P1112 B72 Resiliency Improvements, Portsmouth Naval Shipyard (PNSY), Kittery, Maine

The project involves the construction of a desalination facility within the Portsmouth Naval Shipyard, specifically in Buildings 72 and 242. The facility will employ a multi-step treatment process to provide feed water for boiler and cooling water in Building 72. The major components of the project include a new intake at Building 242, a new desalination intake pump station, a new piping system connecting Buildings 242 and 72, and a new desalination facility primarily located within the Pump Room S in Building 72. The project also involves the partial or complete abandonment of the Saltwater Tunnel, as well as the installation of new electrical and process control equipment. The work must be completed while the buildings are occupied, and the contractor must ensure that the existing furniture and equipment are protected from dust, debris, demolition, and construction activities. • The project requires the construction of a new intake at Building 242 and a new desalination intake pump station. • The project involves the installation of a new piping system connecting Buildings 242 and 72. • The project requires the construction of a new desalination facility primarily located within the Pump Room S in Building 72. • The project involves the partial or complete abandonment of the Saltwater Tunnel. • The project requires the installation of new electrical and process control equipment.
