    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.

    BRE 470 Platform Design, Paignton

    A significant thickness of made ground and underlying soft clay soils was encountered during a geotechnical investigation, necessitating the use of piled foundations for a proposed residential development site in Paignton. To facilitate the piling works, a working platform was required. Ruddlesden geotechnical were commissioned to undertake design calculations to provide the thickness of the working platform required. Working platform thicknesses with and without geogrid reinforcement were calculated in accordance with BRE 470: Working Platforms for Tracked Plant. Ruddlesden geotechnical utilised the information obtained during the previous geotechnical investigation, avoiding the need for any further intrusive investigation.

    Pre-Purchase Phase 1 Contamination Assessment

    Phase 1 Contaminated Land Assessment for the proposed redevelopment of a brownfield site in Devon, as part of the pre-purchase appraisal for the construction of a new supermarket. The site had numerous historical industrial land uses, including an iron foundry, gas works and an engineering works, as well as documented evidence of historical contamination of the ground, associated with an adjacent gas works. The production of the Phase 1 was crucial to understanding the potential development (and cost) constraints at this site for the client, prior to purchasing, and formed the basis of the scope of works for the Phase 2 Contamination Investigation.
