ABC Excellence in Construction Award
Plant Miller is Alabama’s largest coal-fired power plant. This ten-month project established the plant’s ability to receive limestone and inject it into the existing scrubbers, then dewater and dispose of the gypsum waste by-product.
This fast-paced project provided turnkey construction, including civil, structural, mechanical, electrical, and start-up activities. The major components included construction of a three-story dewatering facility with belt filter presses, associated process piping, conveying equipment, laboratory and office space; installation of slurry and other process piping/equipment inside two 190-foot-tall limestone silos; erection and fit-out for a 750-foot-long utility bridge; installation of a 500-foot-long gypsum conveying system; design-build services on a limestone storage facility housing a 360-degree radial gypsum stacker; and installation of associated truck scales and truck unloading apparatus.
