Clash Detection Services & BIM Coordination
Federated model clash tests in Navisworks, clear reports with viewpoints, and issue tracking until every conflict between MEP, structure and architecture is closed, before it reaches site.
BIM365 provides clash detection and BIM coordination services for general contractors, MEP engineers, architects and trade contractors. We bring every trade model into one federated model, test it, and turn hundreds of raw clashes into a short list of real problems with a clear owner for each.
Coordination is run by a senior MEP BIM coordinator with 7+ years in coordination meetings on live projects, so clashes are judged by someone who knows how services are installed, not only how they look on screen. See all our BIM services.
Scope
What We Check
Hard Clashes
Ducts through beams, pipes through columns, cable trays through walls: every place two elements occupy the same space.
Clearance Clashes
Insulation, access to valves and dampers, working space in front of electrical panels and the zone below sprinkler heads.
Ceiling Voids & Risers
Crowded corridors, plant room exits and shafts, where duct, pipe, tray and sprinkler mains all fight for the same depth.
MEP vs Structure
Penetrations through slabs, beams and walls checked early, so openings and sleeves can be planned before the concrete is poured.
MEP vs Architecture
Services against ceilings, bulkheads, doors, windows and fire-rated walls, including the space needed for ceiling grids.
Coordination Meetings
Weekly clash rounds timed for your meeting, with the report ready to walk through and actions agreed with each trade.
The deliverable
What Is in Our Clash Report
Raw clash counts are useless. A report your trades can act on groups the clashes, removes duplicates and says who fixes what by when.
| Item | What you see |
|---|---|
| Summary | Clashes per test and per level, new, active and resolved since the last round. |
| Grouped issues | Related clashes grouped into one issue, so 40 hits on one duct run become one item to fix. |
| Viewpoint | A saved 3D view and screenshot of each issue, with grid line and level. |
| Owner and priority | The trade responsible, priority (critical, high, normal) and target round to close. |
| Suggested fix | A short note on how to solve it, such as drop the pipe 150 mm or reroute the tray along grid C. |
| Formats | PDF or HTML report, Navisworks NWD with saved viewpoints, and BCF or ACC issues if your team uses them. |
How it works
Our Clash Coordination Process
- Model check. We check every trade model for shared coordinates, levels and missing elements before testing, so the results mean something.
- Clash matrix. Tests and tolerances set per trade pair, agreed with you and recorded in the BEP.
- Run and group. Tests run in Navisworks, false hits filtered out, real clashes grouped into issues.
- Report and assign. Each issue gets a viewpoint, an owner, a priority and a suggested fix.
- Re-test until closed. Updated models re-tested each round until every area is clear and signed off.
Try Us Before You Commit
- Free 20-minute model review: share your models and we tell you where the problem areas are.
- One paid pilot round: one level, one clash round, a fixed price. Judge the report before you commit.
- Revisions until it matches: if the report does not meet the agreed scope, we fix it at no extra cost.
- NDA before files move: we can work inside your ACC, BIM 360 or SharePoint.
What we need
To Start Coordination
- Trade models in RVT, NWC, DWG or IFC, on shared coordinates
- Your BEP, clash matrix or tolerances, if you have them
- The levels or zones to coordinate first
- Your coordination meeting day and time
- How your team tracks issues: report, BCF or ACC
What you get
Each Round
- Federated Navisworks model (NWD) with saved viewpoints
- Clash report grouped by trade, level and priority
- Progress summary: new, active and resolved issues
- Resolved MEP model, if we also hold the MEP scope
- A coordinated model ready for shop drawings and installation
