Clash Detection in BIM – A Savior!

A clash on site could cost one immensely. The wastage of materials, the cost of the new material, the labor cost on-site and in the office resolving the issue, the machinery cost; the list could keep going. Furthermore, the delay that would be caused by the schedule and any penalties and legal costs could be added trouble. From $1000 to $10,000, based on the trades involved and when it is detected, the cost of clash could be taxing! Identifying a clash in a virtual building environment will cost way lesser than that to face it on-site.

One of the key reasons why 3D coordination has become so popular is its capacity to envisage glitches in the 3rd-dimension. Clash detection is the plain sailing of BIM! Investing in products like Revit, and Navisworks can largely diminish the chance of the need to mend a problem on-site; or reverting to the drawing board and ceasing works while the error is worked out. Even if we detect say 30 clashes prior to reaching the site, the amount invested in the software and hardware, and training is easily worthwhile. In the case of more complex projects, the number of clashes could be easily in the thousands.

With Navisworks, a central VDC or BIM coordinator integrates the models (ArchitecturalStructuralMEP) and analyses and communicates with members of the various team disciplines to resolve any clashes identified. The latest technology for clash detection is the BIM 360 Glue. With BIM 360 Glue, one can work amidst various domains in a more real-time environment. The various teams can upload their models anytime and collaborate with other disciplines, thereby reducing review cycles and generating better models and drawings.

The benefits of Clash Detection in BIM are momentous. The remarkable reduction in RFI’s, proactive resolution of problems within hours and not weeks and months, the review meetings dealing only with rigid issues that concern and not the petty issues easily resolved in minutes, and of course saving in cost are the many benefits of clash detection in BIM. We have more and more architects, engineers, and contractors realizing the power of the models. They are reaping as many benefits as possible from a single model and working with their extended teams to achieve what they want.
