Doyon Management Services will be working with NAVFAC Washington on this 670 calendar day Design-Build project to remove the exiting 750KVA Multi-tap Secondary Unit Substation T-54 and associated 15kv interrupter switches, medium voltage and low voltage transformers located between NRL Buildings 54 and 35. Doyon will also replace substation and associated equipment with a new 750KVA, 13.8KV/480 Secondary Unit Substation and associated 15kv interrupter switches, with dry type medium and low voltage transformers capable of producing 230V and 208V. We will cap the existing underground conduits in the duct bank and abandon the existing concrete support pad. The new switchboards shall contain 20% fully bussed space for future breakers. Lastly, we’ll remove the existing switch gear in the electrical room and replace it with a new one of the same kind.

Doyon Management Services will be working with the U.S. Space Force on this 90 calendar day project to convert the Aqueous Film Forming Foam (AFFF) fire suppression system to a wet pipe fire sprinkler system. Perform a fire flow test on the fire hydrant nearest to building 676 to obtain the data necessary to properly size the new wet pipe system into the facility. Work consists of demoing 4-inch foam proportioner, 4-inch Outside Steam and Yoke (OS&Y) control valve, 200-gallon AFFF concentrate tank and associated foam piping. Dispose of all AFFF contaminated components and piping in accordance with Environmental guidance. Design and install new fire suppression lines, check valves, isolation valves, system flow sensors, tamper switches and communication devices.
