Led by an experienced demolition group, Envirocon recently completed a competitively bid ash silo demolition project at a large power generation facility in Tennessee. This pilot project from the client for future plant demolition and coal ash site related closures began with the installation of important storm water pollution controls to protect the adjacent waterway from potential disturbances.
Envirocon performed minor asbestos abatement in the silo truck bays by removing caulking prior to conducting Structural and Hazmat surveys on the structures scheduled for demolition. These structures included a scale house, silo equipment building, 36-foot silo support structure, and two 50-foot diameter, by 50-foot tall steel ash silos mounted to the top of the support structure.
While onsite, the team also removed a 12-foot diameter by 10-foot deep concrete sump and its associated trenches, 30,900 square feet of 18-inch thick concrete drives, and the 10,400 square foot, 3-foot thick silo foundation. All disturbed areas were backfilled, and the client handled final site restoration.
The five-week demolition project adds to the long list of Envirocon projects performed at power generation facilities and marks the first of hopefully many for this important client.
