Prefabrication enhances all major elements of a project: cost, schedule, safety, and quality.

Prefabrication is the assembly of building units or components at a workshop or factory separate from the jobsite. During preconstruction, Messer’s experts will analyze the project scope and the supplier/subcontractor marketplace to determine if prefabrication opportunities exist for your project.

Prefabricated Units & Components

Prefabrication can come in many forms, including but not limited to:

  • Mechanical/electrical/plumbing (MEP) system assemblies, such as ceiling racks
  • Bathroom pods
  • Health care headwall assemblies

Mechanical, electrical, plumbing, and fire protection systems were assembled in an offsite warehouse.

The prefabricated racks were then delivered to the jobsite and loaded into the building.

Benefits of Prefabrication

When implemented effectively, prefabrication is a benefit to a project’s cost, quality, safety, and schedule. Prefabrication also enhances end-user satisfaction and sustainability.

Cost Savings

  • Improves cost control by eliminating variables, like inclement weather
  • Waste is minimized at the jobsite, reducing costs for General Conditions (dumpsters and clean-up)
  • It removes the variation in on-site manpower, effectively reducing items such as portable toilets and subcontractor parking areas

Schedule Savings

  • Prefabricated components can be built in the process – e.g. above-ceiling mechanical racks can be built before the floors are complete

Enhanced Safety

  • The reduced amount of material deliveries minimizes traffic and improves safety for your occupants as well as construction workers
  • When above-ceiling components are prefabricated, contractors are working in ergonomically-comfortable positions (not on ladders), reducing the risk of falls

Enhanced Quality

  • All items are constructed in a controlled environment, which means they are free from exposure to weather
  • Materials are typically tested in the warehouse (off site), and then re-tested once they are installed, ensuring every piece and part fits perfectly
  • Using Building Information Modeling (BIM) further enhances quality and reliability by removing potential material clashes before they occur

Enhanced Maintenance & Operations

  • Maintenance staff can attend preconstruction meetings to help ensure the design and construction of prefabricated elements are done with maintenance considerations in mind

Sustainability

  • Waste is significantly reduced at both the shop and project locations because materials are ordered in specific lengths
