I have a question for anyone who is involved with building ICF houses in Southern Ontario. What is a ballpark for cost/sq foot to have an simple ICF house built?  The house would be a simple rectangular single-story bungalow with full basement, and ICF from basement to roof. Say 1100 sq. ft main floor.

Ballpark - $ 12-19.00 per sq.ft. of ICF wall

Really need to see plans to get it more accurate and depending on what you want, i.e. who's doing the footings? waterproofing? weeping tile and gravel? core size of block?

Thanks for this. I would suppose that the ICF builder would be responsible for all those things you mentioned. Therefore would the cost be in the upper end of the range you mentioned?

The cost of the ICF per square footage is totally apart from the costs of the footings, foundation, etc.

For the ICF forms (6"), concrete, rebar, all the labor to stack, place the rebar, pour the concrete, etc., you are looking at $11 - $17 per square foot of wall space, including windows. So let's say you have a total of 3,500 square feet of wall space on the home, you would be at $38,500 - $$59,500. Most likely it will be somewhere in the middle $13-$14. Unless you have curved walls and complicated aspects to the build, it should be around the $13 range.

If you get quoted anything above $15 sq. foot, WALK AWAY. Either find another contractor or build it out of wood frame.

Being in Canada, add $3/ft2 to that $15

If your project is a simple rectangle, why not pour your footings and walls at the same time. http://fab-form.com/fastfootMp/fastfootMpOverview.php

This will save about $1500 on the associated costs involved in pouring your footings, and then your walls a week later.

Lbear...I'm working on one right now with 6 radius walls...come on up...I got some work I want to sub out to you!!

Joe is right, you can save money, generally the cost of one pump trip doing the walls and footings as one pour, however...it's not for the light at heart to do.

Being that you are up in Canada, what are you charging per foot for the walls?

The price is based on the job

it ranges from 12-19/ft and sometimes as high as 25 depending on the layout of the job, local concrete rates, pump rates, bar, what accessories are needed etc. Without a plan I can not give an accurate price

That's a pretty large range. I know Canadian prices are always a little higher than American rates but is that range for all of Canada or just a certain Providence?

I'm sure the price is all over, I'm in Toronto and probably have the cheapest concrete prices out there, even by US standards. The further away you get and the further north you get it's 2-3 times what I pay! Steel is another factor that seems to be price decided by area and block itself is pretty consistent everywhere.

Rebar is cheap, But concrete is not. I paid 10000 for concrete at footings and basement walls (12 feet). mine is 1400 sqf.
