RCC Dam
Florida, USA
First RCC Dam in Florida
The C-51 Reservoir is a regional alternative water supply project for Southeast Florida designed to capture excess storm water currently wasted to tide and causing harm to the Lake Worth Lagoon. Phase I will provide about 17 mil. m³ of storage with an approximate depth of 11 meter - the majority of the storage is below groundlevel. It will also include engineered levees, reinforced concrete spillways, control structures and other facilities.
This project is the first roller compacted concrete dam in Florida and was fully constructed by contractor Phillips & Jordan.
During construction 7.40 m x 2.70 m upstream formwork units (comprised of two 3.70-m forms stacked on top of each other) is cycled in each placement section. The company split the dam into five placements each 400m. The 2.70 m x 1.35 m downstream formwork panels are placed on the horizontal steps and is cycled in further lifts after 3 x 1.20 m steps have been accomplished.

Going with Doka's formwork system has helped P&J stay on schedule, as well as streamline the RCC placement production. Their pricing was competitive, the lead times were reasonable, and deliveries were on time as promised.
