Permanent modular construction is simply an alternative method of construction, built off-site under controlled conditions in significantly less time, with no restrictions in the choice of building design, layout or mechanical systems. They can be single or multi-story, steel and/or concrete structures and custom designed by Architects.
The American Institute of Architects (AIA) and many others have written about the efficiencies associated with pre fabrication and modularization especially given advancements in design technology such as Building Information Modeling (BIM) which further enables collaboration between designers, engineers and fabricators. There is a wide concern about efficiency or lack thereof in traditional construction methods and much of the problem is found in pre construction decision making. The Modular Building Institute’s “Improving Construction Efficiency & Productivity with Modular Construction” and a McGraw-Hill Construction Report “Prefabrication and Modularization Increase Productivity”, both speak to the enabling forces that are empowering project teams to be more efficient with the use of pre fabrication.
