White Oak Dam Modifications

  • Project involved modifications to White Oak Dam to bring the embankment into compliance with Tennessee dam safety regulations. The following modifications were implemented by DEMCO through this scope including: grouting the box culvert under the southern end of the embankment, reducing the slope on the upstream and downstream faces of the embankment, and armoring the slopes to protect them against erosion, failure from flooding, and overtopping. Because the sediments are radiologically contaminated, efforts were required to avoid unnecessary disturbance of the sediments that could suspend them in the water for transport further downstream.

  • Performed safely with not even a first aid with 10,283 man-hours expended.
  • No radiological personnel contaminations.
  • 531 cubic yards of concrete placed.
  • 18,822 tons of shot rock, rip-rap, and filter aggregate placed.
  • Performed activities in boats on contaminated waters without incident.
  • Successfully and safely controlled traffic on State Route 95.
  • Successfully and efficiently dealt with client engineering changes.
  • Project completed with no punch list items and to the satisfaction of DOE and Bechtel-Jacobs.
