Estimate the total cost of reinforcing steel for a concrete slab on grade. The slab will be 80 ft long, 120 ft wide, and 6 in. thick. The reinforcing steel will be No. 4 bars (1/2 in. dia.) spaced not more than 12 in. apart each way in the slab. Add 60 bar diameter as the lap of splices for both sides. The bars laid next to and parallel to the edges of the slab will be placed 3-in. from the edges of the slab. The ends of the bars will extend to within 2 in. from the edges of the slab. Skilled steel setters will be used at a cost of $29.00/hr. Labor hours to install steel are estimated at 14 hours per Ton. The weight of no.4 bars is 0.668 lb/ft. The cost of reinforcing steel delivered to the job will be $0.46/lb. List each step of the calculation. Estimate the total cost of reinforcing steel for a concrete slab on grade.
