Deep excavations

What is deep excavations monitoring? Deep excavation monitoring refers to the process of measuring and analysing the behaviour of soil and structures during excavation works in order to ensure safety and stability. It is important to monitor deep excavations because the excavation process can cause changes in the stress and strain of the soil and […]

TBM Tunnels

What is TBM tunnel monitoring? A TBM tunnel (Boring Tunnel Machine) is a tunnel that is build using a massive tunnel drilling machine. During the excavation process, the TBM removes the excavated material from the tunnel face, transports it to the back of the machine, and then transports it to the surface using a conveyor […]

NATM Tunnels

What is NATM Tunnel monitoring? The New Austrian Tunneling Method (NATM), also known as the Sequential Excavation Method (SEM), is a technique used in the construction of tunnels that was developed in Austria in the 1960s. NATM involves excavating the tunnel in stages, with the surrounding rock or soil providing temporary support until a permanent […]

Dams rehabilitation

WHAT IS THE REHABILITATION AND MODERNIZATION OF MONITORING SYSTEMS IN DAMS? Dams are critical infrastructures designed to manage water resources and produce electricity, many of which have reached the end of their useful life or may require extensive rehabilitation. In 2021, UNU-INWEH (United Nations University – Institute for Water, Environment and Health) published a report […]

Concrete dams

WHAT IS Concrete DAMS MONITORING? Concrete dams are typically constructed using reinforced concrete, which is a strong and durable material that can withstand the weight of the water and the pressure of the reservoir. Concrete dams can be designed and built in a variety of shapes and sizes depending on the specific requirements of the […]

Embankment dams

WHAT IS EMBANKMENT DAMS MONITORING? An embankment dam, also known as a fill dam, is a type of dam that is constructed by building a long, narrow embankment made of compacted earth or other materials across a river or other watercourse. The embankment is designed to hold back water and create a reservoir behind the […]

SHM – Structural health monitoring

SHM – Structural health monitoring What is SHM – Structural health monitoring? Structural Health Monitoring (SHM) is a process of continuous or periodic monitoring of the condition of a structure to detect any changes in its properties or behaviour that may indicate the onset of damage or failure. In the context of structural engineering, SHM […]

Mines and tailings dams

What is mines monitoring? Mines geotechnical and structural monitoring refers to the practice of using various technologies and techniques to monitor and analyse the stability and integrity of mine structures and the surrounding rock formations. This type of monitoring is crucial to ensure the safety of workers and to prevent accidents such as mine collapses […]

Railways

Railways What is railways monitoring? Railway deformation monitoring focuses on detecting and monitoring any changes or deformations in the railway infrastructure. This can include the track, the ballast, the subgrade, and other components of the railway system. Deformations can occur due to a variety of factors, such as changes in temperature, heavy train traffic, or […]

Bridges and viaducts

What is bridges monitoring? Bridge monitoring refers to the process of continuously monitoring the performance and condition of a bridge to ensure its structural integrity and safety. This is done by installing a network of sensors that can provide nearly-real-time data on the bridge’s health and performance.The sensors and monitoring systems can measure a variety […]

Buildings and heritage

What are buildings and heritage monitoring? Building, skyscraper, and heritage monitoring refers to the process of regularly observing and recording the structural integrity of these structures. This is done to ensure that they remain safe and secure for their occupants and visitors, and to identify any potential issues or areas that require maintenance or repair. […]

Landslides

Landslides What is landslide monitoring? Landslide monitoring refers to the process of monitoring the stability of slopes and identifying potential landslides. It involves the use of various techniques and instruments to continuously monitor the behavior of slopes and detect any signs of instability. Landslide and slope stability monitoring typically involves installing sensors, such as inclinometers, […]
