3D Laser Scanning Applications in Quantity Surveying

  • Allsteel Showroom 1725 I Street NW, Suite 550 Washington, DC 20006 (map)

The presentation will cover basic concepts in aerial and terrestrial laser scanning (Lidar), including acquisition, registration, alignment and segmentation, and demonstrate various applications of this data of specific interest in cost estimation and quantity surveying, including measurements directly from point clouds, automatic geometry extraction and surface modeling, using both commercial and open-source software. Several case studies in quantity estimation will be presented to provide practical guidance on the available approaches for estimation using this technology.
