Geotechnics Limited were commissioned to undertake a ground investigation to assess the ground conditions behind the four wing walls supporting the A38 at the Western Interchange near Liskeard, Cornwall and monitor any movements of the walls.
A 7.5km long relief road between Dorchester and Weymouth is currently nearing completion. The project required the construction of 18m high embankments and a new bridge over a main railway line. Monitoring of ground movements in such sensitive areas both during and following construction was needed to ensure that any problems could be identified at the earliest opportunity.
Currently under construction, the Weymouth Relief Road passes over a Victorian railway tunnel access shaft which extends vertically down to an active railway tunnel lying some 40m below the current ground level. Investigation was required to determine its location and backfill characteristics and hence to provide parameters for designing a shaft cap.
The three villages of Boscastle, Bossiney and Tintagel, located in an area of outstanding natural beauty on the North Cornish Coast, are currently being upgraded with a new combined sewage treatment scheme. A new treatment plant is being constructed half way between Boscastle and Tintagel at the hamlet of Trevalga, with 5 new pumping stations required to pull the sewage up from the villages, including a 120m hydraulic lift out of Boscastle.
The Government’s drive to increase the nation’s renewable energy capacity has led to an increased national demand for wind power and to a number of investigation projects by Geotechnics Limited from Scotland to the South West.
