There has been a significant change in the way pile foundations have been designed, installated and the various equipments that are available in the market. Until few years ago, a 1200mm diameter pile was considered a large diameter pile. However, in the last 2-3 years, pile diameters have substantially increased and thus it is now common to install 1200mm, 1500mm, 2m or even 3m diameter piles. Thus there is a need for the testing industry to keep pace with the current trends. Larger diameter piles need to be studied in more detail as not much past experience or codal requirements are available. The current presentation describes bi-directional load testing and high strain dynamic testing for large diameter piles. The presentation also describes static load test to 2600T which even today is not so common. Similarly, there has been a fundamental change the way SPT is computed on site in the last six months at few projects. The lecture also explains why SPT energy calibration is a requirement for the future and also that newer and more powerful rigs may result in fundamental changes in design. Advanced case studies in PIT or in CSL may also be discussed time permitting.
