Between 2020 and 2021, Fenstermaker completed a major laser scanning project that consisted of approximately 5,200 laser scans, with half collected from a man-lift. The purpose of this scanning effort was to capture sufficient data to create piping and instrumentation diagrams (P&IDs), isometric drawings, and a digital twin model for a unit that had no as-built records. This project required robust data from all vantage points to ensure that engineers could develop accurate drawings and records as well as experience benefit from the digital twin model. In addition to the laser scanning effort, Fenstermaker also integrated LiDAR technology into the workflow to create a seamless data set from all angles of the facility.

The field effort consisted of a total of four field crews mobilized for a period of two months. To accomplish this tall order, Fenstermaker’s personnel executed the work with the latest survey equipment:

• Pair of Leica RTC 360 laser scanners
• MS50 and MS60 total-station
• DJI Matrice UAV fitted with a Snoopy MiniVux 2 LiDAR unit

Data formats included the following:

• Registered E57’s
• Aveva LFM
• AutoDesk Recap
• LAS files
• Google Earth tiles
• Digital orthomosaic
• Civil survey topographic deliverables
