Slopes - M25 Godstone

Instrumentation (installation, monitoring and reporting)
Status: Current

In late 2002 Geotechnical Observations were commissioned to assist in the investigation of slope movements adjacent to the M25 motorway in Surrey. In March 2003 we supervised the installation of inclinometers and GeO piezometers.

GeO read and review the inclinometer data at weekly intervals and report any unusual events to directly to the maintaining agent. Datalogged pore water pressures are downloaded every month and an interpretive report is written.

Significant movements have been detected and are now being closely monitored using an in-place inclinometer system that is linked via a GSM modem to our offices.

A Working Group with representatives from the Highways Agency, Mouchel Parkman and Geotechnical Observations meet at regular intervals to review the data.
