RPS provided Civil and Structural Engineering designs for a new development consisting of 286 three, four and five-storey apartments over a semi-basement.

Specialist works included negotiations with Network Rail to allow pipe jacking of foul sewer under the railway embankment. We also advised on stabilising the highway at the entrance to provide new adopted site access.

We worked with the Environment Agency regarding surface water outfalls, flooding and stabilisation of the east bank of the river to support a new adopted highway access.

This project had to comply with local Planning Policy D4 and the requirement for 10% renewables. This was achieved through the use of solar thermal roof panels.

The ground beneath the site was contaminated by prior use as a gas works. We liaised with the projects contamination specialists to develop the most cost effective remediation and foundation solution. Remediated soil was engineered to have a high CBR value so that it could be used directly as sub base for the non-adopted roads and parking areas. The material was also suitable as a piling mat without further measures being undertaken.
