"The manufacturer has an early role, meeting with the architect, engineers, electrician, plumber, HVAC, and other subcontractors to coordinate the design with the qualities of their precast products. Design iterations and component details for a precast home take about a month to complete."

"Dukane reviews mechanical and plumbing layouts to ensure a smooth installation and compatibility with specified equipment. In addition, they invite contractors to visit their factory so they can get a better understanding of how openings are cast and how wall panels are constructed. To minimize the amount of on-site core drilling, foam block-outs are used to accommodate plumbing vents, mechanical chases, and other penetrations. During the pre-planning process, each contractor signs off on the plans before the concrete panels are cast in the factory. It simply requires coordination that makes the entire job flow better anyway."

"The manufacturer also provides recommendations on which coatings to use, electrical outlet placements, and the size and location of openings."

"Precast construction is a somewhat regional market, given plant availability and transportation costs. We feel that it is usually cost-effective within a 150-mile radius of any production plant, so our projects are focused strictly in the Chicago area."
