Elevators in Building 9

This project involved modernizing two passenger traction elevators in two separate hoistways, for a total of four elevators in Building 9 at Walter Reed National Military Medical Center (WRNMMC) in Bethesda MD. The Scope of work included the demolition of elevator landings / lobbies and existing Fan Coil Units and the installation of mini split, HVAC units, in mechanical rooms to maintain cooling/heating levels for elevator controllers and equipment. This project also involved installation of two new sump pumps along with the required piping and associated set lines, ductwork modifications, and installation of fire and motorized dampers. In addition, new thermostats and control wiring were installed.

Upon completion these new elevators will support the hospital staff at WRNMMC.
