LD3_UGW_Coring_Reference_Drawings.pdf

This document appears to be a set of reference drawings related to a federal contract opportunity. The federal contract opportunity is a solicitation (Solicitation Number: W912ES25Q0017) issued by the Department of the Army Corps of Engineers Engineering District St Paul for a concrete testing project. The contractor will investigate and evaluate the interior concrete condition of the upper guide walls at Lock and Dam (LD) sites 2 and 3. The contractor will vertically drill and extract eight 4-inch diameter cores at each site, conduct lab testing including petrographic analysis and compressive strength testing, and compile the results into a report to be submitted within 90 days of contract award. The reference drawings appear to provide details on the monoliths, traveling mooring bitts, sections, and extensions related to the upper guide walls at the LD sites.
