3D Laser Scanning
HDT is a leader and innovator in 3D laser scanning. Our expertise in laser scanning has brought us all over the world to work with clients across various industries. With hundreds of millions of square feet of digitized facilities worldwide speaks to the reliability of our deliverable. Our AIA award-winning methodologies integrate multi-mode scan data into a single point cloud to create as-built conditions, virtual job sites, and more. PMC’s team of engineers and scanning technicians works with our clients to create custom deliverables that aid in the design, planning, and execution phases of any construction project. Traditional methods of field verifying existing buildings have the potential to introduce inaccuracies and are incredibly inefficient. Not only does 3D laser scanning quickly capture accurate as-built data, but the point cloud data is also natively capable for direct import into BIM software, such as Revit or Navisworks. Laser scanning is a fast, accurate, and non-intrusive way to collect as-built construction data, and eliminates the need to return to the site for additional measurements.3D laser scanning is proving critical to the success of technically challenging building projects and projects with condensed schedules. By beginning a project with as–builts created by our CAD technicians, project teams can take full advantage of the point cloud’s accuracy captured by the 3D laser scanner. Common use cases are comparing new construction to the as-built model or drawings for quality assurance. General contractors benefit from having an accurate starting point on projects. Better information from scanning and as-built modeling upfront reduce risk by creating strong documentation of existing conditions. Later, the scan and as-built documentation can be used in digital coordination and collaboration, ultimately exposing design discrepancies and clashes before they manifest into change orders during construction. In “Cost Management in Construction Projects: Rework and Its Effects,” a study published in the Mediterranean Journal of Social Sciences, it was found that around 30% of the work performed by construction companies is actually rework. With laser scanning, as part of a larger VDC strategy, contractors’ cost savings can be enormous. A study published in Automation in Construction showed optimized efficiency of the renovation process by 15%; eliminated design changes by 30%; and reduced rework by 25%.No matter how you look at it, a solid VDC strategy starting with accurate as-builts can save thousands on any renovation or new construction project.
