OAK RIDGE, Tenn. – Officials celebrated progress on a facility here last week that will give the public a new perspective of what was once the world’s largest building as they broke ground for the K-25 Viewing Platform at the East Tennessee Technology Park.

Through an interagency agreement signed last year, the Oak Ridge Office of Environmental Management (OREM) provided the funds for the project, while the U.S. Army Corps of Engineers (USACE) will oversee its construction. Geiger Brothers was awarded the $9.9 million contract to build the facility.

“It couldn’t be scripted any better that the agency responsible for the birth of Oak Ridge would be the one to help build the infrastructure that shares the history and accomplishment of that original story,” OREM Deputy Manager Laura Wilkerson said of USACE.

The K-25 Viewing Platform will be adjacent to the recently opened K-25 History Center and provide visitors with a complete view of the building’s massive 44-acre footprint.

Its construction is one of the final components of a multi-project agreement OREM signed in 2012 to commemorate the history of the former Oak Ridge Gaseous Diffusion Plant, where the K-25 Building was located. OREM completed the other elements in previous years, which included the construction of the K-25 History Center and the preservation of the historic Alexander Inn.

The K-25 Viewing Platform is expected to be complete and open to the public by late 2024.
