Cliffside Modernization

The estimated $1.8-billion project includes a new 800-megawatt, supercritical, coal-fired generating plant and a flue gas desulfurization system, which will allow the plant to produce twice the amount of electricity with fewer emissions.

For the foundation slab and the pedestal, Shaw is using Doka's framed formwork Frami, selected because it was the perfect height: only two sizes of Frami panels (six foot and nine foot panels) were needed on the multiple structures. A total of 9,000-square-feet of Frami was used for the foundation and 14,000-square-feet for the pedestal. Doka's framed formwork Frami was also used in the construction of the ball mill to pour the 18-foot high high pedestals. This system eliminated the need for multiple ties and only one horizontal panel joint was required for the pour. Another challenge on this project was the boiler/feed water structure, which had heavy foundations, large columns and a two-level, heavy elevated slab. Doka supplied Frami to form the foundations and 5-foot thick shored slabs.

The new advanced clean coal unit is projected to come online in 2012, and Shaw Contractors is confident they can meet the construction schedule to keep the "lights on" for Rutherford and Cleveland counties' residents.
