The consolidated East Coast headquarters of the National Geospatial-Intelligence Agency, NGA Campus East is the largest project delivered by the U.S. Army Corps of Engineers (USACE) since the Pentagon in 1943.

The project consists of a 2.2 million square-foot main office building to accommodate 8,5000 workers (as well as 25 percent population/mission growth), a technology center that includes a Tier III Enterprise data center, a 105,000 square-foot central utility plant, a 5,100-space parking garage, and a 7,300 square-foot visitor center.

An integral part of the National Geospatial-Intelligence Agency’s (NGA) New Campus East, the Technology Center is a 125,000 square-foot data center that will support all electrical components and house the NGA data communications storage facility for classified information.  The Technology Center’s electrical system is notable for its exceptional craftsmanship, massive size, and the challenges presented by exterior factors, including a compressed construction schedule, complex design, limited and congested work areas, and coordination with multiple trades.  The system components include 34.5 kilovolt, 480 volt, and low-voltage systems including multi-module and rotary UPS systems, and power distribution units, all connected by a large, complex network of power feeders and busway.

Located in the Ashburn Corporate Campus and designed to LEED standards, ACC6 is comprised of approximately 262,000 gross square feet with 130,000 raised square feet and 26.0 MW of critical load.

The facility is located in the Ashburn Corporate Center campus (ACC) in Northern Virginia and was constructed in two phases of 13.0 MW of Critical Load each; Phase 1 was delivered in September 2011, with Phase 2 delivered in December 2012.  With its flexible and efficient design, customers are able to lease one or multiple dedicated computer rooms each with independent redundancy and security.

Should a tenant’s requirement increase, our scalable solution enables them to take additional space as needed.  The facility is able to utilize the multiple major fiber providers currently on site and benefits from the area’s most competitive power rates.

The project schedule was very aggressive with the ground breaking on 8/2/2010 and the completion of Phase-1 Level-5 Commissioning on 6/24/2011 – just 326 calendar days with a 40-hour work week and a manpower peak of 212 electricians.  The Phase-2 build out was equally aggressive with a 6 month duration starting on 5/1/12 and Level-5 Commissioned on 11/14/12.

The electrical gear package of ACC6 was second to none in performance and included:  (2) 1200 Amp/35KV Outdoor Switchgear, (12) 5MVA/35KV/600V Outdoor Transformers, (24) 3000 Amp/600V Main Switchboards, (24) 3000Amp Critical Switchboards, (24) Parallel Isolation Switchboards, (24) 1300KW Rotary UPS Ling-ups, (24) 2250KW Diesel Generators, (40) Distribution Switchboards as well as various quantities of downstream Panels and Transformers.
