Y--NRL 74/81, DBB, Solid State ElectronicDevices Laboratory, Naval Research Laboratory Washington, DC

Design Bid Build construction, firm fixed-price, contract for the NRL 74/81 Electronic Science and Technology Laboratory, Naval Research Laboratory: Solid State Electronic Device Laboratory. The project consists of repair of the Solid State Electronic Device Laboratory, building 74/81 (single building), located at the Naval Research Laboratory Installation in Washington, DC. The building will be used for clean room laboratories associated with electronic devices and sensitive research. The building is currently 19,579 gross square feet and is unoccupied. The total expansion consists of 10,772 gsf of new floor area. Construction and modifications to the existing building will increase the gsf to 30,301 GSF. The repair will consist of selective demolition, renovation, restoration and new construction within the existing building. Demolition work includes the removal of the 24” thick concrete slab, below grade utilities such as, but not limited to sanitary piping, water lines and electrical conduits, mechanical, electrical, plumbing and architectural components. Renovation of the existing first floor area will contain 19,579 gross square feet. The renovation includes replacement and repair of structural and architectural systems including steel framing, second floor assembly, roof, windows, doors, exterior finishes, exterior egress stairs, elevator, partitions, interior finished, laboratory facilities and abatement of hazardous materials. The new construction includes an addition containing an elevator and two stairways and a new second floor system containing 9,576 square feet and consisting of a steel frame with new concrete foundations. A new 24” thick concrete slab at the first floor is included in the project. Certain labs require vibration control components in the base building. A new roof will be installed. A portion of the first floor (1,500 sf) will require a new one story pre-engineered building approximately 24 feet high. The exterior of the pre-engineered building will be a pre-finished metal facade and roof system.
