One of the biggest challenges in an existing building renovation is accurate documentation of the building MEP systems. 3D scanning can be a vital part of this process.
If you even have blueprints, it’s likely that you’ll find that the existing systems were not built as originally designed. And it’s not easy getting accurate measurements in crawl spaces or above ceiling tiles.
PrecisionPoint helps MEP engineers overcome these challenges with our Scan-to-BIM Services. One advantage of 3D laser scanners is that they can fit into small spaces where people can’t go. 3D laser scanning quickly and accurately captures infrastructure located in hard to reach plenum spaces, including visible structural, MEP, and HVAC system elements. Today’s advanced point cloud post processing software then allows PPI to “connect the dots” between what the scanner could see and what was hidden to create a complete and accurate engineering MEP as-built point cloud model. In comparatively more open spaces like mechanical rooms, 3D laser scanning is similarly the fastest, most precise method of collecting as-built pipe and equipment information as point clouds that are accurate within 2mm to 5mm.
PrecisionPoint then uses automated feature extraction software tools to 3D model elements like pipes and ducts and convert them to BIM object families. When converted to a BIM, the point cloud model allows engineers to quickly access and analyze as-built conditions prior to commencing the design process. If a retrofit has already been designed, PrecisionPoint can use the new as-built BIM to conduct 3D clash analyses so problems can be resolved before construction begins, saving both time and money.
