    Geoff’s birthday treats!

    We recently celebrated a special birthday of Geoff Davis, in a place that is close to his heart: the East Devon coast.He treated us to his knowledge of the geology and landslide systems in the area, and we treated him to an ice cream on the beach!

    Boreholes for Retaining Wall, North Devon

    To aid the design of a large retaining wallat a former glove factory in North Devon, Ruddlesden geotechnical were commissioned to undertake a geotechnical investigation to provide information on the ground conditions. Combined percussive and rotary drilling was undertaken, to obtain sufficient samples of the near surface soils and deeper rock materials, which could not be readily sampled using percussive or rotary methods in isolation. Cost (and time) savings were made by only mobilising one drilling rig, rather than have undertaken separate phases of investigation for the sampling of soils and rock materials.

    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.
