1. Synopsis of Findings from IWM 2003, Current and Future Status of IWM, and Breakout Session GuidesDr. Donald A. Bruce

2. Overview • Synopsis of findings from breakout sessions (IWM 2003) • Future of IWM (based on respondents comments after IWM 2003) • Breakout Session Guide for IWM 2004

3. Synopsis of Findings from Breakout Sessions at IWM 2003 • State of International Knowledge Practice and Knowledge • Research and Development, and Future Needs Assessment • Education and Knowledge Dissemination

4. Synopsis of Findings from Breakout Sessions at IWM 2003: State of International Knowledge • Global Findings • Case 2 projects not conducted due to lack of design tools • Debate on definition of micropile (Finland and U.K.) • Obstacles to micropile industry growth • Education of Owners • Lack of codes (U.S.A.) • Lack of capability to predict movement • Inertia in market, resistance to new technologies • Fast track projects do not allow time for micropile design • Trends toward lower W. European participation in IWM and imbalance towards N. American contractors

5. Synopsis of Findings from Breakout Sessions at IWM 2003: State of International Knowledge • Regional Findings • North America • No use of inclined piles • Pile/cap connection knowledge lacking • Codes are old/poor • Growing use in karst • Education of Bridge/Structural Engineers needed • New research on drill casings • “Secrecy” problems with database compilation • Concern over suitability of multi-component grouts

6. Synopsis of Findings from Breakout Sessions at IWM 2003: State of International Knowledge • Regional Findings • Western Europe • Market generally flat • Market is equally private and public • Widespread use of Titan • Good codes • Potential for railroad embankment stabilization • Some use of grout for drill flush

7. 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. 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

9. 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

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

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

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

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

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

15. 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.
