Clash detection that gets clashes fixed
A clash found in the model costs a few minutes. The same clash found on site costs days, materials and goodwill. We run clash detection that cuts through the noise and gives your team a short list of real problems, each with an owner.

From raw clashes to real decisions
The problems design and site teams bring to us, and how clash detection fixes them.
| Challenge | How we solve it | Result |
|---|---|---|
| Thousands of meaningless clashes | Tolerances, exclusions and grouping by cause | Short, actionable issue lists |
| Nobody owns the issue | Each issue assigned to a discipline and person | Faster resolution in meetings |
| Same clashes keep coming back | Status tracked across every run | Visible progress over time |
| Ceilings too tight for services | Soft clashes for access and clearance zones | Buildable, maintainable voids |
From models to resolved issues in six steps
A repeatable clash cycle that shows progress at every coordination meeting.
-
Step 1
Collect models
Latest models from every discipline.
-
Step 2
Federate & align
Shared coordinates and levels checked.
-
Step 3
Run tests
Clash matrix by discipline, zone and tolerance.
-
Step 4
Group issues
Noise filtered, real conflicts grouped.
-
Step 5
Report
Views, locations and owners for each issue.
-
Step 6
Track & repeat
Resolved issues closed, new ones raised.
Fewer surprises on site
Anyone can press 'Run' on a clash test and get ten thousand clashes. That report helps nobody. The value is in what happens next: setting sensible tolerances, ignoring what doesn't matter and grouping the rest into issues a team can actually discuss.
We agree a clash matrix with you at the start, by discipline, zone and tolerance. Then we run the same tests at every model drop, so it's easy to see what's been fixed, what's new and what keeps coming back.
Each issue arrives with a clear view, its grid and level, the elements involved and who needs to act. Reports are built to be worked through in a coordination meeting, not filed away.
We work from
- Architectural model
- Structural model
- MEP and fire protection models
- Agreed tolerances and priorities
- Coordination schedule
- Your issue-tracking platform
Federated models
All disciplines combined and aligned to shared coordinates.
Targeted clash tests
Tests set up by discipline pair, zone and tolerance.
Grouped clash issues
Thousands of raw hits grouped into real, actionable issues.
Clear reports
Views, locations, levels and responsible trades for each issue.
Issue tracking
Status tracked from open to resolved across each run.
Meeting support
Reports prepared for, and reviewed in, coordination meetings.
Clearance checks
Access, maintenance and headroom zones checked as well as hard clashes.
Regular cycles
Weekly or milestone-based runs that track progress over time.
Clash reports that lead to decisions
Our coordinators know what each trade can realistically move and what it can't. That judgement is what turns a clash report into decisions. Every project starts with a written quotation, a named point of contact and a firm delivery date, and you can begin with a small trial task.

Your standards first
We work inside your templates, title blocks, families and naming, so files drop straight into your workflow.
Qualified AEC team
Architects and engineers who know how drawings and models are used on real projects.
QA on every delivery
A separate reviewer checks accuracy, completeness and sheets against the brief before files leave us.
Work in your time zone
Shifts overlap US and UK working hours for calls, reviews and quick turnarounds.
Confidential by default
NDAs on request, controlled access and secure file transfer for every project.
Scales with your workload
Add capacity for a deadline and scale back when it passes, without hiring.
Work with us your way
Three simple ways to engage, each with a written quotation before any work begins.

Clash detection questions
Quick answers about software, reports, tolerances and frequency for clash detection.
We work in the project’s own coordination platform and share issues in an open format for teams on other platforms.
No. We federate models from any authoring platform through native or open-standard exports.
Tolerances, sensible exclusions and grouping by cause. A typical first run might show thousands of hits; the report you see will be a few dozen real issues.
Weekly during active coordination is common. On smaller projects, at each design milestone is usually enough.
If we’re also modeling the discipline involved, yes. Otherwise we report clearly so each consultant fixes their own elements.
Yes. Access space, insulation, door swings and headroom often matter more than the hard clashes, so we test for them too.
Grouped issues with screenshots, location, elements, responsible trade and status, plus a one-page summary of progress since the last run.
