ABC Excellence in Construction Award
The Rotary Dumper Building Steel Replacement project consisted of the replacement of corroded steel in the below-grade area of the existing coal railroad car unloading facility. The building is located on the grounds of the CPS Energy Calaveras Lake coal-fired power plant in San Antonio, Texas. The project included replacement of structural, electrical, and mechanical components, and all work took place during a 60-day shutdown of the unloading facility.
In addition to the original scope of work, Brasfield & Gorrie provided a designed replacement for many additional areas of corroded structural steel and conveyor components that were found during the shutdown and required replacement prior to the resumption of operations.
The Rotary Plow and Coal Conveyor Installation project consisted of construction of a 1,126-foot-long reclaim tunnel located 32 feet in the ground as well as construction of associated buildings. The tunnel was equipped with a conveyor and coal plows. The project included installation of mechanical piping systems (compressed air, service water, and a sump drainage system) and modifications and upgrades to the legacy coal conveyor system. Equipment included a 1,637-foot-long, 72-inch belt conveyor; a 244-foot-long, 72-inch belt conveyor; a 270-foot-long, 66-inch belt conveyor; belt conveyor weigh scales; a dust collector; bridge cranes; a compressed air system; a belt plow; sump pumps; and a ventilation system.
Brasfield & Gorrie self-performed 20,983 cubic yards of concrete work and 270,000 cubic yards of site work.
