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.

    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.

    Mineral Resource Assessments, Dorset

    Mineral Resource Assessments have been undertaken for three sites in close proximity to each other for the same developer on the outskirts of village near Poole, in Dorset, where minerals resource assessments are commonly required due to the quarrying of sand and gravel deposits. Ruddlesden geotechnical carried out site-specific desk-based assessments of the superficial and bedrock geology and potential mineral resources, including the study of geological maps and memoirs, historical data, nearby borehole records, site investigation reports and British Geological Survey Mineral Resource Information for Development Plans. The mineral resource assessments, which were undertaken at the pre-application planning stage, as part of the viability assessment, identified that deposits beneath two of the sites were unlikely to be quarried, whereas further work was required to assess the risks at the third site. This information was used by the developer to help prioritise the developments.
