BIM Clash Detection Services for Coordinated Construction Models
Optimar Precon helps contractors, architects, engineers, and BIM teams identify hard clashes, soft clashes, clearance issues, and model coordination problems before construction begins. Our experts use Revit, Navisworks, BIM 360, and federated model review workflows to reduce rework, delays, and site conflicts.
What are BIM clash detection services?
BIM clash detection services identify design conflicts inside a federated building model before construction begins. These conflicts may include physical overlaps, clearance issues, access problems, and coordination gaps between architectural, structural, mechanical, electrical, plumbing, and fire protection systems.
Physical conflicts where two model elements occupy the same space, such as a duct crossing through a beam or pipework clashing with structure.
Spacing or tolerance issues where elements do not have enough clearance for installation, maintenance, access, or code related requirements.
Access zone conflicts around equipment, doors, plant rooms, ceiling spaces, service routes, and areas that require operational clearance.
Expert Clash Detection That Improves Coordination Before Site Work Begins
Optimar Precon supports contractors, architects, engineers, and BIM coordination teams with structured clash detection and model review. Our BIM specialists use tools such as Navisworks Manage, Autodesk Revit, and BIM 360 to review architectural, structural, and MEP models before construction.
- Identify hard, soft, and clearance clashes before construction drawings are finalized.
- Review architectural, structural, MEP, HVAC, plumbing, fire protection, and electrical model conflicts.
- Generate clear clash reports with issue IDs, screenshots, viewpoints, locations, and responsibility notes.
- Support coordination meetings, issue tracking, model validation, and final clash closeout.
Our BIM Clash Detection Service Offerings
We review federated BIM models, detect conflicts across disciplines, categorize issues, and deliver clear clash reports that help project teams resolve coordination problems before they reach the construction site.

Model Validation and Final Check
After coordination updates, we review the revised model to confirm that major clashes have been closed and the model is ready for the next project stage.

Contact NowHow Our BIM Clash Detection Process Works
Our clash detection workflow is structured to help project teams identify, review, assign, and close coordination issues before they create rework on site.
Model Collection
We collect Revit files, IFC files, Navisworks files, drawings, specifications, scope notes, and discipline models from the project team.
Federated Model Setup
Architectural, structural, and MEP models are combined into a federated model environment for coordinated review and clash testing.
Clash Test Configuration
We define clash test rules for hard clashes, soft clashes, clearance requirements, MEP systems, structural elements, and spatial zones.
Issue Detection and Grouping
Detected clashes are grouped by discipline, priority, location, system type, responsibility, and impact so the project team can act quickly.
Clash Report Delivery
We prepare clear clash reports with screenshots, viewpoints, issue IDs, locations, comments, and coordination notes for review meetings.
Resolution and Validation
After model updates, we review revised files and validate whether critical clashes have been resolved before final coordination closeout.
Clash Detection Support Built for Real Construction Coordination
Optimar Precon helps project teams move from uncoordinated BIM models to clear, trackable, and construction-ready coordination outputs. Our team understands how architectural, structural, and MEP systems interact, so every clash report is prepared for practical review, not just software output.
We review architectural, structural, mechanical, electrical, plumbing, HVAC, and fire protection models with proper discipline separation and coordination logic.
Issues are grouped by severity, location, trade, and resolution priority so your coordination team can focus on the clashes that matter most.
Our reports include screenshots, viewpoints, issue IDs, model locations, comments, and responsibility notes to support coordination meetings and follow-up actions.
We support teams working across the USA, UK, Ireland, UAE, Saudi Arabia, Canada, and other construction markets with structured BIM workflows.
Our offshore BIM specialists help your internal team manage peak coordination workloads without adding permanent hiring pressure.
After updates, we recheck revised models to confirm that major coordination issues have been resolved before the next project milestone.

Typical Clash Detection Deliverables
BIM Clash Detection FAQs
What are clash detection services in BIM?
Clash detection services identify conflicts inside BIM models before construction starts. These conflicts can include physical overlaps, clearance problems, access issues, and coordination gaps between architectural, structural, mechanical, electrical, plumbing, HVAC, and fire protection systems.
What is the difference between hard clash, soft clash and clearance clash?
A hard clash is a physical overlap between two model elements. A soft clash is a spacing or tolerance issue. A clearance clash happens when required access or maintenance space around equipment, services, doors, shafts, or plant rooms is blocked.
When should BIM clash detection be performed?
BIM clash detection should be performed during the design coordination phase and repeated after major model updates. Running clash detection before construction drawings are finalized helps reduce site conflicts, RFIs, delays, and rework.
Which tools are used for clash detection?
Common tools include Navisworks Manage, Autodesk Revit, BIM 360, Autodesk Construction Cloud, and issue tracking formats such as BCF, Excel logs, PDF reports, and Navisworks viewpoints.
What information is included in a clash report?
A clash report usually includes issue IDs, screenshots, viewpoints, location references, clash type, trade responsibility, discipline tags, comments, priority level, and resolution status.
Can Optimar Precon support ongoing BIM coordination?
Yes. Optimar Precon can support one-time clash detection, repeated coordination reviews, revised model validation, and ongoing offshore BIM coordination support for contractors, architects, engineers, and project teams.
