Point-Cloud Analysis: Overview

During the life of many buildings, both structural and non-structural components endure movement and deformation due to aging, construction, and geological shifts. Although the deformations and movements are not life-threatening, deficient design of the buildings and associated non-structural components could be costly in the long-run, and in order to ensure proper behavior of the superstructures, the non-structural elements should not be ignored. 

3D laser scanning and surveys of buildings while they are in service are becoming more common. The surveys allow engineers to quickly develop preventive maintenance plans, monitor the rate of deterioration, create analysis reports, and limit the possibility of catastrophic failure. Commonly, monitoring detects differential column shortening, lateral story drift, slab and beam deflection, thermal deformation, et al. As long as the inevitable movement and deformation of the structures are not ignored, and the proper, timely, preventive steps are taken, the costs can be limited. Aging, deformation, and movement are inevitable. 3D laser scanning is the most cost-effective tool to monitor large structures and lower remediation costs.
