Overholser Water Treatment Plant Improvements
In 2016, Preload’s project team successfully completed this 5MG AWWA D110, Type III prestressed concrete tank as a subcontractor on the decades old Overholser Water Treatment Plant in Oklahoma City, OK. This unique project utilized the caisson supported floor of the previous welded steel tank to support the new, upgraded prestressed concrete tank.
Preload Engineer Brett Henning collaborated closely with engineers at Carollo to develop a floor design which incorporated the caisson supported concrete foundation of the existing steel tank. The steel tank was demolished and Preload Area Manager, Bob Barbarisi, coordinated with the General Contractor to install additional perimeter caisson to allow for an increase in tank diameter. Preload Project Engineer, Tim Halloran’s communication between Sherman Thayer regarding onsite changes for caisson extension and modifications was critical in the successful installation. Sherman Thayer was highly effective in managing tight site conditions under an accelerated schedule.
