Geotechnical Instrumentation refers to the various sophisticated instruments that are used to monitor geotechnical structures, sites, and the environment. Geotechnical Instrumentation and monitoring play a significant role in the success of any construction project.
Geotechnical Monitoring goes hand-in-hand with geotechnical instrumentation. For instance, whenever a structure is planned, a proper surveying of the construction site as well as the nearby site is carried out. Geotechnical Survey is essential to check the soil profile and groundwater level before constructing any structure.
Once the construction work begins, continuous real-time monitoring is carried out so that the structure is made as per the expectations. Even after the completion of the project, constant monitoring and geotechnical surveys are carried on to gauge the structural changes.
One such company is the Encardio Rite Group. Established in Lucknow, India in the year 1966, Encardio Rite Group is a World leader in safety monitoring providing geotechnical instrumentation, structural & environmental monitoring along with geodetic surveying solutions. Over the years, it has become an established brand for its specialized services with high-quality products and innovative online solutions.

During the design stage, instrumentation installed in the exploratory tunnels and boreholes gives information regarding the existing ground conditions which in turn helps in optimizing the design. The Geotechnical Investigation confirms the design and monitoring plan.
Long term geotechnical monitoring services during the operational stages of the tunnel ensures its safety, determining the effects of any natural calamity (like an earthquake) on its structural integrity. Geotechnical investigation for tunnels helps in planning and optimizing the maintenance schedules.
Advances in geotechnical instrumentation, surveying technologies and data transmission systems now make it possible to monitor these slopes conveniently and economically. Remote (near real-time) monitoring of slope movement and other parameters potentially affecting it can be a correct approach for risk mitigation in unstable or potentially unstable slopes.
However, the groundwater monitoring task becomes gigantic and expensive when the number of sites and parameters to be monitored increases. Automated monitoring systems are the best geotechnical software solutions that provide data from different parts of Country at a remote central location in near real time.
The collapse of a bridge is often preceded by a change in the tilt of affected areas. The comprehensive geotechnical instrumentation is effectively used to online monitor the different types of structures to give timely warning on impending danger. The purpose is to assist and inform the owner/designer/contractor/architect about the continued performance of structures under gradual or sudden changes to their state.
The main geotechnical problems affecting the performance is degradation of structure with age, undue settlement/tilt due to soil conditions or nearby construction activity, vibrations due to traffic, groundwater level, atmospheric conditions and movement of slopes in hilly areas etc. This may be reflected in abnormal changes in tilt and settlement values.
Monitoring of a dam is essential to understand the foundation and structural behaviour both during construction and operation of the dams. Geotechnical Monitoring Services and Instrumentation plays a key role in safety monitoring for dams and people, providing necessary information on performance of the dam and detecting problems at an early and preventable stage.
The geotechnical survey scope of work and nature of instrumentation depend not only on the complexity of the dam and size of the reservoir but also on the potential for loss of life and property downstream. This information is critical for the dam owner who is directly responsible for any consequences of a dam failure.
A wide variety of instruments are used to carry out the geotechnical monitoring, geodetic surveys, structural monitoring, as well as, environmental monitoring. The most common geotechnical instrumentation provided by Encardio Rite includes:
The heart of the online structural monitoring instrumentation systems is the Data Collection and Transmission Service offered by Encardio Rite to users anywhere in the World. Encardio Rite offers Data Loggers with GPRS/GSM Transmission, Data Loggers with RF Transmission, Nodes, and Gateways, Readout Units, and Control Box.
This was all about the geotechnical monitoring and instrumentation along with the different services, solutions, and types of instruments used while monitoring. We hope that you found this information pretty useful.

Real-time monitoring of civil infrastructure provides valuable information to assess the health and condition of the associated systems. This paper presents the recently developed shape acceleration array (SAA) and local system identification (SI) technique, which constitute a major step toward long-term effective health monitoring and analysis of soil and soil-structure systems. The SAA is based on triaxial micro-electro-mechanical system (MEMS) sensors to measure in situ deformation (angles relative to gravity) and dynamic accelerations up to a depth of one hundred meters. This paper provides an assessment of this array's performance for geotechnical instrumentation applications by reviewing the recorded field data from a bridge replacement site and a full-scale levee test facility. The SI technique capitalizes on the abundance of static and dynamic measurements from the SAA. The geotechnical properties and constitutive response of soil contained within a locally instrumented zone are analyzed and identified independently of adjacent soil strata.
Additionally, losses associated with failures of soil systems continue to grow in the United States and elsewhere in view of increased development in hazard-prone areas. The control and mitigation of the effects of these failures requires a better understanding of the field response of soil systems. In order to overcome these problems, the performance of these systems needs to be reliably predicted, and such predictions can be used to improve design and develop efficient remediation measures. The use of advanced in situ monitoring devices of soil systems, such as the shape acceleration array (SAA) system described in this paper, and the development of effective system identification and model calibration is essential to achieve these goals. 2b1af7f3a8
