M. Cooper Supply (Orland Park, IL), a plumbing wholesaler since 1938, announced plans to break ground for an 80,000-sq.-ft. warehouse in Mokena, IL, in December. This would serve as the new corporate headquarters for the company, serving the Chicagoland market. It will feature an all-indoor dock facility with crane capacity for more efficient material handling. The building is expected to be completed by August 2007.
