New Slipway, River Dart
Red Rock have considerable experience in ground investigations on quaysides and over water.
These projects require detailed logistical planning to co-ordinate the barges and drilling rigs, and also to obtain the necessary permits from the port authorities and Marine Maritime Organisation. We have been involved in projects for quay repairs, new quays, slipways and structures over water.
At Dartmouth Lower Ferry, Dartmouth, Red Rock undertook over water investigations from a barge to provide design data for the extension of the slip way at the Lower Dart ferry. The investigations were restricted by tidal flows and access requirements to allow ferry operations to continue during the drilling.
Red Rock have experience of investigations around the harbours and quays of Plymouth for over the last 20 years. Other similar investigations included Boardwalk, Sutton Harbour, Plymouth, where we were commission to undertake investigations for a new commercial development and walkway on piled structures over Sutton Harbour. Red Rock carried out intrusive investigations from a pontoon barge to provide rock quality data for pile design. Soil sediment samples were also obtained to provided a geo-environmental assessment of the potential risks due to sediment disturbance from piling. Our environmental assessment was used to obtain the Marine Management Organisation (MMO) licence for the piling works.
