Manson Construction dives into $89.4M submarine pier extension

ConDig (05-Feb-19)  Seattle, Washington-based Manson Construction Co has secured a $89.4 million design-build contract to extend a submarine berthing pier at the Naval Base Kitsap in Washington. 

Under the firm-fixed price contract with the US Navy, the company will build a 520 foot by 68-foot single level, reinforced concrete submarine berthing pier extension, along with pier-side utilities, communication systems and two-580-square-foot concrete floating camels.

The pier extension includes engineered pile and caps to support the pier deck, a fixed crane, equipment pads, mobile cranes and utility buildings. 

The project also configures and adds to the existing wave screen attenuation system and modifies the existing small craft berthing at the service pier. Additionally, it will feature a low-rise compressor building on the pier for new tool air compressors and breathing air compressors and alters an existing building to accommodate new and existing lift stations, sewage equipment, storm drainage, industrial wastewater services and provides a new emergency generator. 

Work on the project in Silverdale, Washington, is earmarked for completion by July 2022.

The contract was competitively procured through the Federal Business Opportunities system and five offers were received, the US Navy reported.
