These two volumes form the proceedings of the Second BGA International Conference on Foundations, organised by the Geotechnical Engineering Research Group of the University of Dundee in June 2008. Over 150 papers from 40 countries are included, grouped into 14 themes, which provide an international perspective of the latest advances in foundation engineering in research, design and practice. The topics covered in Volume One are piles, excavations, and offshore foundations, and Volume Two focuses on ground behaviour and improvement, shallow foundations and slopes. Keynote papers by eminent geotechnical engineers are included: The relevance of developer costs in geotechnical risk management - Tim Chapman. Offshore foundation design - a moving target - Mark Randolph and Dave White. Piles under horizontal load: an overview - Gianpiero Russo and Carlo Viggiani.
