Permanent Modular Construction Methods

Permanent modular construction (“PMC”) is an alternative construction method that means doing more in advance of the building site. Sometimes called “Off-Site” construction, we build “Volumetric” building blocks to near completion with flooring, walls, ceilings, lighting and systems. We manufacture all of it indoors under controlled conditions. After completion, we transport it to the site. Modular buildings can be single or multi-story, steel and/or concrete structures with nearly limitless customization options.

Given that site work and fabrication run concurrently, “PMC” projects save time compared to traditional forms of construction.

Research shows that traditional site built construction is less efficient and less productive: See “Improving Construction Efficiency & Productivity with Modular Construction” (downloadable from our Resources page) and McGraw-Hill Report “Prefabrication and Modularization Increase Productivity”. Most recently, a study of “Permanent Modular Construction, Process, Practice, Performance” by The National Institute of Building Sciences and MBI Educational Foundations”, provides case studies and speaks to the best practices of modular construction. These include the benefits of early team formation and collaboration. These resources provide facts about the advantages and savings with “off site” construction.

The American Institute of Architects (AIA) have written about the efficiencies associated with modularization. Advancements in design technology, Building Information Modeling (BIM), further enables collaboration between designers, engineers, modular fabricators and building installers. Moreover, Design-Build forms of project delivery, integrated approaches to construction, and owners’ willingness to depart from traditional Design Bid Build has helped pave the way for more successful modular projects around the World.

In the How To section of our website, we explain why teams who still utilize “Design –Bid – Build”  (maximizing competition over collaboration) should not try modular. With modular, the people who design your new school or office space need to consider information from downstream subcontractors. For example, even the crane size and reach will have a bearing on early design decisions. With that said, please visit the How To section of our site for information on how to get both free information and valuable advice.
