EdlingtonAs part of the Governments drive to get the Nations children back to school, ECG have been undertaking geotechnical assessment for facilitating the installation of a new modular classroom facility at a school in Huddersfield.
A temporary crane is needed to lift the structural segments into position and an existing area of playground hardstanding has been set aside for this purpose. ECG were commissioned to undertake a series of UKAS accredited Plate Load Tests at the intended crane outrigger locations to assess the response of the pavement under short-term concentrated loading in order to inform the crane lifting specification and risk assessment.
The testing simulates the working dynamic load conditions experienced by the ground beneath the crane outriggers by jacking a plate onto the ground using an excavator as kentledge. Deflections in the plate are measured against a fixed reference datum for incremental loading stages allowing an assessment of the Modulus of Sub-grade Reaction, California Bearing Ratio and Allowable Bearing Capacity of the ground to be assessed.
