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

Synopsis of findings from breakout sessions (IWM 2003) 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

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

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

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

Regional Findings Western Europe 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

Regional Findings Nordic Countries 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

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

Regional Findings Nordic Countries 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 Instructor distributes micropile questionnaire to participants during this slide.

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.

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.

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?

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.

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

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

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

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

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.
