This document contains reference record drawings and details for the P653 Dry Dock Flood Protection Improvements project at the Norfolk Naval Shipyard in Portsmouth, Virginia. The project will construct a permanent flood wall to protect Dry Docks 1, 2, 3, and 4 from flooding from the Elizabeth River. A cast-in-place reinforced concrete wall will be built on a shallow foundation supported by soil treated with subsurface grout injection. The project will also modify existing Dry Docks 1 and 3 caisson gunwales, construct caisson seat extensions for Dry Docks 1, 2, and 3, and remove existing capstans and construct removable capstans on new foundations. The solicitation was issued by the Naval Facilities Engineering Command for design-bid-build services.
