Monitoring surveys involve the systematic observation and measurement of movement, settlement, or deformation in existing structures and infrastructure.

These surveys are typically conducted over extended periods, allowing engineers and stakeholders to track gradual changes that may not be immediately visible.

The primary purpose of monitoring surveys is to evaluate the structural integrity of buildings, bridges, tunnels, dams, and other critical infrastructure, ensuring they continue to perform safely and efficiently.

By detecting early signs of stress, subsidence, or displacement, these surveys enable proactive risk management, inform maintenance and repair strategies, and help prevent catastrophic failures.

Modern monitoring often incorporates advanced technologies such as laser scanning, GPS, total stations, and remote sensors, which provide high-precision data and allow for continuous, real-time assessment of structural behavior under various environmental and operational conditions.
