A reliable PBM and a robust control network are the foundation of high-accuracy surveying.
By integrating GNSS, Total Station, Drone, and LiDAR data within a unified reference framework, it ensures maximum accuracy throughout design, construction, and monitoring. Permanent control points are also essential for long-term deformation and displacement monitoring of railways, MRT systems (elevated & underground), bridges, dams, and high-rise structures.
A well-established PBM is not just a technical requirement—it is the cornerstone of every successful mega infrastructure project.
