This paper focuses on off-site construction from the perspective of prefabrication, and installation of preassembled building components within “traditional” site-built construction project delivery methods or systems.

The paper validates the savings identified in earlier reports and adds definition and dimension to the advantages associated with prefabrication and modularization in the MEP and HVAC and sheet metal industries. It presents a series of industry informed recommendations for contractors using or contemplating the use of prefabricated/modularized systems.
