Summary

Stops hiring private contractors for river and harbor work when the price is more than 25% higher than the Army’s estimate. The Secretary of the Army, through the Chief of Engineers, must block a private contract if government equipment and crews are available and the private price is over 25% higher than the estimated government cost. The Secretary must also block any contract that is more than 25% above a fair estimated cost for a well‑equipped private contractor. Cost estimates must include labor, materials, depreciation, supervision and overhead, interest on invested capital (not above the United States’ current bond rate), and other proper charges; private estimates also include workers’ compensation, liability insurance, and state and local taxes.
