Abstract

Developments of Terrestrial Laser Scanning (TLS) and Building Information Modeling (BIM) offer great opportunities to achieve a leap forward in the efficiency and completeness of dimensional control operations. This paper presents an approach that demonstrates the value of this integration for slab flatness control. The approach first employs the Scan-vs-BIM principle of [5] to segment TLS point clouds and match each point to the corresponding object in the BIM model. It then automatically applies the Straightedge technique to the TLS points associated with each floor slab, and concludes with regard to their compliance with given tolerances. The approach is tested using data from two real concrete slabs. Results validate the performance of the proposed system when compared with traditional measurements methods. A novel straightedge generation method is also proposed and demonstrated that enables more complete and homogeneous analysis of surface flatness for insignificant additional processing times.
