W911WN25BA013 Amendment 0001.pdf

This document is an Amendment of Solicitation/Modification of Contract for the Conemaugh River Lake Accumulated Sediment Dredging Project (Solicitation Number W911WN25BA013). The amendment extends the period for questions to be entered into ProjNet to 13 June 2025 and revises several contract drawings and technical specification sections related to environmental controls, archaeological and historical resources, and environmentally sensitive areas.

Key changes include revisions to multiple contract drawing sheets (G-002, G-101, G-102, C-302, C-502) to add reference triangles, update map legends, and include notes about environmentally sensitive areas and archaeological buffer zones. Technical specification changes involve modifying sections on temporary environmental controls, specifically adding requirements for archaeological and historical resources, renaming the archaeological buffer zone, and including additional notes for environmentally sensitive areas. The amendment maintains the original project scope of dredging accumulated sediments in Conemaugh River Lake, constructing a Dredged Material Management Area, and completing associated site restoration work within 685 calendar days.
