Synopsis of Findings from Breakout Sessions at IWM 2003: State of International Knowledge
Regional Findings
Nordic Countries
Market divided between driven piles and drilled/grouted types (including Titan)
Strong and growing private sector
Market otherwise steady (residential)
Strong codes
Material suppliers leading market

8. Regional Findings Japan
Synopsis of Findings from Breakout Sessions at IWM 2003: State of International Knowledge
Regional Findings
Japan
Using inclined piles (up to 200 tons)
Concept of repairing pile caps after seismic events
Public market increasingly strongly
No Titans yet
Japanese “manuals” very strong
Need high energy to “sell” micropiles

Material suppliers leading market
Instructor distributes micropile questionnaire to participants during this slide.

10. Synopsis of Findings from Breakout Sessions at IWM 2003: Research and Development, and Future Needs Assessment
Global Findings
Owners need better guidance on construction and design
Potential for PDA
General admiration for new Finnish and Japanese research projects
Eurocode gives guidance on design
Positive ADSC research initiatives
No report of U.S. States Pooled Fund Study
IWM database/website would be helpful
Review the team exercise with the participants and ask if there are any questions relating to the exercise requirements.
State that different portions of the exercise should be completed (or at least discussed) by the teams as the lessons apply throughout the 1½ days of the workshop and that the final product will be developed and presented by the teams at the end of the workshop during Lesson 12.

11. Synopsis of Findings from Breakout Sessions at IWM 2003: Research and Development, and Future Needs Assessment
Research Needs
Strain compatibility with ground and foundation for seismic and lateral loading conditions
Pile/cap connection
Casing joint capacity in bending
Inclined piles in groups
Case 2 concepts
LRFD version of micropile design manual
Update FHWA unpublished Volume 5
In advance of the workshop, this list will be sent to the Host State to guide the structure of their presentation. Handouts are encouraged. Time should be strictly limited (10 to 20 minutes) to ensure that this first lesson does not overrun.

12. Synopsis of Findings from Breakout Sessions at IWM 2003: Education and Knowledge Dissemination
Global Findings
IWM maintained as “Center of Excellence”
Lack of permanent administrative leader noted
Function of IWM: strategic and/or technical?
“Good traits” of IWM
Informality of data exchange
Camaraderie
Communication
Education
Planning
Teaching
Were the learning objectives of Lesson 1 met?

13. Synopsis of Findings from Breakout Sessions at IWM 2003: Education and Knowledge Dissemination
IWM needs to
Allow more time for in-depth technical knowledge exchange
Produce something useful
Find a funding source
Act as publications clearinghouse
Provide input to codes
Issue practice updates
Develop a website
Develop university-level textbook
Develop literature database
Organize training events to raise funds
Talk about failures
Bring up only the heading of the slide first. Before making the list of advantages appear on the slide, solicit participant interaction by asking what they think the advantages may be and list the responses on a flip chart. Compare the responses to the advantages listed on this and the following slide.
Instructor should mention other types of piling (e.g., continuous flight augers) or ground treatment (e.g., jet grouting) as alternative solutions. Micropiles are not the best solution for every job.

14. Synopsis of Findings from Breakout Sessions at IWM 2003: Education and Knowledge Dissemination
IWM needs to stop
Considering a conference
Having political undertones (secrecy, posturing)
Commercial marketing
Considering influencing codes
Considering annual practice updates
Point out for the tower structure that by installing the reticulated micropile system, the structure becomes integrated with the underlying soil mass, the resulting center of gravity is lowered and therefore greater stability for the structure is achieved

15. An executive officer needs to be appointed Funds need to be raised
Future of IWM
Unanimous conclusion from IWM 2003 that IWM should establish Secretariat
An executive officer needs to be appointed
Funds need to be raised
Resulting organization must adhere to IWM core values

16. IWM Current Status Critical time for IWM due to lack of FHWA funding
One year of replacement funding provided to IWM by ADSC (Industry Advancement Fund – through contributions from Micropile Committee)
Amendment to ADSC focus currently proposed to include micropiles (votes due back 31 August)
Potential for IWM inclusion within ADSC, but may not be attractive

17. Functions of Secretariat must be defined
Breakout Session B addresses IWM future needs (funding, secretariat functions, website)
Need focused discussions on “products” (database, website, texts, etc.) suitable for external funding sources

18. IWM 2004 Breakout Sessions
The goals of the breakout sessions are:
To allow specific, recurring “hot” topics to be addressed in detail, and
To allow defined work products (strategies, plans, outlines, etc.) to be developed for specific issues.
