I'm trying to get together a design for a 1 1/2 bay free standing garage
and I need a couple of questions either answered or directions on where
to go to get the answers (I've been told where to go on several occasions
but that place doesn't seem to have what I need now :)
The garage will be somewhere in the neighborhood of 20 foot wide by 24
foot deep with a 15 foot ceiling. The height is for a future car lift so
I can change oil and tires on my vehicles in my old age without bending
First things first, before I can really get into this I have to get a
working draft of the plan that I can submit to the local code thugs so I
can find out if where I want to put it will be allowed. Real pain in the
behind since if they wont let me put it where I need to put it then the
entire project will have to be scrapped. :( So needless to say I wont be
spending money on a 'bought' plan since there is a chance I'd never get
to use it.
So I'm starting out with the basics, the foundation, after digging around
a bit I'm kinda stumped as to what I need. So here are the questions.
1. How deep will I have to make the footer if our local frost line is 32
inches and my soil is very heavy clay. Do I have to make it like an
inverted 'T' or can I just go straight down.
2. This will be a framed building with plywood sheeting and siding on the
outside and sheetrock on the inside. How wide must I make the footer, 4,
6, 8, 10 inches???
3. My soil is a very heavy clay do I have to put drainage around the
bottom of the footer?
4. I want to dig and pour the footer first then later after the building
is up have the floor poured, mainly since I plan on doing all but the
slab myself I figured it could be the last thing I do budget wise and I
could even hold off if money was tight and still get use from the
building. Should I make a 'lip' on the inside of the footer and pour the
slab on over it or can I just pour it to butt up against the footer.
Sorry to be long but I'm kinda stuck here until I can get this figured
out. If I was out in the boonies like my Dad I'd just put up a pole barn
and be done with it but here in civilization I have to do better.
