Contractors see prefabrication as a key component for increasing productivity and efficiencies throughout the construction process. Benefits of prefabrication include:
- The reduction of wasted materials.
- Increased job site safety, due to having fewer materials and workers on site.
- Decreased field installation time.
The use of Building Information Modeling (BIM) during preconstruction makes many of these prefabrication opportunities possible. The use of highly-detailed and coordinated 3D models of architectural, structural, and MEP systems allows each trade contractor to be confident their system will install and fit as shown.
Trade contractors with BIM capabilities can take advantage of the opportunities that pre-fabrication provides. Using specialized software allows them to create a fabrication-level 3D model. This 3D file is then used in a Computer Aided Manufacturing (CAM) machine that creates the building component or part.
Jim Norton, P.E., is Vice President of Walton and Company, a design-build mechanical contractor. When asked how BIM directly impacts his company, Jim said,
“Thinking and drafting in three dimensions not only teaches our designers and engineers to think beyond lines on a page, but also allows us to leverage prefabricating piping and ductwork with more confidence.”
Kinsley uses BIM to coordinate the design, which allows for prefabrication opportunities that can reduce installation time and costs. Using BIM for prefabrication is another tool that helps Kinsley efficiently deliver successful projects.
