Facility 20145 requires construction services for a Design-Bid-Build reconfiguration of an existing high-bay space by constructing new endo-skeleton structure within an existing facility and renovating existing space to create secure laboratory space. The project includes construction of 4 floors at the high-bay area in facility 20145 by providing three additional separate elevated floors (Total 17,941 SF) above the existing basement floor. These spaces will create additional secure laboratory space within the building envelope of the high bay existing footprint. Additionally, a renovation shall include 9,666 SF of existing space. Space will include modeling, simulation and analysis (MS and A) laboratories, control rooms, and Network Operations Center (NOC) rooms. Repairs include necessary work to supporting Mechanical, Electrical and Plumbing (MEP) systems and applicable communications. Project will comply with Intelligence Community Directive (ICD) 705 requirements, as well as standards established in UFC-3-410-01 (HVAC Systems), UFC 3-401-01 (Mechanical engineering), UFC 3-520-01 (Design, Interior Electric Systems), UFC 3-530-01 (Design, Interior and Exterior Lighting and Controls), NFPA 13 (Standard for the installation of sprinkler systems), NFPA 101 (Life Safety Code), NFPA 70 (National Electrical Code).
