Berth 13 Structural Repairs, Portsmouth Naval Shipyard, Kittery ME (Solicitation # N4008526R0016)

This project provides structural repairs to Berth 13 to restore deck loading capacity and extend usable life of structure, repair deteriorated deck sections, and repair piles, caps, beams, deck, and steel reaction frame connections to allow continued use of the berth. Berth 13 is an open wharf structure waterfront facility constructed in the 1940’s consisting of concrete piles including previous jacket repairs, concrete wharf deck, and steel reaction frame with timber decking along the outboard face of the wharf structure. Total approximate construction area is approximately 25,000 SF. Berth 13 repair work will include both full (~1,600 SF) and partial demolition (area to be determined) to various portions of the concrete wharf deck; outage coordination, removal and replacement of utilities in the way of concrete repairs; repairs to the reaction frame; repairs to the landside fascia beam; and repairs to crane rail beams, pile caps, pile jackets and anodes. All demolition and construction activities must prevent debris from entering the river below. Underside wharf deck, pile jacket and anode repairs require the capability to work from barges and other floating platforms; as well as meet strict safety protocols.

P1112 B72 Resiliency Project provides a desalination facility with a non-potable process water net production capacity of 400,000 gallons per day, expected average daily need ranging between 250,000 to 300,000 gallons per day. The project provides pumping and control systems to pump the produced water to existing condensate receiver tank (base bid) and pumped and interconnected with existing south and north cooling towers piping. The project provides an underwater seawater intake at the face of existing Berth 5 consisting of an EPA 316B compliant intake screen with integrated automated airburst self-cleaning system, intake pumps, and piping. The project provides a desalination process consisting of an ultrafiltration pre-treatment inclusive of break tank and blowers; seawater reverse osmosis (SWRO – Stage 1); brackish water reverse osmosis (BWRO – Stage 2); 30,000 gallon permeate storage tank; and a chemical clean in place system consisting of several chemical storage tanks. The project provides a submerged brine discharge/outfall at the face of existing Berth 4. The project provides coordinated localized repairs, renovations, and structural changes to Building 242 and historic masonry Building 72. The scope in Building 72 includes abatement of hazardous building materials as well as limited restoration of masonry. The scope in Buildings 242 and 72 involve structural reconfiguration of existing structural concrete deep gravity seawater wells. The project provides extension of existing 13,200V electrical, inside compressed air, inside domestic water, and sanitary sewer utility systems. The project includes bid options to provide controlled density fill within existing original 100 year plus old gravity seawater tunnels. The project scope includes all necessary local instrumentation and controls for all new installed systems and includes integration within existing B72 boiler plant controls. The project excavations involve some isolated areas of excavation within known hazardous soils.

Project consists of structural upgrades and repairs and upgrading life safety, egress, and accessibility components in the building to meet current code requirements. The project includes providing an elevator, adding building wide sprinkler system, and fire alarm system. Hazardous materials abatement, structural replacement/repairs, power distribution and system upgrades, building envelope repairs, interior space renovations, utility upgrades, and incidental related work. Phasing and coordination with shipyard operations is paramount and mission critical elements need to remain fully operational throughout the duration of the project. Building 60 is an historic facility and requires special coordination to have limited impact on the historic fabric and character defining features of the structure.
