St. Louis – Completing 13 slip form silos in 18 months on the world's largest single-line clinker cement plant recently earned MC Industrial Inc. a Keystone Award, the highest honor bestowed by Associated General Contractors of St. Louis, for construction excellence. The silos were built for Holcim (US) on the firm's new plant in Ste. Genevieve County, MO.
Upon receiving the award, presented in the industrial/infrastructure category for projects valued over $20 million, MC Industrial President Tom Felton said, “This project is an outstanding example of what we can achieve when we bring all of the incredible talent and resources available in our company to focus on a project such as this.”
MC Industrial and joint-venture partner, Minneapolis-based T.E. Ibberson Co., began the design-build silo project in August 2006. MC Industrial workers logged more than 700,000 self-perform man-hours to place 66,000 cubic yards of concrete and 20.5 million pounds of rebar. Crews worked 24/7 during the 72 “slip days” to build five different types of silos ranging in size from the widest, 207 feet tall by 150 feet in diameter, to the tallest, 275 feet tall by 80 feet in diameter.
The Holcim (US) plan will begin producing 12,000 tons per day clinker in 2009.
