Top 10 benefits of BIM clash detection, best practices, tools, and more explained in detail.

Building Information Modeling (BIM) is a digital representation of the physical and functional characteristics of a building. It is a powerful tool that enables architects, engineers, contractors, and other stakeholders to collaborate and share information throughout the construction process. One of the most significant advantages of BIM is its clash detection feature.

The absence of clash detection in a construction project can have several negative impacts, including:

  1. Increased Rework: Clash detection allows the identification of potential issues between different building systems, such as structural, mechanical, electrical, plumbing, and fire protection. Without clash detection, these issues may only be identified during construction, leading to rework, which is costly and time-consuming
  2. Cost Overruns: When clashes are not detected early in the design process, they can lead to significant delays and additional costs during construction. Rework, reordering of materials, and additional labor expenses are just a few examples of the costs that can arise from a lack of clash detection
  3. Schedule Delays: Unresolved clashes can cause construction delays, as the construction process may need to be paused until the issues are resolved. In some cases, redesign and additional review of plans may be necessary to address the clashes, which can significantly impact the project timeline
  4. Safety Risks: Clashes can lead to safety risks during the construction process or even after the completion of the project. For example, an unresolved clash between the electrical and mechanical systems can lead to a fire or explosion, causing injury to workers and damage to the building
  5. Quality Issues: The absence of clash detection can result in design conflicts that compromise the quality of the finished building. For instance, a poorly coordinated structural design may result in structural instability, leading to cracks or even collapse

The absence of clash detection can result in significant impacts on a construction project, including increased rework, cost overruns, schedule delays, safety risks, and quality issues. Therefore, the use of clash detection software is crucial to identify and resolve potential clashes during the design process and ensure a successful construction project.

In this blog, we will discuss the top 10 advantages of BIM clash detection.
  1. Early Detection of Errors: BIM clash detection allows errors to be identified in the design phase before construction begins. This early detection can save time and money by avoiding costly changes and delays during construction.
  2. Collaboration: BIM clash detection promotes collaboration among project stakeholders by providing a centralized platform to share information. This enables architects, engineers, and contractors to work together to identify and resolve potential conflicts
  3. Efficiency: With BIM clash detection, potential clashes can be identified and resolved quickly, saving time and reducing the risk of rework. This can lead to increased efficiency and improved project timelines
  4. Communication: BIM clash detection enables project stakeholders to communicate more effectively by providing visual representations of potential conflicts. This can lead to a better understanding of the project and a more streamlined decision-making process
  5. Quality: BIM clash detection can help ensure that the final product meets the highest quality standards. By identifying and resolving conflicts early, the final product is more likely to be error-free
  6. Costs: BIM clash detection can help reduce costs by identifying and resolving potential conflicts before construction begins. This can lead to a reduction in rework, change orders, and delays, ultimately saving the project budget
  7. Safety: BIM clash detection can help identify potential safety hazards before construction begins. This can lead to improved safety conditions for workers and the public
  8. Sustainability: BIM clash detection can help improve sustainability by identifying and resolving conflicts related to energy efficiency, material use, and other sustainability-related factors
  9. Decision Making: BIM clash detection provides project stakeholders with the information they need to make informed decisions. By providing visual representations of potential conflicts, stakeholders can make decisions based on accurate information
  10. Competitive Advantage: BIM clash detection can provide a competitive advantage by improving project timelines, quality, and efficiency. This can lead to increased client satisfaction and repeat business

Based on a study by Dodge Data and Analytics, 40% of rework in construction is due to design conflicts or clashes.

Building Information Modeling (BIM) has become a game-changer for the construction industry. It enables teams to visualize, simulate, and optimize building design, construction, and operations. Clash detection is an essential feature of BIM that allows designers, engineers, and contractors to identify and resolve conflicts or clashes in the design phase before construction begins.

Different types of clashes

BIM is intended to improve the coordination and collaboration between all parties involved in a construction project. However, despite the advantages of using BIM, there can be clashes or conflicts that arise. Here are some common types of BIM clashes:

  1. Structural and architectural clashes: This type of clash occurs when the structural elements and architectural features of a building are not properly coordinated. For example, the design of a beam may interfere with a window or door opening, or a load-bearing wall may conflict with an interior design feature.
  2. Mechanical and electrical clashes: This type of clash occurs when the mechanical (HVAC) and electrical systems are not properly coordinated. For example, an HVAC duct may interfere with an electrical conduit or a plumbing pipe may conflict with a ductwork path
  3. Plumbing clashes: This type of clash occurs when the plumbing system is not properly coordinated. For example, a plumbing pipe may interfere with a structural element or a plumbing fixture may conflict with a ceiling or wall
  4. Fire protection clashes: This type of clash occurs when the fire protection system is not properly coordinated. For example, a fire sprinkler head may interfere with a light fixture or a fire alarm pull station may conflict with a door or window
  5. Site clashes: This type of clash occurs when the building design conflicts with the site’s constraints. For example, a building may be designed with a large footprint that encroaches on setbacks or zoning requirements, or a proposed building height may exceed local height restrictions

BIM clashes can cause delays, rework, and increased costs in a construction project. However, by using BIM clash detection software, potential clashes can be identified early in the design process, allowing for proactive resolution before construction begins.

Breakdown of the BIM clash detection process
  1. Model Creation: In the initial stage, the 3D BIM model of the building or infrastructure is created using BIM software. This model includes information about the building’s structure, systems, and components, such as walls, floors, roofs, HVAC, electrical, plumbing, and fire protection systems
  2. Clash Detection: Once the model is created, the clash detection process begins. The software analyses the model to identify potential interferences between various building components, such as pipes intersecting with walls or ductwork running into beams
  3. Clash Reports: After identifying the clashes, the software generates clash reports that provide information about the type and location of the clash. These reports help stakeholders understand the severity of the clash and the potential impact on the project’s timeline and budget
  4. Collaboration: Once the clashes are identified, stakeholders such as architects, engineers, and contractors collaborate to resolve them. This may involve modifying the design, adjusting the placement of components, or selecting alternative materials
  5. Re-Clash Detection: Once the clashes are resolved, the model is re-evaluated using the clash detection process to ensure that all the interferences have been resolved. This step may be repeated several times until all the clashes are eliminated
Best Practices to Resolve Clashes
  1. Set up clash detection rules: Before running clash detection tests, it’s essential to define the rules and parameters to identify clashes accurately. Setting up rules helps in avoiding false positives and streamlines the resolution process
  2. Collaborate and communicate: Clash detection is not a one-person job. It’s crucial to involve all stakeholders, including designers, engineers, contractors, and clients, in the resolution process. Collaborating and communicating openly can help in resolving clashes quickly and efficiently
  3. Prioritize clashes: Not all clashes are created equal. Prioritizing clashes based on their impact on cost, safety, and schedule can help in resolving critical issues first
  4. Use visuals: 3D visualization tools are essential for clash resolution. Visualizing clashes in 3D helps in understanding the issue better and coming up with solutions
  5. Document and track: Documenting and tracking clashes and their resolutions is essential to ensure that they don’t reoccur. Keeping a record of clashes can also help in identifying trends and improving the clash detection process

BIM clash detection tools and practices are critical to ensure a successful construction project. Using the right tools and following best practices can help in identifying and resolving clashes efficiently, saving time, and cost, and minimizing errors.

Based on a survey by McGraw Hill Construction, 61% of construction professionals using BIM witnessed a reduction in project errors.

What are the viewpoints in clash detection?

In BIM clash detection, viewpoints refer to specific camera views or perspectives of the 3D model that are used to analyze and resolve clashes or conflicts between building elements. Viewpoints are important in clash detection because they allow users to see the model from different angles and identify potential clashes or collisions that may not be visible from other viewpoints.

Viewpoints are created by positioning the camera in the 3D model and setting the viewing angle, elevation, and field of view. Different viewpoints can be created for each clash test to ensure that all possible clashes are detected and resolved.

For example, a clash detection analysis between a structural beam and mechanical ductwork may require several viewpoints to identify all possible clashes, such as a top-down view, a side view, and a 3D perspective view. Each viewpoint provides a different perspective and helps to identify clashes that may be missed from other viewpoints.

Viewpoints can also be used to communicate clash detection results to project stakeholders. By sharing 3D models and viewpoints, stakeholders can better understand the nature and severity of the clashes and provide feedback on the resolution process.

Viewpoints are essential in BIM clash detection as they help to identify and resolve clashes by providing different perspectives and angles of the 3D model. They also facilitate communication and collaboration among project stakeholders by providing a clear and comprehensive view of the clash detection analysis.

According to McGraw Hill Construction, professionals utilizing BIM processes and tools witnessed a 51% reduction in rework.
