Building Information Modeling (BIM) is an integrated process that enhances the design, construction, operation and maintenance of the facility. While many companies talk about BIM, The Hill Group began integrating this technology into our construction process systems in 2003. Today we are recognized as the Chicago area’s BIM-capable leader in successful pre-construction planning, design, prefabrication, purchasing/inventory control, construction management, commissioning, test and balance, and building operations.
