This document is Amendment 0003 for the Chickamauga Lock Approach Wall and Decommissioning contract (W912P525RA001), issued by the U.S. Army Corps of Engineers Nashville District. The amendment includes comprehensive updates to technical specifications across multiple sections, contract drawings, and contract line items. Key changes involve revisions to sections related to concrete materials, placement requirements, excavation, approach wall piers, and installation of government-furnished precast concrete beams. The price breakout schedule was updated with corrected quantities for steel setting piles and downstream approach wall pier guide pipe pile rock sockets for both base contract and optional work.

The amendment also modifies Federal Acquisition Regulation (FAR) clauses, removing several standard provisions and adding updated versions with class deviations. Significant changes include updating Annual Representations and Certifications, removing equal opportunity and affirmative action clauses, and revising provisions related to subcontracts and apprentices. Additionally, contract line items were adjusted, such as renaming the "Site and Existing Lock Light Pole Removal" item and adding a new line item for "Demolition of Remaining Existing Lock Features" with a quantity of one job.
