BIM Clash Detection Services Australia
Industry: Project Management Solutions Location: Australia
The challenges
- The construction work had already started, BIM adoption at a later stage during the project is challenging.
- The turnaround time was another challenge, and detailed BIM had to be developed and delivered within an almost unreasonable deadline.
- Additionally, the team also had to understand and deliver BIM with Level of detail 500, as per the Australian standards.
- The building information model had to be developed to support the client right through the facility management phase, and details for all disciplines including MEP, architecture and structure had to be integrated.
- The project was taken up when the construction had already started and interdisciplinary clash detection and construction simulation along with material take off, scheduling etc was quite a challenge.
Technology & software used
- Autodesk Revit Architecture
- Autodesk Revit Structure
- Autodesk Revit MEP
- Autodesk NavisWorks
- The client, a reputed company from Australia, contacted Australian Design and Drafting Services for a University Hospital building project. The construction work had already started and the client wanted BIM with LOD 500, as per AIA standards, across MEP, architectural and structural disciplines. This construction documentation was intended to not only make the process of construction efficient but also to enable a smooth and streamlined facility management once the building gets occupied.
Outcome & benefits
- As the project delivery was on time and the most suitable to carry out construction flawlessly, the client – main contractor for this project, finished construction on time as per tender deadline and as desired.
- Liabilities, risks due to clashes and hence rework during the construction phase reduced, in addition to reduction in wastage of materials, manpower and time. Hence client saved money on the project and thus enjoyed better ROI.

How our BIM clash detection process runs
BIM clash detection only helps if it produces decisions, not just clash counts. Our process federates the discipline models in Navisworks, runs structured test batteries — structure versus services, services versus services, everything versus maintenance access zones — and filters the raw results down to genuine coordination issues before anyone sees a report. Each real clash is assigned, tracked and closed through resolution cycles, with the model updated evidence of the fix rather than a promise of one.
Clash reporting that teams actually use
Reports group clashes by zone and responsible discipline with viewpoint images and locations, so the services engineer opens the report and knows exactly which duct moves. We run the coordination meetings where clients want them chaired, or feed the tracked register into the client’s own process. The metric that matters is clashes reaching site: on well-run coordination cycles it approaches zero, and the RFIs and rework that vanish with it fund the coordination effort several times over.
We provide clash detection as part of full BIM scope or as an independent coordination service across models authored by others — often the more valuable position, since an independent coordinator has no discipline to protect.
Timing determines value in coordination: clash detection run at fifty percent design development steers the design cheaply, while the same exercise at tender stage merely documents the fight ahead. We advise clients to schedule the first federated review as soon as all disciplines have geometry in the right place — earlier than most BIM execution plans specify — because the cheapest clash resolution is the one that happens while the design is still soft.
