cost footing for a garage
Re: Garage Foundation Slab cost? I had a 24x40 built in Eastern Idaho last summer (2009), with virtually identical frost-wall/footing/slab requirements as you, and the total cost for the concrete contractor, including excavation and steel, was $7500. Mt footings are 8 thick and come up 18 above ground. am finishing off a 20X32 workshop attached to my garage. I didn't want to blow my budget on the foundation so I was looking at different methods of reducing costs. My estimate for 42 frost walls/footings/slab was about $8000, not including excavation.
