MODELLING

LOD 300/350/400 MEP Modelling Services

Mechanical, electrical, plumbing and fire protection models built to the LOD your project stage actually needs — LOD 300/350 for design coordination, LOD 400 for fabrication-ready construction delivery.

This capability is delivered through a named engagement

This work isn't quoted as a standalone line item — it's delivered as part of BuildPath Sprint or Fab-Ready Package, scoped and guaranteed at the engagement level.

The Problem

What goes wrong without it

  • Design-stage models look coordinated but aren't detailed enough to fabricate or install from.
  • Upgrading an LOD 300 model to LOD 400 late in the schedule creates rework across every discipline at once.
  • In-house teams are stretched across design and construction-stage detailing at the same time.
Our Solution

How OmegaBIM approaches it

Early-stage work is modelled to LOD 300/350 for coordination against architectural and structural intent. Contractors moving into fabrication get LOD 400 — real fittings, real supports, real clearances — so the model handed to the fabrication shop is the model we delivered, not a rushed late-stage upgrade.

Workflow

The same four-stage delivery model, applied to lod 300/350/400 modelling.

01

Intake & Setup

Federated model built to your worksharing standard, target LOD and naming convention before routing starts.

02

MEP Modelling

Mechanical, electrical, plumbing and fire systems routed and sized by discipline specialists to the agreed LOD.

03

Coordination & Clash

Structured clash rounds against architectural and structural, resolved to a documented model — clash-free sign-off on LOD 400 contractor engagements.

04

Handoff

LOD 300/350 issued for design documentation, or LOD 400 issued with fabrication-ready shop drawings.

Frequently asked

What's the difference between LOD 300, 350 and 400?

+

LOD 300 shows systems sized and positioned for design coordination. LOD 350 adds interface and connection detail between systems. LOD 400 adds real manufacturer fittings, supports, sleeves and fabrication detail — the level needed to build from, not just design from.

What LOD does a BuildPath Sprint deliver to?

+

LOD 350, coordinated and route-optimized. Earlier design-stage work is typically LOD 300/350; fabrication-ready output moves to LOD 400 through the Fab-Ready Package.

Can you take an existing LOD 300 model and upgrade it?

+

Yes. We audit the existing model first, flag what needs rework, and upgrade it discipline by discipline rather than starting over.
