Meeting Notice

The main structure of the World Trade Center consisted of an external steel tube with closely spaced col-umns, internal gravity columns and simply supported steel truss joists connecting the interior gravity col-umns to the columns of the exterior tube. In the aftermath of the col-lapse of the WTC towers, in 2001, the speaker conducted a fi eld investiga-tion of the structural remains and in 2002 he testifi ed before the Com-mittee on Science of the U.S. House of Representatives. Since then, he has conducted nonlinear dynamic analyses of impact of airplanes on tall buildings including the col-lapsed WTC towers. One of the main objectives of these studies was to fi nd out what would have happened if the structure of the WTC towers were a traditional system, instead of the innovative system that was used.

and provide SEAONC with a voice in the rule making deliberations of the agencies that protect the public’s safety in the design and construction of transportation structures. We hope that this new committee will serve in much the same way that SEAONC Seismology and Existing Buildings committees have worked to develop and articulate a consensus-derived understanding of the fundamental is-sues in designing, evaluating and/or rehabilitating buildings.

Next year’s committee will be co-chaired by Mark Ketchum. Initially, his objectives will be to develop a working committee core that will identify a program of future goals. It is our hope that by this time next year, there will be a new and impor-tant forum within SEAONC for the advancement of our profession.

I would like to thank Board member and Treasurer Mike Fretz and the other SEAONC members who have worked with him to help launch this

Based on the 2001 CBC & the 2003 IBC Following 5 successful years of presentations, BYA Publications is pleased to announce the 2006 SE Review Workshops. The program is comprised of a detailed interactive review of a comprehensive selection of problems included in the California Structural Engineer exams and discussion of more recent developments in structural and seismic engineering. With the adoption of the IBC in California in near future, the workshops also provides a great introduction to these new provisions, which also include the ASCE-7-02, 2002 ACI-318, 2002 AISC Seismic and 2002 MSJC.

All classes are on Saturdays or Sundays from 9:00 a.m. to 4:00 p.m.** At the Hayward La Quinta, 20777 Hesperian Blvd, Hayward, CA 94541 (510) 732-6300

What Last Year’s Participants Are Saying About Our Workshops?

I did take both the national and state-specific SE examinations and passed them on the first try. Though it was an effort to make it all the way through your preparation course (I live around 3-1/2 to 4 hours away and didn’t miss a single session), I believe that it significantly contributed to my success. The SE Review Manual and the host of celebrity (at least within the SE community) guest speakers you had lined up for us helped to sharpen the areas I was weak in. I wouldn’t have attempted the exam without first taking your course. Thanks for the valuable service you provide to the structural engineering profession in this state. Steve Mickelson, SE, LEED AP, NorthStar Engineering

I passed both tests! Thank you for organizing the workshop. It was a great experience for me and it helped me greatly in my preparation. I have already recommended your class to a few of my friends, so hopefully you will need a bigger room next year.

Mahmoud M. Hachem, Ph.D, SE, Senior Associate, Wiss, Janney, Elstner First of all, I would like to thank you Ben for putting this review course together. It helped tremendously and got me focused on studying early enough that I felt very prepared entering the first day of the exam. I believe it was a large part of the reason I passed. Thanks again and I will be recommending the course to all of m friends/coworkers. Brad Erickson, S.E., Associate, Watry Design

Indonesia Tsunami Housing Reconstruction

By Tim Hart, S.E.

Beginning in the Spring of 2005, a group of SEAONC engineers came together to donate their time and engineering expertise to assist in the reconstruction efforts in Banda Aceh, Indonesia, the region hardest hit by the December 26, 2004 earthquake and tsunami. The group has been working with Build Change, an international 501(c)3 non-profit organiza-tion based in San Francisco. Founded by Dr. Elizabeth Hausler, recently named a “Person of the Week” by ABC News, Build Change’s philosophy is to build “earthquake-resistant houses in devel-oping countries and change construc-tion practice, so that homeowners and builders continue to build earthquake-resistant houses after Build Change’s intervention is finished.” Another unique aspect of Build Change’s approach is to not only mobilize local engineering and construction expertise in the affected region but also utilize the earthquake engineering expertise of structural engi-neers here in Northern California.

The initial work done by the volunteers consisted of evaluating 4 home designs common to the region and identify the elements that would be most likely to sustain damage and pose a life safety hazard in an earthquake. Once the criti-cal building elements were identified, the team developed design and construc-tion modifications that would be low in cost and be more earthquake resistant. During this process the team of engi-neers had to take into account several factors that they did not normally deal with in their standard practice, including but not limited to: the unavailability of reinforced masonry blocks, the scarcity of deformed rebar, the lack of available material testing laboratories, the exper-tise of local builders, the preference for confined masonry construction that is not used in California, and a construc-tion budget of around $3,000 per house.

The group was able to overcome these limitations and develop modified designs for each building, which were then forwarded to Build Change’s local design team in Banda Aceh.

The home designs were reviewed by the homeowners involved in the pilot project set up by Build Change with Mercy Corps. The homeowners selected the confined masonry house, after which Build Change’s design team prepared the final set of construction documents. Before construction began, the volunteer team reviewed the final construction documents and provided additional com-ments and suggestions for improvement. The volunteers have remained involved now that construction has started by reviewing the construction and helping to develop a construction and inspection checklist to aid both the contractors and the homeowners.

As of this writing 15 homes are under construction with plans for at least 50 more homes in the works. In addition, several other relief agencies in Banda Aceh have seen the Build Change homes and been so impressed by the quality of the design and construction that they have asked for Build Change to review other home and building designs being used in the reconstruction of Banda Aceh.

The group of Bay Area volunteers consists of: Kevin Moore and Evan Reis from Cer-tus Consulting (who served as the project managers); Lisa Cassedy, Forrest Lan-ning, Tim Hart, David Kirschenbaum, Jay Pisano, Rafael Sabelli, and Carl Wilford from DASSE Design; Margarite Bello from Bello & Associates; Matt Eatherton from GFDS Engineers; Jeff Falero; Andrew Mole from Arup; and Andy Fennell and Tom Voss from Scientific Construction Labs.

May Business Forum Luncheon

MEETING TOPIC:BUILDING YOUR FIRM’S VALUE

DATE & TIME:Wednesday May 24, 2006

12:00 pm - 1:30 pm Lunch/Program

LOCATION: City Club – San Francisco

155 Sassome St. San Francisco

Whether you are implementing an internal transition program or planning on selling your firm in the future, the same critical points will determine the value of your prac-tice. There are key points that you should consider now that will enhance the value of your firm and the more time you have to develop and implement important strategies, the more you will receive when it is time to pass on your legacy to the next generation or sell to a third party.

The speaker for our May business forum will be Mr. Steve Quiggle of Management Design, a business consulting firm to design industry, who will lead a discussion on what potential buyers look at when assessing your practice. In this interactive meeting, Steve will give details on what needs to be considered when building a practice for value, and he will explain the basic valuation formulas used for internal transi-tions and external sales and how various factors affect them.

Mr. Quiggle has over 30 years of experience directing the corporate finance, accounting, administrative and MIS func-tions of major A/E and land planning practices. He pos-sesses a comprehensive understanding of the importance of long-range and strategic planning, operations, mergers and acquisition, incentive compensation and ownership transi-tion in the management of an efficient and profitable prac-tice.

Steve also offers expertise in the coordination of global man-agement operations and organizational structures, particu-larly for multi-discipline firms with branch offices, including those located in foreign countries. Most recently, Steve was the Vice President for Strategic Planning and Finance, and Managing Principal of the Corporate Group for EDAW, Inc., a global practice that provides landscape architectural, land and urban planning, environmental and economic planning services. During Steve’s tenure, EDAW grew from 110 em-ployees to over 800 with 23 offices, and expanded its branch office network to Europe, Asia and Australia.

CASE and ACEC: Who are they and why are they coming to San Francisco?

By Ed Bajer, JD

CASE is the Council of American Structural Engineers. It is a national organization and part of the American Council of Engineering Companies (ACEC) which has over 5000 member firms of which about 2500 offer structural engineering services. Over 600 of them are in California. Both CASE and ACEC have firm-based memberships not individual and what distinguishes them from other structural organizations is that they concen-trate exclusively on the business, management and profitability aspects of engineering. Their headquarters are in Washington, DC where they maintain among other things a substantial government affairs and lobbying staff. Their websites are www.acec.org and www.acec.org/case.

CASE has a variety of products among which are contracts covering various contracting situations especially drafted for structural firms, a proposal preparation spreadsheet that lets you “play” with the numbers, several “Guidelines” including “Coordination and Completeness of Structural Construction Documents” and a Risk Management Program just for struc-tural firms. SEAOC has agreed to join with CASE in putting on a day and a half Convocation in San Francisco on October 19-20, 2006 that will focus on managing risk on a structural project. It will include sessions on negotiating with the owner, managing condo projects and deal makers and breakers. A special presen-tation will be made by the structural engineer who oversaw the reconstruction of the Pentagon after 9/11. Watch this space for more information.
