SmartEye is the Development Bureau (DEVB) of the Hong Kong SAR Government’s in-house Co-supervision Platform (CSP) for smart construction management. It incorporates technologies including 4D LiDAR, 5G fusion bonding, and Generative AI / LLM, and features “Video of Point Cloud” for spatial data. The platform is designed for joint use by Works Departments, Consultants and Contractors, supporting digital co-supervision for “early detection, early follow-up and early resolution” of on-site issues, while helping users identify and prioritise areas for detailed site inspection.
The SmartEye management dashboard, AI analytics and related application- layer services are provided under separate Government arrangements and are not part of Ambit’s supply scope.

Ambit supplies the Fixed-Point 4D LiDAR field equipment under the fixed-point approach described in DEVB’s SmartEye Specifications, providing hardware, scheduled capture workflows, on-site edge processing, and LiDAR datasets for integration with the SmartEye.
Fixed-Point LiDAR System (4D LiDAR) scans the construction site and converts the point cloud data into colorized and georeferenced spatial data. Through computer processing and high-speed 5G fusion bonding technology, the on-site conditions can be turned into a full, stereoscopic view without delay, and presented on an AI-enabled management platform.
