Survey & Monitoring

Sterling delivers precision surveying and real-time monitoring services supporting infrastructure construction, asset performance tracking, and safety assurance during live rail operations. Our survey capabilities span control networks, as-built documentation, deformation monitoring, and track geometry surveillance, providing the spatial intelligence infrastructure owners need for confident decision-making.

We deploy tilt sensors for track geometry monitoring during construction activities beneath live rail environments, ensuring no impact to track alignment while works proceed. Sterling has monitored track conditions during 20 undertrack bore projects across Melbourne Metro rail corridor, demonstrating capability to protect critical infrastructure during high-risk third-party works.

Our surveying services integrate with digital capture technologies (laser scanning, photogrammetry, drone-based surveys) to provide comprehensive spatial datasets. This combination enables clash detection for design coordination, as-built verification against design models, and progressive monitoring to validate construction tolerances — reducing rework and accelerating project delivery.
