    Mini golf in a Cornish rock garden

    A bit of rain did not dampen the spirits at the Ruddlesden geotechnical golf day this year, when retaining the trophies became the theme of the day.Smashing balls into a field in Cornwall (Trackman driving range) was followed by lunch in the feasting barns, with the main event – mini golf in a Cornish rock garden – in the afternoon. Geoff and Sarah retained their first male and female prizes, Becky put a lot of effort in hanging on to her wooden spoon trophy, and Catherine won the nearest the pin trophy for the first time. As always, there was no winner of the ‘beat-the-boss’ prize, but this year that was only because having the same score does not mean beating!

    Mining Supervision, Somerset

    Following a coal mining risk assessment, which indicated the proposed residential development site in Kingswood, Bristol, to potentially be at risk from historical coal mining, a geotechnical investigation was undertaken to ascertain the depth (and thickness) of any historical mine workings. The geotechnical investigation and updated coal mining risk assessmentindicated that remedial works were required to guarantee the safety of end users and serviceability of the structures, as the shallow depth of the historical workings meant that the site was at risk from crown-hole collapse. As construction works had already commenced, the only option to avoid the demolition of the newly built houses/ flats was to consolidate the mine workings, to remove the risk of collapse. Ruddlesden designed the remedial works, which comprised a number of boreholes on a fixed grid surrounding the footprint of the part-constructed building, and appointed a specialist contractor to undertake the grouting. Ruddlesden geotechnical supervised the remedial works throughout and signed off the works on completion.

    Supervision of Contamination Remediation of Former Petrol Filling Station

    Ruddlesden geotechnical recently supervised the contamination remediation works for residential development of a former petrol filling station site in Exeter. Ruddlesden supervised the excavation of the underground fuel storage tanks, pipelines and interceptors, as well as grossly contaminated soils. Validation testing of the resultant excavations was subsequently undertaken, to demonstrate that no unacceptable levels of contamination remained in the ground. Groundwater quality monitoring in borehole installations was also undertaken before, during and after the remedial works, to assess the risks to controlled waters and a betterment of groundwater quality. Close liaison throughout the works with the local authority and Environment Agency, ensured that the regulators were satisfied with the works and all the relevant planning conditions were discharged.
