Short Course 1: Cone Penetration Testing (CPT/CPTU)
                              by Tom Lunne, Peter Robertson and John Powell

Purpose
The Cone Penetration Test (CPT) is fast becoming the primary in-situ test for soils.  This 1 day presentation will describe the test equipment, procedures and data collection and provide a guide to the interpretation of the CPT results for typical geotechnical applications.  The book entitled “CPT in Geotechnical Practice” will be the primary reference for the course and is included in the course fee along with a copy of the International Reference Test Procedure (IRTP) and draft CEN/ISO standard.

The presenters have between them over 75 years of experience of in situ testing of the ground much of it involved with the CPT/CPTU and are the co-authors of the core text "CPT in Geotechnical Practice".

Tom Lunne is presently Technical Advisor and Manager of Offshore Soil Investigations at NGI. He has been at NGI for about 35 years and has extensive experience from R&D and consulting projects involving planning, performance and interpretation of CPT/CPTU results. The projects have been in Norway but also in many other parts of the world. Main author of textbook on CPTU: Cone penetration testing in geotechnical practice; published in 1997.

Peter Robertson is the Technical Director of Gregg Drilling & Testing Inc., a major site investigation company located in California.  He has over 30 years experience as an educator, researcher, consultant and practitioner specializing is in the areas of in-situ testing of soils, earthquake design of geotechnical structures, soil liquefaction, pile design and soil structure interaction.  He has authored or co-authored 249 publications including the textbook on CPTU.

John Powell is head of Ground Properties at the Building Research Establishment (BRE) in the UK. He has spent much of his career working with both in situ and laboratory testing and their specification, interpretation and application of results to geotechnical design. He has of 30 years experience with the CPT/CPTU.  Co-author of textbook on CPTU.

"The book presents independent treatment of almost all aspects of cone penetration and piezocone testing: equipment and test procedures, test specifications, checklists for evaluation of data, interpretation methods and examples, empirical design approaches, and newer applications.  The avid reader will find in this definitive book comprehensive treatment of all of these, each with ample references to earlier work.

The authors have rendered a valuable service by sharing with the rest of the geotechnical community the vast knowledge and experience accumulated over many years of hard work.  We warmly recommend this book to students, their teachers, professors, practicing engineers and researchers."
