You have been asked to quantify the reinforced concrete & formwork required to build the foundations of a 21-story skyscraper, covering a footprint of 100 ft x 250 ft. The foundations consist of 15 footings each of which is 2' in length, 2' in width, and 12" deep. Additionally, a foundation wall that is 8" thick and 2' tall will be placed continuously on each pad, along the perimeter of the building. No. 6 rebar will be placed vertically, within the foundation wall, 48 inches on center. Finally, 4 No. 4 rebars will be placed into each footing NOTE that No. 4 rebar is 0.668 lbs/ft & No. 6 rebar is 1.502 lbs/ft
