Assessing Steel Bridges Structural Condition using Light Detection and Ranging (LiDAR)

For this research project, our team investigated the application of LiDAR-based technologies in steel bridge maintenance and inspection. The project focused on the steel bridge that spans Highland Dr, located on Cal Poly's Campus. Using terrestrial laser scanning and software like Scene and CloudCompare, we were able to register scans and compare point clouds. We also worked on the point clouds in MATLAB, with the ultimate goal of being able to generate an as-built BIM.

We would like to thank the personal donors and Cal Poly’s College of Engineering for funding this project and allowing us to explore this industry relevant research.

Final Thoughts

We are grateful for the opportunity to work on this project and the support that we have received from the College of Engineering through this program. We believe that there is potential for real development to be made in this area of construction engineering. We hope to continue working towards automatic generation of as-built building information models in the future.
