This 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.
New!
BuildBlock Bid System
(Microsoft Excel based)
Our new Bid System is more complex and detailed
than the Project Estimating Tool. It allows you to enter your own
costs and print out a customer-ready Bid Sheet.
Follow the instructions below to estimate how many BuildBlock
forms you'll need for your construction project.
Divide
wall height by 16” and round up. This is the
number of courses required.
Multiply
the # of 90° corners in the structure by the # of courses
required. This is the
number of 90° corner forms
required.
Multiply
the # of 45°
corners in the structure by the # of courses required. This is
the
number of 45° corner forms
required.
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.
Determine
the
total square foot area of wall being formed
(width 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.
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.
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.)
