    Start over-winter monitoring before it is too late!

    Look at these groundwater monitoring dataloggers! Whilst some loggers are still in the ground, monitoring groundwater levels all year round, these lot were taken out of their boreholes in May or June this year, once they had proven that they had recorded the seasonal groundwater peaks.As we come towards the end of a particularly dry summer, it might seem difficult to think about monitoring groundwater levels when conditions are at their wettest. But there is considerable benefit in starting over-winter groundwater monitoring sooner rather than later.. One year, the seasonal groundwater peak will be in November, and if the loggers don’t go in the ground before then, they won’t be able to record this!With Ruddlesden geotechnical, there is no financial benefit in delaying the start of over-winter groundwater monitoring; we charge the same to start monitoring in September as we do in December

    Plate Bearing Testing for Wind Turbine, Devon

    Ruddlesden geotechnical have recently undertaken plate bearing testing at a number of farms in Cornwall to validate geotechnical parameters, provided as part of a previous geotechnical investigation, used in the design of the wind turbine. Ruddlesden geotechnical liaise with the client and construction team to undertake the testing as soon as excavation is complete, to ensure the ground to be tested is relatively undisturbed, representative and as not to delay the construction phase. Careful planning can allow other aspects of wind turbine construction, including crane pads and track ways, to be validated, to save time and ultimately construction costs.

    Correct Waste Classification Saves Costs

    Waste classification was undertaken on surplus soil at a residential development site in Exeter. The soil had been purchased and imported to be used as capping beneath road surfaces for the new development. However, the material was later found to be unsuitable for the proposed use. The soil had initially been classified by others as hazardous waste, due to the presence of loose asbestos fibres within the soil matrix. However, following intensive (and representative) sampling of the soil stockpiles, Ruddlesden geotechnical were able to confirm that the soil was non-hazardous waste. Classifying the waste properly, in accordance with Environment Agency guidance, saved the client significant costs, which would have been incurred if the soil were to have been taken to a hazardous waste landfill, as was originally proposed.
