Project Details

Building 2 Renovation, National Institutes of Health, Bethesda, Maryland
As the prime designer, WFT Engineering provided detailed systems analysis to determine the most life cycle cost effective mechanical, plumbing, electrical, and life safety systems for this 52,000 sf historic building. The HVAC system included the installation of a variable flow tertiary chilled water system, steam to hot water converters, and variable flow pumping systems. The airside systems included a custom built central station, M&I variable flow air handling unit, and VAV terminals with terminal reheat. The air handling unit was carefully designed to fit in an existing building and meet all outside air codes and standards. The electrical study and design included the analysis of the existing system, short circuit calculation, over current protection coordination, the specification of network transformers, network protectors, double-ended switchgear, feeder bus duct distribution panels and conductors. The project also included the installation of telephone and LAN wireways, spot network transformers, and double ended air-draw-out switchgear, which were all in accordance with The NIH Design Policy Guidelines.
