3D Laser Scanning & As-Built Plans
Reality capture with millimeter LiDAR scanning and CAD/BIM model extraction
High-precision reality capture of existing Montreal buildings using 3D laser LiDAR scanning. Converting registered point clouds into pristine 2D CAD drawings or intelligent 3D Autodesk Revit as-built models.

Ground Truth for Complex Existing Buildings
Montreal heritage homes, century-old triplexes, and industrial conversions frequently deviate from straight lines. 3D reality capture removes guesswork before construction starts.
What you receive upon project completion
