    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.

    Dynamic Sampling was Preferred Method of Investigation in Devon

    Dynamic sampling (windowless sample boreholes) was utilised in a scheme of works for the proposed stabilisation and reinstatement of a quay wall. This was the preferred method for the initial geotechnical investigation at this site, as they allowed representative samples of the near surface soils to be obtained, facilitated Standard Penetration Tests (SPTs) and were able to be progressed down to depths of 6m-8m to determine the presence of engineering rock-head, all whilst keeping site disturbance and the areal extent of the site works to a minimum, allowing the adjacent car park to be in continued use without the need for closure. On completion of the ground investigation, the boreholes were either installed with monitoring wells, to facilitate long-term groundwater and/ or ground gas monitoring, or backfilled with natural arisings prior to reinstatement.

    Earthworks Specification, Devon

    Following a materials suitability assessment, Ruddlesden geotechnical produced an earthworks specification for the proposed material movements at a residential development site in Paignton. The specification summarised suitable and unsuitable materials present (based on the findings of the materials suitability assessment) and provided details of how to excavate, stockpile and deposit the materials. Guidance on the testing requirements (to confirm the material was suitable for placement/ conformed to those suitable materials detailed within the specification) was also provided. Ruddlesden geotechnical also carried out the earthworks testing for this project.
