The Pentagon serves as the headquarters for the U.S. Department of Defense and is one of the world’s largest office buildings. Singleton was selected to help complete a renovation on Wedge 1 that included a complete update to the space’s electrical infrastructure. The project included two new 15kv vaults, 15kv switchgears, eight network transformers, mission-critical UPS systems, power distribution, 80 electrical and 120 communications closets, and an information management and telecommunications backbone. Due to the mission-critical operations within the Pentagon, Singleton performed construction in phases, ensuring that the building remained in full use.

However, as the Wedge 1 project neared completion, the September 11th terrorist attacks devastated about one-third of the space. As a result, Singleton took on the task of renovating the damaged areas as part of the Pentagon PRAC/Phoenix Project.

The rebuild included a complete replacement of the previously installed 15kv vaults. The timeframe for completing the Phoenix Project was extremely tight in order to meet the Pentagon’s schedule for tenants to reoccupy the space just one year after the attacks. Site access and storage were limited during the rebuilding, and Singleton worked closely with other contractors on the project to coordinate key tasks. The rest of the building remained occupied, with a phased turnover of completed tenant spaces.

Singleton won numerous awards for their role in the Phoenix Project, including the WBC Star Award for Excellence in the Face of Adversity.
