Precision Laser Scanning Services for Accurate Reality Capture

At PLC, we deliver cutting-edge 3D laser scanning solutions that set a new standard for precision and efficiency in capturing existing conditions. Utilizing the advanced Leica RTC360 3D Laser Scanner, we achieve survey-grade accuracy to document architectural, structural, and MEP layouts with exceptional clarity. This state-of-the-art technology enables rapid, high-resolution reality capture, empowering your team to make informed decisions with confidence. Whether you’re planning renovations, retrofits, or new construction, our scanning services ensure you start with a reliable digital foundation.

What sets PLC apart is our expert Mapping & Modeling team, who transform raw scan data into actionable deliverables—including custom CAD drawings, intelligent 3D models, and immersive virtual tours. These outputs are ideal for design validation, prefabrication, and facility upgrades. We further enhance your data with information tags that highlight key opportunities and improve situational awareness across your team.

With PLC, you don’t just scan a site—you unlock its full potential! 

The Leica RTC360 is a high-end 3D laser scanner from Leica Geosystems (part of Hexagon). It’s widely recognized in the industry for:
  • Extremely fast scanning: Up to 2 million points per second.
  • Full 360° × 300° coverage with integrated HDR imaging for colored point clouds.
  • Automated pre-registration in the field (via Cyclone FIELD 360 app/software).
  • High portability, quick setup (full scans including HDR imagery in under 2 minutes in many cases).
  • Applications in construction, architecture, BIM (Building Information Modeling), as-builts, and more.
