Contract: $5.5 M
The cast-in-place concrete for this pharmaceutical company’s wastewater treatment facility includes 17′ high cast-in-place radius walls for the bio-reactor digesters and clarifiers.
The bio-reactor cast-in-place 30′ slabs required over 30 placements with an extensive water stop detail at each construction joint. The walls for the bio-reactor were also limited to a maximum 30′ pour break along with water stops at each joint.
Over 30% of the cast-in-place walls were topped with a cast-in-place walkway and work platform. These platforms were completed with a wall-mount flying table system. As a part of Gannet Fleming’s team, Donley’s placed 8,000 cubic yards of concrete and 750 tons of reinforcing steel to create this state-of-the-art waste water treatment facility.
