URS|CH2M Oak Ridge (UCOR), an AECOM-led team, supports the U.S. Department of Energy (DOE) in removing numerous environmental hazards and millions of square feet of old facilities at the East Tennessee Technology Park (ETTP, Oak Ridge, Tennessee, U.S.), former home to the Oak Ridge Gaseous Diffusion Plant. This cleanup included demolition of the massive K-25 Building, one of the largest buildings in the world and the largest demolition project in DOE history.

UCOR has now decontaminated, decommissioned, demolished and disposed of all five gaseous diffusion plants once used for enriching uranium, ahead of schedule and under budget. Acceleration of these demolitions has contracted the workscope and saved hundreds of millions of dollars to be applied to other DOE Environmental Management activities at the Oak Ridge National Laboratory and Y-12. Since completing DOE’s ETTP Vision 2016 nine months ahead of schedule and $millions under budget, UCOR has been working with its client, regulators and stakeholders on work required to achieve a final end state for ETTP, which will become available for commercial industrial use and regional business development.

UCOR is one of six AECOM companies to win DOE’s most prestigious safety honor — Voluntary Protection Program (VPP) “Star Status”—and won a top safety award in its class from the National Safety Council for 2017.
