New Eastern Villages – Southern Connector Road

Download our Factsheet

Project Summary

New Eastern Villages, Swindon, will consist of 8,000 homes, new schools, employment spaces and community and leisure facilities located to the east of Swindon. It is estimated to span @700 hectares, with its eastern boundary reaching the point at which the River Cole meets the A420.

To allow the development to progress, several highways improvement schemes were required including the provision of a Southern Connector Road.

CC Ground Investigations Limited (CCGI) acted as Principal Contractor to Swindon Borough Council to undertake the ground investigation under the technical direction of the Engineer, Atkins Limited, to assist with the design of the new road.

Project Details

Fieldwork activities were carefully programmed to minimise any disruption to landowners. Additionally, some of the works were carried out within traffic management, including during nighttime shifts. The work was carried out over an approximate linear length of 4.5km of agricultural, commercial, and residential land. CCGI’s role included liaising with various landowners and providing a detailed programme ahead of the intrusive investigation. To enable these works to be carried out a number of extra activities were required including de-vegetation works with ecological supervision, the provision of acoustic barriers, archaeological supervision and provision to allow for soft ground due to working within a flood plain.

The works were carried out using in-house drilling rigs including our multi-purpose rigs, dynamic sampling rig. All works were supervised on a full-time basis by suitably qualified Engineering Geologists, with logging carried out to BS5930: 2015+A1:2020 and BS EN ISO 14688 [Parts 1 and 2] and BS EN ISO 14689:2017.
