    Creative geotechnical photography

    Inspired by her surroundings at RHS Rosemoor, where she was carrying out the ground investigation for a new educational facility, and with one eye on the Ruddlesden geotechnical site photograph of the year competition, Catherine Greed got creative with her site photography recently, framing the dynamic sampling rig within the last of the summer flowers.

    Ground Investigation Report, Cornwall

    A Ground Investigation Report, fulfilling the requirements set out in BS EN 1997-2: Ground Investigation & Testing, was produced for an extension to a school in Dorset. The Ground Investigation Report (GIR) presented a factual record of the ground and groundwater conditions encountered, together with the laboratory testingresults, followed by a review of the ground profile and geotechnical parameters for foundation design. The Ground Investigation Report was issued promptly, shortly after the receipt of the laboratory testing results, less than three weeks after the completion of siteworks. Interim parameters for design were provided prior to the receipt of the laboratory testing results, based on field observations and in-situ testing results.

    Economical Recommendations Provided for Ground Floor Slab Design, Devon

    Ruddlesden geotechnical were commissioned to review historical site investigation data to form a ground model and provide guidance on the use of a ground bearing slab for a proposed warehouse for a regional wholesaler. Consideration was given to the bearing capacity of the subgrade, volume change potential of the soil, slope of the ground, groundwater table, ground aggressivity and the presence of non-engineered fill materials. To avoid the requirement for a suspended floor slab, it was recommended that the superficial shrinkable soils be removed and engineered fill be imported to support the proposed ground bearing slab.
