1947 - Today
Pantex Plant | Y-12 Sites
In 1947, Mason & Hanger designed (A/E) the Pantex Plant. For more than four decades (1956-2011), we provided management & operations (M&O) services at the mission-critical plant.
From the very onset, protecting our employees, the general public and the plant has been our number one priority, and training has played a pivotal role in maintaining this commitment. In the late 1950s, we proudly designed Pantex’s education training center, a facility that improved the learning process through the use of visual aids and movies produced in onsite television studios.
We provide the award-winning protective force operations in support of the Pantex and Y-12 sites including perimeter control, static guards, access control, Special Response Teams, Fire, EMS, and Hazmat operations. Our successful protective force operations have earned three NNSA awards for security operations, the Bradly A. Peterson Federal Contractor Security Professional of the Year, NNSA Security Manager of the Year Award, and the NNSA Outstanding Security Team or Group award.
