How to Use Clash Avoidance vs. Clash Detection Strategies in Your BIM Workflows

Building Information Modeling (BIM) has revolutionized the architecture, engineering, and construction industries by providing a collaborative and data-driven approach to project planning and execution. One of the critical aspects of BIM is clash avoidance, which plays a vital role in ensuring the smooth coordination of various systems in a building project. In this article, we will explore how BIM clash avoidance techniques work and why they are essential in modern construction workflows.

How does BIM Clash Avoidance work?

Clash avoidance techniques take into account the order in which elements and components are connected and functionally installed in the model so that all systems can be routed through a building without generating thousands of clashes that would later result in rework and delays.

In order to avoid conflicts when using BIM, two crucial factors must be used:

1. System Priority Structure: How the BIM model is put together in order

Clash avoidance in a BIM workflow depends on the priority structure. You can prevent potential conflicts with other project components by being aware of which elements need to be addressed first and in what order. For instance, the electrician can work without having to move the ductwork if more flexible electrical routing is installed after longer mechanical duct runs. The same can be said for many aspects of architecture. When mechanical and electrical systems are installed before walls, there will not be any conflicts when the other tradesmen arrive to finish their work.

2. Cloud Collaboration Tools: Information sharing is made possible by cloud collaboration software, which is quick and simple.

For the purpose of preventing BIM clashes, cloud-based collaboration software is also crucial. Designers and engineers can track their own elements, manage updates, and view the entire system as a whole using BIM software for collaboration. This makes it simpler to identify and prevent potential conflicts before they materialize in the virtual world. SJS Global offers BIM design services, which means they use special technology to make detailed 3D models for different projects. These models help people work together better and make construction easier. SJS Global can help with designing buildings, making sure they are strong, and planning electrical and plumbing systems.

Why Is Avoiding Clashes Important?

Any building design process that avoids conflicts can help cut down on costly rework and delays brought on by poor design decisions or poor team communication. Teams can collaborate to ensure that all models are current, communicate updates quickly and effectively, and prevent potential clashes in the virtual world before they turn into expensive physical issues down the road by using BIM clash avoidance techniques. The end result is a fully coordinated BIM model that demonstrates all components, their connections, and how they work together, ultimately saving time, money, and resources.

How Do You Put Clash Avoidance Techniques Into Practice?

The process of putting clash avoidance strategies into practice calls for careful planning and team coordination. Making use of BIM tools can:

1. Identify the proper components and systems.

Before beginning any project, it is essential to identify the different components and systems involved. This will enable the team to understand the complexity of the project and the potential areas where clashes may occur.

2. Charge the modeling teams with certain duties.

Assigning specific duties to modeling teams ensures that each element is properly accounted for and that the team members take responsibility for their respective areas. This accountability helps prevent clashes during the modeling phase.

3. Order the tasks to prevent conflicts.

By prioritizing the tasks and following a logical sequence, the chances of clashes are minimized. Understanding the dependencies between various elements and systems is critical in preventing conflicts during the construction phase.

4. Monitor results and contrast alterations.

Regularly monitoring the clash detection reports and analyzing potential clashes helps the team to make necessary alterations and adjustments in the model. This proactive approach ensures that conflicts are resolved before they impact the construction phase.

Streamlining the Process with SJS Global Solutions

The complex process of designing and building a structure can be streamlined with SJS Global Solutions, as they possess a team of experts that can further make the process easier and more comprehensible than ever. Workshops on pull planning can assist in organizing the order in which the project’s systems should be installed. This makes it simpler to prevent collisions by enabling a better understanding of what elements go where and when. A team project should always have a plan that everyone on the team can follow. Pull planning is a crucial collaborative strategy for understanding the precise order in which each element will be placed. It brings together many of the team’s opinions into one plan.


In conclusion, by incorporating BIM clash avoidance techniques into your workflow, you will have more control over a project’s schedule, budget, safety requirements, and quality control standards—all of which are essential for completing successful construction projects on time and within your projected spending limit! Teams can work cooperatively and proactively identify potential clashes when a well-organized clash avoidance strategy is in place, preventing costly virtual or actual problems from occurring. SJS Global is a company that offers comprehensive Building Information Modeling (BIM) services to clients in the construction industry. Their BIM services include 3D modeling, clash detection, quantity takeoff, construction sequencing, and more.


What is BIM clash avoidance?

BIM clash avoidance is a process that involves identifying and preventing clashes between different elements and systems in a building project using BIM software and collaborative strategies.

How does clash avoidance differ from clash detection?

Clash avoidance focuses on preventing clashes before they occur, whereas clash detection identifies clashes after the model is created, requiring rework and causing delays.

What are the benefits of BIM clash avoidance?

BIM clash avoidance helps save time, money, and resources by preventing costly conflicts during the construction phase, leading to smoother project execution.

How can cloud collaboration tools aid in clash avoidance?

Cloud collaboration tools enable designers and engineers to share information and updates quickly, allowing them to identify and resolve potential clashes in the virtual model.

Can clash avoidance be implemented in all types of construction projects?

Yes, clash avoidance techniques can be applied to various construction projects, regardless of their size or complexity, to ensure a coordinated and efficient building process. Learn More
