Estimating the Cost for a Foundation and Footing • The Foundation • The Footing • Calculate and Convert • Vertical Rebar • Horizontal Rebar • Total Cost
The Foundation Base = 900 ft2 (36 x 25 ft) Calculate the required concrete and reinforcing rod
The Foundation Foundation 8in. thick 8ft high Volume of foundation = 8in. x 8ft x 122ft (perimeter)
The Footing Footing 8in. thick 16in. wide Volume of footing = 8in. x 16in. x 122ft (perimeter)
Calculate and Convert Calculate Foundation Footing 759.0 ft3 Convert Order 28.5 yards3 for foundation system
A 10 ft long rebar piece is vertically placed every 3 ft How many 10 ft pieces are needed for a 122 ft perimeter? 41 pieces Vertical Rebar
Horizontal Rebar Two rows of horizontal rebar are needed for the foundation and two for the footing. 6in. of each 10ft section of rebar is overlapped. Therefore assume a 9.5 ft length. Determine the number of pieces needed at 9.5ft. How many 10 ft pieces are needed for 4 rows with a 122 ft perimeter? 52 pieces
Total Cost Concrete Cost 28.5 yards3 x $98/yard3 = $2,793.00 Rebar Cost 93 pieces x $4.75 = $441.75 Total Cost $2793.00 + $441.75 = $3,234.75 Note: This does not include labor, excavation, gravel, forming material, etc.
