3D Laser Scanning

Orbital Engineering recently completed 3D laser scanning services for a customer in order to address structural integrity issues with the waste heat stacks at four of their facilities in the U.S. The 3D laser scans were utilized to determine if foundation settlement issues had resulted in unacceptable lean of the waste heat stacks and also to determine if any deformations exist in the waste heat stack cylindrical shell plate. A two man team utilized a Faro Focus 3D Laser Scanner with a 305 degree vertical and 360 degree horizontal field of view to create a detailed three-dimensional image of the waste heat stacks and associated structures. The three-dimensional image created by the scanner is an assembly of millions of 3D measurement points that provide an exact digital reproduction of objects within the scanner’s field of view. A range of fifteen (15) to twenty (20) individual scans were taken at each waste heat stack in order to capture all portions of the structure including areas with obstructions. The individual scans were combined to form a three-dimensional image of the waste heat stack area utilizing portable targets in the field and computer software in the office.

Computer software was also utilized to cut several sections through the three-dimensional image in order to better interpret the scan results. Vertical sections were cut through the stack in order to determine the amount of stack lean. Horizontal sections were cut through the stack at several elevations in order to determine the amount of deformation in the cylindrical stack shell plate. The results for each waste heat stack were compiled in a report along with sketches in order to present the findings to the customer.
