Cinergy FGD Project

Cayuga, IN

Construction on this project began in May of 2005 and is still ongoing. Patriot reports directly to the owner on this project, which is driven by emissions regulations provided by the Federal EPA. This project will have 6 to 8 major monolithic concrete placements ranging in size from 1500 cubic yards to 4000 cubic yards. These placements will form the foundations for the absorber unit and chimney section. Foundations for these new units will be placed on several hundred caissons drilled to 75 feet in depth with some being straight shafts and some being belled. Patriot is using a temperature monitoring system to monitor the differential core and edge concrete temperatures due to the mass of concrete being placed. For these mass concrete placements, a mix containing slag is being used to reduce the initial heat of hydration.
