Oak Ridge, Tenn.-a key distortion between two federal authorities marked the completion of the construction work in the K-25 interpretation center, an important milestone in the preservation of the history of the OAK Ridge Reservation. The center offers visitors a panoramic view of the footprint of the historic gas diffusion plant for the coming generations.
The OAK Ridge Office of Environmental Management of the US Ministry of Energy leads the environmental adjustment efforts throughout the OAK Ridge Reserve and deals with the legacy of decades of state research and the development of nuclear weapons. However, the construction of an interpretation center to commemorate the K-25 location required a unique partnership with the Nashville district, Nashville Corps of Engineers.
Lieutenant Colonel Robert Green, commander of the Nashville district, said: “This was a great partnership with Orem. We focus on what we can do best in our respective government branches – the corps are characterized by the building, and this project is proof of this. “

The Nashville district completed the construction of the K-25 interpretation center and transferred the project on March 4, 2025 with a key exchange to the US Energy Ministry.
“We are very satisfied with this cooperation and partnership,” said Orem manager Jay Mullis. “Such a vertical construction is not often, and it is certainly not in the steering house of most of our contractors. It was an invaluable advantage to cope with this part of the project. It is a great opportunity for our two agencies to use the strengths of the other in a sensible way. “

The event between USAACE and DOE Partners included a meet-and-greet tour through the newly built building, followed by the symbolic turnover of the facility.
The K-25 Interpretation Center has a viewing platform on which visitors can overlook the 44-hectare footprint of the K-25 enrichment system, the largest structure in the world when the Corps of Engineers built it as part of the Manhattan project during the Second World War.
The district of Nashville directed the construction of the previous 87-foot 4-foot metal building with a 55-foot 4-foot observation deck. It comprises about 7,000 square meters of exhibition and viewing area. Geiger Brothers from Jackson, Ohio, worked as a contractor for the project between $ 9.9 million and international support construction project.

The construction of this facility and the exhibitions of the route are the final components of a multi-project agreement that was signed in 2012 to commemorate the history of the former Oak Ridge Gasous diffusion plant in which the K-25 building was located.
When Green saw the side for the first time, he noticed: “It is impressive. When you visit this place, you have a feeling for the enormous footprint for the facility that was once the facility. The historical meaning of this place and the extent of the facilities really convey the meaning of what was here before.”
The project is of particular importance for the US Army Corps of Engineers, since it brings the full circle of its participation-from the construction of the K-25 gas diffusion system from 1943 to 1945 to the creation of the interpretation center, which is devoted to the preservation of its history.
“This project has historical importance and connects us to our roots,” said Green. “The Corps played a key role in the construction of the original K-25 project. Through the contribution to a historical interpretation center, people can celebrate their legacy and contribute to understanding the role of the corps.”
While the construction phase has been completed, Orem continues to work on the grinding, including landscape design and exhibition installation. The opening is expected in autumn 2025.
Managers and project managers of the US Army Corps of Engineers Nashville, the district of Nashville, and the OAK Ridge Office of Environmental Management of the US Department of Energy will meet on March 4, 2025 to build a successful partnership and the completed construction of the K-25 interpretation center at the East Tennesse Technology Park in OAK Ridge, Tennessee to celebrate. The building includes a viewing platform where visitors can see the area in which the K-25 gas diffusion process was built up, which is once enriched and the project was in Manhattan. The K-25 building was discontinued from June 1943 until the end of the company in 1987. Since then it has been demolished due to environmental dangers and a reduction in structural integrity.

“There are some work to fulfill. We will end the exhibits and objects of interpretation. We are planning a large opening in September. “Said Mullis.
Mullis and Green hope that the project promotes tourism and raises awareness of the historical site, especially after its opening in September 2025.
Green adds: “I hope the community appreciates and enjoys this project as well as me. This is a special place for our country and the region, and I hope you come out and experience it. “
