Software catches 3 million project clashes in 45 minutes
How long does it take to detect three million clashes on a large project? Just 45 minutes, according to Revizto in a presentation during the Digital Construction Summit.
Lewis Guy, VDC implementation manager at Revizto, demonstrated the newly launched Revizto+ platform with automated clash detection during the Summit session, Enhancing communication and collaboration with technology, sponsored by Revizto.
Guy said: “Generating the clash results is really quick. We’ve had Revizto+ on one of our biggest projects in the UK where we ran the search as everything against everything just as a test and we generated three million results in 45 minutes – it’s quick and can handle massive datasets.”
Revizto director Rhys Lewis revealed: “Clash automation is something we’ve been working on in the background for the last two years. Our development has listened to our clients’ feedback and what they’re asking for.”
Guy added: “We’re solving a problem the way BIM coordinators and managers want it to be solved. Revizto+ clash detection is built entirely around ‘search sets’, whether for models or specific data within the models (all the ducts or all the pipes for example). As Revizto is a collaborative platform, more than one person can run clash detections and review the results at the same time.”
The platform can search for five different clashes: hard, clearance, clearance with independent horizontal and vertical offsets, tolerance and tolerance with independent horizontal and vertical offsets. Detection searches can be grouped for further refining, and search results can be filtered.
Guy said: “What we’ve done with Revizto is make it the tool that can bring in all the files from all different locations, run the clash detection, you can share that information and then we have the ‘switch-back’ functionality that allows you to get in to your original models and fix the problems. It’s a connected process in one tool, not multiple tools. The clashes can be resolved a lot quicker because it’s easier for everyone to understand what’s going on.”
Kier is a recent convert to Revizto and is using the platform on the £64.3m Fitzalan High Council for Cardiff City Council. The school for 1,500 pupils includes 100 classrooms plus sports pitches and a swimming pool, and is scheduled for completion in 22/23 academic year.
Russell Baker, senior BIM manager at Kier Construction Western & Wales, said: “All the of the supply chain have embraced the implementation of Revizto.
“Our design coordination review started with clash detection. This was carried out in Navisworks, with the clashes then exported into Revizto. However, this process will probably change with Revizto+.”
Jonathan Walters, senior BIM coordinator at Kier Construction Western & Wales, added: “[Here’s] one of the benefits of Revizto’s plugins [from Archicad to Vectorworks, via Navisworks and Revit]: our steel manufacturer is using Tekla, and traditionally he’d send out his model via an IFC file to the architect; but the architect couldn’t pinpoint that IFC on to the correct location because they used different shared coordination systems; when we brought our Tekla model into Revizto, it overlaid in the correct location, so the architect is now reviewing the subcontractor’s models and drawings in Revizto instead of bringing in to his own Revit file.”
The Summit was run as a virtual even with nearly 1,000 industry professionals registering for the three webinars over two days. Partners for the event were the Chartered Institute of Building, Revizto and Trimble Viewpoint, Construction Manager and BIMplus.
