What is BIM Clash Detection?

Clash detection is an integral part of Building Information Modeling (BIM). BIM clash detection finds and resolves clashes between two or more construction models within a virtual setting.

In essence, BIM clash detection scrutinizes different design components like structural elements, HVAC systems, and electrical conduits to identify any overlaps or interference within a virtual model. This highly detailed analysis is invaluable for project managers and structural engineers, allowing them to resolve issues before they escalate into costly and time-consuming problems during construction.

Using BIM clash detection tools like the Solibri Model Checker, teams can detect clashes in real time, reducing material waste and repetitive tasks while significantly improving communication and coordination. So, adopting clash detection processes in the pre-construction phases is necessary for any successful construction project.

What are the major types of Clashes?

To optimize BIM clash detection, it is essential to understand the different types of clashes that can arise in a construction project. They are not all the same and have varying impacts on the model and resolution approaches. However, there are three primary types of clashes to be aware of: hard clashes, soft clashes, and workflow clashes. Each type presents unique challenges and requires specific strategies for effective management.

Hard Clashes

A hard clash occurs when two components, like structural beams and HVAC ducts or plumbing pipes and electrical conduits, occupy the same physical space in a BIM model. These clashes are the easiest to detect but can be incredibly costly if overlooked, leading to significant rework during the construction phase. Effective BIM clash detection tools and real-time model reviews help project managers and structural engineers resolve these conflicts early, ensuring smoother workflows and minimizing material waste.

Soft Clashes

A soft clash, or clearance clash, arises when building elements lack enough space for efficient operation and safety. Unlike physical overlaps, soft clashes involve indirect interference, such as insufficient buffer space for maintenance access. In MEP services, these clashes can lead to significant safety and functionality issues, including maintenance challenges and potential hazards like electrical short circuits. Many BIM professionals use effective BIM clash detection tools, like the Solibri Model Checker, to resolve these issues early, enabling timely resolutions and enhancing overall project coordination.

Workflow Clashes

A Workflow Clash, also known as a 4D clash, occurs when scheduling conflicts disrupt project timelines, leading to work stoppages, rework, and delays. Whether it’s the misalignment of electrical conduit installation with concrete pouring or premature equipment delivery, these clashes can significantly hinder on-site productivity. Leveraging BIM technology for clash detection and resolution ensures efficient scheduling and sequencing, ultimately enhancing overall project efficiency and communication among stakeholders.

Key Benefits of BIM Clash Detection:

Time and Cost Savings: Saves time and money by resolving clashes early

Enhanced Collaboration: Promotes better collaboration, communication and teamwork among different disciplines.

Reduced Material Waste: Precise planning minimizes unnecessary waste.

Improved Safety: Mitigates risks such as on-site incidents by preventing unexpected problems.

Efficient Scheduling: Ensures smoother workflow, faster project completion, and improves project scheduling and installation efficiency.

Small companies and those with BIM are likely to face fewer challenges in the integration process.
Clash detection is most beneficial during the design phase of a project, ensuring designs meet specified parameters. Its use is limited in the planning phase due to the need for a completed BIM model and is less effective post-construction as it does not apply to existing structures. Essentially, while valuable, its utility is primarily during specific project stages.
Keep stakeholders updated on clash detection and resolution, starting as soon as the BIM model is ready. Document all findings and resolutions, analyze patterns in recurring clashes to target root causes, and use clear guidelines to differentiate major from minor issues. Choose software with strong integration capabilities to simplify and enhance the detection process.
