SEAONC/SEAOSC Hosts The Third Annual Buildings At Risk Summit

October 1st Dinner Meeting: SFMTA Central Subway Project (T-Line): Union Square/Market Street and Chinatown Stations

Speakers: Marco Scanu, SE, Principal, Forell/Elsesser EngineersDavid Abrahams, PE, Senior Engineer, Parsons BrinckerhoffAlbert Hoe, Deputy Program Manager, Central Subway Project

The Central Subway Project will construct a new 1.7-mile extension of Muni’s T-Line light rail. The Central Subway Project is Phase 2 of the Third Street Light Rail Project and will extend the existing Phase 1 initial operating segment from its current connection to the Embarcadero Line at Fourth and King Streets, to Chinatown. The $1.6 billion project is now underway with the launch of the first of two tunnel boring machines earlier this year that will eventually make their way to North Beach. Construction of the subway tunnel and stations will con-tinue through 2017 and the subway is slated to open to the public in 2019.

Colleagues,

For this month’s President’s Message, I want to take the opportunity to update our local Northern California mem-bers with a few statewide (SEAOC) ac-tivities that have an effect on all of us. I also want to strongly encourage all of our members to attend the upcoming Buildings at Risk Summit scheduled for October 15th here in San Francisco. SEAOC Update

As many of you are aware, The SEAONC president, vice president and past president act as delegates to SEAOC and attend regular meetings with all SEAOC delegates from other member organizations. It is our re-sponsibility to update these members on SEAONC’s ongoing tasks and ac-complishments and conversely to up-date our own Board and members on significant statewide activities. For this issue, I want to briefly summa-rize a few items from our last meeting, which occurred at the annual SEAOC Convention in San Diego. Additional information is available within SEAOC Talk and on the SEAOC website.

2012 Seismic Design Manuals and WebinarsSeismic Design Manuals are now avail-able on the SEAOC website for pre-order at http://www.seaoc.org/book-store. Some volumes are further along than others but all should be available within the next month or so. Five

October 1st Meeting (Cont. from Page 1)

The extension will include 4 new stations, 3 of which will be underground: Chinatown Station, Union Square/Mar-ket Street Station, and Moscone/Yerba Buena Station. This presentation will focus on the design of the Chinatown and Union Square/Market Street Stations and in particular on the unique design challenges presented by the two highly congested urban sites. The stations’ construction will in-clude a variety of ground support construction techniques including slurry wall, large diameter battered drilled shafts, and the Sequential Excavation Method for mined portions. Construction access, maintenance of heavy pedestrian and vehicular traffic, soil settlement mitigation and adjacent his-toric structures all posed additional significant challenges for the design of the two stations.

The Summit will provide insight for diverse stakeholders:

• Building owners & managers • Public officials & policy-makers • Homeowners & business owners• Emergency managers & first responders • Real estate & insurance professionals • Anyone interested in community resilience

Sponsorship opportunities are available NOW! Join Simpson Strong-Tie Company, Inc., MiTek, and ICC Evaluation Services.

October 22nd South Bay Dinner Meeting The next Big Thing…….Cross Laminated Timber!

Not just plywood on steroids but instant multi-story struc-tures without formwork, pouring and waiting to cure. The CLT system is a multi-layer wood panel where each layer of boards is placed cross-wise to adjacent layers for rigidity and stability. Once CNC framed you have the perfect cus-tom kit for a quick and easy fit. But how does the system ac-commodate mechanical electrical and plumbing? What are the connections for vertical and lateral loading? Is it code ready? We will talk about all of it.

Speaker Bio – Kris Spickler P.E.

Kris Spickler is the Heavy Timber Specialist for Structur-lam Products Ltd. in Penticton, British Columbia, Canada. He holds a Bachelor of Science degree in Civil Engineering, with emphasis on wood structural design, from Fresno State University, California.

SEAOC webinars are scheduled starting October 17th with Volume 1 and ending January 16th with Volume 5 and will provide a very good overview of the new volumes. SEAOC is also exploring additional opportunities with NCSEA and S.K. Ghosh Associates for jointly sponsored webinars.

SEAOC WebsiteSEAOC officially launched its new website on September 18th and just in time for the 2013 Convention. Similar to SEAONC’s recently launched website, new content is contin-ually being added and migrated over from the old site. I’m sure they would appreciate any feedback on the content or usability. Emails can be sent to Don Schinske dschinske@seaoc.org.

Professional Practice ActSEAOC is continuing to work on supporting legislation which would modify California’s current Professional Prac-tice Act to include a definition of significant structures. The proposed language would require that these buildings be designed and sealed by California licensed structural engi-neers. The proposed definition of what constitutes a signifi-cant structure is still being discussed but it could be linked to Building Risk Categories as defined in CBC table 1604.5. SEAOC has introduced the proposed language to ASCE (region 9) and AIA-CC and it has been met with neutral to positive support.

Reports from Technical CommitteesAs part of the October SEAOC Board meeting, all techni-cal committees are requested to report on their past accom-plishments and proposed activities for the coming year. These are generally activities that occur at the state commit-tee level but may also parallel work being done within our own and other regional sections. Rather than summarize any information here, these documents have been posted to our new SEAONC website. It is truly exciting and to see the relevant work being produced by our statewide mem-bers and I would encourage everyone to review these docu-ments. http://seaonc.org/seaonc-news

Buildings at Risk Summit As mentioned last month, I want to strongly encourage all of our members to attend the inaugural “Buildings at Risk” Summit which will be held on October 15, 2013 in San Fran-cisco. It is imperative that our organization make a good showing here and I definitely believe that this is an ideal opportunity for SEAONC to gain very important visibil-ity within a wide and diverse group of stakeholders while promoting perhaps our single most important goal - public safety and community resilience. Please register today if you have not already done so and please spread the word on this first ever Northern California event to ensure suc-cess!

SEAONC Fall Seminar November 6th & November 13thSEAONC 2013 Fall Seminar: Retrofit of Soft Story Wood Framed Buildings

Soft story wood framed buildings are among the most sus-ceptible building types to damage from earthquakes. Surveys conducted in several Bay Area cities, including San Francisco, Oakland, San Jose, and Sebastopol, have identified over 18,000 soft story wood frame buildings in their cities, most of which are residential buildings. New research has led to the devel-opment of improved procedures for evaluating and retrofit-ting these structures. In addition, municipalities throughout the Bay Area have begun to adopt policies and ordinances to mitigate these buildings with the goal of increasing the resil-iency of our communities.

As a service to engineers, architects, and builders in the Bay Area, the SEAONC Continuing Education Committee is proud to present the 2013 Fall Seminar on the retrofit of soft story wood frame buildings. Our speakers will present the latest research and guidelines for the seismic evaluation of soft story wood framed buildings, including case studies. The seminar will conclude with the speakers who will discuss the new San Francisco program for the mandatory retrofit of soft story wood framed buildings.

Summary of Soft Story Group ActivitiesBy Jim Malley

The SEAONC Soft Story Ad Hoc group has been very active during the last year. Our primary activity has been to sup-port the development of San Francisco Building Code Chap-ter 34B (created by Ordinance 66-13, signed April 18, 2013) and the supporting Administrative Bulletin (to become AB 107) that provides the technical interpretations and direc-tion that will be used by the San Francisco Department of Building Inspection in their enforcement of the chap-ter. This work is being done in conjunction with the City’s Earthquake Safety Implementation Program (ESIP), led by Patrick Otellini.

The technical discussions of the Ad Hoc Group have been held in conjunction with the SEAONC Existing Buildings Committee. A major emphasis of these discussions centered on the application of FEMA P-807 Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings With Weak First Stories, since along with ASCE 31, ASCE 41, and IEBC Appendix A4, this new document is adopted by Chapter 34B as criteria for soft story retrofits. The group provided detailed input and recommendations on how to apply and/or modify FEMA P-807 for use in AB 107, with a major em-phasis on drawing some consistency between the results of the various approaches.

The group also worked closely with SEAONC Special Proj-ects Initiative Awardee Jonathan Buckalew who did a series of comparative soft story retrofit designs using the various alternate design methodologies. The discussion of these de-signs was instrumental in developing our input to AB 107. Finally, the group worked with the Continuing Education committee to develop the 2013 SEAONC Fall Seminar “Seis-mic Risk Reduction for Soft-Story Woodframe Buildings: Test Results and Retrofit Recommendations from the NEES-Soft Project”, to be held on November 6th and 13th at the PG&E Auditorium. Participants from the SEAONC Soft Sto-ry Ad Hoc and Existing Buildings Committees will speak on key issues related to implementing the various design standards as well the recent NEES-Soft testing program.

I would like to recognize and thank the SEAONC members that participated on the Soft Story Ad Hoc Committee for the large amount of time that they have committed to the effort. They include: Laurence Kornfield (liaison to ESIP), David Bonowitz (consultant to ESIP), Ron Hamburger, Steve Harris, Dave McCormick, Gary Mochizuki, David Mar, Brian McDonald, Randy Collins, Mike Gemmill, Bruce Mai-son, Chris Poland, Marguerite Bello, Mark Moore, Jonathan Buckalew, Marko Schotanus and Jenni Tipler.

October Mini Seminar - Practical Non-Linear Analysis for the Design OfficeDescription: Non-linear analysis (both static and dynamic) has become increasingly popular over the last decade. With the increased use of Performance Based Design, engineers are routinely using non-linear analysis in some form or fea-ture to justify their design. This seminar will be presented in a case history format where the presenter will illustrate how non-linear was used to the engineer’s advantage in past projects. Specific modeling issues such a rocking, pound-ing, foundation modeling etc. will be tackled and useful analysis and design tips will be provided.

Speaker Bio: Anindya Dutta has over 14 years of experience in structural and earthquake engineering. He has provided analysis and design of a variety structures in high seismic zones. Dr. Dutta’s experience also includes seismic evalu-ation and strengthening of low to high rise structures. He has taught graduate and undergraduate level courses on concrete design and structural analysis at the State Univer-sity of New York at Buffalo and currently serves as a lec-turer at San Francisco State University. He has authored a number of technical reports and journal papers as well as served as a member of the review board for ASCE’s Struc-tural Engineering Journal.

Guildlines For Reviewing Concrete Mix DesignsIn accordance with the 2010 CBC

The SEAONC Construction Quality Assurance Committee has developed a guideline for reviewing concrete mix de-signs. The purpose of this document is to serve as a resource to the structural engineering community in the review of concrete mix design submittals.

Concrete mix designs are submitted for review so that the reviewer can verify the contractor is interpreting the con-struction documents correctly. These guidelines were de-veloped to assist the engineer reviewing concrete mix de-signs. While the main body of the guidelines focus on the process of reviewing the mix design the appendices provide a discussion of performance issues and code requirements that should be considered as well as a discussion of what typically will be considered when writing the project speci-fications and how the specifications are typically organized.

A Pioneer of Offshore Oil & Gas Structures William “Bill” Matthew Martinovich, S.E. 1930 – 2013By Reinhard Ludke, S.E

This article is about Bill Martinovich and it is a story about the evolu-tion of engineer-ing ocean struc-tures. Oil and gas reserves were dis-covered offshore and Bill’s structural engineering career parallels the evolu-tion and develop-ment of the offshore oil and gas exploration and production industry. Bill was a pioneer and a technical leader in the science and engineering of floating exploration vessels and fixed production platform structures. Bill joined SEAONC in 1961, was elevated to Life Member. He continued to at-tend the annual June SEAONC business meeting.

Bill died on June 5, 2013. He was born in San Francisco in 1930, attended Balboa High School, and received his Mas-ters of Science in Structural Engineering and Structural Me-chanics from the University of California at Berkeley. Bill swam for the Balboa High School swim team and was a life-guard at Fleischhacker Pool, a very large, salt water, swim-ming pool that was located near the Pacific Ocean in San Francisco. While studying engineering at Cal, he played water polo on the Cal team. In the 50’s he was among the early pioneers of surfing the big, cold, waves at San Francis-co Ocean Beach. He continued hunting those waves along the California coast throughout his life. He was a lifelong fitness swimmer and was involved in his weekly swim rou-tine the day he passed away.

Bill received his Bachelor of Science degree and was elect-ed to the Tau Beta Pi Engineering Honors Society in 1952. After graduating from Cal, he went to Southern California to work in the aircraft manufacturing industry. This was closer to warmer ocean water and waves for his surfing pas-sion. He served as a Lieutenant in the Navy and after his military service he returned to UC Berkeley for his Master of Engineering studies in structural engineering. After graduation, he joined Earl & Wright Consulting Engineers in San Francisco as a staff engineer. He ultimately rose to be the President of the firm. His early career at Earl & Wright involved engineering construction rigging, shoring, equip-ment and temporary methods for large construction com-panies that were building the major bridges in San Fran-cisco Bay and throughout the country. His career at Earl & Wright rode the wave of increasingly challenging and complex engineering, research and development of floating offshore oil and gas field exploration and oil production ves-sels and structures.

Standard Oil of California, now Chevron Oil Company, used Earl & Wright to furnish the engineering for the struc-ture, fabrication, and installation of Platform Hazel, off the coast of Carpenteria, California in 1959. This tubular steel structure was towed floating horizontal and tilted up us-ing sequential ballasting of watertight compartments in the structure. Signal Oil & Gas ordered Platforms Hope, Hei-di, and Emmy for producing oil off the cost of Huntington Beach. The ocean water depth at these sites was under 100 feet.

The near shore exploration for oil and gas used buoyant platforms, with broad bases that were towed over the po-tential reserve, and ballasted with seawater to rest on the bottom while drilling the wells. Fixed platform structures with production modules on top would be constructed over the wells that demonstrated large oil or gas reserves. Stiff-ened steel plate and circular steel shells like in ship con-struction, and large diameter steel pipes were the primary structure members used for early offshore structures. Na-val architecture, structures subjected to high winds, waves, and earthquakes are part of the “Design Criteria” for ocean structures.

In 1963, Kaiser – McDermott had the Design- Build contracts for Shell Oil and Chevrons’ Cook Inlet, Alaska offshore leases. They used Bill Martinovich and Earl & Wright to design and install these production platforms. According to Webb Hayes, Earl & Wright President, Bill’s swimming skills served him well when he was knocked into the freez-ing Cook Inlet water by cables that had come loose as he was stepping from the heaving work barge to the access lad-der on the platform. The barge crew threw him a life vest and then a rope. In that moment he had to decide what to reach for. If he had grabbed the life vest he would have been pulled away by the current and died a chilly death. Instead he grabbed the rope and held tight. “Fortunately,” Webb re-counted, “the barge crew was very quick in fishing him out of that frigid water.”

Deepwater drilling dictates that exploration drilling opera-tions be carried out from a floating vessel. Drill ships heave, pitch and yaw with each passing wave, and the industry needed more stable drilling platforms. A semi-submersible obtains its buoyancy from ballasted, water-tight pontoons located below the ocean sur-face and wave action. The semi-submersible concept obtains its buoyancy from ballasted, watertight, pontoons located be-low the ocean surface and wave action. Its stability comes from large diameter caissons located around the perimeter. The operating deck is located above the tops of the passing

waves, and those caissons and structural columns connect the pontoons and operating deck. In operation at deep draft, it motion is greatly reduced, and when the rig moves its lo-cation, the pontoons are de-ballasted so the rig pontoons float on the surface.

In 1961, Shell Oil successfully converted an existing sub-mersible rig into the first semi- submersible drilling unit for operation in the Gulf of Mexico. First generation semis were used in water depths of up to 600 feet. The industry was moving to develop oil and gas reserves that were discov-ered beneath deeper and deeper water. The bottom resting exploration platforms were modified to float on the water with positioning anchors and cables to hold position. This was the birth of semi-submersible.

The Sedco 135 exploration rigs were triangular, with large caissons and buoyant transportation pontoons at each cor-ner. They were designed to either sit on the ocean floor in up to 135 ft. of water, or drill when floating. Seven rigs were being constructed simultaneously, in five shipyards in five countries. The first one completed failed on its maiden voy-age, the rig sank, and most lives were lost. Southeastern Drilling Company in Dallas, Texas, or Sedco, faced ruin, and retained Earl & Wright and Bill to investigate. He looked at the structural configuration and floor plan of the platform, and identified the structural framing arrangement and joint details that appeared weak. Bill’s report stated that the structural configuration and resulting high stresses caused structural failure, and caused the vessel to tip, lose stabil-ity, and sink. Sedco accepted his report and the remaining six rigs under construction were modified. For future rigs, he changed the floor plan to allow drilling from the cen-ter of the rig rather than stern drilling, eliminated the sit-on-bottom work requirement, and reduced the rig overall height. The owner had Bill design four more rigs, with his modified design, that were constructed and commissioned for offshore work.

This experience led Bill to develop a rectangular floor plan drilling vessel, with four major steel shell caissons sup-ported on twin multiple compartment pontoons. It had improved deck load capacity, and self-propulsion at higher speeds between job sites. This was christened the Sedco 700 rig. Earl & Wright designed ten more of these rigs in the 70’s with Kaiser Steel constructing the 705 and 706 in Vallejo, California. And inevitably, Earl & Wright became part of Sedco.

Bill Martinovich and Earl & Wright established a reputation as a leader in offshore engineering. In 1971, Bill was the Chief Operating Officer and the principal technical leader of the firm. The company developed self-floating production platforms that included over 10 meter diameter stiffened steel shell legs.

14,000 hp ocean tugboats move the Thistle Field Platform to the North Sea Oil Production Site

Bill was responsible for over fifty oil and gas production structures engineered at Earl & Wright in the 60’s, 70’s and 80’s including: Maui A Gas Platform (360 ft. depth), New Zealand, Thistle Field, North Sea (510 feet depth), Nin-ian, North Sea (540 feet), and Rankine, Western Australia (560 feet depth), Esso Australia, Tuna & Mackerel Platform Designs, (1972); Shell U.K., North Sea, Platform Auk Deck Structures, (1972), Shell Canada, Eastern Canada, Platform Deck Design, (1970), ARCO, Cook Inlet Alaska, King Salmon & Spark Deck Structures, (1968); Shell, Cook Inlet Alaska, Platform C Deck Structures, (1966).

Typically, the platform structures were built horizontal in a dry dock, the dry dock would be flooded and the 15,000 ton rigs would float on the big legs. Very large ocean tug boats would tow the rigs to the site and a choreographed sequence of opening valves, flooding compartments, and ballasting would rotate the platform to vertical over the final position and ballasting completed. Two-meter diameter, 200 feet long steel pin and skirt piles were driven into the sea floor and grouted into pile sleeves to fix the platform.

The Offshore Energy Center Hall of Fame recognized Bill Martinovich for his pioneering work in the development of the Sedco 700 drilling platform. The Hall of Fame recogniz-es engineers and pioneers that took the industry to sea. The pioneers are individuals who distinguish themselves and become the character of the industry through their vision, drive, innovation and leadership. In 2000, Bill Martinovich, with Earl & Wright Consulting Engineers, a Sedco Compa-ny, was inducted into the Offshore Energy Center’s Hall of Fame for his pioneering work and contributions in develop-ing floating semi-submersible drilling platform technology and structures:

SEAONC Special Projects Initiative2014 Proposal SolicitationSEAONC’s Special Projects Initiative is intended to provide financial support for innovative projects that will serve SEAONC and its members through initiatives that improve and promote structural engineering practice. As outlined below, the scope of possible initiatives is broad with the goal of soliciting creative project proposals from SEAONC members on topics that could not typically be accomplished through the standard SEAONC committee structure. Sub-ject to the availability of resources and the quality of pro-posals, SEAONC expects to fund one or more projects per year, through one-year grants with funding up to $10,000 per project.

Project Ideas: This initiative covers a broad range of possi-ble projects with the key requirement that the projects ben-efit the SEAONC membership, the structural engineering profession at large, and/or the community at large on issues that involve structural engineering. Such benefits could oc-cur through the advancement of knowledge, the transfer of technology, and/or an increased awareness of the value of structural engineering. Suggested ideas may include but are not limited to the following:

• Research: Focused technical studies on structural engi-neering issues. Topics could include analytical studies on ways to improve specific building code provisions or research to facilitate the introduction of new concepts in design and construction. Alternatively, the research could involve field studies and collection of data on de-sign and construction practices. The grant funds could be used for project expenses, including compensation of the person conducting the research.

• Testing: Focused testing on an issue of engineering in-terest. Given the cost of testing, an SPI grant might increase the scope of an existing testing project or be used for preliminary tests to develop a larger proposal to funding agencies.

• Publications: Development of a unique publication of value to the SEAONC membership, the engineering community at large, and/or the public. The publica-tion could be a report or paper, published in either hard copy or electronic form.

• Community Outreach: Activities that could include plan-ning and conducting summit meetings on timely topics with leaders from industry, or conducting educational seminars for building code officials or key tradesper-sons whose work impacts the implementation of struc-tural design and construction.

• Business development: Activities that improve business opportunities for structural engineers at an aggregate level, but not limited to specific firms or individuals. One example might be to host a networking and educa-tional event for structural engineering clients, similar to software companies’ “client conferences.”

Eligibility: The Principal Investigator and Grant Applicant must be a current SEAONC Member.

Proposal Submittal Requirements: Proposal submissions shall consist of a Project Description, Budget and Budget Justification, and Qualifications for the Principal Investiga-tor and other significant project participants. The Proposal submission is limited to 5 pages (8-1/2 x 11 sheets, single spaced, 11 point font) excluding resumes and shall address (1) the objectives and scope of the project, (2) the project work plan, (3) project deliverables, such as a report, paper, seminar or other outcome, (4) a statement of how the activity meets the goals of the SEAONC special projects program, (5) the project schedule, and (6) a list of key personnel and their roles in the project.

It is expected that the awardee will as part of the project scope present findings at a SEAONC dinner meeting in ear-ly 2015, at a date mutually agreeable to SEAONC and the awardee. The Budget and Budget Justification is limited to 1 page and should include a breakdown and brief justification of how the requested funds will be spent. The Qualifica-tions of the Principal Investigator and other key investiga-tors should include a short (2-3 page) resume, including a statement on the unique qualifications of the individual as related to the project.

Submittal Process: The proposal, including all of the in-formation requested above and a cover letter, should be submitted electronically as a PDF file. Please upload your submissions to: http://airdropper.com/seaonc using the passphrase: specialprojects. Questions regarding the Spe-cial Projects Initiative should be sent via e-mail to office@seaonc.org. Upon submission you should receive confirma-tion of your proposal being received via Airdropper and an email confirmation from the SEAONC office. Please contact the SEAONC office, 415.974.5147 if you do not receive confir-mation. The submission due date for proposals is close of business on Monday, November 25, 2013.

Grant Awards and Funding: Proposals will be reviewed and award decisions will be made by the SEAONC Board of Directors. Award decisions are expected to be announced by mid-January 2014 with financial awards to commence by March 2014.

It is anticipated that the project funding will be awarded in three increments (1) initial award – 10% of total budget, (2) interim award made upon receipt of an acceptable progress report made to SEAONC, including accounting statement on funds expended to date – 40% of total budget, (3) final award made up submittal of final project report, including accounting statement on funds expended and summary of project deliverables – 50% of budget. The project is expected to be completed within one year of the award date; and for budgeting purposes, indirect (overhead) charges are limited to 10% of the award amount. SEAONC reserves the right not to make the final award payment if the final report is not submitted within 6 months of the end of the one-year award period. Any significant changes to the project scope, work plan and/or budget should be submitted in writing for review and approval by SEAONC.

Interim Progress Reports: The awardee should report the SEAONC Board of Directors on the progress of the proj-ect when milestones are reached or revisions to the project scope are required. Until after the completion of the project
