Laser scanning captures three-dimensional measurements of physical objects and spaces using laser technology, creating detailed digital models for design, fabrication verification, as-built documentation, and reverse engineering. This technology improves accuracy and reduces measurement time compared to traditional methods.

Scanning applications in fabrication include as-built documentation of existing facilities for brownfield projects, dimensional verification of fabricated equipment before shipment, reverse engineering existing equipment for replacement part fabrication, and quality control inspections comparing fabricated items to design models.

Laser scanners emit laser pulses and measure reflection time to determine distances, building point clouds containing millions of measurements. Processing software converts point clouds into usable formats—3D CAD models, dimensional reports, or comparison analyses showing deviations from design intent.

Benefits include comprehensive measurement capture in less time than manual methods, permanent digital records of conditions, ability to measure complex shapes difficult to measure conventionally, and detection of fabrication deviations before installation. Integration with design software enables automated quality verification.
