Comprehending BIM Clash Detection & Making It Efficient

In the realm of Building Information Modeling, BIM clash detection facilitates in identifying clashes during the design and preconstruction stage. The action fits in a constructability analysis to find issues that are left unchecked and can lead to difficulties, cost overrun, and productivity loss in the actual stage of construction. Architects, Engineers, and Construction professionals can access clash detection in various software applications, like NavisWorks, Tekla BIM sight, Solibri Model Checker, ArchiCAD, Revit, and many more.

What Constitutes to be a BIM Clash Test?

A test constitutes to be a predefined set of components that need to be checked for collisions. Usually, there are two sorts of validations – interconnecting as well as clearance check, seldom called “soft check”. An interconnecting clash constitutes to be a collision of the geometries of two substances. Usually, a clearance check stands for a collision amongst a predefined buffer around the geometry of two objects. The buffer gets established in some clash detection software application or modeled in the BIM object for mechanical equipment maintenance. This is also operated for the clearance of door access, stair run, precast concrete panel installation, steel truss deflection, and much other stuff.

The ideal way is to plan a clash test and create what is usually called the “clash matrix” for delineating blends of disciplines and precedence grounded on construction schedule and deliverable. The chronology of the BIM clash test is significant to reduce repetitions between model updates.

What is BIM Clash Rule Formula?

A clash rule formula is used to choose particular objects necessary to be incorporated in a clash test. It is vital to check the uniformity of the model tree in case the clash regulation is to select an object. A competent way to create the naming convention of an object and parameters is using the Industry Foundation Classes (IFC) for model sharing. Further, a clash rule encompasses Boolean expressions like and/or, or specific exclusion standards.

What is BIM Clash Report Document?

A BIM clash report happens to be a document shared with AEC project stakeholders on a specified project through PDF, HTML, XML, or additional formats. The document constitutes to be a “conventional” method of allocating issues established within the clash detection software application and demands some additional time for setting up, tracking, and solving problems over time.

How to Assign the Issues Competently through BIM?

A ‘traditional’ report is not an effective method of data transfer to the users in the modeling software where the concerns need to be resolved. However, BIM Collaboration Format constitutes to be an open format that helps to save the time of a user in finding the place of clashes or the pre-requisite time essential to obtain an apt view while moving from one software platform to the other. BIM Collaboration Format happens to be the key for optimizing the clash detection process and must be used by the BIM Modelers or the BIM Engineers undertaking clash detection. Further, platforms are focusing on conflict tracking like BIM Track to facilitate issue transfer through various phases.

The Way to Fix a BIM Clash

A technique of reducing common place BIM modeling tasks results in detecting loads of clashes for script-based modeling automation resolutions like Dynamo. To take an instance, if you have an HVAC system through a fire-rated panel and want to add a special accessory at this place, you can use Dynamo for placing the accessories automatically at the locations and create an opening in the wall mechanically in Revit.

Another growing trend is using clash-free auto-routing with a computational design like GenMEP. The essential facet of GenMEP is the ability to use algorithms for routing MEP systems without clashes mechanically during the design development stage.

The crux of the Matter – Improved Clash Coordination will lead to Better Buildings

Clash detection existed for a long time but what makes it valuable is the BIM dimension that you define around it. Using out-of-the-box software applications is not an ideal solution for the timely resolution of an issue without substantial effort. Find out the common issues encountered on-site, set clash tests consequently, and then check BIM models for specific cases. Detect your clash at the right moment and as per your construction schedule before the onset of the construction workflow through 3D BIM Modeling. Improved clash coordination through BIM will lead to better coordination and better building.

Top 6 Benefits of Building Information Modeling in Construction

Building Information Modeling in Construction has been a hot and happening topic in the AEC sector for quite some time. Still, there is a lot of misconception about BIM in the construction sector about how it facilitates the contractors. A common delusion about BIM is that it is just a technology, or it refers to 3D design. BIM involves a practice for creating & managing project information, resulting in a Building Information Model, containing digital accounts of each aspect of the physical project.

Whereas BIM is typically related to design and preconstruction, it aids every phase of the construction project life-cycle, even after the construction is over. BIM facilitates construction projects to be created virtually before they are built physically, eradicating a lot of the inadequacies and difficulties that ascend during the building development.

Here are the top 6 benefits of BIM in construction:

  1. Improved Collaboration & Communication

Digital Building Information Models facilitate sharing, joining forces, and versioning that is not possible through paper drawing sets. Through cloud-based tools like Autodesk’s BIM 360, BIM collaboration seamlessly occurs across all disciplines in the project. The BIM 360 ecosystem permits project teams to share 3D models and manage the planning, ensuring that all design stakeholders have an improved understanding of the project. Cloud access also enables AEC project team members to bring the workplace to the construction field. Through applications such as BIM 360, project teams are assessing drawings and models onsite on their mobile devices, ensuring access to updated project information at any point of time.

  • Model-Based Cost Estimation with 5D BIM

Several AEC companies understand that including estimators earlier in the construction planning stage allows effective construction cost estimation that ultimately paves the way to the development of model-based cost estimating called 5D BIM. Implementing BIM tools like Revit and BIM 360 Docs mechanize the laborious work of quantifying & applying costs, enabling estimators to emphasize advanced value factors, like detecting risks.

  • Project Visualization with 3D BIM& 4D Simulation

Implementing BIM, construction professionals can plan and visualize the entire project at the pre-construction stage. 4D Construction simulation and 3D BIM visualization facilitate clients to experience what space will look like providing the capability to make modifications before the beginning of the construction process. Having a detailed overview of the initial stage of the project reduces costly and laborious changes in the future.

  • Improved Coordination & BIM Clash Detection

Building Information Modeling lets you enhance coordination among subcontractors and other project stakeholders detecting clashes related to MEP (Mechanical, Electrical& Plumbing) services, internal clashes, and external conflicts before the commencement of the construction work. An electrical conduit may clash with a steel beam. A doorway may not have adequate clearance. Using software applications like Autodesk BIM 360 Glue helps you get automated clash detection.By evading clashes, rework gets reduced. Building Information Modeling provides you the prospect to plan it accurately before building onsite and thus you can get rid of last-minute alterations and unexpected concerns by allowing easy review and comments across the multiple services.

  • Reduced Project Cost &Risk Alleviation

According to the McKinsey study, it is found that 75% of companies implementing BIM reported positive returns on their investments. BIM can save your cost in numerous ways if you know how to take advantage of this technique. Faster collaboration with contractors results in the reduction of tender risk payments and lower insurance costs and fewer variations. Getting a better project overview before the starting of the construction process enables enhanced prefabrication and waste reduction on unused resources. Prefabricated components can be certainly bolted in place instead of getting created on-site.Labor costs on documentation and miscommunications are also reduced. So companies are fast adopting BIM for reducing costs and mitigating risk.

  • Enhanced Construction Scheduling with 4D BIM

BIM also helps to save money by decreasing the time of project lifecycles and removing the setbacks of construction schedule setbacks. Building Information Modeling allows design and construction documentation to be created at the same time, adapting to the new information like site conditions.Thus construction schedules get planned and communicated accurately, enhancing coordinationon-time or promptly.
