We delivered geotechnical temporary works designs for a complex project involving crane erection and the replacement of a railway bridge over Creek River, Kent. The designs included a temporary site working platform, a temporary bridge abutment, and a temporary ramp access for Rail-Road Vehicles (RRV).
The project faced significant challenges due to poor subgrade conditions, with an undrained shear strength of just 10 kPa, making standard BRE 470 design calculations unsuitable. For subgrade conditions with undrained shear strength below 20 kPa, the Tensar T-value method was employed to determine the required thickness of the working platform. This solution provided a stable and safe working environment while being non-invasive to the surrounding cropland, ensuring minimal environmental impact.
