Clash Detection Software and BIM

Table of Contents

The definition of clash detection

Clash detection is an essential part of a BIM (Building Information Modeling) process, which is a process of creating sophisticated models that consist of several different models from various engineering and design disciplines.

Independent models are created by MEP engineers, architects, structural engineers, and others, and these models are then connected and integrated to create a BIM model, which is precisely where clash detection comes in.

As the name suggests, the primary purpose of BIM clash detection is to identify specific places where different models may overlap, creating compatibility problems. It is much easier and less costly to solve these problems in the design stage than when the actual building is nearly complete.

The addition of advanced 3D modeling to the construction process reduces or eliminates problems caused by incompatible or clashing models from different experts. The correct implementation and use of clash detection software can also greatly reduce the amount of potentially expensive rework that may happen on-site. It is safe to say that clash detection BIM is an invaluable instrument that can save much money, time, and effort in any construction project.

Clash detection in a modern environment

Engineering design is quite a sophisticated field that demands effective cooperation from multiple stakeholders to achieve the intended results. In the modern day, these stakeholders are architects, vendors, engineers, and suppliers, who are basically all present in any construction project by default.

The existence of various stakeholders sets the complexity bar at a substantial level, and there is also the fact that every project has a time limit. This means that all stakeholders must achieve a certain level of cooperation for the execution of the entire construction project to be timely and precise.

This is where clash detection comes in, offering the ability to detect contradictions between different models as early as the design phase. Every single clash eliminated during the design phase means one less potential problem that might result in a multi-level design change, project delay, or budget increase.

Benefits of clash detection

BIM clash detection offers several advantages, the most important of which are:

  • Easier sequencing and/or scheduling
  • Accurate estimates for the entire construction phase, leading to fewer unforeseen issues
  • Faster construction and higher productivity
  • Fewer errors in all stages of the construction project
  • Less risk, lower overall cost, and drastically decreased material waste

The process of clash detection

The actual process of detecting (and resolving) clashes can vary quite a lot depending on what is considered part of the process. Some users claim that elements such as “development of the original BIM model” or “repeated clash detection analyses” are outside of the clash detection process, while others include them.

As such, our version of the clash detection process is somewhere in between these different viewpoints and includes seven different steps:

  1. Creation of the model. This is the original BIM or CAD model that will be used as the baseline for clash detection. It should represent all the different elements of the project, including structural parts, architectural design choices, and all kinds of essential components.
  2. Integration of models. BIM software is used in this step to integrate the original project model with all the other discipline-specific models to create a comprehensive, centralized BIM model (if this has not already been done).
  3. Establishment of rules. This is where the clash detection rules are defined based on industry standards, project specifications, and other elements that might potentially affect the results of the clash detection process.
  4. Clash analysis. The bulk of the clash detection process is performed in this step, in the middle of the entire sequence. Specialized software analyzes 3D models to identify potential conflict locations between model elements using a predefined set of rules as the baseline.
  5. Identification of conflicts. Despite its somewhat misleading name, this step revolves around manually checking clash detection reports to look for the conflicting locations that are found. If there are multiple conflicting spots in the model, it would also be wise to prioritize all existing clashes based on their significance and potential impact on the structure.
  6. Resolution of conflicts. The information collected in the previous stage should be enough to start working on resolving the issues. The bulk of this step is collaboration with the project team to figure out which steps can be taken to resolve the clashes that have been found. This can include the modification of components, design adjustment, or better coordination of the specific elements that clash.
  7. Documentation and implementation of clash-resolving solutions. Once the proper clash-resolving methods have been established, they are performed on the existing BIM model. Documenting how each clash is resolved can potentially improve the timeframe for the resolution of similar clashes in the future.

While that is the end of a single clash detection process, some specialists include ongoing, regular repetitions of the clash detection mechanism as another step in this sequence. Clash detection should be performed on a regular basis to ensure the consistency and completeness of the project, but we are not including this step as part of our guide.

General recommendations for clash detection processes

The clash detection process can differ significantly depending on the software that is used to perform it, as well as on plenty of other factors. At the same time, there is still a lot of common ground between most clash detection efforts, and some of these efforts are worth mentioning to ensure that all users perform at their best when it comes to clash detection.

In this case, we are going to explain two different elements of clash detection:

  • Interpretation of clash detection reports.
  • Time frame for clash detection in the context of project realization.

Correct interpretation of clash detection results

The precise structure of a clash detection report varies a lot depending on the software used, but the general structure is similar for most options on the market. The bulk of a clash detection report is the clash list, a list of all the clashes found by the software, and there are plenty of details that might be included here:

  • Severity of clash (typically separated into hard clashes and soft clashes).
  • Location of clash (including elements that are affected or other reference points for easier location in the model).
  • Visualization of clash (3D model views, screenshots, etc.).
  • Groups of elements affected (structural elements, architectural elements, and so on).

We mentioned prioritization above, and this process is necessary when handling significant clash detection reports. It is also useful for smaller reports, greatly enhancing the overall clash handling process. Here are several general recommendations when it comes to prioritizing clash detection results:

  • Prioritize hard clashes over soft clashes.
  • Prioritize clashes that are most likely to cause significant process disruptions (if a clash affects a building’s HVAC, electrical, plumbing, or other similar system).
  • Prioritize clashes that might cause expensive material or equipment replacements if not solved before construction.
  • Prioritize clashes that might significantly disrupt the existing project realization schedule (such as if re-fabrication is necessary, for example).

There are also plenty of general recommendations that are much less specific but can still be helpful in most situations in the context of clash detection processes:

  • Track and document all clashes and the changes made to avoid them.
  • Try to resolve the cause of the clash instead of just addressing the symptoms and leaving it at that.
  • Keep stakeholders in the loop about the clash detection process by organizing meetings, proposing solutions, delegating, and so on.

These recommendations may seem relatively basic, but they are also extremely helpful when it comes to interpreting and resolving the results of clash detection.

Correct time frame for performing clash detection

It should be noted that the best possible time to perform most clash detection processes is during the design or pre-construction phases. The biggest reason for that is the cost and effort required to resolve geometry clashes.

Resolving a clash between different structural elements on-site during the construction phase is much more challenging. Potential solutions for such situations will be far more expensive than any model correction in the design phase since the model is, at that point, the only representation of the project, and it is much easier to modify.

Different types of clash

It would be completely unreasonable to say that all clashes are the same. Different types of clash have drastically different effects on the model and differing potential approaches to resolution. It is useful to differentiate three main types of clash: hard, soft, and workflow clashes.

Hard clash

A hard clash is the most basic example of the three, in which two objects or components occupy the same specific place in the model, such as pipes running through steel beams, plumbing lines occupying the same space as air ducts, and so on.

Soft clash

A soft clash is somewhat different and results from indirect interference rather than a direct clash of two objects. A soft clash occurs when a particular element of a model is not given the necessary geometric or spatial tolerance.

Soft clashes are relatively common with MEP services to allow for easier maintenance at a later time. That being said, soft clashes can also cause various issues regarding both safety and maintenance (such as a plumbing line being too close to a live wire, which is a potential short-circuit hazard).

Workflow clash

Workflow clashes (sometimes called 4D clashes) are quite different and mainly involve schedule conflicts, such as general workflow timeline clashes, material delivery clashes, equipment delivery clashes, and more.

Workflow clashes are mostly scheduling related, and the most significant consequence of such clashes is an eventual decrease in the company’s overall efficiency, since a single schedule clash can cause a process freeze.

Types of clash detection software

Because clash detection is heavily tied with the BIM process, clash detection software often works as BIM software, and vice versa, with BIM software offering MEP clash detection capabilities, as well as other capabilities. With that in mind, two main types of clash detection software can be delineated:

  1. BIM integration tools with clash detection capabilities, which are capable of detecting clashes between different kinds of non-proprietary software. Their limitations are mostly connected with the typical problems of integrating different software applications in one place.
  2. BIM design software. This is proprietary clash detection software that can only detect irregularities within its models (the ones created by the same program). Revit is a popular example of this category. It is a massive platform with various capabilities and offers clash detection for its models.

Potential issues with outdated software

Regularly updating clash detection software and CAD/BIM software is a common recommendation in the industry. The inability to follow this recommendation leads to a lot of different issues, including outdated data sets, frequent inconsistencies between different models, and even data silos.

Outdated clash detection software will not be at its most effective when locating and reporting on various clashes and other issues. On the other hand, outdated CAD/BIM software will not be able to provide detailed information for the clash detection process to find all of the clashes and other issues. Both of these issues lead to even more problems down the line, such as lower project realization effectiveness, greater risk during on-site construction, limited project collaboration, frequent issues with coordination, and many others.

Methodology for choosing the best clash detection and BIM design software

The market for clash detection software is vast and varied, so it is quite hard to list all of the options. However, we have made a list of 9 of the best-known participants in the market, which is provided below. At the same time, it would only be logical to provide the methodology used to choose these specific solutions.

The categories used in this article are:

  • Customer ratings
  • Key features and advantages and disadvantages
  • Pricing
  • Personal opinion of the author

Customer ratings

Construction software is a highly competitive field, with hundreds of solutions competing for the attention of the average client. This is true of most types of construction software, and clash detection software can also be difficult to find because of the many different options on the market.

Review aggregation websites can be extremely helpful in this situation. Resources such as Capterra, TrustRadius, and G2 each have hundreds of thousands of documented reviews on their respective websites. Each review is meticulously screened and checked to ensure its authenticity, and multiple mechanisms are in place to prevent software owners from tampering with public review scores in any way.

These public reviews can also be used to learn about the particular advantages and disadvantages of software that may not be particularly obvious at first. We will transition to the next segment, key features and benefits/shortcomings, using these public reviews.

Key features and advantages and disadvantages

Providing a comprehensive list of the advantages and disadvantages of each solution without having prolonged experience with it can be a rather significant challenge. The same logic applies to presenting the specific set of features that all solutions in this category should have – it is very difficult simply because every solution differs from the others in terms of its use cases, target audience, and more.

As such, the aforementioned review aggregation websites are used to find information about the product, its advantages, and its potential pitfalls. Unfortunately, this list does not even present the advantages and shortcomings of some of the solutions because there are simply not enough public reviews of them to gather information from. In these cases, the official resources are used to create a list of the key benefits the software offers its users.

Pricing

Price is a very important factor for any potential customer. It is possible for a customer to find a particular software application that perfectly meets their needs but whose pricing situation does not allow them to complete the purchase simply because of budget constraints and other factors.

Our list offers plenty of different options in the clash detection software market. Some can be used as comprehensive BIM solutions with dozens of features, while others provide only a very narrow set of capabilities. To make the choice more manageable for the reader, we have tried our hardest to include as much pricing information as possible about every solution, if such information could be found using the official resources.

Personal opinion of the author

This category is likely the most subjective of them all. It exists to include either a brief overview of the solution, the author’s personal take on the specific software, or even unusual information that has not been presented before. As the category suggests, the main goal of this part is to provide a more subjective opinion about the software.

Conclusion

BIM clash detection is a feature that greatly improves modern construction project processes, especially when it comes to collaboration between different stakeholders. Clash detection is a much needed breath of fresh air for an industry that already has a lot on its plate in general.

The industry can also take advantage of numerous technological advancements in the near future (artificial intelligence, machine learning, etc.). This should make clash detection in general much more accurate while also opening up the possibility for more common virtual reality/augmented reality integration, autonomous clash resolution, AI-powered clash detection, and so on.

Of course, these advancements will be counterbalanced by the rise of modular construction and the requirement for real-time collaboration within BIM environments, but there are still many different future changes and improvements to be excited about in the clash detection industry.

Frequently Asked Questions

How difficult is it to integrate clash detection software into a construction company’s workflow?

There is no simple answer to this question, since the difficulty of integrating a clash detection solution depends on multiple factors:

  • The complexity of the clash detection software itself, especially if the solution offers other capabilities besides clash detection. It is relatively common for more complex and feature-rich solutions to be somewhat more difficult to implement.
  • The size of the company that needs to implement a clash detection solution. Smaller companies are usually much more flexible and do not have as many issues with modifying workflows to adjust to changes in their processes.
  • The software that the company already uses is also a massive factor, since businesses that already have some form of BIM implementation in place should not be affected too much by the implementation of clash detection software when compared with implementing such a solution from scratch.

This is just a portion of the potential factors that might affect the overall difficulty of implementing a clash detection solution, one way or another.

How useful is clash detection outside of the design phase?

The most obvious advantages of the clash detection process are at their most useful in the design phase. Technically speaking, the clash detection process can be used during the construction phase, as well, to make sure that prefabricated parts that have not yet been installed on-site were made in accordance with all of the necessary parameters.

Other than that, clash detection is not exactly applicable during the planning phase, because it needs a complete BIM model to work in the first place. Alternatively, clash detection is also not particularly useful during the post-construction phase, because it does not interact with structures that are already built.

In all fairness, the correct realization of the clash detection process benefits all project phases after it, but this is the extent of clash detection’s influence.

What are some of the most common pieces of advice and best practices for clash detection?

Many of these recommendations may seem somewhat generic, but their usefulness is not to be underestimated:

  • Keep stakeholders informed about the process of clash detection and clash resolution.
  • Perform the first clash detection cycle as soon as the BIM model is ready so that you have a bigger head start on solving all of the potential issues.
  • Record and document all of the results of clash detection, including the changes that were made to resolve them.
  • Try to analyze past clashes to see if there is some sort of pattern to be found, making it possible to deal with the root of some clashes instead of fixing the clashes themselves over and over again.
  • Use clear guidelines for clash detection, it is important to find a middle ground between noticing every minor overlap and missing important large clashes.
  • Clash detection software with competent integration capabilities is preferable for all users, as it greatly simplifies the process of clash detection and the extraction of the results.
