3D Laser Scanning and CAD Reconstruction of a Sawmill \u2013 Digital Basis for a Retrofit Project<\/strong><\/h2>\n

Initial Situation<\/strong><\/h2>\n

For the planning of a comprehensive retrofit project in an existing sawmill operation, a reliable digital as-built basis was required.
The existing building structures had evolved over time and were not available in up-to-date technical documentation.<\/p>\n

For planned modifications, extensions, and the integration of new plant equipment, precise geometric data was essential\u2014particularly for load-bearing structures, roof geometries, traffic areas, and machine environments.<\/p>\n

Conventional survey methods are of limited use in such facilities: complex geometries, restricted access areas, and large spatial dimensions make manual measurement time-consuming and error-prone.
For this reason, a complete 3D laser scan<\/strong> of the facility was commissioned, including the digital reconstruction of all relevant building elements<\/strong>.<\/p>\n

Scope of Services<\/strong><\/h2>\n

The project consisted of several coordinated work phases:<\/p>\n

On-Site Laser Scanning<\/strong><\/h4>\n

The on-site scanning was completed within two days. The following areas were captured:<\/p>\n

    \n
  • Building envelope<\/li>\n
  • Roof structures<\/li>\n
  • Production halls<\/li>\n
  • Traffic and storage areas<\/li>\n
  • Structurally or functionally relevant interior zones<\/li>\n<\/ul>\n

    The scan data was provided as a point cloud in E57 format<\/strong>, supplemented by a viewer for direct visual inspection.<\/p>\n

    Data Processing and Cleaning<\/strong><\/h2>\n

    The point cloud was cleaned, filtered, and segmented to prepare it for further processing and accurate modeling.<\/p>\n

    CAD Reconstruction in HiCAD \/ HELiOS<\/strong><\/h2>\n

    Based strictly on the scan data, the following elements were reconstructed:<\/p>\n

      \n
    • Main building geometry<\/li>\n
    • Roof landscapes<\/li>\n
    • Concrete and foundation areas<\/li>\n
    • Relevant geometries in proximity to machinery<\/li>\n
    • Section planes, reference levels, and planning axes<\/li>\n<\/ul>\n

      The modeling process was carried out with iterative coordination with the client\u2019s project team.<\/p>\n

      Data Exchange and Project Integration<\/strong><\/h2>\n

      Collaboration was handled via a shared cloud workspace. The delivered data included:<\/p>\n

        \n
      • STEP files<\/li>\n
      • PDF views<\/li>\n
      • Updated CAD models reflecting design changes<\/li>\n
      • Supplementary screenshots and technical evaluations<\/li>\n<\/ul>\n

        Feedback cycles were managed through written markups, phone calls, and online meetings, allowing changes to be implemented efficiently.<\/p>\n

        Final Deliverables<\/strong><\/h2>\n

        The final project output included:<\/p>\n

          \n
        • A fully usable STEP model (~182 MB)<\/strong><\/li>\n
        • Complete point cloud datasets<\/li>\n
        • Viewer files<\/li>\n
        • Structured project documentation<\/li>\n<\/ul>\n

          These datasets now form the basis for retrofit planning, interface construction, and subsequent plant integration.<\/p>\n

          Project Challenges<\/strong><\/h2>\n
            \n
          • Large and complex building structures<\/li>\n
          • Varying ceiling and roof heights<\/li>\n
          • Highly confined and difficult-to-access areas<\/li>\n
          • Lack of existing as-built documentation<\/li>\n
          • Requirement for millimeter-accurate data for steel construction and plant engineering<\/li>\n<\/ul>\n

            The use of 3D laser scanning enabled full digital capture of the facility without significant disruption to ongoing operations.<\/p>\n

            Client Benefits<\/strong><\/h2>\n
              \n
            • Precise geometric data as a reliable planning foundation<\/li>\n
            • Significant time savings compared to manual surveying<\/li>\n
            • Reduced risk through planning based on verified as-built data<\/li>\n
            • Direct usability in CAD, 3D engineering, and BIM workflows<\/li>\n
            • Complete digital documentation for future projects<\/li>\n<\/ul>\n

              Conclusion<\/strong><\/h2>\n

              By combining modern 3D laser scanning, professional data processing, and precise CAD reconstruction, a robust digital foundation was created for a large-scale retrofit project in a sawmill environment.<\/p>\n

              The delivered data ensures planning reliability, simplifies coordination between subsequent trades, and accelerates all further engineering steps.<\/p>\n

              The sawmill is not merely documented\u2014it is prepared for the future.<\/p>","protected":false},"excerpt":{"rendered":"
