Clash Detection Services That Find Every Conflict Before the Field Does

Eagle BIM delivers clash detection services that systematically test all discipline models against each other — architectural, structural, MEP, and civil — and surface every hard clash, soft clash, and workflow conflict before a single component reaches the site. Clashes that pass undetected become RFIs, change orders, and schedule delays. Our clash detection services exist to make sure they do not. Our BIM clash detection process runs in Navisworks Manage with discipline-specific tolerance rules, clearance requirements, and priority filters applied before any report is produced. We de-duplicate results, filter out false positives, and deliver a clean, actionable clash report with every issue categorized, ownership assigned, and a resolution path defined. Whether you need standalone clash detection on a single model set, ongoing coordination clash testing across a multi-stage project, or MEP clash detection focused on mechanical and electrical routing through a complex ceiling zone — Eagle BIM runs it accurately, on time, and with full documentation of every decision made.
Critical - Hard Clashes
Two elements physically occupying the same space — a duct through a structural beam, a pipe through a wall without a sleeve. Hard clashes must be resolved before construction. They cannot be worked around on site without significant cost.
Important - Soft Clashes
Elements that do not physically intersect but violate required clearance zones — insufficient maintenance access to equipment, MEP services too close to structural elements, or inadequate ceiling zone depth for the specified finishes.
Constructability - Workflow Clashes
Sequencing and constructability conflicts — elements that are geometrically clear but cannot be installed in the required construction sequence without removing previously installed components or violating trade access requirements.
What We Deliver

Core Clash Detection Service Areas

Every clash detection services engagement covers the full scope — from model intake through final clearance confirmation. Here is what is included.
Hard and Soft Clash Detection
Full hard and soft clash testing across all discipline model pairs using Navisworks Manage. Discipline-specific tolerance rules and clearance requirements applied before each test run. Results filtered, de-duplicated, and categorized before delivery — so every item in the report is actionable.
MEP Clash Detection
Dedicated MEP clash detection covering mechanical ductwork, electrical conduit, plumbing runs, fire suppression, and HVAC systems — tested against architectural and structural models with ceiling zone clearance verification included. Clash ownership assigned to the responsible MEP discipline for every issue.
Federated Model Clash Testing
Multi-discipline federated model assembly in Navisworks — architectural, structural, MEP, and civil models linked with verified shared coordinates. All discipline pair combinations tested systematically. Federated NWD file maintained and updated throughout the coordination program.
Clash Reports and Issue Logs
Structured clash detection and resolution reports with 3D snapshots for every issue, severity ratings, discipline ownership assignments, and resolution status. Delivered in PDF and XLSX at every coordination milestone — formatted to your project standards and BEP reporting requirements.
Clash Resolution Tracking
Every clash is tracked from first detection through final verification. Resolution responsibility is assigned, deadlines are set, model updates are reviewed, and every fixed clash is re-tested before closure. Nothing is marked resolved without confirmation — a complete audit trail is maintained throughout.
Ongoing Coordination Clash Testing
Recurring clash detection services across a project lifecycle — run at agreed coordination milestones as models are updated. Each round re-tests previously resolved clashes and tests new model revisions. Clash counts, resolution rates, and open items tracked across every round in a consolidated project log.
Our Process

How Our Clash Detection Services Work

Every clash detection in construction project follows the same structured process. Clear stages, clear ownership, no surprises.
01
Model Intake
We receive all discipline models, verify shared coordinates and naming conventions, and set up the federated Navisworks environment. Clash rules and clearance tolerances agreed before the first test runs.
02
Clash Testing
Hard and soft clash tests run across all discipline pairs. Results are filtered, de-duplicated, and categorized by severity, discipline, and grid location. Only actionable clashes reach the report.
03
Report Delivery
Structured clash report delivered with 3D snapshots, severity ratings, and ownership assignments. Presented to the coordination team with clear resolution paths and deadlines for every open item.
04
Re-Testing
Models updated by discipline teams. We re-run clash detection to verify all resolutions and identify any new conflicts introduced by model changes. Cycle continues until all clashes are cleared.
05
Final Clearance
Final clash-free confirmation report delivered with complete resolution log, updated NWD, and full audit trail from first detection through final clearance — ready for handover or construction start.

Clash Detection in Construction

Where Clash Detection Services Find the Most Conflicts

The same areas of a building generate the majority of clashes on every project. Our clash detection in construction process focuses testing intensity where conflicts are statistically most likely — ceiling zones, structural penetrations, plant rooms, and riser shafts — so nothing slips through.

68% Ceiling Zone Conflicts
MEP services competing for ceiling zone depth — ducts, pipes, conduit, and sprinklers all fighting for the same 400mm of space above the ceiling.
21% Structural Penetrations
MEP services routing through structural beams, columns, and slabs without coordinated openings or sleeves specified in the structural model.
7% Plant Room Density
Mechanical plant rooms with high MEP density and limited maintenance clearance — equipment, pipework, and electrical switchgear all competing for space.
4% Riser Shafts
Vertical riser shafts with multiple disciplines — plumbing stacks, mechanical risers, electrical busbar trunking — coordinated through structural openings.

Why It Matters

What Proper Clash Detection Services Prevent on Your Project

Every undetected clash that reaches the site costs money, time, and credibility. Here is what our clash detection services consistently prevent.
80%
Fewer Field RFIs
Projects with properly executed clash detection services resolve the vast majority of coordination conflicts before construction — not through costly field RFIs and emergency design changes on site.
Zero
Undetected Hard Clashes
Our process tests every discipline pair combination in every zone of the model. Nothing is assumed clear without being tested — hard clashes do not pass through to the site on our watch.
100%
Documented Resolution
Every clash detected, every resolution confirmed, every re-test passed — fully logged. Your project has a complete clash detection and resolution audit trail ready for any dispute or claim.
4x
Faster Issue Resolution
Issues resolved in a coordinated 3D environment with clear ownership and deadlines are resolved in hours. The same issue discovered on site takes days — with multiple parties, a GC, and usually a change order involved.

FAQs

Frequently Asked Questions

Ask Us Anything →
What is clash detection in BIM and why is it important?
+
Clash detection is the process of identifying geometric conflicts between building disciplines — like a duct passing through a structural beam or a pipe conflicting with a ceiling grid — inside a federated 3D model, before construction begins. Clash detection services typically catch hundreds or thousands of conflicts that would otherwise surface as RFIs, change orders, and field rework. Catching them in the model costs almost nothing; catching them on site costs weeks and serious money.
What is the difference between hard clashes and soft clashes?
+
A hard clash is a physical overlap — two objects occupying the same space, like a beam cutting through a duct. A soft clash is a clearance violation — objects that don't physically touch but violate required separations, such as a pipe within 6 inches of an electrical panel where code requires 36 inches of clearance. Comprehensive clash detection services test for both: hard clashes catch geometric conflicts, soft clashes catch maintenance access, code compliance, and operational issues.
Which software is best for BIM clash detection?
+
Autodesk Navisworks Manage is the industry-standard tool for BIM clash detection — federating models from Revit, AutoCAD, Tekla, and other platforms, then running automated clash tests with Clash Detective. Revizto and Solibri Office are also widely used for issue tracking and BCF exchange. Our clash detection services use Navisworks for testing and Revizto or BIM 360 / ACC for issue management — matched to whatever your team already runs.
How many clashes are normal on a typical project?
+
First-run clash detection on a moderately complex commercial building can flag 500–2,000 clashes — and on a healthcare or lab project, that number can run into the thousands. This is not a sign that something is wrong; it means coordination hasn't started yet. Well-managed clash detection services typically resolve 80–90% of clashes within the first 2–3 coordination cycles, with the remainder narrowed to genuine constructability decisions rather than oversights.
How do you prioritize and group clashes in a Navisworks report?
+
Raw Navisworks output is overwhelming — running everything against everything produces thousands of low-value results. Effective clash detection services apply a clash matrix (rules defining which disciplines test against which) and group clashes by location, type, and trade ownership. Each clash is categorized as critical (must-fix), important (should-fix), or minor (review), and assigned to the responsible trade with a 3D snapshot and resolution note. This converts a clash report from raw data into an actionable issue log.
Who is responsible for resolving the clashes once they are detected?
+
Clash detection services identify and document conflicts; resolution is owned by the responsible trade based on the BIM Execution Plan. Typically MEP reroutes around fixed structural elements, structural avoids fixed architectural openings, and architectural adjusts when ceiling zones need more clearance. The clash detection team facilitates — assigning issues, tracking status, and re-testing after fixes — but the design decision belongs to the discipline making the change.
How long does clash detection take on a typical commercial project?
+
Clash detection itself is fast — running a Navisworks clash test takes minutes. The value-creating work is in setup (clash matrix, selection sets, rules), review (filtering false positives, grouping issues), and the coordination cycles that follow. For a typical commercial project, the first comprehensive clash detection cycle takes 5–10 business days from federated model receipt to delivered clash report; subsequent weekly cycles run 2–3 business days each as issues are progressively cleared.
What deliverables do you provide with clash detection services?
+
Every clash detection cycle includes a Navisworks federated file (.nwd), a structured clash report (PDF or Excel) with categorized issues and 3D snapshots, a BCF or NWD issue export for stakeholder review, an action log assigning issues to trades, and a revision-tracked update from the previous cycle. We also provide coordination meeting minutes and post-meeting issue updates so the project record is fully auditable.
