What is BIM Clash Coordination?
BIM Clash Coordination (also called Clash Detection) is the process of identifying and resolving design conflicts between different building systems — architectural, structural, and MEP — before construction begins. Using tools like Autodesk Navisworks, BIM coordinators detect where elements physically intersect (hard clashes), come too close (soft clashes), or conflict in scheduling (workflow clashes). This process reduces construction rework by up to 40% and prevents costly on-site changes. BIM Design LLC provides expert clash coordination services across Qatar, UAE, and Saudi Arabia.

❓ Frequently Asked Questions About BIM Clash Coordination

What types of BIM clashes are there? ▸
There are three types: (1) Hard clashes — physical intersections where elements occupy the same space (e.g., a duct running through a beam), (2) Soft clashes — clearance violations where elements are too close for maintenance access or code compliance, and (3) Workflow clashes — scheduling conflicts where construction sequences would create physical conflicts.
How much money does clash detection save? ▸
Studies show BIM clash detection reduces construction rework by 30-40% and can save 5-10% of total project costs. For a $50M project, that translates to $2.5-5M in savings. The ROI of clash coordination is typically 10:1 or higher, making it one of the most cost-effective BIM services available.
What tools are used for BIM clash detection? ▸
The industry standard is Autodesk Navisworks Manage for automated clash detection. BIM Design LLC also uses Solibri for model checking and rule-based validation. Models from Revit (architecture, structure, MEP) are federated in Navisworks where automated clash tests identify conflicts across all disciplines.
When should clash coordination start on a project? ▸
Clash coordination should begin during the design development phase (DD) and continue through construction documentation (CD). Early detection — ideally at 60-80% design completion — provides the most value, as changes are significantly cheaper to make in the model than on the construction site.
