can you
back fill around the wall before it's done?
If the idea is to keep cement trucks off the lawn, pour the footer
yourself, build a block wall and use a wood floor. Then you only
have to worry about repairing the damage from the excavator.
As for the roof, I usually head for the public library. If you
look at a lot of different books you may get an idea you like better.
Good luck

48.44 | Monolithic Pouring ? | COBRA::DUTHIE | | Thu Feb 05 1987 16:39 | 46 |
| I did a 12X12 area of foundation by pouring the footing and the
floor at the same time (but not the walls). The standard footing
is the same depth as the wall is thick, and twice as wide as the
wall is thick. This would mean an 8" deep by 16" wide footing to
support an 8" thick wall.
The reason to limit the number of times that the cement truck
comes is cost. I called three places, and the prices were basically
the same, in that the less you buy the more it costs per yard.
Typical costs were $52 per yard, plus $10 for each yard less than
five. This means that 4 yards is $52X4 plus $10, 3 yards is $52X3
plus $20, etc. So, buying 1 yard at a time would cost $92 each.
How to do it: Well, mine was done by digging the hole down to
4" below where I wanted the floor, plus another 4" down for the
bottom of the footings. It sounds like you need the footings four
feet below floor level? I've seen it done (in books) by removing
the top soil in the area, then have a backhoe with an 8 or 10" bucket
dig a trench where you want the wall. Put a 2X4 or 2X6 board on
edge around the outside of this hole, where you want the top of
the wall to be, and brace it good (real good). Now line the entire
area with plastic, inside the trench and across the bottom of the
floor area. This will help keep the floor dry and also keep the
moisture in the concrete while it sets. Put some re-inforcing rod
in the bottom of the trenches (footing area) and some wire mesh
across the floor area, and poor the whole thing at once. This is
how the books show it, but I would probably try to undercut the
bottom of the trenches somewhat to make a better footing, but this
may be difficult depending on how firm the soil is.
Another way would be to pour regular footings, build a block wall,
and then pour the floor. This would probably cost about the same
as pouring all at once (the block is cheaper, but the cement truck
comes twice with 1.5 yards each time, instead of once with 7 yards).
But laying 36' of block 4' high is not as easy as it looks (laying
block isn't difficult, but it is heavy.
So, if your soil is very thick and firm, you may be able to just
dig out the areas that should be cement and pour cement in. If
your soil is loose or sandy, its footing, then wall, then floor.
I've also seen (in books) pressure treated lumber foundations.
Dig the trench, put in a footing of crushed stone or cement, and
build a regular stud wall with pressure treated 2X6 and pressure
treated plywood, then backfill both sides and build a pressure
treated floor on top of it, then just regular construction on top
of that. This may or may not be less expensive, PT wood is expensive.
I'm not really making suggestions one way or the other, just kicking
around some ideas for discussion.....

48.45 | Contract out the foundation!!! | AMULET::TAYLOR | | Fri Feb 06 1987 08:26 | 18 |
| I'm currently putting the finishing touches on a 18X14 addition,
it has a crawl space foundation, cathedral ceilings, skylights,
etc. I strongly recommend contracting out the digging and pouring
of the foundation, it makes things alot easier. For cathedral
ceilings you can either use roof trusses, or do what I did and
build up a carrier beam and then attach the roof rafters to that.
Depending where you live, I can recommend people to dig the hole,
frame and pour the foundation and to pour the floor. You're more
than welcome to come take a look at the way I framed the addition,
but it has to be in the next few weeks, as the sheet rock will be
on by then. I live in Nashua near the Dunstable line.
The cement trucks did leave some ruts in the lawn, but they smoothed
out after a while. Also I would recommend going to the library
and try to get the Time-Life book "Adding On", it will show you
what you basically want to do.

48.46 | square and level | ALIEN::WEISS | Trade freedom for security-lose both | Fri Feb 06 1987 10:28 | 17 |
| Whether you mix the mortar yourself or get a truck, make SURE the footings are
level. The best way to do this (unless you happen to have a transit :^)) is to
use a water level. It's been described in here somewhere before, if you're
unfamiliar with it, write back and I'll explain. Construction is much easier
if you START level, instead of having to right it later on. Same with square,
although you don't need to worry about that too much with the footings, that
starts with the walls.
To make a cathedral peaked roof, you need to support the ridge, best done with
a ridge beam. If you go to a local mill, you can get custom cut pine beams
for about $.40 a bd ft, .50 if you want it planed. The rafters then rest on
the ridge beam. Cathedral ceilings are best vented with soffit vents and a
ridge vent. You can get styrofoam channels to nail to the underside of the
roof plywood to provide a channel for ventilation, then stuff the rest of the
cavity with insulation.

48.47 | Answers to your questions | ISBG::POWELL | Reed Powell - LCG Marketing - 297-4261 | Tue Feb 17 1987 13:59 | 105 |
| I'm on the last few legs of my 30x24 s floor addition; here are
some ideas from what I have learned.
>DOING THE FOUNDATION YOURSELF
Almost every book I read on doing construction, usually written
for carpenters, included a chapter on this, prefaced with 'this
is so you understand what they are doing; you are better off leaving
this to concrete contractors.' They are right, I believe. The
foundation's being level and correct is probably the most important
part of the construction. I don't think you will save much doing
it yourself, given the costs of renting the equipment. I just happen
to have Taylor's price sheet in my pocket:
5-7 yard dumptruck 400/week
loader backhoe 999/week
cement mixer 6 cu ft 180/week
let me stop there and tell you that you have now exceeded more than
1/2 the cost of my entire foundation, just on the rentals! Can
you use a backhoe? I don't mean looking where the knobs and levers
are, but 'feeling' how to use it - like driving a stick shift and
not thinking about when/how to shift/clutch. if not, stay away
from it, or you will be there forever trying to get it right and
not making the backhoe a permenant part of the addition.
>footing sizes
Mine were 2x2 and four feet down
>Slab and foundation at same time
All of the other reponses on logistical impossibilities of this
cover it well, but remember that the slab and the walls are very
different jobs. The walls are just level - the slab is SMOOTH as
well, and there is a whole art to doing that. In fact, the hardest
time I had with the foundation phase was lining up someone to do
the slab - most places don't do that part. I believe that at least
the top layer is also different concrete than the walls.
>Roof - tying in, removing shingles.
Yes, remove the shingles. Your gable idea is the best, rather than
a lean-to type of roof. Unfortunately I erased the tape from one
of the home shows a month ago when they did just this. You start
with a long 2x12 going from the crest of your esiting room,
perpendicular to the existing house and extending to the far side
of the addition (am assuming the final shape of your house is an
"L"), and is supported by the frame at that end. This would look
just like the gable end of a standard house, from your addition's
point of view. Your then continue this going downward and outward
on each side, with each one being a little shorter (since the current
roof gets closer and closer to the far side of the addition, which
is perfectly vertical).
>How does the roof stay together?
Use what are called collar ties, unless you really want the cathedral
to have the traditional
*
* *
* *
* *
* *
look instead of
*
*****
* *
* *
* *
look. If you want the former then I'll have to think more on this.
>VENTS
Already covered in an earlier response I think: You must have a
ridge vent if there is not an attic, and then use what are called
rafter vents (brand name is Proper Vents) along the underside of
the roof deck from the ridge vent to the soffit overhang.
My philosophy in planning was to definitely contract out the
foundation, maybe contract out the basic frame, and definitely to
do the interior finish (drywall, partitions, electric) myself.
I decided to contract out the frame, based on available time (mine)
and ability to get a crew together for more than a day here and
there. Yours is more appropriate to getting the frame up on a long
weekend. I don't know if NH requires you to use a plumber or
electrician - check with the building inspector (not the plumbing
or electrical inspectors, who may be biased or have conflicting
interests). In Mass only the plumber is required. Be sure that
you have your doors and windows at least ordered before ytou start
any framing, otherwise you will be spending a lot of time 'fixing'
rough opening sizes. Above all, I really thin you should go through
the following scenario on the foundation?
1. Will I do the foundation myself?
2. If yes, go to #1
3. Call the contractor
Look around for designers, you will draw up the plans in detail
to build from, and will know about codes and load factors for the
foundation (remember, you are the general, so you have to supply
plans to the foundation people), walls and roof. Should not cost
more than $250 or so for your job - mine was $400 for 5 sets for
the entire addition.
good luck, keep us posted!

48.48 | Do your own backfilling | VIDEO::FINGERHUT | | Wed Feb 18 1987 12:25 | 15 |
| >DOING THE FOUNDATION YOURSELF
I agree that you shouldn't excavate or pour a foundation yourself.
But one way you can save money is to backfill the foundation yourself.
I did it and I'm glad I did. The excavator would have charged me
around $600 (this is Paul Charbonneau from Pepperell, and I know
he's expensive) to backfill my foundation, so I rented a bobcat
for $150 for the weekend. It took about 2 hours to learn to use
it well. After that it's very easy. I also did some other things
(like build a boulder retaining wall), which I wouldn't have paid
someone else to do.
Also, next time I rent a bobcat, I won't have the 2 hour learning
overhead.

48.49 | footings through existing floor | DSSDEV::CHALTAS | | Wed Mar 04 1987 08:17 | 21 |
| OK, we're going to go ahead and put an addition on our
house. The fool thing is going to be 20' X 24', one storey,
gable roof (12 in 12 pitch) and sit on piers -- 7' tall
posts on concrete footings in the front, much shorter on
the back. It'll look a bit like a house on a trestle.
SO, I need to put two of these piers in the little
lean-to that houses my oil tank and is my basement
entrance. It has a severley cracked concrete floor,
so I need to dig holes in the floor for real footings
for these posts.
1). How do I make holes in the floor -- whack it with
a sledge hammer? How localized will the destruction
be (assuming I don't go wild)?
2). There is no question #2 (yet).

48.50 | Rent a jack hammer | SEESAW::PILANT | L. Mark Pilant | Wed Mar 04 1987 09:47 | 21 |
| I had to do a similar thing when I turned my screen porch into a
family room. (The old porch was rotting away, so it wasn't a big
loss.) I tore down the old porch leaving just the concrete pad.
I then had to notch it for the footings for the family room.
I simply rented a jack hammer. The one I happend to get, and WOULD
NOT recommend, was an electric BOSCH hammer. The main problem the
electic hammers have is that the on/off switch has a habit of flaking
out; usually in the on position. It dies eventually shut off, but
only after 10 or 20 seconds; can be interesting. If I were to do
it again, I you rent an air version with the compressor.
The other thing I did was to rent a power auger to dig the holes
for the footings. You can usually find up to about 12" in a one
man (operating) variety; anything bigger is usually a two man
operation. To clean out the remaining dirt, I used what is called
a sewer shovel. This is simply a shovel with a LONG handle (about
10 to 12 feet) and then business end almose perpendicular rather
than parallel to the handle. Sure beats a post hole "shovel".

one hanging up in my shed -- it was there when I bought the house,
and I've had no idea what it was for. Looked to me like a shovel
designed by someone who had no idea what it was for. In what
manner is it used as a 'sewer shovel'? Working on the pit under
a privy?
Well, so far I've got a vote either way on the electric jack hammer.

48.53 | More on electric jack hammers | SEESAW::PILANT | L. Mark Pilant | Thu Mar 05 1987 10:20 | 26 |
| RE: sewer shovel
It is primarily used to clean out the crud (branches, mud, etc)
that tend to clog up the storm drains along the side of the
road. You pop off the man-hole cover and start digging away.
I haven't seen them used much here in the northeast, but further
south, you can seem them in use all the time.
RE: Chipper vs jack hammer
There is a separate beast usually rented as a chipper. The
two are quite different in purpose. The chipper is usually
used for "chipping" small holes in concrete. This chipper is
usually the size of a reciprocating saw. The larger jack hammer
is on the order of 3 feet high, about 8"x12" at the motor end,
and about 40-50 pounds. You can use a chipper to punch holes,
but there was no way I was going to use one to break up a set
of (solid) cast concrete steps.
What you rented as a chipper may have indeed been the same thing
as the jack hammer I rented. Bottom line, though, is that you
should make sure you know what you are renting, because the
tools don't all come offered under the same names.

| I hope you realize that you should just dig as 12" hole and put in a tube!
You need a footing to support it that would probably be closer to 24",
expecially if you don't want you room to sag.
I too have used a power auger and did 12" holes to put in 6" columns. The
footings were NOT as big as they should be but I figured for a screened in
pourch I didn't have to worry about plaster cracking.
If you're building a BIG room, want SOLID footings and LOTS of them, I'd call
in a back-hoe to dig the holes. It would take under an hour, cost around
$50-$75, you won't be exhausted when the job is done and you may even
personally call me up to thank me! 8-)

| Sorry, Mark, but I was already planning on getting a man with
a backhoe to dig the holes, so you probably won't get that
phone call. I just didn't want anyone making holes in my
floor with a backhoe -- at least I don't think I do -- it's
awfully close to a rather important post that holds up some
of my house. Should I worry? Should I go for the backhoe?
And what about Naomi?

| It's getting close to that time to start making plans for pouring a foundation
for my addition. Having never done this before, I have no idea what is
required of me after I get the hole dug. Can I simply tell the forms people
where to put the foundation and have them work out the details of footing
sizes? Can I at least assume that they worry about alignment with the rest of
the house? How about the way the "new" meets the "old". I don't want any water
leaks. I've heard that diging a channel into the old concrete will allow the
new stuff to lock in! Is there an easier/better way?

48.57 | You might consider a block wall... | DSSDEV::AMBER | | Tue Mar 10 1987 09:15 | 9 |
| Concrete block walls are DIY buildable; that way you don't worry about
what the "forms" people will or will not do correctly. Of course,
a block wall may not fit your situation.
Regarding locking the new to the old, you'd be much better off to
simply butt the walls together and use a waterproof sealant at the
seam. Do not use reinforcing rods into both walls -- when/if one
wall moves, you get major cracks.
|
48.58 | things to think about | SCOTCH::GRISE | Tony Grise | Tue Mar 10 1987 10:51 | 16 |
|
Most foundation people know what size footing to use for the
thickness of the wall being poured. General rule is that the
footing be twice as wide as the wall. So fo 8" wall pour a 16"
footing.
Excavate the hole so that it is 3' wider around the perimeter
than the actual building. This is so the foundation people
can get their forms in. Be sure to leave good access space
for the cement truck.
Make sure you tar and seal the outside foundation wall befor
backfilling. Also be sure to put in perforated dain pipe
around the base of the foundation wall to carry any water
away from you basement.

I would give them EXACT plans. An out-of-whack foundation will

For footings you use 2x12's staked into the ground and tied on top

If you can find anywhere that rents them, PLEASE let me know. We tried that

I've haven't heard any talk of the building inspector as yet.....
and this amount of work should certaintly be drawn out in a detailed
plan. This plan, for different stretchs of work, can be used as
part of the contract when dealing with...for example the forms contractor.
There's really alot of work to consider for an addition attached
to an existing structure... >> Mark S...you don't really expect
us fellow noters to believe you haven't got this project well thought
out in advance...do ya. >Or are you a 'Shoot from the hip' guy who's
going to expect that the people you hire are goin' to do everything
you expect them to with or without a contract. I don't think so
from reading your previous notes. But the forms/foundation, in my
opinion is something to be left to a reputable contractor. The framing
etc. and all the rest can be DIY.
My Thoughts (and somehow I think you must have though this out)
Escavation--Location > check local codes for setback and side
yard requirements / foundation wall height...top of wall should
be at least 8" above the finished grade at the wall line. /
A 5 bag is considered minimum or most work, and where high strength
is required, a 6 bag mix is commonly used. / contract with forms
guys should indicate a requirement for the foundation wall to be
level all the way around to within 1/4" (This probably means you'll
get within 1/2", but say within 1/2" and you'll wind up >.(more)
sill plate anchors > have forms guys add these
BTW will you have a crawl space or cellar below or footings 4' below
grade capped off????? this changes things abit...e.g. use of vapor
barriers beneath the capped concrete floor...insulation etc.
Cmon....you got this all figured out.....don't cha?

| re:.-2
Actually I am kind of a shoot from the hip person. In fact, when I built
my first addition, my father-in-came up to help and demanded plans. I told him
I didn't have any! He was appalled. When we built the structure (post and
beam), I told him I didn't want to think about where windows go until I get the
roof up and can spend some time thinking about it... Fortunately, everything
worked out pretty good.
Now, I'm doing things a lot better. I have an architect drawing plans, but
we're not focussing too much on details since I fgure it'll take close to a
year before I'm even ready to think about the finish work. As for dealing with
contractors, I've never done it and feel like a babe in the woods.
Right now, I have my building permit applcation in hand, architectural drawings
underway and a wetlands hearing tomorrow nite. A small corner will be within
100 feet of a wetland and I need to get the DEQE involved (any horror stories
on that outfit?).
I know I'm being an optimist, but if things go well, I'd like to get the
foundation poured by May-June and have the summer to do the framing. As I said
before, contractors scare me and once the foundation is in I'll rest a lot
easier.

48.64 | how does one stay dry? | BOEHM::SEGER | this space intentionally left blank | Thu Mar 12 1987 12:34 | 14 |
| Something else that comes to mind is waterproofing techniques. An earlier
note referred to adding drain tiles at the base of the foundation. The problem
I'll have is where does the drain go? I fear I won't be allowed to do this
due to my proximity to a wetland (I'll find out more tonite). Therefore, how
should one best prevent leaks when drain tiles are not appropriate? Needless
to say, I'm only around 5-10 feet above the water table of the wetland now and
my cellar is dry!
My guess might be to put in a bunch of crushed stone below the level of the
footings, causing water to stay below the foundation. Only problem here is
I don't know if I'll hit water when I dig down that deep. It's a little
scarey!

| I live in Harvard which is nowhere near the sea, however, I'm right against
a very flat/low piece of land that stays wet year round. The reason the DEQE
is involved is because although my septic is already in place, ANY construction
within 100 feet (the BUFFER zone) requires approval.
As for draining the foundation, I'm kind of assuming that one might also have to
direct drainage 100 feet away which would make things very difficult. That's
why I was wondering if there is a way to keep things dry without the drain
tiles.
As for the way you've drawn the foundation locking to the footings, I assumed
(silly me) that one always poured foundations that way. From what you're saying
that may not be the case and I will be sure to DEMAND mine be done that way.

| Actually keying the walls into the footings is done only for
"light loading" situations. If the wall is going to be retaining
8' of unbalanced load (like in a full basement completely (or mostly)
below grade, then a much better job is to run vertical rebars out
of the footing up into the walls. But for 4' frost walls or crawl
space walls, it's overkill.
This is one area where the Mass building code is a bit light on
requirements. In New England, the freezing/thawing phenomemon as
well as general hydrostatic pressure can put a LOT of load on
foundation walls. Reinforcing concrete is easy to do so I usually
play it safe if there is any doubt.

off foundation drains. The board said it would be fine to drain the foundation
into a dry well and that in fact that water would eventually make it's way back
into the wetland and would be goodness. They just don't want foundation water
to directly run into the wetland.
So, what do people know about dry wells. How big are they? How deep? How
much stone do you fill them with? Drums with holes for drainage were mentioned?
Anyone ever use them? How many do you put in the well, just one?
That should get things started...

| Never dug one myself...but have a friend in Belchertown Mass. who
had such poor drainage (water in cellar) that he dug 3 drywells
which extended out from three corners of his foundation. He rented
a backhoe (which he operated himself) and simply* dug a channel
leading to a big hole (~6 ft. deep).. all of which he filled with
'coarse' stone and topped off w/ loam. I guess all you want to do is
provide an effective path for the water to run away from the foundation.
Almost sounds to simple...I'd be interested to hear how others have
done it.

48.70 | Another foundation question... | PBSVAX::KILIAN | | Tue Mar 17 1987 14:32 | 21 |
| I have a slightly different project that runs along these lines:
I am buying a house with a field stone foundation that must
be sealed before I can have termite spraying done. I have talked
to a masonry guy and got some opinions:
1. It would cost me $2000-$4000 to have him do it because it is
a lousy job (it's a crawl space) and is labor intensive.
2. I could mortar the walls myself. It would take me a long
time but would be cheap (not counting my time).
3. I could put up plywood forms along the walls (about 70 lineal
feet) and pump concrete between the stone and the forms.
I like the third option except that I have no experience with concrete
pumps. How difficult are they to use? How expensive to rent? How
much concrete can they pump? Do you rent a truck that's fitted with
one?

Concrete pumper trucks are not cheap. I believe most concrete
(ready mix) companies charge by the hour from the time they leave
the yard until the time they come home. Something like $100/hr.
Maybe different in your area.

48.72 | Spray it with Gunite??? | USMRM2::CBUSKY | | Wed Mar 18 1987 08:37 | 12 |
| Check out your local swimming pool contractor and see if they will
come in a "Gunite" (sp?) it for you. Gunite is a sprayed on concrete
type of surface that they use for in-ground swimming pools.
I have no idea if this would work or if swimming pool contractors would
even consider doing it. My brother is considering it for the inside of
his field stone foundation to stop the air in-filtration, either
he is off the wall or he has found a niche that the swimming pool
contractors may look into filling.

very expensive, if possible at all.

| The footings are now in and I expect to have the walls poured within the next
day or 2. I suddenly realized that I don't really know anything about what to
do next. From watching work in progress, I know that the pins that hold the
forms together get left behind and are usually removed in some way. Is this
hard to do? any "tricks"? I've also noticed that the holes that get left
behind are usually plugged with something on the inside of the foundation (ie
in the basement). Is there any need to do anything on the outside prior to
applying the tar?
Finally, are there any tricks or stuff to watch out for when applying the tar?
Just as a point of information, I learned something quite interesting when
getting the footings in. I had the backhoe guy come out to dig the hole and he
used a transit to make sure it was deep enough. The forms people came out to do
the footings and had no such device. They simply put the 2X10's on the ground
and strapped them together. When I asked them about leveling them they pointed
out that it isn't necessary due to the types of the forms they use. There were
some boards that must have risen 6" in 16 feet! When I expressed my shock I was
politely told "we don't do digging" (to make them level). I quickly volunteered
and did it myself.
Naturally if I do this again (which I highly doubt), I won't make that mistake
again.
The moral to this is when one contractor depends on another, things fall through
the cracks! Perhaps I should have had them write an interface spec., only then
the project would 6 months late.

Get a 3/4" pipe about 18" long and put it over each pin, and bend
it back and forth to break it. The pipe is to give you leverage.
The pins have notches on them, and
you'll quickly see which direction to bend them to get them to break
the fastest. If you use copper pipe, you'll go thru a few pieces
to do the whole foundation.
> I've also noticed that the holes that get left

Yes. Plug them on the outside too. I've used both roofing cement
and hydraulic cement, and found that hydraulic cement works best.
Make sure you break off the pins on both the inside and outside
before plugging the holes, because if you plug the ouside, then
break off the pins on the inside, the force of breaking them could
loosen the plugs on the outside.
> Finally, are there any tricks or stuff to watch out for when applying the tar?
Don't put it too high. I think it's better a foot too low, than
too high. The foundation probably won't leak 1 foot below grade,
but a foot of black tar around your house won't look too good.
> The moral to this is when one contractor depends on another, things

I used Guiguire & DuFresne from Fitchburg. The guys who did the
footings didn't do the chimney pad because "they didn't have any
extra wood". They said the wall guys would do it. When the wall
guys came, I wasn't there, and they didn't do the chimney pad
because "it wasn't their job".
They had to come back later just to do the chimney pad.

In my experience, you absolutely MUST make sure that the metal pins
aren't exposed. They WILL rust and leave holes through your
foundation. Patch them thoroughly on the outside.
Don't skimp on the tar. You want a perfectly seamless application.
Do it twice or even three times. Really lay it on. (I like the
idea on .17 about staying down below the ground level, but personally,
I'd cut it closer than a foot.)
Once you have a couple of tons of backfill in there, you're stuck.
Don't even think of scrimping before that happens. Spend a day,
overkill on the application, wear disposable clothes, and then relax
for a couple of decades, secure in the knowledge that you did your
best.

| For leveling the excavator should do a reasonable job which it sounds
like he did if he used a transit. The forms crew should also be
concerned with level, especially with the footings.
What they do usually is set up the footing boards in the hole. Then
they find the lowest board using the transit and snap a chalk line
starting at the top of the lowest board on all of the other boards. So
even though the boards rise and fall with the grade, they will be able
to pour to the chalk line for a level footing.

48.78 | Tips on tar | BARNUM::BROUILLET | Don Brouillet @ MRO | Fri Jun 12 1987 13:17 | 11 |
| One thing you may want to try is thinning the tar. I tried heating
it when I did mine, and that helped somewhat, but later when we
coated an underground oil tank with foundation tar we hit on the
idea of thinning it with paint thinner. Works great - you can even
put it on with a roller, and it flows better over a rough surface.
It seems that all the thinner evaporates, and the tar coat stays
intact when dry, but you'll probably have to do 2 or 3 coats to
build up the same thickness you'd get by just brushing on the tar
tight out of the bucket.

48.79 | Insulation after tar? | CHAPLN::SULLIVAN | Mark Sullivan | Fri Jun 12 1987 15:47 | 19 |
| Since I will be doing all of this in another month (I hope!), I'd
like to add some more questions.
After tarring the foundation, I am planning on adding the blue
insulation sheets. I have seen this handled two ways.
1) Add insulation sheets and break off above ground pieces after
backfilling.
2) Leave the full sheet and coat with a stucco material to cover
it.
Any opinions one way or another? Is the outside isulation worth
it? (Some claim no but I find that hard to believe). How much per
sheet?

I'd vote for continuing the foam clear up to the sill plate. After
all, the concrete above the ground is the part most exposed to cold!
A couple of feet below grade and you're above freezing year round.

Now you have a 1" ledge for stuff to accumulate on, or are you planning on

On a related topic, what is the method for putting the foam in place? Do you
simply tar the wall and stick it to it (this was what they did when building
LKG2). Seemed to make enough sense, but then again, one never knows with all
the shortcuts builders like to take...

| The siding should overhand the foundation a little anyway, so I
don't think the foam would stick out a full 1". But that is a
problem. Best thing would be to plan ahead and build in extra
overhang when building the house. Lacking that, I think I'd put
on some flashing, up under the siding and down over the foam.
You'd probably want to get it professionally bent at a sheetmetal
shop, so it wouldn't look sloppy.

When I signed a contract with a forms company, the contract

| Regarding the foam on the outside of the foundation:
DEFINITELY run it up to the siding if you can. A 10" concrete wall has
approximately the same insulating value as a double-pane window - about R1-2.
And the part above ground is the part that loses the most heat. We have 3" of
foam on ours above grade, and 2" below - and, yes, we had to put the sills on
overhanging the foundation to allow that. You should also definitely have a
metal barrier between the foam and the wood, as a termite shield. For termites
to get at your house, they have to have a sheltered means of getting from the
ground to the wood. On a normal concrete foundation, you can see the little
tunnels that they build, so you know they are there. With the foam, they could
come up behind the foam and you'd never see them. You need the metal shield to
keep them out.
And for sticking the foam to the foundation - don't just stick it in the tar -
the foam will disolve if exposed to the petroleum fumes. In fact, you should
let the tar dry for at least several days before putting up the foam. Or, as
an alternative, you can find latex tar (hard to find). There are also some
latex construction adhesives to use for sticking it to the foundation. And Dow
makes a product (Insulcrete) specifically for stuccoing the exterior (but watch
out, it's expensive).

The Insulcrete stucco is VERY hard, and will stand up to most abuse, even though
it's only a 1/8" layer. Of course if you really ram it, it will crush,

Thanks for all the help so far. One question which still has not
been addressed though is, Is it worth it?
For the house I'm building, it would cost about $400.00 for the foam.
Given that the gound maintains a 50 degree temp. below 4 ft. for
most of the year, have those of you who have insulation outside found
that your cellars are appreciably warmer/drier? On the scale of
house building costs $400.00 is a drop in the bucket. But all the
$400 add up and there is also the time to put it on.

48.89 | yes, both, warmer ==> drier | SUBSYS::FILGATE | | Mon Jun 22 1987 16:47 | 12 |
| > that your cellars are appreciably warmer/drier? On the scale of
Both. The walls are warmer, thus in summer they don't sweat (condense
water because their temperature get below the dew point). The cellar
hangs at about 65 with its heat off (upstairs is 70, cellar windows have
storms, bulkhead has inside insulated door). Bear in mind, concrete
takes a long time to dry out after/as it cures, but afterwoods there is
NO sweating even with cellar windows open in the current muggyness.

48.90 | connecting rods and termites | BOEHM::SEGER | this space intentionally left blank | Thu Jul 02 1987 09:27 | 35 |
| The foundation is in! I can't believe how quick concrete sets. They poured
Tuesday afternoon and removed the forms 8:30 AM the next day!!!
Anyhow, this leads to two more questions, the first dealing with the rods that
hold the forms together. Somewhere in a previous note someone said to bend them
and they break off. wrong (sort of! I tried that with mine and the metal
breaks off arouns 1/4" beyond the wall. I suppose this would be alright on the
outside wall but on the inside wall I'd like it flush. Also, I'd think it would
be a pain putting on the hydrolic cememt if I couln't trowel it flush (as in
jointing compund).
Question number two is about termite shields. Paul had mentioned them being a
must if you run your insulation up to the sill. Is this simply flashing? I saw
in a book that you put the shield under the sill before bolting it down. My
question is where does it go from there? Can you simply bend it down over the
insulation? I've heard of termite sheilds that prevent termites from getting in
even if they try tunneling and this certainly wouldn't prevent that, but I think
the idea here is to simply stop them from coming up from behind. One would
still need a visual check to catch them tunneling.
Is this essentially the idea?

of the notches are flush with the outside and inside of the walls.
Somewhere in this file, someone drew a picture of the actual shape
of the rods. They're designed to be broken off flush with the walls.
If they really only stick out 1/4", that's not bad. You can cover
it with hydraulic cement to smooth it out over an inch or two.
Don't apply the cement until both sides of the rod are broken off.

wall when we followed the advice of just bending them back in forth.
Then my dad tried removing the cones described in .36 and the rods
snapped off inside the hole left from the cone. See if you have
cones around the rods if you do remove them then bend the rods,
you will have to fill the holes but atleast you don't have rusty
rod ends sticking wait for you, your kids or your SO to brush up
against and get cut!

| Even though they removed the forms the next day, the concrete is still
curing. I would wait a few days before I started snaping the rods if at
all possible. Sometimes when snap the rod end off they can pull through
the foundation a little, then you have a 1/4 exposed on one side and a
1/2 recessed on the other. If this is the case, just bang them back in
so that they are fush on both sides.
I had a foundation poured last December. They poured in the afternoon
and strip it the next morning! The wall was steaming after they
stripped the panels off.

approximate amount of time it takes (or is that should take) for the
cement to properly cure. It was quite hot and sunny for the first week
so we thought it especially important to keep the foundation as wet as
possible then. The rods were still in that entire time and we just
began breaking them off yesterday. Perhaps a bit overcautious but we
decided the foundation is too important to screw up so we'd go by the book.

the house whether there are nuts holding the sill down or not.
I believe that the houses shown after sliding off the foundation
did not have bolts placed in the cement to keep the sill from sliding.
I still would put the nuts on.
As for replacing the sills after the nuts are rusted, just use pressure
treated wood for the sill when the house is first built, and you'll
never have to replace a rotted sill.

I spent the last couple of days putting on the deck and since the bolts are
about 2" from the outside, one would think there'd be no problem but...
On the sidewalls where I framed using double joists, I had to notch the joist to
fit over the bolts so nobody could get them off anyways. I don't know if I had
to double them, but it made me feel better.
re: insulation
I'm still a tad puzzled on how to put this stuff up. Sounds like first I plug
the holes from the framing wires (or whatever they're called). This leads to a
question - I bought some water plug and it says not to trowel it on because it
won't bond that well. I had planned on using a putty knife and doing something
like a jointing compound application. Is that ok?
Anyhow, the next step is to put up the plastic to cover the tar. How do I make
it stick? Will it self-stick?
Next comes the styrofoam. How to I keep it in place during the backfilling? I
imagine I could glue the top of it (part above the tar), directly to the
foundation. Would that be enough to make it hold? I suspect that backfilling
can be quite an earth-shaking experience. 8-)

re: .52 - patching the holes in the foundation.
My husband broke rods off and I'm patching the holes on our new

This cement hardens very quickly so I mix up only enough cement to
equal a wad that fits in my hand. I have rubber gloves on and use only
my fingers for application and smoothing. I get about 10-12 holes
filled per wad of cement (because any larger wad and it got too hard).
It really is quite easy and it looks nice.
I'm also chiseling off the extra globs of (now) dried cement that
had oozed from the forms. I don't know if this is really necessary

tape is also handy to hold it together, especially at the corners.

The current flyer lists two books of interest:
Concrete Form Construction by Cairl E. Moore,
8x10 paper 218 pg Cat no. 561 $18.50
The catalog blurb:
"Obviously, if you're making concrete overshoes for your
mother-in-law, all you need are a couple of pails. But if you're
going to pour footings, walls, piers, stairs, a patio, swimming pool,
basement, garage floor, or a driveway, you should have a copy of this
excellent technical school textbook. You'll learn how to build forms
from common materials, use prefabricated forms, use clamps and toggle-ties,
dampproof foundation walls, anchor sills, form up stairs, and much
more. This book is somehwat expensive, but good. If you're going to
spend a small fortune on ready-mix, this book is cheap insurance that
you'll be doing the job right. Easy to read. Well illustrated. Get a
copy. Oh! and give your mother-in-law my regards."
Concrete Technology by George White,
8 1/2 x 11 paper 136 pg Cat no. 522 $14.95
The catalog blurb:
"It's amazing how little people (and that includes you and me) know
about concrete. Some people even think that concrete dries by evaporation!
If that were the case, the thousands of yards of concrete in dams would
have taken years to set up!
Find out what concrete is, Portland cement is, why it's called that,
why concrete must be mixed and worked the way it is, and a whole lot
more.
Chapters include: uses of concrete, Portland cement, mixing water
for concrete, aggregates, air-entrained concrete, selection and design
of concrete mixtures, sampling and testing of plastic concrete,
ready-mix, job mixing, tools for placing and finishing slabs, placing
concrete, finishing, curing, joints, estimating, reinforcement,
concreting during hot weather, and during cold weather.
This book is rather small, but it's loaded with info on an
extremely useful construction material. You should know what's here.
It's simply explained and easy to read. After all, this is a technical
school textbook. That also makes the price higher than it should be.
But I can't do much about it. Practical info throughout. Consider it."

| Re. The fumes from any petroleum based products will melt the stryofoam.
I recently removed the foam insulation from the one end of my house
where an addition went. I had previously (6 years ago) painted the
walls with the foundation tar and then used "globs of asphalt cement"
to hold up the foam sheets. When I scrap and chipped off the foam
sheets, there didn't appear to be any damage to the foam from either
the foundation tar or the asphalt cement.

note! You may have saved my dad's life, or at least his mental health
and pocket book.
He is putting up a two story 18x11 addition and was going to do
the foundation himself. I printed the replies to this note (checking first
for company confidential material) and took them to him. The cautions
urged here coupled with the $600 DEPOSIT a rental place wanted for
just the form brackets and the cost of the plywood for the forms never
to be used again convinced him otherwise. So we "just" did the
footings and let the boys with the big truck (that crushed the
driveway) do the rest.

48.117 | Where can I get termite shield | VAXINE::COUGHLIN | | Tue Aug 04 1987 22:49 | 10 |
|
Are "termite shields" actually sold in stores or does one have to
buy flashing? If one has to use flashing, does flashing come in
plane L shape -- and how long do pieces come. How reasonable is
it to use sheets of aluminum? Could the sheet be cut and L shaped
precisely enough by a DIY or is this something we'd need to take
to a sheet metal shop. I'm really looking for the best but easiest
(naturally) fix.
Thanks for any advice....Kathy

48.119 | | BEING::WEISS | Trade freedom for security-lose both | Wed Aug 05 1987 09:24 | 8 |
| Just buy plain aluminum flashing at any lumberyard. You want it wide enough to
be able to drill holes in it an set it over the anchor bolts on the foundation,
and have 1/2" or so past the edge of the insulation. (assuming new construction)
To bend it, just clamp it between a couple of 2x4's and bend it over with a
hammer - the siding is going to cover it so it doesn't need to be a nice
aesthetic bend.

Can you suggest :

| Here are some magazines that I like to read on a regular basis:
o Practical Homeowner (formerly New Shelter) - a number of back
issues dealt with additions. Try your local library.
o Fine Homebuilding - most of their additions cost big bucks
but it's nice to dream. You might get some good ideas.
If you can stand Bob Vila, get a copy of his "This Old House" book
or video. I believe he deals with additions somewhat.
Finally, if you're really concerned about matching the original
style of your house, it might be worth it to spend the extra
money for an architect to draw up the plans for your addition.
I did an addition two years ago and wish I had seen a architect
as there were some things I hadn't thought of that would have made
for a nicer finished product.
Best of luck.

48.125 | Notes from someone still emotionally involved | OBSESS::COUGHLIN | Kathy Coughlin-Horvath | Wed Jan 20 1988 15:41 | 59 |
|
I am 75% through an addition. We are actually planning this as phase
1 of a ~5 year whole house renovation/additions. We started with
the easiest piece, a passive solar 18 x 26 family room. My husband
and I had several..ahem "discussions" about whether to hire an
architect because this part was very straight forward, nothing fancy
or difficult. (One of us thought an architect would be a waste of
money right from the start.) We interviewed 2 architects and we
decided architect services would cost too much for this "very simple"
addition. The 2 quotes were based on a range of 6-10% of total
addition cost for architect 1 and 5-7% of total addition cost for arch.
2. The percent range would depend on difficulty of job. Trick here
was both of these guys decided what the total addition cost to us would
be (a figure that felt like they were pulling out of thin air). The
second guy was much more reasonable in his cost estimation and more
willing to negotiate (younger and more interested in the work). For
example, arch 1 told us this addition would cost us 85K when we were
thinking around 25K. It became clear it didn't matter that we had all
our quotes, material prices, etc. to back up our 25K cost. He was
still going to come to a figure of 6% of 85K.
Now that I'm 75% through this "simple addition" I am a lot wiser.
Even though my husband and I had lots of renovation experience and
did tons of homework, we still missed so many things that have cost
us extra money, mega stress, and lot longer construction time. (I
think I've read this many many times in this notes file.) Considering
all that, architect number 2 prices weren't all that unreasonable.
I realize now that part of the architect problem we had was not
knowing how to talk with them or know just how to use their
expertise (or maybe we're the types that have to learn by doing.) The
best plan probably would have been for us to draw up our own plans
first and then consult with the architect for their approval, to fill
in holes. If we used the architect just for consultation he would
have charged hourly. When we get to phase 3 of our addition, (IF
we get that far) we will "definitely" use an architect. I had read
every book I could find on building, but I really didn't pay much
attention to the sections in the books about how to work with an
architect (or the variety of ways which you can use one).
Much success of the building/additon is in the planning. We did
tons of planning and still made tons of mistakes. I couldn't
afford to buy all the books and magazines in print on building, but my
public library is filled with them. I strongly recommend you utilize
the public library for your research.
The "This Old House" is not one video tape to borrow. It is a PBS
(Channel 2 or 11) program on weekly with different topic(s) covered
each week. The show is talked about more in other notes.
Finally, you really don't HAVE to do all this homework. It does
take LOTS of time. You can just go hire an architect to "come up with
something" and hire a contractor to "put it together" but in my
opinion innocence is sure suicide in the building trade. You are far
more apt to pay more and get a lousy job when you don't know what you
want, what it's supposed to look like, what materials you want the
builders to use, how it's done, and have a rough idea on how much it
should cost.

48.126 | Solve my problems about adding my addition | MSEE::CHENG | | Tue Feb 02 1988 11:28 | 54 |
| My house is a two story center entrance colonial with full basement. I'm
planning to build a 20 x 26 addition attached to one side. This is the
floor plan :

front entrance
What I plan to do is to build the addition attached to the left
side of the house. It will be 20 ( outward ) and 26 ( depth of the
house ). I would like to knock down the left-side wall of the living
room. The current liv-rm size is 12 1/2 x 14 1/2. I would like to
extend it out 6' to make it a 20 x 12 1/2. The rest of the addition
would be a 20 x 12 1/2 bed-room and a 14 x 12 1/2 bed-room.
Questions:
1. Can the left-side of the living room wall on the first floor
be knocked down and move 6' outward without putting up a header
and supporting columns.
2. The addition will have a full basement. So I need to cut an
entrance ( 4' wide ) through the exsisting basement to gain
access to the additional area. The exsisting basement is field
stone type of foundation wall. Is it safe to cut through the
wall ?
3. How much would it ( roughly ) cost to excavate and build the
foundation and the wall of this size ( 20' x 26' ) ?
4. The addition will be one story ( floor ) only, so I will
subcontract out to frame the addition. I plan to do the siding
roofing, interior wall myself. How much the framing would cost,
assuming 2x4 construction ?
Thanks for any help ?

48.128 | utility lines | MSEE::CHENG | | Tue Feb 02 1988 14:02 | 12 |
| Question about utility lines :
The house is in the city. So there are sewer line and water
line comes into the house from the main line. I went to city
engineering department trying to find out how and where they
come into the house. They don't know anything about the water
line, know the direction ( roughly ) but not the depth the sewer
line comes into the house. I don't feel comfortable to have
someone excavate the ground without knowing exactly where the
water line and sewer line are. Cause they may break/damage the lines.
Anything suggestion on how to handle this ?

| Finding the water line is usually easy. There should be a cap over
the shutoff value near or in the street. The line probably makes
a moderately straight line from the shutoff to where it emerges
in the basement.
(Bad story: the town cut mine once when digging in the street. Our
soil was loose sand, the hole in the basement wall was 6" in diameter
and the shutoff was burried under lots of ice. Very big flood!!!!)
You should be able to locate the sewer in the basement too, but
not in the street. If the street had sewers when this house was
built, the sewer probably goes relatively straight out. Also, the
city should know the depth, as this system works on gravity with
the highest possible point being the house end of the pipe.

| Are you saying some states are forcing people to use 2X6's? This sounds rather
unusual to me. The only reason I could think of for doing that would be to
encourage more insulation, but it's well understood that there are many ways to
improve the R-Value of your walls without going to 2X6's. Now if states were
mandating greater R-Values, I could begin to understand that one.
Are you sure of your facts?

48.132 | no easy answers | NSSG::ALFORD | | Wed Feb 03 1988 09:44 | 29 |
| I just completed a 12x28 addition to my house, and priced both the
"finished" job and "just framing" .... with costs ranging from
about $30/sq.ft to $60/sq.ft. I would imagine with you doing alot
more of the work than I was willing to do you might be able to get
your framing done for less than $30. Also, of course, alot depends
on where you live...these were Burlington Mass. prices, so if you
are further out, your costs may be considerably less.
As for all of the details on the underground stuff...I think the
best bet is to get a good foundation person, explain your concern,
and be there when they are digging. I also found that the city
had little to no information on *anything*...talk about a bunch
of wasted time and energy trying to work with the city "officials"!!
I opted for the 2x6 construction for the support, to make the
insulation better (yes, I know you can do it in the 4" range,
but it just seemed easier to go with 6")...and as my house was
originally built 75+ years ago it used weird sized lumber--
like 3x8 or something...so matching up walls etc was easier.
Of course, I didn't realize what problems it would cause with the
windows!!! They are typically made for 4" walls, so had to have
extension jambs built, etc. ... but all the interior woodwork was
custom design anyway, so it wasn't too bad.
I wish you luck!! Hope your contractor is **much** better than
mine was!!

re .5: Case in piont: My parents bought a new house in Biddeford
Maine (split entry ranch) and it came with 2x6's. When my father
asked the builder why 2x6's he said that Maine is going for higher
R values and that other states will probably be following.
This goes along with what the framer that framed my addition said.
He said that he does work in Maine and they require R-19 in outside
walls so he just does ALL his framing using 2x6's in Maine,N.H.
and Mass. He said that the easiest whay to get R-19 is using 2x6's
with 6" insulation in outside walls. He is the one that told me
that Mass. is thinking of making this requirement. Of course he
could also be yanking my chain.

48.135 | Get a General Contractor | RUTLND::SATOW | | Thu Feb 04 1988 11:07 | 35 |
| The fact that you are asking for recommendations on all the trades
leads me to believe that you are planning on acting as the general
contractor. Don't do it. Find a general contractor (who may also
be the carpenter) and let them find all the others. If you act
as the general contractor, you will
- have to act as a scheduler. With a job like this, there
are some things that have to be done in order, and some
things that don't. Since you don't know that "critical
path", you run the risk of having one tradesman ready, but
the project not being ready for him. And since he has several
jobs lined up, you may lose him for a long time. In addition,
tradesmen are notoriously independent; they are notorious
for not showing up when they say they will. They will drive
you crazy.
- get gouged. A general contractor knows how much a given job
will cost. If you don't, they will charge you a whole lot
more than the going rate.
- end up in the middle of disputes, both professional and personal.
We had an experience where we only were dealing with two
subcontractors, and ended up mediating both types of disputes.
- not know anything about the reputation of the tradesman's
work.
So my advice is to ask for recommendations for general contractors
(which unfortunately I can't provide in your locale), talk to and
get quotes from several, ask for references and check them out.
Select one, and let THEM get the plumber, electrician, etc.
Good luck with your addition.

Just to make sure you hear both sides:
I acted as GC for my house and had very few problems. I guess I
was prepared, and never really expected any contractors to show
up on time, etc., so I planned for that. You just have to accept
the fact that a contractor won't return your phone calls, however
they don't mind if you keep calling them until you reach them.
I got a couple estimates on most of the work although some contractors
I got on recommendations, and knew that the prices was good. I
might have just been lucky, I don't know. But I've heard enough
horror stories about problems with GC's that I didn't think they
were worth the 20% that they charge, just to make phone calls.
If I were to do it again, I would never consider hiring a GC.
> - not know anything about the reputation of the tradesman's
> work.
How does hiring a GC tell you anything about a tradesman's work?
A GC is going to care less about the quality of the work than you
do, so you'd have a better chance of quality work if you pick the
tradesman yourself.

48.137 | architect too | MSEE::CHENG | | Thu Feb 04 1988 11:42 | 6 |

I will also ask recommendation for architect, and GC. I will need

architect does that at a high price, or can GC or any other trademan
do that and is acceptable by the city ?

| re: .11
If it's a "simple" addition, an architect isn't necessary. The
general contractors and tradespeople deal with the town all the
time, so they know what the town requires. If you can, get the
permit in the name of the GC or tradesperson. That way, if something
is not done according to regulations, they will come after the
GC/tradespersion, not you.

Before I built my addition I wanted to know how much it would
cost to have a GC to it. I got 3 estimates that ranged from $15,000
to $30,000 !!!!! This was for a 16X20 room off of one side of a
cape. I ended up building it myself and also put a full bath in
which was not quoted in the GC price. It cost me $13,000 for everything
including the carpet, blinds towels.......EVERYTHING.
I still can't believe there was such a difference in price amoung
the contractors. If you look at note 1478 and a few replies later
I entered in the actual costs of everything.

door ( walkout ) is leveled with the drive-way. My question is :
Where is the frost line ? It is relative to the top of the left
side yard which is 4 ft above ground, or relative to the drive-way
which is leveled with the basement door ( which is about 3 inches
above the basement floor. This would determine how deep I have to
excavate.

I disagree. No matter whose name the permit is in, if there's a building
code problem on your property, you have a problem. The inspector will give
his/her instructions to whomever is present at the inspection, regardless of
whose name is on the permit. The financial arrangements for the work to
carry out those instructions are then between you and your contractor(s).
(In a clear case of the contractors screwing up, they should make good for
free, but if you specified something that doesn't meet code, they have a
good case for charging you more.) The point is that the name on the permit
doesn't change anybody's legal responsibilities.
However, if you need to change contractors in the middle of a project,
things may go more smoothly if the permit is in your own name.

Perhaps this varies by town. This was the advice given me by my
town's building department. But I agree that if something isn't
built to code, you've got a problem, regardless of whose name is
on the permit, and that if it was their screwup, they should make
good. It seems to me that if the permit is in a professional's
name that they have just about NO excuse for doing something against
code.

| Re: Frost Line
The answer is BOTH! The frost line is the typical depth that the frost
will penetrate the ground in your area. Usually related to depth but
also depends on soil composition and ground cover and it follows the
contors of the land. So four feet down from where ever your standing is
the frost line, NOT four feet down from the highest area of your yard.
Another thing to consider is soil type and ground cover. In your case
your lawn area may be frozen down to 3 feet while the soil under your
driveway could be frozen down to 4 or 5 feet. Because your driveway
dosn't have a layer of insulating snow over it.

Re .-1
The contractor putting in the foundation will know how deep
to put the footings, thats pretty standard.
As far as what the exact line will be there really is no exact
line. When my addition went in I said I wanted the foundation to
be 16x19 and thats what I got. My house is 24 feet wide so the forms
guy centered the foundation 4 feet in on both sides.
Most additions do not require plans. The building permit form
is very extensive as to what your going to do. You also have to
include a graph paper outline that describes how the addition will
look in relation to whats there. They will also want to see where
the septic system or sewer line is on that drawing.
If the addition is just a standard box off one side of the house
you can just about give the inspector a drawing on a napkin and
they will give you the permit. They just want the money for the
application.
As far as the vocation school doing this, HA !
They do excellent work but your name gets put into a hat with everyone
elses name then they pick one. You must verify that you are able
to pay for the complete project. They are very selective in the
type of job they accept.
I went thru all this last year when I built a 16x19 addition
for my cape with a full bath and the whole process was real easy
!!!!

| re: Building Permit
In our town I had to include a set of prints with my permit including a
structural x-section in 3 places. Apparently they figure they can "trust"
the pros to do it right and someone like me needs to go the extra distance to
prove I know what I'm doing.
I know someone who wanted to save the expense of an architect and went to some
kind of designer who charged less and wasn't the real thing. Only cost him $700
(for a 50K addition), but when I looked at his plans that were WRONG (a wall was
misplaced throwing off the entire drawing).
However, if you think you know exactly what you want, perhaps finding someone
who does plans (such as a draftsman) will suffice.
As far as "trusting" the foundation people to do it right, BULLSHIT! I did and
wound up with footings that are a couple of inches too high. Doesn't sound too
bad, but the result is that I'll have a step separating my new cellar from the
old.

48.149 | interior design ? | MSEE::CHENG | | Wed Feb 10 1988 09:13 | 23 |
| re: .22
I have a rough idea of how the addition should be and can draw it
on the paper too. Its the DETAILs that I may not have. e.g. where
is the opening for windows/doors, what's the exact size for the
opening, and how they should be constructed, how deep to excavate
? and to form the footing, and to build the wall so that the finished
new floors ( basement & first floor ) are even with the old floors.
Its some of these little details, if not correctly done up front,
may cause big problems later. If the designer draw the plan, I should
be able to look at it and see if that make sense, and yet I don't
have enough knowledge to draw the detailed plan. Sort of like a
non-programmer who can't write good programs but can look at the
code to see if they make sense.
The floor plan for the addition that I have in mind is : the 12.5
x 20 living room is surrounded by three bedrooms ( one on the back and
two on the right side ), the left side of the living room has big
picture window, and a large entertainment center is against the
front wall. I think it may look rare with 3 bedrooms surrounding
the living room. Are there trade professonals that help designing
interior for residential house ? and how do they charge for service
?

48.150 | Opinion on a (lally columned) $32K addition needed | SLDA3::MATHUR | | Thu May 05 1988 19:51 | 56 |
|
Well, after a lot of looking, designing, and re-designing with various
contractors, we've gotten an estimate that seems to be somewhat within
reason. I'd like to run it by y'all to see wht you think because
we're having second thoughts on whether this job really should be
*that* much...
Here's the deal: It's an addition of 2 rooms + 1 laundry room.
The rooms will be added onto the second floor of the existing house and
will be on lally columns. The space beneath the newly constructed
addition will be sort of like a crawl space about 5-5� feet high. The
sizes of the added rooms are as follows:
- (1) 12 x 14 ft room + (2) 6 x 3 closets
- (1) 12 x 12 ft room
- (1) 9 x 8 laundry room
The reason we went with the columns is 'cause it was found to be
a lot cheaper and yet seemed to deliver the same functionality as
a full foundation would have. By the way, the columns will come
1 foot above the ground and then the wood frame will begin. The
exterior will be siding starting from 1 foot above the ground, so
as to cover up the columns completely. The space between columns
on the ground will be blocked off with either cement blocks or
a concrete 1 foot high wall (*not* dug into the ground). So the
whole structure will be homogeneous looking at least.
The above is what the addition part of the job consists of...there's
also some other work that is a part of the contract. It is as follows:
- Installation of a bathtub in an existing � bath;
- putting up some walls and cutting a door or two (no big deal,
structurally...);
- replace oil furnace with new one;
- the roof on addition will be flat, not taken off the existing
roof (he says anything else will jack up the price).
All rooms are to be fully carpeted (no hardwood floors) and painted.
Exterior of new portion of house should match the existing portion
(i.e. siding, color to match).
# of windows = 7 Andersen, double hung
# of doors = 5 (regular stuff - nothing special)
The price? $31,900.
This includes architect's drawings, running around for building
permit - basically a turnkey job (supposedly).
Square-foot for Square-foot - is it on the level (no pun intended)?
Will the flat roof give grief in a little while?
Thanks for any information,
Raj

48.151 | | DICKNS::WELLCOME | Steve Wellcome (Maynard) | Thu May 05 1988 22:53 | 16 |
| I come up with a wild-ass guess of $32,200. He's probably not too
far out of line (not that my guess is worth much).
Figure for openers that $60/square foot is probaby a pretty good
rough estimate for the addition, which works out to $25,200. I
get anothr $7,000 out of the additional work you're having done
too. Architects ain't cheap either, remember.
It's hard to judge whether it's reasonable or not because it all
depends on whether or not he does a good job. If he does a good
job, a price that is slightly high doesn't matter much. If he
does a bad job, a rock-bottom cheap price is still too much.
Personally, I wouldn't get a flat roof; I'd tie it into the existing
roofline, just for aesthetics and (probably) better resale value
if and when you go to sell the place.

48.152 | 1 opinion | VLNVAX::SUMNER | Senility has set in | Thu May 05 1988 22:56 | 20 |
| It's difficult to to give an acurate assesment like this but
just to give you some idea...
Using your figures of added living space, you are adding about
420 square feet. If you use $60 sq/ft as a benchmark for a turnkey
project that comes out to $25,200.
A new furnace should run you about $2,000 installed for an
efficient model.
$31,900 - $25,200 - $2,000 = $4,700 left over for your bathtub,
extra doors & walls, architect's labor and permits.
Granted the builder is going to make some money but it doesn't
sound abnormally high to me. How much value will the project add
to your house? Keep in mind that all of these figures vary
tremendously on geographic locations.

48.153 | Columns ==> no massive digging ==> less $$ right? | SLDA3::MATHUR | | Fri May 06 1988 09:03 | 18 |
| Thanks .1 and .2 for your inputs.
The house is in Arlington should bring back a good portion of our
investment through time and rental income (it's rented out).
The point I was concerned about most were the fact that it was on
columns. Since it's on columns, why should construction price still
be $60/ft� ?? There's no foundation digging involved, much less concrete
to be poured - so that should be a considerable savings.
(BTW, each column will be five feet high - 4 in the ground and 1
ft. above ground. The wood frame starts from there. There'll be
a 2 foot square base at for each column, four feet into the ground.)
Secondly, since he's proposing a flat roof, shouldn't that be cheaper?
How much more should we expect to pay for a sloping roof?

Another vote against the flat roof, unless you want to deal with
roof maintenance every couple of years (frequency increases with
age of roof) and water leaks which *will* eventually happen. In
my opinion they also make additions look like cheap additions.
As for the columns, what does the local building inspector say about
this setup?

>> If you're not sure the estimate is good, get two more.
We've dealt with 15 contractors and have gotten estimates from 6
of them, ranging from $25000 to $68000. This person was in the
middle-of-the-bunch and seems to be on the ball.
My main point of concern here was the fact that we were going with
the columns in our design. Why should construction costs be $60
per ft� even though there will be considerably less excavation and
pouring of concrete?
OK, I'll see what he can do to put a sloped roof instead of a flat
roof. I have a lot of reservations about a flat roof, especially
with the rough winters we have here...
What if the new roof was sloped off a parapet adn not the existing
roof? That way we'd get a sloped roof and still not have to really
touch the existing roof, right? That shouldn't be more expensive
and should solve our problem. The only negative thing I could think
about this is that of water (or snow) build-up at the junction of
the parapet and the old roof. Here's what I think that design would
look like:
new roof - sloping normally
/ from the parapet

| x

Oh yeah, btw, the contractor will put 8 inches of insulation
in the new floor -i.e, 6 inches regular (?) and 2 inches rigid.
That should be enough, right?
Boy, if the foundation really is $2000 (does that include digging
too? or only the concrete?) then we have a real rip-off on our hands.
But then again - there were two others who gave estimates in a the
same ballpark range.....So what's the deal?
|
48.161 | | DICKNS::WELLCOME | Steve Wellcome (Maynard) | Fri May 06 1988 12:03 | 24 |
| I doubt that you're saving that much with the columns. The contractor
will need to get a machine in there for a day to dig the holes.
In the same day he could probably dig for a real foundation.
He'll need to have a concrete truck come to pour the footings
for the columns. For a couple hundred bucks more in concrete
he could pour a continuous footing. Somebody will have to set
up sonotube or other sorts of forms for the columns; a similar
crew could probably set up prefab forms for walls in about the
same time. The concrete truck will have to come back to pour
the columns; it could come to pour a wall just as well. Your
main saving is going to be in the cost of the concrete, little
or none in labor or machinery time. It might be $1000 less, maybe.
Materials in building a house are CHEAP by comparison to labor and
machinery costs. I don't think you're saving much labor or machinery
cost.
Spend a few extra bucks to blend the new roof into the existing
house in a finished and aesthetic manner; otherwise the whole thing
is going to look like hell. The n+1 cost of doing it while the
addition is being built is a heck of a lot less than trying to fix
it up later. Do what you REALLY want the first time around, even
if you have to scrape a little. If you can't do it all right now,
I think you'd be better off to postpone finishing off one of the
rooms inside, perhaps, rather than trying to skimp on the foundation
or the roof.

a total of around 85' or so (including a bulkhead and a bumpout) for around
$3200 which is a little less than $40 per foot. The floor cost around $700
and the excavating was around another $700 including the backfilling. I also
had crushed stone under the floor for another couple of hundred bucks.
Finally, I spread all the fill around the rest of my yard rather than trucking
it out.
So, based on the size of your requirements you can make the appropriate
adjustments.

This is right about the realative costs of columns and foundations.
The price differential isn't as great as you think.
Also, tie in the new roof to the old one. It shouldn't be that much
more money and the risk of not doing it is VERY substantial. You'ld
(You'll??) be amazed at the amount of damage a small leak can do

And, the flat roof will be more expensive.

48.164 | foundation vs columns | JETSAM::COURTRIGHT | | Mon May 09 1988 23:37 | 5 |
| The difference between a foundation and your column design is
probably the studding and finish siding to hide the columns.
Then there are the blocks or footings to 1 foot above grade.
Flat roofs are very expensive, when built not to leak. Seams
break, water collects and needs a place to go.

48.165 | addition on old house | KSYSI::KELLY | | Thu Sep 08 1988 11:25 | 19 |
|
We are considering putting an addition onto our 200 year old post
and beam house. Basically, the house is a cape with an ell off
the back. The ell is also post and beam and is currently one story.
We would like to make it two stories. The attic of the ell is
about six feet high, and the ell has settled quite a bit (probably
about six inches over 22 feet). Our question is should the
addition be built as a post and beam or can it be built using
modern framing techniques? I would like the effect of post and
beam since that is what we have in the rest of the house, however
the overriding concern is cost. The size of the addition would
be 15x22 and would consist of a second floor with a full dormer
off one side (22'long). What would the cost difference be between
post and beam and regular construction? We plan on only having the
framing and roofing done and finishing everything else ourselves.
How would the settling of the house affect the decision?

48.166 | | MTWAIN::WELLCOME | Steve Wellcome (Maynard) | Thu Sep 08 1988 17:26 | 16 |
| FIRST:
Find out what the cause of the settling is, and correct it, or
be ABSOLUTELY sure that
1. it's stopped
2. you won't EVER want to fix it later
If you don't have a secure foundation, anything you do on top of
it is living on borrowed time. I got part of my foundation replaced
this past spring (see recommendations under "General Contractors"
someplace (2007.*?)), and IF the guy knows what he's doing it's not that
big a deal, amazingly enough. Not cheap, but not as colossal a
project as one might suspect. There are some listings in the
Worcester yellow pages for people who do that kind of thing too,
who might be better than the guy I got.
You DO need to get somebody who specializes in it; most contractors
think about the house collapsing on top of them and panic, and don't
even want to look at it.
|
48.167 | no more settling | KSYSI::KELLY | | Fri Sep 09 1988 11:27 | 11 |
|
The foundation has been reinforced with concrete. It's a field
stone foundation and the reinforcement isn't very old. We are
(pretty) sure the settling occured before the reinforcement was
put in. There are also lally columns that support the floor joists.
Mostly our concern is how the settling will affect the ability to
build square on the second floor. We also really want to know about
whether to build post and beam or standard.

I don't see the post and beam vs. 2x construction as your main
monetary concern. I'd say your main concern should be the settling
which is close to 3/8" per foot, and which seems excessive to me.
Can you notice a difference in slope between the addition ell, and
the main building using a reference line? Seems that you'll have a
harder time getting things level, rather than square. I'm wondering
if you should consider jacking up the ell and getting some concrete
work done first, but I imagine this would raise hell with the inter-
ior.
Off hand, I'd say the difference in cost between materials is
not altogether that great, though the post and beam would be the
greater of the two, since you'd probably have to have the pieces
special made, unless a kit just happens to match the dimensions
that you are seeking to build. If you like the post and beam effect
than go that way and try to save money on other things that you
can do later.
I'd get a couple of contractors to come look at the job and
see what their opinion of the existing structure is, and what will
be required to add on the upper floor. My worry is that the added
weight of the second floor may be too much for the foundation, and
you will likely see more settling.

| Building a level second floor on top of a slanted first floor is not
necessarily a problem. You probably have to put in new floor joists
anyway, unless the ceiling joists above the existing room were made a lot
bigger than is necessary for ceiling joists. So the second floor can be
built level above an unlevel first floor ceiling. This was done in the
house that I now own, which had sagged in the middle. Obviously, you have
to decide that you never, ever want to straighten the first floor if you
do this.

the package out there, and they brought them in as we needed them,
using a forklift. This still left the logs at the top of the hill,
about 25 yards from the house. We, and friends, carted them down.
Towards the end of the project, we got smart and built a "chute"
out of plywood to send them down the hill.
As far as setting them in place, we just did it. The last few course,
we used a step stool made of log pieces, but basically, it was just
lift and place. We did this for 17 courses; the second floor is
framed, with log siding. I would think it would be more difficult
to do two stories of full logs, you'd need alot of staging and strong
friends.
Good luck.

If I understand you correctly, you must transport the logs some
distance over uneven terrain. If you have limited resources (read
people) to help, then I'd construct a dolly affair that would allow
you to strap a log in the middle between two large, sturdy garden
cart wheels. A large clamp or other such device, placed on one
end will allow the log/dolly contraption to be moved about. As
far as lifting them up without major mechanical means (forklift
etc.) you could use a Gin pole and a pulley arrangement. A ramp
and pulley arrangement would work well too.

| I own a log cabin made of 4*8 rectangular cut double T&G cedar logs.
If the wood is a softwood with lots of entrained air (like cedar),
there is enough thermal mass there that you don't need to worry
about insulation. The downside is that the house takes forever
to bring up to heat in Winter (I don't heat it between visits) since
it takes forever to heat up all that mass.
It always amazes me that the insides of a solid wall only 3-1/2"
thick are not cold when the temp outside is -10. The biggest problem
with conventional round logs it getting the cracks sealed.

48.179 | Labor intensive but doable | OASS::B_RAMSEY | Bruce Ramsey | Thu Feb 02 1989 19:32 | 32 |
| There is a show of PBS called The Woodwright Shop. The "MC" is
the master craftsman of Williamsburg and is connected to the North
Carolina University. He had a show about a year ago where he showed
how to get the logs up to them top.
They just placed logs at an angle from the top of the existing wall
to the ground. They laid a rope from the top of the wall to the
ground, wound the rope once around the log and then back up to the
top of the wall. People on the ground would push the log up and
people on the wall would pull on one end of the rope. The log would
roll up the incline and fall into place on the top of the wall. They
would then remove the rope and reset the angle logs to the new height.
Mother Earth News magazine has articles about building log cabins
every so often. You might check your local library to see if they
carry it and check with the research librarian for references into the
magazine.
As to moving the logs... The same show showed a cart affair used for
moving logs. They had 2 large wheels about 4 ft in diameter on an axial
about 18 inches/2 ft wide. It had 1 long beam that ran perpendicular
to the axial. The axial was placed about 1/3 along the beam. They
rolled the cart over the log, tipped the bean so the short end was down
and the long end was in the air. They tied the end of the log to the
short end of the bean and then used the long end as a lever and pulled
down on it forcing the short end and tied log into the air. They
continued to pull down on the long end until it touched the other end
of the log. They tied this end. The log dangles from the bottom of
the beam. At that point they had two guys, lift the long end and pull
the whole affair over and tied it to a horse. They mentioned that two
people could also provide the propulsion.

48.180 | Read a book | OASS::B_RAMSEY | Bruce Ramsey | Thu Feb 02 1989 19:48 | 13 |
| There is a series of books called FOXFIRE. The first in the series
of nine, explains how to build a log cabin/structure. It describes
how to cut the notches at the end, how to peg the logs, how to layout
the floor plan, how to build the mud and stick chinney, out to build
the foundation, how to build the tools to build the structure, etc.
Very detailed with many pictures and good explantaions. The book
was written as a college student special project by interviewing
old timers in the North Georgia mountains. More than 400 different
log cabins were examined and documented the differences in technique.
The series is very entertaining and should be available in local
book stores.

| This might sound extreme, but if that hill is bad, and you have
some large trees lined up well enoung, borrow for the loggers.
Put a cable in from beyond the unloading area to beyond the home
site, then a chain fall on a pulley will not only get the logs down
the hill but allow you to put them close to in place. Plenty of
of rope and one or two safty people should do the job.

48.9 | Man vs. Machine | OASS::RAMSEY_B | Put the wet stuff on the red stuff | Mon Feb 05 1990 17:36 | 11 |
| It seems that if you could dig a hole about 6 ft wide and to the depth
of the intended finished basement, you could knock a hole in the
foundation, after providing needed support, and drive a Bobcat in. Let
the Bobcat do all the digging and hauling. As pointed out earlier, at
the point of each support, provide temporary support, dig out the old
support, place a correctly sized longer support in, remove temporary
support and then continue to dig around the new support with the
Bobcat. Still a lot of work but let the machine do most of the grunt
work and you do a lot of riding around.
My other question is, what do you do with all the dirt you remove?

| I'm doing a similar double-the-house addition. As you will read in
other notes, you can't do plumbing but you can do electrical work on
your own house, usually, in Mass. I think the theory is that if you
foul up the electrical, you just burn your house down. If you foul up
the plumbing, you could contaminate other's supply water. (It follows
that if you have your own well, you should be able to do your own
plumbing... but it ain't so.)
I had an 'architectural designer' (someone who is not a certified
Architect) draw up plans that the building inspector was happy with and
subcontractors could use. If Groton, Mass. is convienent, ask me for
her name. Cost was about $2500 and well worth it! - Chris

48.186 | Starting an addition: basic questions | TOOK::FRAMPTON | Carol Frampton, DECnet/OSI for OSF | Wed Apr 21 1993 23:30 | 31 |
|
We're thinking of adding an addition onto our house, but we don't know
the best way to begin. We have a general idea what kind of addition we
would like but not specific enough to solicit bids without first having
plans drawn up, or at least talking to an architect or designer to find
out what is feasible and for approximately what cost.
Could someone who has been in this same position comment on how
we can get our questions about design and cost answered without
committing ourselves to using a particular architect or builder yet?
If the cost is out of reach, we may not do this project at all.
More specifically, we're considering expanding our basement as part of
this addition. How about an estimate on the foundation part of this
job which involves:
Excavating 12x16 foot area adjacent to the existing house,
deep enough for a full basement, plus excavating enough
to make space to reattach a pre-fab bulkhead to the new
foundation wall.
Remove the existing bulkhead, which is within the area that
is being excavated.
Pour foundation and floor for the new area.
Attach the bulkhead to new foundation and backfill it in place.
Thanks for any input.

48.187 | suggestions and estimates | VIRTUE::TRUMPLER | Help prevent truth decay. | Thu Apr 22 1993 18:28 | 19 |
| If you have a general idea of what you want in the addition,
you should be able to interview architects. You may get some
insights into design possibilities just by interviewing them
(and seeing pictures of, or driving by, their work). If you
want a recommendation (and live in eastern MA), send mail.
For construction costs, talk to contractors (again, no obligation,
just get estimates). The foundation for our addition (20x23),
crawlspace (not full), no bulkhead, was, hmm, 10-15K.
(The payment involved a few other things, so I can't break out
the exact cost. My guess is the low half of that range.)
Included excavation and backfill.
My back-of-the-envelope calculation says the addition portion of
our work comes to around $60/foot, plaster (no finish except doors).
(This assumes I've correctly divided the costs between the addition
and other parts of the job.)

| I just built an addition, but did sub out the excavating/backfill and
foundation work. It's 20 x 24' and has a full basement (8' celings)
with a poured bulkhead (vs. prefab). I poured the floor myself. Total
cost was right around $7000. The foundation guy also has a reputation
of being the best around the Maynard/Acton/Concord area. It definitely
pays to shop around for excavators. Those that own their equipment
outright generally charge less than those carrying heavy loans.
Although I had planned from day one to build this myself, I still had a
half dozen contractors come over to give us a price. Not only did I
want to see how much money we were saving, but they are also a good
source for ideas. As you might expect, prices can vary WIDELY.

My husband is an excavator and the excavation for your
addition should only run $2000. That is JUST for excavation..
He also said if your in Mass it would probably be cheaper
up there... (were in northern NJ)
I know 2 people who added second floors to their homes and
in each case in this area it ran 50-60K...

| If you hire an architect it will cost you more because (1) the
architect is likely to suggest/specify some goodies that cost more
that "standard" constrution, plus (2) the architect has to add
his/her fee to the cost.
What you've described doesn't sound too complicated. I'd suggest
talking to various builders. It seems likely to me that they'll be
able to provide plans at lot less expensively than an architect.
We went this route for our garrage/breezway addition (24' x 24'
garrage, 9' x 16' breezway connecting to house) and also for our
"3-season porch" addition (12' x 16' room plus DIY 14' x 16'
deck).
On the other hand, if you want something unique and are willing to
pay the cost required, then an architect is the way to go.

48.191 | some things that helped my addition | BRANDX::SULLIVAN | brake for moose. it could save your life. | Tue Apr 27 1993 15:33 | 23 |
| when i did my addition (started labor day 1990, almost done), i did the
following:
1-looked at a lot of magazines for ideas.
2-made up my own drawings.
3-found an architect through this conference to draw up plans.
4-got bids.
I have 2 books on construction planning and estimating. I found these to be
helpful for determining costs, but not as good as getting estimates. If you
send me mail, i'll look up the titles. if you ever come down to mlo, i can let
you look at the books.
i expanded my basement as well. it was 16x24, with bulkhead built in. As I
recall, it cost about $4500 - $4700. It was handled by Ashland Construction,
excavation, forms, floor, bulkhead, and backfill. They also dug and poured
footings for my deck and screened porch.
Please note. My foundation is only 4 feet, since the house is a split entry.
This is probably why mine was less expensive than the previous replies.

48.192 | My input | FSOA::PRINDLE | Send Lawyers, Guns, Money, and SOFTWARE | Wed Apr 28 1993 10:42 | 15 |
| I strongly suggest speaking with the building inspector first. I am in
the process of having an in-law apartment added to my house. I had to
get a variance to have it done. I also have a brook running through my
back yard and we are building within the 100 foot buffer zone. More
red tape. I don't know what your setup is but make sure you check out
the possible building code/zoning problems.
I also suggest having a DETAILED set of plans. Anything left for
interruptation could cause problems in the long run. Those plans act
as your contract. If your builder can't build to those specifications
then he has a problem.

I did my own in about 1/2 day. I took out the old wooden one, poured
a new form (raised about 4 inches as it used to be ground level, and
sloped the new form from 4" to 1"), installed new bulkhead putting new
anchors in the wet concrete and bolting onto sill. I went for the
BILCO which I liked better compared to the others (it is heavy too).
They provide good instructions, you just need to make sure you
measure properly (they have a guide before you buy). Its been great.
If you don't pour new concrete I think you can use other attachment
methods. I also caulked it as well.
Good luck.

This means I'll need two 15' walls and one 30' wall. Now, my question
has to do with the floor. I want part of it to be the same height as
the existing house, with the other part "sunken" about 7". I want the
foundation to match the existing foundation completely, though. Here's
a crude drawing of what I want:

| RE .11
OK, I'LL Bite. Why a 24" thick foundation walls?
Is't that a little over designed?
Just kidding ;>) !
I'll assume this is timerframe construction with building materials you called
out. If it is, consider stress skin panel to close in the frame. What do the
4x6 joist tie into? Typically, something this large would be notched into a
~6X8 header with a self locking dovetail. This would make a stepped foundation
the most reasonable option. Standard 2x10 or 2x12 construction would be
acceptable for the foundation cap and then build with timers on top of that.
The only one's to know when it's complete will be you and the critters living
under there. Not knowing the lay of the land, or your mechanical requirements,
a cheaper solution would be a slab foundation,just be sure to insulate well at
the perimeter. If you must have foudation continuous height, one way would be
a block wall with joist pockets 2 ft on center (8" increaments just work well
with blocks). Be sure to have your inspectors approval on how to keep the
joist from getting end rot. You need to keep them from getting and staying wet,
sitting in the pocket. You'd need to use solid blocks of fill the cores below
each pocket. I'd use 12" block for the stepped foundation and a combination
of 8" for the pocket and 4" to block off the end on the final course.

What ever you do, draw up cross sections down to the last detail. They should
start at the footing and go at least up to the wood frame interface and
include every detail. Here's a quick list of items to be called out in the
drawing: footing,foundation,drainage,foundation insulation,vapor barrier,
frame anchors, framing details,flashing, and the complete wall system. You
need one for each elevation change in the foundation. Good planning leaves no
hidden surprises as the project progresses. Also give consideration to
electrical and plumbing needs.
My intention is not to discourage you but expose you to some of the
options available and stress the need for careful planning. Doing your
homework pays off with big dividends of $$ and self satisfaction.
Give a little more background on the project. Like how does the lower
new finish floor ties back into the existing finished floor height at the
archway? How much or the work are you planning to do yourself?

We are thinking of making an offer on a 50 year old home. The
only hold back we have is there is only one exit/entrance
into the cellar which is from the kitchen. Currently they
have an office and a laundry room down there. We would like
to add an additional bedroom for our teenage son. How difficult
would it be to install a bulkhead type of exit so there would
be two regresses. If this is feasible how much of an expense
would this be. Any help will be appreciated. There's a window
located now where we would like the bulkhead and the ground
level comes just below the window.
Thanks,
Cyndi

| I think you meant "egresses" (as in PT Barnum's "This way to the egress!")
It's not at all "difficult", unless access to the outside area where the
opening is to be installed is difficult. The steps involved are:
1. Dig out area for entryway.
2. Cut through foundation wall.
3. Install new entryway box (precast, poured, cinderblock)
4. Install bulkhead and interior doors (and stairs if not included
in entryway box).
Cutting through the foundation wall is typically done with a special
diamond-edged concrete saw and may be a significant part of the expense.
I would expect this project to come in at around $2500-$4000, depending on
the size of the entryway and the particular materials you choose to use.
I recently had some of this done - I had an old bulkhead (metal) which was
to be ripped out and a new poured box put in (I wanted a very large one,
and since I wanted it to be "open" (so I could drop a spa down) I couldn't
use a precast box. The foundation opening was enlarged a foot. I supplied
the doors - the labor and materials for removing the old bulkhead and
putting in the new "box" was $2650. An interior door was $200 and the
Bilco bulkhead door was $300 or so (I got a big one with an extension).
(Don't skimp on the bulkhead door - quality matters here. Bilco is the only
brand I've seen which I would choose to own, and it isn't much more expensive
than the others.)
The cheapest way to go is a precast entry box which can be lowered by
crane/backhoe/whatever. Digging out with a backhoe is also the cheapest
method overall.
The cruical step is sealing the new entryway against water. The precast
boxes have a rubber gasket which goes against the foundation wall.

| I just put a bulkhead on the back of my house. The totals were as
follows:
o $180 to make the forms and pour a slab. Did it myself and
and had Brox concrete deliver the cement.
o $150 in materials for a cinderblock areaway.
o $225 for labor to pay some dude to lay the block for me.
I'm not gonna give his name because he gave me an excellent
deal and I know he doesn't want to do it again. The typical
cost to lay the block would be around $450-$500.
o $207 for the bulkhead door (Bilco) + $9 in caulk.
o Dunno how much the wood for the stairs will cost me 'cause
I'm still waiting for the block to dry and I'm in no hurry
to get them up.
Because of the location of my bulkhead, I couldn't have a precast
one put in. I called around for the prices on them, though.
It seems as though they run $750 - $1200 delivered/installed plus
a few hundred more for the delivering/installing the doors. I think
this price was if you did your own excavation.
I don't know how much it would cost to cut the foundation wall.
I did it with my dad once with a 1/2" masonry bit and a hammer drill,
though (it took forever), so it is something you can do yourself.

For 8" thick concrete the price was $22 a linear foot or $350 minimum.

Thanks so much for the great response. I am having a

my plans are doable. Then we will get as much help as
we need to do as much as possible ourselves. I really think
it would be hard to get a backhoe or any other large equipment

If all goes well we will make an offer on the house

Glad I found this note. I think we're gonna need it.
This will be our First home.
Thanks,
Cyndi
