Clash detection is a crucial process in Building Information Modeling (BIM) that identifies potential conflicts, interferences, or clashes between various building components or systems before construction starts. This vital step in the BIM workflow helps pinpoint and resolve issues early, reducing costly rework, delays, and safety hazards during construction.

In BIMology, clash detection is executed using Navisworks Manage that analyzes 3D models from different disciplines, such as architectural, structural, and MEP (Mechanical, Electrical, and Plumbing) systems. The software compares these models to identify any overlaps, intersections, or interferences among the components.

The client simply uploads the models to BIMology, and clarifies the required clash detection rules and tolerances to BIMology’s team, who in return will be providing a clash detection report based on the requirements.

The clash detection process generally involves the following steps:

1. Model integration: Combining or federating 3D models from different disciplines into a single coordinated model for comprehensive analysis.

2. Clash detection rules: Applying predefined rules or settings to identify specific types of clashes, such as hard clashes (physical interferences) and soft clashes (clearance violations or coordination issues).

3. Clash identification: Analyzing the integrated model to identify potential clashes based on the defined rules.

4. Clash reporting: Documenting and presenting identified clashes in a report, often with visual aids like clash clouds or markers to facilitate review and resolution.

Clash detection is an integral part of the BIM process, contributing to the overall efficiency, cost-effectiveness, and quality of construction projects.
