Instrumentation and monitoring plays a vital role in any civil engineering project. Instruments are used to characterize initial site conditions. Common parameters of interest in a site investigation are pore-water pressure, permeability of the soil, and slope stability. Instruments are used to verify design assumptions and to check that performance is as predicted. Instrument data from the initial phase of a project may reveal the need (or the opportunity) to modify the design in later phases.Instruments are used to monitor the in-service performance of a structure. For example, monitoring parameters such as leakage, pore-water pressure, and deformation can provide an indication of the performance of a dam or in slope. Monitoring loads on tieback anchors or rock bolts and movements within a slope can provide an indication of the performance of a drainage system installed in a stabilized slope.We can provide and install a range of instrumentation which may be required to facilitate sampling and/or monitoring of groundwater, ground movements or a combination of these.
Typical instrumentation includes:
