Design-Bid-Build Waterfront Emergency Generators
Client: US Navy
- New construction of a ballistically hardened emergency generator building to minimize risks associated with natural disaster, blasts/ballistic attack, CBRN, EMP/HEMP
- Weapons movement: During the movement of weapons the CMS crew was not allowed to be outdoors at the project site; CMS scheduled work around this factor so that work performed indoors would be performed during extended periods set aside for weapons movement
Role in US National Defense
The new facility is an enclosed cast-in-place and precast concrete building with an EIFS finish. The main portion of the building is two stories with a one-story section having a walled-in area and the other side of the building having a removable wall in the event the generators would ever need to be removed/replaced. The ballistic screen wall is constructed of concrete masonry units with a concrete wall cap and ballistically rated mechanical gates. The main two-story section houses the two generators, while the smaller one-story section is the control room, housing the switchgear. It includes a bathroom. Interior finishes for the generator room includes painting concrete walls and ceilings, and sealing the concrete floor. The control room and bathroom are painted drywall with VCT flooring.
The site for the facility is raised approximately 7′ with structural fill, and the building foundations are spread footer style reinforced concrete over prepared subgrade. The screen wall foundations are CMU. The floors are concrete slab-on-grade, with the generator room having a built-in trench drain running around the raised generator pads.
The finished grade in the outside mechanical yard is aggregate base. New underground utility services include water, sanitary sewer with force main and lift station, fire supply water line and electrical and communications lines.
