    BRE 470 Platform Design, Paignton

    A significant thickness of made ground and underlying soft clay soils was encountered during a geotechnical investigation, necessitating the use of piled foundations for a proposed residential development site in Paignton. To facilitate the piling works, a working platform was required. Ruddlesden geotechnical were commissioned to undertake design calculations to provide the thickness of the working platform required. Working platform thicknesses with and without geogrid reinforcement were calculated in accordance with BRE 470: Working Platforms for Tracked Plant. Ruddlesden geotechnical utilised the information obtained during the previous geotechnical investigation, avoiding the need for any further intrusive investigation.
