75 Years Supporting the Department of Energy

With a company history of 75 years supporting the Department of Energy (DOE), Day & Zimmermann and SOC together have provided Safeguards, Security, Emergency Services, Management & Operations (M&O), Architecture and Design (A/E) services to protect national security assets that include Category I Special Nuclear Material in research, development, and manufacturing environments.

Currently, SOC fills a critical role in protecting the research and development that supports the nation’s nuclear deterrent and other important national security missions. SOC delivers award-winning security and emergency services operations solutions for five U.S. Department of Energy (DOE) sites, providing protection of personnel, equipment, facilities, and assets around the clock. The DOE sites supported include: the Strategic Petroleum Reserve, Nevada National Security Site, Pantex Plant, Y-12 National Security Complex, and other DOE locations.

Previously, for more than twenty years, SOC provided best-in-class Safeguards and Security services at Los Alamos National Laboratory, one of the largest national laboratories supporting DOE, safeguarding national security assets in a federally-funded research and development environment.

"All accounts point to an absolutely flawless security operation. The [DOE] Secretary's visit pointed to a high level of preparedness and professionalism. Another great deed done well."
