How do you use BIM to support clash detection and resolution in complex projects?

BIM plays a pivotal role in clash detection and resolution by consolidating multidisciplinary models. Utilizing clash detection tools (like navisworks, solabri, revizto) within BIM platforms allows for the identification of potential conflicts among different building components. Through 3D visualizations and clash reports, discrepancies are pinpointed early in the design phase. Collaborative efforts are then facilitated for efficient resolution, minimizing rework and optimizing coordination among various project stakeholders. This streamlined clash detection process within BIM enhances project efficiency and helps ensure a smoother construction workflow.

Before BIM, finding design problems was like walking in the dark. With BIM, it's like turning on the light. We can easily spot where things might go wrong, like seeing a step before you trip over it.

BIM is crucial for clash detection and resolution in complex projects. By creating a detailed 3D model and integrating various disciplines, BIM software identifies clashes between structural, architectural, and MEP elements. Resolving these clashes early saves time, reduces rework, and ensures project quality, ultimately leading to cost savings and smoother construction processes...

in some project, clash detection and resolution is used as after submission as part of handing over and not related to on going process as part of quality of the work delivered. on the other hand, in well managed projects with processes. the clash detection is used on weekly/monthly bases between all disciplines/partners to prevent clashes as a part of spatial coordination that reflect at the end as the quality of management and the project delivery.

Using BIM for this is like giving someone superpowers to see through walls. We can spot and fix problems in our plans before they become real headaches on the construction site.

Autodesk produced various products. AutoCAD is the final destination for providing drawings. Dynamic block has eliminated weak points of repetitive issues with changing the dimension in AutoCAD; in other words, AutoCAD can be parametric, such as Revit's family. Therefore, the advantages of BIM are as follows. 1-all engineers can work together and transmit all information without wasting time. All changes can be observed, and all engineers can easily track the updated issues, therefore increasing the contribution 2- the creation of a great database that is 3D visual 3-all engineers can integrate analysis, design, and final drawings, and it is easy to exsert even tiny changes in outputs. 4-the construction management is more efficient

It's like having a 3D puzzle where you can fit all the different pieces from various disciplines together seamlessly. Automated checks quickly highlight any mismatches. Then, using tools like color coding and markups, we can easily spot, communicate, and resolve these issues. It's not just about detecting problems, but also about solving them efficiently and visually.

using BIM in Clash detection it gives the power of control and time traveling as you have the technology in software, the 3D presentation with high LOD, and all information may be required in determine the way of solving clashes before going deep in design or construction.

**Using BIM for Clash Detection and Resolution** **1. What is BIM Clash Detection?** - **Definition**: BIM clash detection identifies and addresses conflicts among different construction models in a virtual environment. - **Types of Clashes**: - **Hard Clash**: Physical overlaps between elements (e.g., a pipe running through a wall). - **Soft Clash**: Spatial conflicts where elements are too close, violating clearance requirements. - **Workflow Clash**: Scheduling conflicts where different trades need to work in the same space at the same time. **2. Benefits of BIM Clash Detection** - **Early Identification**: Detects issues in the design phase, preventing costly on-site changes.

Using BIM for clash detection is like having a high-tech detective on the team. It pinpoints where problems might pop up in a build, allowing us to fix issues before they turn into costly, time-consuming headaches on site. This foresight not only saves money but also ensures a smoother, more efficient construction process.

In the past, significant time was spent navigating coordination challenges in plan, relying on imagination to resolve clashes. However, the adoption of BIM clash detection has revolutionized this process, ensuring the accuracy and coordination of designs to a considerable extent. This technology not only expedites coordination efforts but also prevents on-site miscoordination during construction, leading to substantial time savings.

BIM has revolutionized the AEC industry industry by offering a collaborative and comprehensive approach to project development. One of the key advantages of BIM is its ability to streamline clash detection and resolution processes, significantly improving efficiency and reducing the likelihood of errors during construction. Below are some advantages of using BIM for clash detection and resolution: 1. Early Identification of Conflicts 2. Multidisciplinary Coordination 3. Automated Clash Detection 4. Detailed Clash Reports 5. Real-time Collaboration 6. Enhanced Communication 7. Reduction in Rework Costs 8. Improved Construction Sequencing 9. Data-driven Decision-making

Coordination and Collaboration is the key element of BIM. It saves time as well as cost on construction site while keeping design perspective of system. Hence, resulting in overall productivity, reducing rework at construction site. Improving quality of work and reducing burden of manual updations. Giving more adaptable model to rely on while fabricating it. One should be aware of different trades as well as effects caused by their model change during the process.

Tackling BIM for clash detection can be challenging. Imagine trying to focus on each note in a symphony orchestra — the amount of information can be overwhelming. It's not just about seeing the problems; it’s about setting clear rules for checks and streamlining the workflow. This requires a careful balance of technology know-how and practical wisdom to filter the noise and focus on what truly matters for a successful project outcome.

For me, one of the biggest complications I have encountered in my years as a BIM Manager when it comes to clash detection has been the usual disconnect between the design software and the coordination software itself. In this way, the federated model is not connected with the actual design, and every time an interference is detected, it is necessary to go back to the design tool and load the corrected model back into the federated model. This workflow makes version control difficult, and adds extra processes that ultimately slow down the entire design and coordination process. However, we are increasingly finding cloud-based solutions that connect both modeling and coordination tools, reducing the possibility of making mistakes.

One of the main challenges that you have to adress before making clash detection is to figure out what is your expected output from the clash. Because this will decide the types of tests (Hard, Clearance , Duplication) , the category that you will check, the tolerance that will be used, the format of the exported reports. Additionally, the criteria for the clash reports will vary depending on the stage you are doing the clash check for schematic, DD, or construction.

One of the problems that comes up time and time again is how the process is presented. Using Navisworks to run clash detection is fine, but a clash tolerance needs to be added and tests refined. Saying that the "X" model has 1000 clashes with the "Y" model is not helpful to anyone. Assigning clashes to the relevant personnel for resolution speeds up these traditionally long workshops. In addition, someone (defined in BEP) needs to go through the tests and do a sanity check, as not every clash is black and white. For instance, a grille clashing with a ceiling is an accepted clash. Pipes of a certain size that rise between floors and clash with slabs could be considered acceptable, as there may be an agreement to core these on site.

in my experience the most challenges are coming from people in the coordination process as follow. -not understanding how much information or details they should provide -deploying action to the team when who is taking decision not communicating with the team -when they not understanding how fast they should take action when updating -how is the clash detection and coordination depends on the quality of BIM Models delivered

To really get the most out of BIM, you need to be a bit of a wizard. Tools like Navisworks and Solibri...etc are our magic wands, but it's up to us to use them right. It's about mixing smart tech with smart thinking.

When it comes to BIM clash coordination, software is proving instrumental: Software for BIM Clash Coordination: 1.Navisworks Manage: Facilitates model aggregation from various disciplines, offering clash detection and management features. 2.Solibri Model Checker: Provides automated clash detection, code compliance checks, and issue resolution in BIM models. 3.Revizto: Enables real-time issue tracking and resolution in 3D models, supporting effective coordination among project stakeholders. 4.BIM Track: Facilitates model coordination and issue tracking in a collaborative environment, enhancing clash resolution efficiency. 5.CUBE: Another valuable software utilized in BIM clash coordination

to overcome the challenges of people in clash detection and using BIM. it comes on several steps step of management and contract in the BEP which describe the frequency, importance, and involved people with responsibilities Team, when selecting the responsible and provide a deploying plans internally and provide training plan focused on the coordination process requirements and managing how the process will be took in place. software, it comes when selecting the most suitable software that match all used software with all partners and following up on how it will be used in clash detection and resolution

Always prepare a clash matrix that covers all your needs\requirements from running the clash detection. Test this matrix before run it. It is always betters to use search sets not selection sets. Make your sets based on element category & file type to be able to use it for any other projects.

Overcoming the challenges of using BIM for clash detection and resolution requires proactive measures. From my perspective, comprehensive training and education programs help professionals adapt to new software and workflows. Standardizing file formats and improving interoperability between BIM tools address compatibility issues. Effective communication and collaboration platforms facilitate stakeholder engagement. Establishing clear protocols for data integration and model management ensures accuracy and consistency. Embracing a culture of continuous improvement and addressing resistance to change through incentives and support further enhance the successful implementation of BIM clash detection and resolution.

Para mí el objetivo es no tener que utilizar software de clash detection. Los errores y problemas deben solucionarse en la fase de coordinación, un buen coordinador guiará a todas las disciplinas y definirá estrategias para que los choques no existan en un principio. Se podrá utilizar el software de detección de choques para comprobar pero la mejor práctica es la prevención y la planificación

Thinking back to the old days of 2D plans, spotting clashes was super tough, especially in big, complicated projects. It took forever and mistakes were easy to miss. Now, with BIM, it's like having a magic tool that makes everything easier. But remember, even with this magic, it's important to double-check things yourself from time to time.

In complex projects, BIM facilitates clash detection and resolution by generating a digital model that integrates diverse elements. This allows for the real-time identification of conflicts during both the design and construction phases. Stakeholders can leverage this visual representation to promptly address clashes, ensuring efficient resolution and minimizing potential project delays or complications.

in the market we still have some who is using 2D in coordination and when asking and provide the consultation. we found that it not related to the software or BIM as technology but it related to the use of BIM and quality that is provided in models as who implemented as BIM it just represents the 3D of the object without any consideration to information, details, workflow, processes, quality, or way of work so it can't be used in clash detection and resolution.

I think VR and AR are important and cause easy understanding for everyone. This industry extends to other subjects such as noise and vibration, rehabilitation, and health monitoring. I hope the BIM will be universal for all issues and all people know this final step is based on the first step( clash detection)
