A “clash” happens when elements in the design take up the same space. In BIM, clash detection is the process of identifying where and how those elements are interfering with each other. Clash detection is crucial in detecting clashes before construction begins.
Traditional methods consisted of on-site coordination or manually overlapping designs on paper, which resulted in delayed deadlines, escalating budgets, and frustrating re-work. (Circling back to that time is money concept). Utilizing BIM for clash detection exposes all clashes in real-time before construction begins.
A full BIM model will consist of individual 3D models from each trade linked into your trade’s 3D model. Clash detection analyses each model against one another to verify that an element in one model does not interfere with another model’s component.
BIM clash detection efficiently examines designs, identifies clashes, and produces clash reports during the engineering and design phase. The benefits of clash detection include but are not limited to:
· Verifying structural integrity
· Reducing the risk of human error
· Preventing scheduling nightmares
· Ensuring the model fulfills safety requirements
· Avoiding late-stage redesign
The modern clash detection workflow utilizing BIM makes it easy for teams to share and collaborate on the same project. Clash detection ensures efficient knowledge transfer, resulting in streamlined coordination between all teams in the design and construction process.
In conclusion, BIM clash detection has revolutionized the design process by giving all trades the ability to visualize, analyze, and correct clashes in advance. In addition, clash detection has made the lives of architects more painless by allowing them to control and supervise various elements without having to compromise at the last minute for construction completion.
