Project Details

Due to new regulations, a temporary lined basin needed to be constructed to accept plant, process water. To prepare the sub grade, bottom ash and rock were excavated and removed from the site. A concrete forebay and five, 36” HDPE pipes were constructed and installed to maintain water flow. The completion of the project was the first of the multiple phases required to clean close the remaining basins.

Project Challenges & Solutions

Water Level Management

Trans Ash employed a water management subcontractor to install hundreds of well points and remove the sub surface water to keep the work area safe and ensure the water remained below the specified elevation.

Changing Conditions

Trans Ash utilized an excavator with a hammer attachment to demolish an unexpected section of rock, while working concurrently on other project activities.

Sub Grade Construction

The biggest challenge of the project was placing a sub grade of #57 stone, to grade, on the slopes of the forebay below the concrete. Trans employed an additional work force and multiple surveyors to continually check grade and adjust, as necessary, to maintain grade until the concrete was ready to be poured.
