[Live Webinar] “Conflict of Interests” Corrupts Engineering and Endangers Public Safety- The Case of the New SAS Bay Bridge

Intended Audience: All Engineers
Credits: 2 PDH Units
When: Wednesday 5/27. 2 – 4 pm EST


We promise you a very special webinar .  This is not your ordinary boring ethics webinar.  We are very proud to bring this webinar to you.

The 1989 Loma Prieta earthquake resulted in the drop of a 50-feet long segment of the San Francisco Oakland Bay Bridge, an 18,000 feet long steel bridge. The earthquake caused the collapse of the concrete double-deck viaduct killing 42 people.  California Department of Transportation (Caltrans)  undertook a multi-billion dollar retrofit and replacement program, which included the replacement of the Eastern Spans of the Bay Bridge with a single-tower self-anchored suspension bridge.  The bridge took 15 years of construction, more than twice the original plan. At the cost of $6.5 billion, a 2,500%  cost overrun from the initial estimate of $250 million, the SAS Bay Bridge ended up having more than 16 structural severe problems including fracture of the anchor rods of the main tower, which occurred even before the bridge opened to traffic. This webinar traces the root cause of the problems of SAS Bay Bridge mainly to the “conflict of interest” in the engineer members of various advisory and peer review committees of Caltrans. The engineers, charged with independently overseeing and peer-reviewing the seismic safety aspects of the new bridge, were themselves receiving contracts to do the design and testing work on the same bridge that they were peer-reviewing.

Professor Astaneh will present the results of his extensive failure analysis of both the 1936 East Spans of the San Francisco Bay Bridge, which sustained relatively minor damage but was demolished and replaced with the new Self-Anchored Suspension (SAS) Bay Bridge, which opened to traffic in 2013.

He will show, through analysis of the seismic performance of both 1936 bridge and the 2013 replacement, how “conflict of interest” in the members of the top advisory boards and the peer review committees was at the root of design and construction problems of the new bridge.  Some critical elements of the new SAS Bay Bridge, such as the 3-inch diameter high-strength anchor rods of the tower and west-support,  fractured even before the bridge was opened to traffic.

Learning Objectives

Upon completion of the course, the student should understand:

  • What does Canon 3 of Code of Ethics: “ Engineers shall issue public statements only in an objective and truthful manner “ means?.
  • What does Canon 4 of Code of Ethics: “Engineers shall act for each employer or client as faithful agents or trustees” means?.
  • Why “Avoiding Conflict of Interest”  is one of the fundamental principles of the Code of Ethics for Engineers.
  • What are the “legal” and “ethical” responsibilities of engineers to “Avoiding Conflict of Interest.”
  • How not “Avoiding Conflict of Interest” was at the root of many problems and failures of the new SAS Bay Bridge.
  • How not “Avoiding Conflict of Interest can lead not only to corruption and fraud but to safety problems.
  • How the 1936 East Spans Structure of the Bay Bridge performed during the 1989 earthquake and how it would perform during future earthquakes after a relatively limited retrofit.
  • How might the 2013 New SAS Bay Bridge perform during future earthquakes?.
  • What “conflict of interest existed in the members of the Caltrans Seismic Advisory Board and Caltrans Seismic Safety Peer Review Panel concerning planning, design, testing, and construction of the SAS Bay Bridge.
  • What lessons can we learn from the case of SAS Bay Bridge to “Avoid Conflict of Interest.”

  1. Another great webinar from Professor Abolhassan Astaneh-Asl, Ph.D., P.E.


    This is the second recent webinar I’ve taken from this professor and it was very good. I would strongly recommend this course to anybody looking for an interesting and for the most part inexpensive way to earn ethics PDH credits. There may be cheaper options out there if you’re just going through the motions and doing the very least amount of work possible. However, if you want to learn about actual events that were shaped negatively by unethical engineering behavior AND do it an interesting, entertaining, and educational way then THIS IS THE WAY TO DO IT. I will be watching for and then enrolling in any future webinars offered from this professor.



    but distressing story of corruption within the engineering community, told by one with first-hand knowledge of the events. I would have liked more information on if and how the state licensing board addressed the issue.

  3. The Case of the New SAS Bay Bridge - Based on Personal Experience


    A case study of engineering ethics based on the personal experience of the instructor on a major California bridge project. The instructor personally observed the ethical issues during his work on the project and therefore brings his close-up and detailed perspective. He is able to relate the story of the project with details that illuminate the ethical concerns and keep the course interesting.

  4. Disturbing case history


    Sobering story of a critical bridge. Dr. Astaneh is very knowledgeable on this project. It was a little slow getting going. would like liked more time for Q&A but glad I was able to join in.

  5. Great Story of Politics, Greed , and Engineering


    Excellent course about how politics, greed, and unethical practices can bilk taxpayers and lead to public endangerment.

  6. Excellent Presentation


    It is a shame for such a critical infrastructure of transportation for the Bay Area, not to mention the investment of our country’s resources, that more care was not taken in the selection of the design type! Kind of boggles the mind!

  7. Conflicts of Interest The Case f the NEW SAS Bay Bridge


    Well presented by an expert in the field.
