He was a Professor of Civil Engineering at the University of Ottawa from 1979 through 1996, and is an internationally recognized authority in the field of soil mechanics and foundation engineering, and, in particular, in deep FOUNDATIONS .

2 He has gained a wealth of practical experience during more than 40 years of work at home and overseas. He has written up his experience in 300 technical journal and conference papers, articles, books, and book chapters. SEMINAR OUTLINE: The COURSE comprises four main lectures leading up to and presenting the essentials of the Unified Method of deep FOUNDATIONS DESIGN for capacity, drag load, settlement, and downdrag for single piles, pile groups, and PILED FOUNDATIONS . The presentations are illustrated with several case histories of testing and DESIGN analysis including how to evaluate strain-gage measurements from instrumented pile loading tests and to assess residual load.

3 Settlement analysis is of vital importance to the DESIGN of PILED FOUNDATIONS , and the COURSE addresses principles of settlement analysis and how to calculate settlement of PILED FOUNDATIONS supported on single piles, and small and large pile groups. Pertinent aspects of Load and Resistance Factor DESIGN , LRFD, are discussed and some aspects of construction procedures are addressed. 08:15h Registration 09:00h Analysis of Load Transfer, Capacity, and Response to Load Load-movement response of FOUNDATIONS ; Methods of analysis of bearing capacity and load-transfer by beta, alpha, and lambda methods, and by CPT and CPTu methods; Set-up and relaxation; Residual load; Results of prediction events.

4 10:30h Break 10:45h The Static Loading Test: Performance, Analysis, and Instrumentation Methods of testing and basic interpretation of the results. How to analyze results from strain-gage instrumented piles to arrive at resistance distribution along the pile shaft and the pile toe response. Determining pile elastic modulus. The importance of residual load and how to include its effect in the analysis. Principles of the bi-directional test (the O-cell test) and how to analyze the results of an O-cell test. Case histories of analyses on results of static loading tests on driven and bored piles. LUNCH 13:30h Piles and Pile Groups Long-Term Behaviour and how we know what we know Important case histories presenting studies that demonstrated the actual long-term response of piles to load and observed settlement of piles and pile groups.

5 The lessons learnt will be referenced to aspects of DESIGN applying the Unified Method for DESIGN of PILED FOUNDATIONS considering capacity, drag force, settlement, and downdrag for single piles, pile groups, and PILED FOUNDATIONS . 15:15h Break 15:30 The Unified DESIGN Method. 1. Capacity (choice of factor of safety, and rules of LRFD and Limit States DESIGN ) and DESIGN for structural strength (including drag load) 2. Settlement of single piles and pile groups due to load directly on the piles and due to influence from adjacent activity (downdrag) 3. How to combine the various aspects for the DESIGN of an actual case with emphasis on foundation settlement illustrated with examples 16:45h Questions and Discussions Page 2 of 2 Vancouver Island Geotechnical Group A Local Section of the Canadian Geotechnical Society 2013 2014 Executive: Chair/CGS Section Director: J.
