To estimate the contract administration cost, use 6 to 10% of the operational and maintenance (O&M) cost. Calculate the contract administration cost as a <br />11. For Federal construction contracts, use 10% of estimated O&M cost for the contractor’s profit. <br />RECLAMATION COST ESTIMATION SUMMARY SHEET FOOTNOTES <br />1. Federal construction contracts require Davis-Bacon wage rates for contracts over $2,000. Wage rate estimates may include base pay, payroll loading, <br />10. Federal construction contracts exceeding $100,000 require both a performance and a payment bond (Miller Act, 40 USC 270et seq.).
