Prefabricated and Modular Construction

Today architects, designers, and construction professionals are making major advancements with new innovations and approaches. From sustainable infrastructure to mass production of affordable housing, discover how the AEC industry is revolutionizing the world with prefabrication.


What is prefabrication?

Prefabrication begins with building elements created off-site in a factory or workshop. Once completed, these components are then transported to the site for assembly. With this shift in the construction approach, time, cost, and labor are dramatically reduced.


Benefits of prefabrication & modular construction

    Controlled environment

    By building in a controlled and consistent environment, there is greater quality control in what is built and gives better predictability to the outcome of the project.

    Less waste

    With controlled factory settings, waste is significantly reduced because excess materials can be recycled on-site into other processes. Controlled storage also reduces material damage from weather.

    Increased safety

    Prefabrication puts workers in a controlled environment where many of the risks of traditional construction sites, such as working at heights and around weather conditions, can be avoided.

    The Modular Building Institute estimates projects are completed 30 to 50 percent faster than traditional construction, taking a project from conception to completion quickly and easily.

How prefabrication is helping solve the housing crisis in the Bay Area

In a massive Vallejo, California off-site construction facility, Factory_OS is industrializing the way housing is built. The company improves productivity and efficiency by constructing modular units on an assembly line in a controlled factory setting to send on-site to make multifamily buildings. Its manufacturing technology allows the company to build high-quality homes 20% cheaper, 40% faster and with 70% less waste than traditional building construction.

What is BIM's role in prefabrication?

Building information modeling (BIM) tools provide the key to much of the advancements in modular assembly as they allow for a detailed 3D visualization of components to ensure that the finished parts fit. BIM also provides the means to detail each component for precise manufacturing that may include wall-assembly templates and jigs, subassemblies that fit within wall frames, and automotive approaches such as robotic welding.
