4. 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.

5. 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.

Responsibility is divided between the owner and the contractor depending on:
The designer’s experience with micropile installations
Owner’s confidence with the micropile contractors
The critical nature of the application
Note:
In Seattle, responsibility for organizing sessions given to Chairs and Coordinators.
Seattle IWM designed to be more interactive and proactive.
Active participation needed.
