Portsmouth Naval Shipyard P282

Addition to Building 170

Brunswick, Maine

This design-build project created a 43,000-sq.-ft. addition to the existing historically significant Building 170. The expansion and the inclusion of an automated material handling system and equipment consolidated functions that were being performed in several buildings, providing a safer working environment and greater efficiency of this service to the Navy’s fleet.

The addition included a state-of-the-art global submarine component facility that enhances the Navy’s ability to receive, inspect and distribute submarine components worldwide in support of the fleet. It serves as a receiving, storage and shipping facility for palletized submarine components as well as pipe and bar stock.

The expansion included a single-story, steel-framed addition with a concrete mat foundation, concrete slab floor, brick masonry, and metal panel clad exterior walls, loading dock doors with dock seals, bumpers, and levelers, a low-sloped standing seam metal roofing system, fire protection system, heating, ventilation, power, data, and communication systems. Sustainable design was integrated into the design, development, and construction of the project.

This project achieved LEED Gold certification.
