Short summary
Completeness checking of constructional steel structures with several hundred weld-on parts still represents a great challenge. By the use of 3-D scanners, it is possible to obtain sufficiently comprehensive information about the actual configuration (as-is state). By using an adapted algorithm for post-processing of the resulting point clouds, difference figures are superimposed over the respective 3-D model as the target state. The difference figures signal the missing parts.
