Laser Scanning for Concrete Verification

This presentation shares the findings from a recent field study conducted in Santa Cruz, California, which evaluated the use of terrestrial laser scanning (TLS) technology for assessing concrete tolerance on construction sites. With a focus on advancing testing methods in line with industry standards, this study investigates TLS’s potential to serve as a reliable and accurate alternative for construction quality assurance. The study aimed to establish the precision of TLS as a test method for verifying concrete tolerance in accordance with ASTME-691-23. Additionally, it sought to quantify the bias of the TLS method by comparing the results to reference values obtained using a total station, the accepted standard method as per ASTM E177-20. By evaluating the performance of TLS against established standards and reference measurements, this study contributes valuable insights into the potential of TLS as a tool for concrete tolerance verification in the construction industry.
