New & Improved! BuildBlock Project Estimating Tool (Microsoft Excel based)

This NEW estimating tool allows you to figure the BuildBlock forms, rebar, concrete, and other accessories that may be needed in your projects. This program is used for estimating purposes only and may require rounding on final orders. It is designed to be very simple and expedient in estimating most ICF projects.

Manual Estimating Method:

1. Divide wall height by 16” and round up. This is the number of courses required.
    
2. Multiply the # of 90° corners in the structure by the # of courses required. This is the number of 90° corner forms required.
    
3. Multiply the # of 45° corners in the structure by the # of courses required. This is the number of 45° corner forms required.
    
4. Use the chart below to determine the total square footage of all 90° forms to be used.  (Number of 90° forms multiplied by sq. ft. per form.) Do the same for the 45° forms.
    
5. Determine the total square foot area of wall being formed (linear footage of structure x height, minus 80% of window and door openings). Subtract total square foot of all 90° forms to be used and all 45° forms to be used.
    
6. Divide the remaining square footage of the wall by 5.33 to determine the number of straight forms required. Add a small number of forms for possible waste.
    
7. Estimate the concrete volume required by the following: Divide total square footage of wall to be formed, including corners, by 53 or 40 (for 6” or  8” forms, respectively). This equals the number of cubic yards of concrete required. Add 1.5 additional yardage for waste and the pump. (You do not want to be short on concrete. Delays are too expensive on manpower and pump costs.)
