Ruddlesden geotechnical

Ruddlesden geotechnical provides ground investigation, geotechnical consultancy and contamination assessment services.

Based in Exeter, but covering the whole of the UK, albeit primarily concentrated in the South West, Ruddlesden geotechnical was formed in 2004.

Ruddlesden geotechnical works on behalf of a wide client base, including local, regional and national housing developers, housing associations, commercial developers, building contractors, structural and civil engineers, architects, building consultants, quantity surveyors, local authorities and private individuals.

Development projects range from single dwellings and extensions to large housing estates, multi-storey flats, offices, industrial units, roads, slopes, schools, hospitals and basements.

The services and projects listed on this web-site provide an indication of those undertaken by Ruddlesden geotechnical, but others are carried out. If your requirement is not readily identifiable on this web-site, please contact us as we may still be able to help you.

    Coastal Slope Stability Assessment

    Geoff Davis has recently been in his element, carrying a slope stability assessment for a holiday park that has recently seen some quite dramatic ground movements.One thing that this project has highlighted is that for all the new technologies that are available to help us understand the ground, including LiDAR, drone surveys, remote sensing and inclinometers, all of which we intend to use on this site, they are of little use if the ground model is not understood. And this understanding of geology and geomorphology only come from a combination of education and experience.It is hoped that our understanding of the landslide processes at this complex site will allow us to predict possible future behaviour and assist in developing a long-term strategy for the future of the holiday park and its management.

    Pile Mat Design, Plymouth

    Geogrids were used as part of a pile mat design for a site in Plymouth. Calculations, which were undertaken in accordance with BRE 470: working Platforms for Tracked Plant, showed that a significant reduction in the platform thickness could be achieved if geogrid was incorporated into the platform construction, reducing the temporary works costs. Calculations were carried out for geogrids of varying tensile strength so that cost-benefit analyses could be carried out.

    Ground Conditions Chapter for Environmental Statement for Large Residential Development

    Ruddlesden geotechnical produced a ground conditions chapter for an Environmental Statement (ES) as part of the Environmental Impact Assessment (EIA) for a new, large residential development on the outskirts of Dawlish, Devon. Following the scoping assessment, which was agreed between Ruddlesden and the local authority, a Phase 1 Preliminary Geotechnical and Contamination Assessment was undertaken to provide information on the baseline ground conditions at the site. This information was used to assess how the proposed development would affect the ground conditions in the short term (construction stage) and long term (developed stage). Where the proposals were found to have a negative impact on the baseline ground conditions, mitigation measures were proposed to reduce the impact to acceptable levels.
