Monitoring of Structural Settling

Engineering companies and contractors are facing challenges never before experienced. They are being charged with – and being held liable for – the health of the structures they create and maintain. In order to surmount these challenges, engineers need to be able to measure structural movements to millimeter-level accuracy.

Accurate and timely information on the actual status of the structure is highly valuable to engineers, enabling behavior of the structure against the design and theoretical models. When empowered by such data, engineers can effectively and cost efficiently measure and maintain the health of these vital infrastructures.

Numerous accidents and disasters in the past have shown the risks that are associated with large construction projects (e.g. dams, tunnels, bridges, high-rise buildings, etc.) or natural events (e.g. volcanoes, landslide and settlement areas). The monitoring of manmade structures and dangerous areas is becoming increasingly important. Monitoring involves periodically and automatically measuring points in or around an active area to determine the deformation.

It is often necessary to immediately analyze the measured data and to inform the responsible people when movements exceed set tolerances. Monitoring and deformation analysis present some of the most sophisticated challenges in the surveying industry today because they require the highest accuracy, maximum reliability, automatic measurements and advanced computation and analysis.

Why is NYCLS the best choice for your monitoring project?

  • We help to reduce cost and risk.
  • We provide 24 hours, 7 days a week monitoring of critical man-made structures and natural phenomenon.
  • We are flexible and scalable to match your needs.
  • System is simple to install and easy to use.
  • System is an integrated solution that supports total station, GNSS, levels, Dataloggers and geotechnical sensors for an overall understanding of structural movements.

Cost Reduction

The ability to detect and react to potential problems before they develop will help in the reduction of insurance costs and the prevention of catastrophic failures that may result in injury, death and huge financial loss. Additionally, a structural monitoring system will help reduce both your current and long-term maintenance costs associated with structural movement.

Risk Reduction

With a structural monitoring system, risks are reduced as data analysis can be used to more fully understand the current and future implications of structural movements. Both safety and structural integrity concerns can be minimized. Contractors can reduce their risk exposure before, during, and after a construction project by continuously monitoring the project as it progresses through its lifecycle. Potential problems can be spotted early on and a step taken to rectify the situation before a critical situation develops.

Whether you need to monitor subsidence and settlement prior to construction, the impact of tunneling on nearby buildings, the movement of a slope due to erosion, or movement of a bridge due to aging and corrosion of materials, NCYLS surveys will provide a solution.

Our main areas of focus are concentrated within structural monitoring which includes the following categories:

  • Construction sites
  • Roads
  • Dams
  • Tunnels
  • Bridges and Viaducts
  • High-rise and historical buildings
  • Foundations
  • Mines
  • Settlement areas

Engineering structures (such as dams, bridges, high-rise buildings, etc.) are subject to deformation due to factors such as changes of ground water level, tidal phenomena, tectonic phenomena, etc. Cost is more than offset by savings and by improvements in safety both during and after constructions. As a result, the design, execution and analysis of such surveys are a matter of considerable practical importance. Expanded resource development, the trend towards potentially -deformation-sensitivity engineering and construction projects, and growing geoscientific interest in the study of crustal movement have all combined to increase awareness of the need for a comprehensive integrated approach to the design and analysis of such deformation surveys. Deformation refers to the changes of a deformable body (natural or man-made objects) undergoes in its shapes, dimension and position. Therefore it is important to measure this movements for the purpose of safety assessment and as well as preventing any disaster in the future.


Each monitoring project has specific measurement and accuracy requirements. Our GeoMoS software provides a highly flexible monitoring system that is able to combine geodetic, geotechnical and meteorological sensors to match the needs of your monitoring project.

Powerful event management and messaging capabilities can be used to notify responsible staff about important system events, e.g. limit exceeded, power failure, burglary, communication to sensor lost etc. Coordinates and displacements are computed in your local geodetic system and the output of one or more sensors can be modelled with constants, mathematical functions and/or logic operators as a so-called ‘virtual sensor’.

Access your monitoring project anywhere, anytime and quickly get an overview of the system status or make detailed analysis of the data. The Site Map shows at a glance the status of your monitoring project using traffic light symbols overlaid on a photo or georeferenced map.
