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 ft 2 (36 x 25 ft) Calculate the required concrete and reinforcing rod

Foundation 8in. thick 8ft high Volume of foundation = 8in. x 8ft x 122ft (perimeter) The Foundation

Footing 8in. thick 16in. wide Volume of footing = 8in. x 16in. x 122ft (perimeter) The Footing

Calculate and Convert Calculate Foundation Footing ft 3 Convert Order 28.5 yards 3 for foundation system

Vertical Rebar 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

Horizontal Rebar 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? Two rows of horizontal rebar are needed for the foundation and two for the footing. 52 pieces

Total Cost Concrete Cost 28.5 yards 3 x $98/yard 3 =$2, Rebar Cost 93 pieces x $4.75 =$ Total Cost $ $ = $3, Note: This does not include labor, excavation, gravel, forming material, etc.
