PERFORMANCE WORK STATEMENT

For

Electrical Distribution Maintenance February 17, 2026

Objective

To service, maintain, test, troubleshoot and make repairs as needed to switchgear and the downstream electrical distribution equipment as identified in the Stewart Lee Udall Building.

History

The Stewart Lee Udall Building, the Department of the Interior (DOI) headquarters, was originally built in 1936 and concluded a multiyear/multi-phased modernization project in 2017. The building is under the jurisdiction of the General Services Administration (GSA) with delegated authority to DOI for operation, maintenance, repair, and alteration of the facility. The delegation includes the authority to operate, maintain, and repair the electrical distribution system for the building.

The building consists of 10 floors, basement level through floor 7 with a mezzanine between floor 5 & 6 and a penthouse above the 7th floor. The building receives service from four (4) Pepco 13.8 KV distribution feeders which come into a main incoming electrical vault room. Voltage is transformed from 13.8 KV to either 4160 V, 2400 V, 2300 V, 277Y/480V, and/or 120Y/208V. Electrical switchgear manages the flow of electricity to the building, ensuring safe and reliable power distribution, and acts as a central control point to isolate and protect downstream electrical equipment.

Location Work shall be performed at:

The Stewart Lee Udall Building 1849 C St NW Washington, DC 20240
