    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.

    Assessment of Groundwater Pressures Critical for Retaining Wall Design

    Long-term groundwater level and pressure monitoring of standpipe piezometers installed in rotary boreholes was undertaken to provide information for the design of a new retaining wall for a school in Dorset. Groundwater pressures were considered to be a key reason for the failure of the existing wall, which appeared to have inadequate drainage and so it was critical that groundwater levels and pressures, and their seasonal fluctuation, were understood for the design of the replacement wall.

    Water Supply Pipe Assessment for Residential Development

    Ruddlesden geotechnical were commissioned to undertake a preliminary site assessment report for water supply pipe selection at a proposed residential development site in North Devon. The desk study indicated that the site had had no previous development and had not been used for the storage of fuels or chemicals. The report, which was undertaken in accordance with UKWIR guidance, concluded that no special requirements were required for water supply pipes at this site.
