NAVFAC D/B NRL 35 Replace Secondary Unit Substation T-54, Washington, DC – $2.5M

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.
