Spring to mind

Determining spring constants the accurate way

The structural engineer needed to design the raft foundations accounting for complex ground conditions, existing foundations and party walls. A simple estimate of subgrade reaction coefficient just would not do for the Barts Square development in cental London.

Advanced 3D FEA modelling took proper account of all these to provide accurate spring stiffness values.


  • 3D FEA of the ground, existing foundations, proposed foundations and adjacent building sub-structures.

  • Simulation of demolition, reconstruction and permanent loading.

  • Prediction of raft bending moment to aid its strutural design.

  • Output of coefficients of subgrade reaction for structural analysis model.

  • Prediction of adjacent foundation and party wall settlements, damage categories.
