We are trying to create a budget for our new 4 season sun room and need to know what it would cost to dig a 17 x 17 foot, 8 feet deep basement with footings and block walls. We have the permits already.
Looking for cost only.
Thanks.
It depends on thickness of wall, do you need draintile, do you need it backfilled, will the wall need damp proofing membrane, and do you need the slab poured as well?

Joseph,
It will depend on where you are, the type of soil (sand, rock, mixed, etc.), and if you want it hauled away. For a good sized excavator, it would take a day but if trucking is involved, expect a significant difference. I'm not sure of the rate in Ontario but ball park should be in the range of 3 -$5,000. Hope this gives you a basis to plan a budget.
Also, as John mentioned, the type of foundation makes a difference. There is concrete, ICS (Integrated concrete System) {which is concrete between styrofoam - like a sandwich}, pressure treated wood, ... all having pros and cons. I prefer the ICS as it provides an insulating factor and make a lot of sense. (look into it).
Back to you excavation, I'd suggest calling about three local excavators (once you decide about hauling away or not) and ask for estimates based on your measurements. I might also suggest the you increase your measurements if your finished size is to be 17 x 17 x 8 because you'll need room the forms and backfill.
