Prefab Gains That Pay Off in the Field

Taking work off-site delivers speed, cost, and quality gains your field crews will thank you for.

  • Labor Savings: Reduce onsite headcount by shifting tasks to controlled shop environments.
  • Fewer Errors: Shop-built assemblies minimize misalignment, rework, and costly fixes.
  • Faster Installs: Prefab packages let crews assemble quickly with plug-and-play components.
  • Improved Safety: Off-site fabrication reduces risk exposure for field teams.
  • Predictable Costs: Quantity takeoffs and BOMs give clarity on material needs.
  • Better Quality Control: Prefab assemblies pass QA before reaching the site.

FAQs

  • What is prefabrication in construction and how does it work?

    Prefabrication services are the opposite to manufacturing the building parts off-site (such as conduit racks or duct assemblies) and delivering either assemblies ready to be installed in the field.

  • How do mep prefabrication services reduce onsite labor and rework?

    Using coordinated BIM models, prefab assemblies are precisely constructed in the shop reducing field labor and avoiding pricey rework.

  • Which trades benefit most from prefabrication electrical services?

    The greatest advantage is to mechanical, electrical and plumbing contractors, particularly on large, repetitive assemblies.

  • What’s the difference between prefabrication and modular construction?

    The scope of construction prefabrication services is geared towards assemblies (duct racks, conduit bundles), whereas modular refers to whole sections such as rooms or pods.

  • How do you handle spooling, kitting, and assembly labeling for delivery?

    We offer spool drawings, kit breakdowns, and legible labeling to simplify shop fabrication and on-site install.

  • How is quality assurance managed for prefabricated assemblies?

    Assemblies are inspected by BIM models and successfully shop QA prior to shipping to site.

  • What deliverables do you provide (spool drawings, BOMs, cut lists, models)?

    We provide spool drawings, bills of materials, cut lists, prefabrication modelling and assemblies with labels.
