Ruddlesden geotechnical


Piling Platform Design/ Crane Pad Stability Assessment

Using data from the original ground investigation or new in-situ testing, working (piling) platform designs and crane pad stability assessments can be undertaken.

Working platform design calculations are undertaken in accordance with BRE 470 to determine the thickness of the platform, depending on the material used, with and without the use of geogrid.

Depending on the requirements of the crane operator, settlement and bearing capacity calculations can be undertaken for the ground beneath the crane pads.

Case Study

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.
