Cedar Creek – Water Pollution Control Plant
Tanks being built with PERI GRV Circular Wall Form System
General contractor N. Kruger Inc., out of Oyster Bay, New York has teamed up with PERI on a project to improve the Cedar Creek Water Pollution Control Plant.
The project, which is being built for the Nassau County Department of Public Works, consists of constructing six Final Sedimentation Tanks and a 150'' (45.70 m) by 45'' (13.70 m) by 33'' (10.05 m) high Return Activated Sludge Building.
The final Sedimentation Tanks are each 110'' (33 m) in diameter and 17'' (5.1 m) high. Kruger chose to erect formwork for the complete 360 degree interior so that wall reinforcing could be placed uninterruptedly. The exterior forms are 180 degrees in accordance with the required construction joint locations.
PERI provided its GRV Circular Form System to meet these criteria. By precise location of the GRV waling members, the PERI design team was able to provide a form with only three ties in section, spaced horizontally at 4''-6" (1.35 m) on center, thereby achieving 51 sqft of concrete surface area per tie. The weight of the formwork is only 12.5 pounds per sqft, and the Finn Form facing provides the best plywood surface finish possible.
The form choice for Kruger at the R.A.S. building, was the PERI TRIO Gang Form System. As with many structures of this nature, there are many embedded items and penetrations which greatly affect the formwork configuration from one placement to the next.
The only necessary connector is the PERI BFD clamp.
