Upload by Bintang

Clash Detection Matrix Template Guide provides guidance on the concept of clash detection and how to execute the workflow using the correct clash detection matrix. It explains how to identify which elements must be coordinated, then how to complete the required tolerance values in the Clash Detection Matrix Template. The guide references the Navisworks Template Guide for clash reporting and aligns with the BIM Use Processes Design Phase guide for design coordination.

This document relies on the Navisworks Template Guide contained with the Clash Report Template which explains how to report on clash detection; as well as the process for Design Coordination included in the BIM Use Processes Design Phase Guide. Prerequisites: Users should have pre-existing knowledge on the Clash Detection Strategy for the project and Clash Detection Processes in general

FAQs

What is the overall purpose of the Clash Detection Matrix Template Guide?

It guides users on clash detection concepts and on selecting the correct matrix, determining elements to coordinate, and filling tolerance values in the template to complete the process.

How is clash detection defined in this guide?

Clash detection is an iterative process where 3D models are analyzed by project stakeholders to identify and resolve coordination issues between disciplines before construction.

What are the main types of clashes described?

The guide distinguishes hard clashes, where objects intersect beyond the tolerance, and clearance clashes, where objects do not intersect but come closer than the tolerance.
