PROJECT PROFILES: INDUSTRIAL AND COMMERCIAL

Fareham Reach, Gosport, Hampshire

A large light industrial development was proposed for this site adjacent to the harbour and underlain by deposits of the London Clay. Some of the new buildings were to be located in an area previously affected by a dense cover of mature trees. In such situations it is often necessary to use suspended ground floors as a precaution against significant ground heave following tree removal. However, for economic reasons, the use of ground bearing floor slabs was the preferred option.

A ground investigation was carried out in 2 phases, the initial phase comprising trial pits and boreholes to determine the soil profile and provide general foundation design advice. The second phase of investigation included obtaining undisturbed samples and undertaking specialist soil suction testing in order to enable the potential for soil heave with changes in moisture content to be estimated. Analyses based upon the results of the investigation showed that the use of lime and cement soil stabilisation could be specified for the improvement of the weak clay subgrade, for both pavement and floor slab constuction, and to limit the potential for ground heave to acceptable levels.

Silvertown, London

A mixed commercial and housing development was proposed for the site of an industrial estate in London’s Docklands. Ashdown Site Investigation undertook a geotechnical and geo-environmental ground investigation of the estate whislt it was still in operation. Ashdown staff liaised closely with the occupants to ensuring that minimal disruption to their activities occurred during the course of the investigation.

The investigation included a detailed desk study and risk assessment of historic land use to establish the risks to the proposed development and surrounding area of past and proposed activities on the site. The intrusive investigation included the excavation of boreholes by both window sampler and cable percussion techniques, together with the installation and monitoring of standpipes to assess groundwater and gas conditions. A combined Contamination Risk Assessment and Geotechnical Interpretative Report were prepared for the proposed development.

Littlehampton, West Sussex

Ashdown has been involved with the investigation of numerous phases of this large development of warehouses, offices and production facilities for a nationally known retailer. The developments were located on greenfield sites and investigations have been designed to provide advice for the design of foundations, ground floors, and road pavements. The company was also commissioned to undertake the detailed design and installation of borehole soakaways at several locations on the development.
