P197 Design/Build Decentralize Steam System, NSA Norfolk, VA

THIS PROCUREMENT IS RESTRICTED TO CONTRACTORS ON THE GENERAL MACC. The inclusive contract numbers are: N40085-09-D-5019, N40085-09-D-5020, N40085-09-D-5021, N40085-09-D-5022, N40085-09-D-5023, N40085-09-D-5026, N40085-09-D-5027, N40085-09-D-5033, and N40085-09-D-5034.





This project will eliminate central steam at Naval Support Activity (NSA) Norfolk and Lafayette River Annex (LRA). NSA, which includes the Camp Allen area, currently receives steam from Naval Station Norfolk's P1 power plant. LRA is sourced from two steam boilers located in Building H. High efficiency and high performance heating, ventilation, and air conditioning systems (HVAC) will be installed to replace the central steam systems in these areas.

These systems may include ground source heat pumps, natural gas (NG) steam boilers, infrared heaters, NG condensing hot water (HW)boilers, NG condensing domestic HW boilers, Turbocor retrofit on chillers, variable flow chillers, variable frequency drives (VAV) on chill water (CW) pump and HW/CW temperature reset by outside air. The specific types of systems to be used will be determined during the design process. The project will include electric metering, sub-metering (at lighting panels, power panels, and HVAC loads), building envelop upgrades, occupancy sensors, economizer, cool roof, chiller heat recovery and outside and exhaust air system with variable speed heat recovery. The project will include tests and balancing and fundamental and enhanced commissioning of the new system, Direct Digital Controls (DDC) and digital lighting management.

In addition, the project will demolish NH35. In its place, a new control building at NSA's main site to house the new DDC center and public works personnel. The DDC infrastructure and main control room equipment are included as part of this project. Other building features include administrative areas, shops areas, and an area for the new DDC system.
