Rolls-Royce, Project Plateau – Geo-Environmental ConsultancyDerby

Construction of a development comprising the erection of a new building (15,000sqm footprint) providing workshop space (portal frames with cranes) and a first floor office / laboratory on the side. The new building is to be used for the design, assembly and dis-assembly of Civil Large development engines.

Within the Sinfin D-Site, Rolls-Royce intends to develop Project Plateau, which will provide a new flagship workshop / office / laboratory building with a footprint of approximately 15,000sqm. At the time of the investigation the Project Plateau Site comprised a large macadam-surfaced car park across the centre of the site. The footprint of the proposed building extends partially into building 9016 Nuclear Primary Components which is a manufacturing facility used by Rolls-Royce Nuclear. In the western part of the site the proposed building extends across buildings 9030 and 9031 which have various users including Rolls-Royce Manufacturing Services, Avis and Mitie.

A multidiscipline team at Ridge was appointed to deliver the project. The Geo-Environmental works comprised preparation of a desk top study which included historical, geological and environmental data.

The investigation incorporated 15 windowless sample boreholes, and four rotary boreholes. It also involved laboratory testing of representative samples for chemical and geotechnical parameters, the installation of six gas / water monitoring standpipes, and gas and groundwater monitoring.

Based on the findings of the investigation a ground condition assessment was prepared which detailed the findings of the investigation, testing and monitoring and made recommendations for foundation, paved area and floor slab design, specification of buried concrete, infiltration drainage, remediation and waste classification.
