This document provides details for a federal contract opportunity to construct additions to Dry Dock #1 at Portsmouth Naval Shipyard in Kittery, Maine. The project will construct two new bays, labeled Dry Dock #1 North and Dry Dock #1 West, of sufficient size and depth to support maintenance and overhaul of Virginia Class submarines, Blocks I-IV. New construction will include concrete floors, walls and a center wall separating the bays, new pump well systems and a pump station building, portal crane rails, mooring hardware, mechanical and electrical utilities, utility tunnels and all necessary appurtenances to ensure operational dry docks. Modifications will also be made to the existing basin closure wall and Berths 1 and 11 to prevent undermining and support fully dewatered conditions. The existing Dry Dock #1 pump well will be connected to the new system and interior modified. The solicitation was issued by the Department of the Navy Naval Facilities Engineering Command for a design-bid-build project.
