Chemically Stabilised Piling Platform – Goodluck Hope

The design of an OPC stabilised piling mat to support various piling rigs at the Goodluck Hope project in East London.

The Goodluck Hope Project was a riverside regeneration project to create 841 homes, 2,300sq m of commercial space, 250sq m of education floorspace and a restored Grade II-listed Orchard Dry Dock.

Additional Benefits Of Chemically Stabilised Piling Platforms

In addition to the ability to support the required working platform loadings. The use of OPC chemically stabilised piling platforms can have the following benefits to the scheme.

  • Reduced overall mat depth
  • Limited mucking away
  • Limited import of materials 
  • Creation of an impermeable layer

These benefits can help contribute to more effective and efficient construction schemes by reducing time, materials and carbon footprint required to complete the scheme.

Platform Ground Profile

This image compares the engineering drawing of the ground profile with the piling platform once it was in place. 

Limit State Geo

Our engineering team used specialist software for the geotechnical analysis of this design.

Limit State Geo was used to model the pile mat and the load bearing capacity. 

Below is the output for this piling mat showing the loads and modeled point of failure.

Piling Platform Verification Using Plate Bearing Tests

The piling platform was verified using a plate-bearing test. 

Kentledge was placed on top of a load cell and a hydraulic jack with the test plate of 610mm diameter underneath. The average settlement is measured to verify the stability of the piling mat under expected pressures.
