MEP Coordination

MEP Coordination Drawings & Clash Detection in Dubai

Bonarch Draft prepares MEP coordination drawings in Dubai for architecture firms, consultancies and fit-out contractors: we combine your consultants’ MEP and structural models with the architecture in Navisworks, resolve the clashes and issue combined services drawings. Coordination is priced per project after we review your models, and a one-off coordination round on a finished model takes around 1–3 weeks.

What we coordinate

We coordinate the models your consultants produce, checking every MEP system against the architecture, the structure and each other.

Mechanical & Plumbing
  • HVAC and ductwork
  • Water supply
  • Drainage and rainwater
  • Fire fighting and sprinklers
Electrical & Low Current
  • Power and cable trays
  • Low current: data, CCTV and fire alarm
  • Ceiling lights and diffusers

 

Against the Architecture
  • Beams, slabs and columns
  • Walls, including fire-rated walls
  • Ceiling voids and heights
  • Openings in walls and slabs

MEP calculations and design stay with your MEP consultant; our role is coordination only. For the architectural and interior model itself, see our BIM modeling service.

How we Work

You send the discipline models: architectural, structural and MEP. For meaningful coordination, MEP models should be at least LOD 300.

Federation: we combine the models in Navisworks and run clash tests between each pair of disciplines.

Clash review: clashes are grouped, false clashes are removed, and the rest are prioritised.

Clash report: each clash comes with a proposed resolution and the discipline responsible for fixing it, delivered as HTML or Excel, or as BCF for ACC and Revizto.

Coordination drawings: combined services drawings, ceiling void sections, builder's work drawings and a coordinated RCP, where your scope includes them.

What you receive

Every coordination round produces a combined coordination model and a clash report. Where your scope includes coordination drawings, we also deliver combined services drawings showing all systems on one plan, ceiling void sections, builder’s work drawings for openings in walls and slabs, and a coordinated reflected ceiling plan (RCP).

What your MEP models need for coordination

The LOD of MEP models is set by your consultant, since they produce them. For meaningful coordination, MEP models should be at least LOD 300: correct geometry, size and position for ducts, pipes and trays. At LOD 350 they also show connections, supports and maintenance clearances, so coordination can go further.

The clashes we find most often

The conflicts that come up on almost every project:

  • Ducts clashing with beams, or ducts crossing fire-rated walls without fire dampers
  • Not enough depth above the ceiling, especially in corridors where every system runs
  • Sprinklers clashing with light fittings or diffusers
  • Drainage pipes clashing with beams, since they need a fall and can’t simply be moved
  • Cable trays clashing with ductwork
  • No access space left for equipment maintenance

One-off or ongoing coordination

Coordination runs in two ways:

  • One-off, on a finished model: around 1 to 3 weeks for a fit-out or villa
  • Periodic, during the project: a clash round and a coordination meeting every one or two weeks, until the end of the design stage
