The basic costs (labor, material and equipment) for various elements of a construction project are given as follows:
Excavation $240,000
Subgrade $100,000
Base course $420,000
Concrete pavement $640,000
Total $1,400,000
Assuming that field supervision cost is 10% of the basic cost, and the general office overhead is 5% of the direct costs (sum of the basic costs and field supervision cost), find the prorated field supervision costs, general office overhead costs and total costs for the various elements of the project.
