Instrumentation and monitoring

Instrumentation and measurement techniques are increasingly used to monitor construction works, processes, and infrastructure during construction and operational phases, verify design and engineering, and detect incidents to reduce risk.

NGI has cutting-edge expertise in instrumentation, sensor technology, and underwater technology. Our ability to innovate, experience, and understand physical and mechanical processes help us see and foresee our client's challenges and thus optimally assist them.

Top expertise

• instrumentation technology and choice of sensors and measurement methods to monitor physical and mechanical processes
• development of measurement systems, data transfer, analysis, and presentation, as well as warning technology
• knowledge of the behavior of geo- and building materials, natural hazards, pollution, and climate conditions

Use of Instrumentation and Monitoring

Instrumentation is often used to monitor construction processes and the lifecycle of structures. Examples include extensive instrumentation of embankment dams in Norway, large bridges, and offshore platforms and installations.

Major groundworks can uncover unexpected ground conditions, as well as risks of ground failure and instability in surrounding areas. The installation of sensors to monitor the situation and detect the development of unwanted conditions is increasingly common.

The measurement systems are operational from the construction and installation phase, and can also be used to monitor structures throughout their entire lifetime, under all types of weather conditions.

Examples of what can be measured and monitored

• water pressure in the ground (pore pressure)
• forces, pressure, and deformations on structures and in the ground
• natural hazards or movements resulting from vibrations and landslides
• contamination in soil and groundwater
• vibrations and noise from transportation
• local weather and climate conditions
• specialized investigations of soil and rock conditions
• gas leaks from and on the seabed
• precise surveying of pre-installed foundations, enabling structures to be manufactured with exact dimensions to fit the foundation

New Technology, New Opportunities

New technology continuously pushes the boundaries of what can be measured and monitored, and how measurement results can be used to send alerts or initiate or stop processes.

In recent years, it has become possible to transmit measurement data wirelessly and to collect data from satellites. NGI’s multidisciplinary and complementary team within instrumentation and monitoring continuously develops new systems to assist clients with their challenges.
