Developments in site investigation practice during the past decade are reviewed in relation to exploration techniques in soft ground. Some of the problems that commonly occur in attempting to obtain quality samples are discussed and a number of refinements to traditional boring and sampling methods that are aimed at improving matters are described. However, research and development effort has been, and continues to be, centred on the promotion of in-situ test methods as a means of improving soil profiling and to facilitate the rapid determination of soil parameters. In-situ techniques, which are now in widespread use, are described and the course of their further development is suggested. Greater use of the principles of quality assurance, together with training and accreditation of operators, will give greater confidence that specified quality levels are being attained and should lead to increased efficiency.
