CTBUH 2011 Annual Leaders Meeting

October 2011

Fifty CTBUH leaders from the Advisory Group met at the seminal Dongbu Financial Center tower in Seoul, Korea on Sunday, 9 October 2011, for the 2011 Annual CTBUH Leaders Meeting. Taking place in conjunction with the CTBUH 2011 World Conference Korea, meeting attendees included CTBUH Trustees, Advisory Group members, Country Representatives, Working Group/Committee Chairs & CTBUH Staff.

CTBUH Chairman, Prof. Sang Dae Kim, opened the meeting welcoming all in attendance and introducing two new Trustees, Dennis Poon and Steve Watts. A special note of thanks was given to retiring Trustees, David Scott and Charles Killebrew, who will continue to serve as Advisory Group members for the CTBUH. Prof. Kim introduced new CTBUH Chairman-Elect, Timothy Johnson, who presented leaders with his Chairman’s Two-Year Plan. Following, CTBUH Executive Director Antony Wood, presented the leadership with an overview of the Council’s latest membership reports, current CTBUH operations, as well as recent and on-going initiatives.

CTBUH Chair-elect, Timothy Johnson, presents to CTBUH leaders. Dongbu Financial Center.

After the main assembly, the leaders separated in to the following small group meetings: Height Committee, International Representations, Outriggers Working Group, Research Academic and Post-Graduate Working Group, Seismic Working Group, and Wind Engineering Working Group. At noon, break-out meetings took a recess for lunch, provided by the Seoul Conference Organizing Committee. After lunch, leaders continued their separate meeting discussions.

CTBUH Combined Leadership Forum
The final portion of the 2011 Annual Leadership Meeting provided the opportunity for group chairs to give reports and answer questions to all leaders. Each group reported as follows:

Height Committee: Review of Height Criteria
Committee Chair, Peter Weismantle, reported on his group’s decision to revise the name of the CTBUH Height Committee to “CTBUH Height & Data Committee” moving forward. The committee discussed new improvements to the Tall Building Database (ie. additional and more accurate data being obtained through the use of  data forms; new features added; and other enhancements to soon be launched) and suggested considerations (ie. an expanded credits list to include “other consultants” and “materials suppliers /manufacturers”, which could be linked as a membership benefit; improving web search hit rate by adding “Google Tags” to rank the database closer to the top of search lists, and where the database fits into the CTBUH vision, and how it can be a greater benefit to members).

The Height Committee evaluates its policies and its identity. Country Leaders discuss new chapter guidelines.

International Representation: Establishing a Charter for Chapters
CTBUH UK Country Representative and new Board of Trustee member, Steve Watts, presented his report from the Country Leaders meeting. In considering the mode of operation of current CTBUH global chapters, there are a number of CTBUH chapters enjoying some success (ie. the Australian CTBUH and Korean CTBUH). Though some global chapters operate as completely independent entities, perhaps the key to the successful creation of a new chapter – and the development of existing ones – is an appropriate financial model, with a clear and legal interface with the CTBUH headquarters.

With this in the mind, the group considered three possible chapter models: wholly funded by CTBUH; fully income-generating locally; and local events sponsored by independent businesses (as is the case of CTBUH Qatar, where an effective local chapter hosts quarterly seminars with invited speakers, funded by local companies who directly pay for the facilities/equipment/refreshments).

Some form of shared cost/income may be right in some places, but the best approach will be contingent upon the respective legalities, taxation, culture and other issues evident in different geographies. While CTBUH brand consistency is certainly necessary, any established chapter framework must allow flexibility to deal with these variances. A draft template will be soon prepared covering the guidelines, expectations, CTBUH support and the initial geographical focus.

Outriggers: Final Stages of Working Guide
Representatives from Arup, Skidmore Owings & Merrill LLP, and Thornton Tomasetti met together to discuss the progress and latest draft of the new CTBUH Outriggers Working Group report. Group Co-Chair, Hi Sun Choi, reported on the meeting. The group reviewed the most recent content of the report and discussed selection of an appropriate publication title. Ms. Choi stated that the first draft of the document is scheduled to be completed and available by the 2012 Shanghai Congress.

The newly formed Outriggers Working Group strategizes for the year. The Research Working Group discusses new research opportunities.

Research: Making Funding and Research Happen
As co-Chair of CTBUH’s largest working group, Philip Oldfield reported on the day’s meeting. Topics reviewed by the working group included exploring seed grant research funding and soliciting a peer review committee for grant proposals. In addition, the group generally decided to more efficiently allocate tasks to subgroups and ultimately reduce the number of subgroups by one and reallocate the responsibilities of the dissolved areas to other subgroups.  It also committed to have the Roadmap on the Future of Tall Buildings (Roadmap) completed before the 2012 Shanghai Conference and to present it at that gathering. A joint project with Conseil International du Bâtiment (CIB) and United Nations Educational, Scientific and Cultural Organization (UNESCO), the Roadmap will identify potential research gaps in the tall building industry to drive new research proposals and the activities of the Research Academic and Post-Graduate Working Group sub-committees.

Seismic: Future Plans after the 2008 Published Report
Working Group co-Chair and past CTBUH Chairman, Ron Klemencic, reported on the review of the CTBUH Seismic Guidelines publication. Since the guideline’s release, the group identified potential issues to address in an updated version of the guideline. The working group is proposing to organize a special track of speakers or workshop adjacent to the 2012 Shanghai Congress, featuring practitioners from around the world, with the intent to publish a summary paper that draws state-of-the-art information together. The working group also discussed translation of an updated Seismic Design Guidelines into Chinese.

Leaders of the Seismic Design Working Group make plans to update their publication. The Wind Engineering Working Group outlines its upcoming technical guide.

Wind Engineering: Final Review of Wind Tunnel Testing Guidelines
As co-Chair of the Wind Engineering Working Group, Board of Trustees member, Peter Irwin, presented the progress of the new Wind Engineering Guidelines, a CTBUH technical guide for wind tunnel testing to promote global best practices in wind engineering. One main purpose of the guideline is to propose standard formats for presenting results of wind tunnel testing for better comparison and understanding of findings. The group plans to finish the first draft of the new working group guideline by the end of 2011 and forward it to review committee, in hopes to have the new guideline available by the Shanghai Congress.

In other business, past CTBUH Chair, David Scott, reported on the CTBUH research project currently underway in collaboration with the Korea Institute of Construction Technology (KICT).

With 42 years of multidisciplinary collaboration, the Council on Tall Buildings and Urban Habitat’s mission of disseminating best-practice knowledge to the tall building industry is as relevant as ever. The momentum of CTBUH leadership and their drive to expand the reach of the tall building network further into academia and into global industry will certainly serve to enrich the future of the urban environment.
