Instrumentation can be provided for a site-monitoring program. This may be strain gauging for load monitoring of excavation support struts, or examining the stress profile along the length of a pile during a load test.
Other examples may be pore pressure monitoring for a slope stability study, or instrumenting a down-hole tool. Control of the tool may also be incorporated into the monitoring program.
