Can anyone give me a general formula for estimating the cost of ICF? Somewhere I saw $10/sq ft of wall space as a reasonable estimate when trying to decide which type of foundation to go with. That figure included the cost of the block, steel, concrete and labor as a general guideline. Does that sound reasonable? We are in California and I'm wondering if it may be more. Since our house plans aren't finished yet, we can't go after firm bids for it yet and I don't want to wastes time having the foundation drawings geared towards ICF if it's cost prohibitive. Your experience?
