The Eisenhower Executive Office Building (EEOB) is located on the West Campus of the White House, housing a majority of the offices for the White House staff.  As a National Historic Landmark, the building serves as one of America’s best examples of the French Second Empire style of architecture.  The EEOB has undergone a number of renovations in recent years, including a two-phase electrical system upgrade.  During phase I, Singleton’s scope of work consisted of a new utility plant; new power, data and security fit-out; and infrastructure to support this and future phases of construction.  The building remained occupied during the entire project, requiring Singleton to coordinate planned outages and service change out without disrupting the day-to-day activities of the tenants.

For the second phase, Singleton demolished the antiquated electrical distribution system and installed new 4000A 480V spot network switchgear and associated distribution, controls, and power monitoring. The team also provided and installed two 2500KW 480V emergency generators, automatic transfer switches and associated distribution and controls to back up critical loads, and nine UPS units for mission-critical power. Singleton designed and installed a custom under floor distribution system for tenant office space power and telecom. The project also included installation of telecom pathways, cabling, and IDF distribution, as well as replacement of the EEOB’s fire alarm system and security system, including access control, intrusion detection, emergency notification, and CCTV.

This project won the prestigious GSA Honor Award in 2014.
