Economic design of foundations: ICE MOGE 2nd ed. updates

Event organised by ICE

This event has now ended


Shallow foundations are often simple and easy to construct and offer a more economic and sustainable solution than deep foundations when site conditions are appropriate. Unfortunately, current design practice often leads to shallow foundations being considered inappropriate. The authors will debate their pros and cons, drawing on the recent edition of ICE Manual of Geotechnical Engineering to highlight potential opportunities and pitfalls. Some of the changes in the Foundation Design section of MOGE will also be illustrated:

  • Overview of risk management, getting the concept right early and approaches to achieve economic low carbon foundations.
  • New methods of shallow foundation design – bearing capacity under combined loading and settlement assessment.
  • The opportunity for economy with Piled Rafts.
  • Further guidance on driven pules. Benefits and some common risks.
  • Design of pile rock sockets.
  • Calculation of moment restraint in small pile groups.
  • A simple method for partially rigid large pile groups.
  • Global ground movements and their impact on piles.
