Highlights of IWM Venice Opening oration in Latin. Keynote by Professor Fedele Lizzi. Overview of past IWMs Presentations: - Richmond-San Rafael Bridge - In Situ Reinforcement for Slopes - Probability Studies, Horizontal Loading Tests - Buckling of Micropiles Review of various international codes and guidelines (France, Eurocode, Japanese, DFI, FHWA, U.K.). Review of research programs internationally. Note items 1, 2 and 3 exist because micropiling is a newly developing and innovative technology.

Lessons of IWM Venice Too many presentations – not enough time for discussion and review. Breakout session could have been better moderated and analyzed. IWM was then “too young” to consider coordinating a full conference. However IWM, with ADSC, was clearly a very active and productive group of friends, retaining the potential to be an extremely positive influence on engineering practice internationally. These two definitions can also be described as “Prescriptive Specifications” and “Performance Specifications”, respectively.
