While scanning technology is nothing new, improvements in its ease of use are expanding its applications. Using a Leica BLK360 scanner, two designers without prior survey or scanning experience captured a large portion of a wastewater treatment plant’s tunnels and connected facilities in four days, in preparation for a design project. New piping is to be installed in these existing facilities, which are already crowded with piping and equipment—a common scenario in similar long-established facilities. A rough routing drafted in Revit software was added to Navisworks software, along with the point-cloud files, enabling direct interference checks between the two without converting the point cloud to a model. Attendees will discover the detailed workflow they should apply to use this technology, and learn how it was used on this project in Ohio.
