This report offers a set of best practices for HVAC and sheet metal contractors to optimize the use of prefabrication to obtain peak productivity. Based on an industry survey, a series of case studies, and the completion of detailed productivity and prefabrication analyses, a number of best practices are presented as tactics that other sheet metal contractors might use.
The report adds to the understanding of how productivity of field and office personnel is measured and identifies the impact of prefabrication on both field and office operations for HVAC and sheet metal contractors. The impact and use of prefabrication within Lean Construction, BIM and VDC is also explored.
This final report includes three different types of suggested tactics; one for the contractor who is new to prefabrication in the sheet metal shop; one for those seeking to dramatically increase prefabrication efforts; and some tactics for the advanced prefabricator.
