Clash detection software is a digital tool that identifies conflicts between different building systems before construction begins. This type of software is becoming increasingly important as AEC projects become more complex, with tighter deadlines and greater cost pressures, and traditional coordination methods can no longer keep up.
By spotting issues early in the design phase, clash detection software helps teams avoid costly onsite mistakes, protect project timelines, and safeguard their reputations, making it an essential part of modern project delivery.
At Interscale, we’ve rolled out full BIM management service around Australia and all anchored by robust clash detection tools. Those lessons underpin the detail that follows. We hope this gives you a practical roadmap for choosing and using the right platform.
What is Clash Detection Software?
Clash detection software automates the identification, inspection, and reporting of interferences, or clashes, within digital project models. By catching these issues during design, clash detection tools prevent costly on-site fixes.
Whether it’s a hard clash (two objects colliding) or a soft clash (insufficient clearance), clash detection tools deliver detailed reports, slashing risks, costs, and delays. Making it an essential part of Building Information Modeling (BIM) and Virtual Design and Construction (VDC).
What is an Example of Clash Detection?
These examples reflect the main types of clash detection in BIM, commonly grouped as hard, soft, and workflow clashes. In practice, clashes often appear in construction as:
- Hard Clash: A big ventilation duct designed to slice right through a main support beam. That’s a classic hard clash. If it wasn’t spotted early using BIM clash detection software, it would physically stop installation and mess with the building’s structure.
- Soft Clash (or Clearance Clash): an electrical panel modelled too snug against a wall, leaving no room for a spark to safely open the door later for checks. Or maybe a pipe running too close under equipment, blocking future repair access. Model checking tools are great at finding these.
- Workflow/4D Clash: You are scheduling interior wall installation before the plumbing or electrics inside those walls are done. Or planning a crane delivery to an area where the ground prep hasn’t been finished as per the schedule.
Best Clash Detection Software 2025
Choosing the best clash detection software hinges on your project’s needs—budget, workflow, and scale. Here are some of the options available.
Navisworks Manage
Clash detection in Navisworks-based projects is rarely a hassle. All because Navisworks Manage is a powerhouse dedicated to clash detection. It pulls models from Revit, Tekla, and more into one environment, running precise hard and soft clash checks. Its reporting tools let teams track and resolve issues efficiently. Perfect for detailed coordination, it’s a go-to for Australian AEC projects.
Solibri
Solibri Model Checker goes beyond clash detection software, offering top-tier model checking. Its rule-based engine validates models against codes, standards, and project specs, catching clashes and data gaps. Ideal for OpenBIM projects, Solibri ensures quality and compliance. Australian firms rely on it for rigorous BIM coordination.
Revizto
Revizto redefines BIM clash detection software with its cloud-based collaboration platform. Its Clash Automation tool groups clashes smartly, while the Issue Tracker ties conflicts to 2D/3D models for real-time resolution. With smooth visuals and mobile access, it’s built for team synergy. Australian AEC firms love their streamlined BIM coordination.
ClashMEP in Revit
ClashMEP, a Revit add-in, delivers real-time clash detection during MEP design. It automatically flags conflicts such as duct–pipe intersections as you model, which reduces errors before they spread. Designers benefit from faster iterations, as there is no need to export models to Navisworks for every basic check.
This capability makes Revit clash detection an integral part of everyday modelling, embedding clash prevention directly in the design process. By reducing rework and improving model quality, it strengthens overall BIM coordination.
For local procurement, you can buy Revit license through Interscale as an Autodesk authorised partner in Australia.
Autodesk Construction Cloud
Autodesk Construction Cloud (ACC) offers cloud-based clash detection software via its Model Coordination module. Models uploaded to Autodesk Docs trigger automatic clash checks, with results grouped for review. Integrated issue tracking keeps teams aligned. It’s user-friendly, requiring no specialized software for basic tasks. Many AEC firms value their centralized BIM coordination. ACC streamlines clash detection in construction, ensuring clash-free designs and efficient project delivery across the board.
BIM Track
BIM Track is a cloud-based hub built for AEC teams who live and breathe BIM coordination. It won’t run the clash checks itself. That job still sits with your clash detection software of choice, whether that’s Navisworks, Solibri, or a Revit add-in. BIM Track plugs into all those tools without fuss. Every clash those programs uncover funnels straight into one shared dashboard, where the issue appears in full 2D or 3D context, can be assigned to the right person, discussed, and ticked off once resolved. And complete with clear metrics for who did what and when.
Bentley Navigator
Bentley Navigator excels in Bentley’s ecosystem, handling large infrastructure models with ease. It detects hard and soft clashes, supports 4D scheduling, and integrates with ProjectWise for seamless BIM coordination. Australian infrastructure projects rely on it for robust clash detection in construction. With strong visualization and analysis tools, Navigator ensures clash-free designs in complex workflows, making it a top choice for BIM clash detection software in Bentley-centric projects.

How BIM clash detection work?
BIM clash detection works through a structured process to ensure model accuracy. It systematically identifies conflicts before they become on-site problems. The process typically involves these key steps:
- Aggregate models into a shared space and align coordinates.
- Clean links and naming, then publish to a controlled folder.
- Select discipline sets for tests and define tolerances.
- Configure rule sets in model checking tools, including clearance rules.
- Run test batches on schedule and auto-group repeated issues.
- Classify results by severity and location for fast triage.
- Assign issues to owners with due dates and viewpoints.
- Sync status to a central tracker and re-run after fixes.
- Report KPIs like open rate, mean time to close, and reopens.
- Lock sign-off states for audit and archive approved snapshots.
Benefits of Using Clash Detection Software in BIM
The benefits of using clash detection software in BIM focus on reliable project outcomes. Automated detection reduces design-stage oversights, which directly lowers costly site rework. Consistent testing also improves schedule stability and protects budget margins.
For BIM teams, dedicated model checking software enhances data integrity and compliance with project standards. Clash results are traceable to accountable owners, and meeting time is reduced as coordination becomes evidence-driven. Cloud-based systems further strengthen collaboration by synchronising model versions and clash logs across multiple locations.
Designers can run checks natively within authoring tools, which stops errors before models are exported. Coordinators then aggregate models, apply structured rulesets, and manage issue close-out across disciplines. This layered workflow ensures conflicts are resolved systematically and recorded for future audits.
Is Clash Detection Driven by AI?
Most clash detection software relies on geometric algorithms and user-defined rules, not true AI. It compares model coordinates to flag overlaps or clearance issues, in precise, not predictive. But AI’s creeping in. Emerging tools use machine learning for smarter clash prioritisation or suggesting fixes based on past projects.
While BIM clash detection software shows traditional tools dominate, AI could soon enhance model checking, making processes sharper. For now, software like Navisworks or Solibri delivers robust, rule-based BIM clash detection in construction.
Is There AI Detection Software?
AI detection software isn’t standard yet, but it’s on the horizon. Current clash detection tools lean on rules, not AI. Still, AI is being explored to classify clashes, suggest resolutions, or predict issues based on historical data. Think automated prioritization or spotting high-risk areas in designs. While not fully AI-driven, platforms like Revizto are starting to integrate smarter features.
