Wilsthorpe Community School is secondary comprehensive school in Long Eaton, Derbyshire. Work on this school was delivered as a part of Priority Schools Building Programme phase 2 (PSBP2) on behalf of the Education and Skills Funding Agency.
This new education facility is located on the existing school site, which has remained live throughout the construction phase. Delivering services to the new site proposed phasing issues as the infrastructure had to be designed to feed the new and old buildings.
Geotechnical and geoenvirionmental assessments previously carried out by others on behalf of the EFSA indicated gas protection measures would be required to be incorporated into all new structures, no data was provided to enable the design of sustainable drainage solutions, extremely conservative recommendations had been made for foundations and no assessment of waste soils had been made.
This resulted in scheme costs potentially impacting the viability of the scheme. To assist the Client, Cundall scoped, managed and reported on a ground investigation that specifically addressed these information gaps.
The outcome of this investigation resulted in the elimination of the need for gas protection measures at the site leading to reduction in scheme cost, the provision of enough information to allow effective and economic SuDS design, the provision of more economic foundation recommendations resulting in significant cost savings and provision of a detailed waste classification assessment of surplus soils.
The above recommendations not only ensured the viability of the scheme but also resulted in reduced scheme cost and much greater certainty with respect to abnormal ground risk.
