TSS Project Overview - Museum Station Water Damage & Surface Scan, Sydney CBD.
Our scanning team recently completed a comprehensive laser scanning survey at Museum Station in Sydney’s CBD, delivering a high-accuracy digital record of water-damaged areas within the underground station environment. Using a combination of Trimble X7 scanners and the Trimble SX12, the project focused on capturing detailed spatial data to support assessment, analysis, and future design works.
The scope of works was designed to ensure complete coverage of both underground and surface assets, including:
Scanning of main station stairways and connecting pedestrian tunnels
Detailed capture along train platforms
Documentation of visible water damage and moisture staining
Surface scanning near the station entrance to identify visible services within the surrounding footpath
This approach produced a comprehensive and highly detailed point cloud dataset representing both structural conditions and service locations.
Conducting laser scanning within an active public transport station presented unique operational challenges. With high commuter volumes, particularly during peak hours, our team maintained constant situational awareness while ensuring safe, efficient, and uninterrupted data capture. The ability to operate seamlessly in a live environment highlights both the flexibility of the technology and the experience of our scanning team.
Accurate survey control was established by Eyad using the Trimble SX12, ensuring the dataset was precisely referenced and ready for downstream engineering and design applications.
Key technology highlights included:
HDR imaging on the Trimble X7, enabling clear identification of water damage and moisture staining in low-light underground conditions
Use of a Leica BLK scanner for rapid infill scanning, ensuring no areas were missed and full site coverage was achieved
An unexpected but rewarding aspect of the project was the public’s interest in the scanning process. Many commuters were curious about the equipment and took the opportunity to learn more about laser scanning and its capabilities—an encouraging reminder of the growing visibility of geospatial technology in everyday infrastructure projects.
