ASCE Seattle September Dinner Meeting Register

The Path to Opening Seattle's Downtown Tunnel and Removing the Alaskan Way Viaduct

Speaker: Chris D. Brown, P.E., SR 99 Demolition, Decommissioning and Surface Streets Engineering Manager, Alaskan Way Viaduct Replacement Program, Washington State Department of Transportation
When: Wednesday, September 12, 5:30pm - 8:00pm
Where: Mirabella, 116 Fairview Ave, Seattle, WA 98109

Description: The State Route 99 Alaskan Way Viaduct has been a fixture on Seattle's waterfront and a vital north-south route through downtown for more than 60 years. The Washington State Department of Transportation (WSDOT) is replacing the seismically vulnerable structure with the nation's largest-diameter bored tunnel and other projects that together will reshape the SR 99 corridor.
Join us for an update on the program, including the upcoming SR 99 closure leading to tunnel opening and the approaching removal of the viaduct!

About the Speaker: Chris Brown is the Demolition, Decommissioning and Surface Streets Engineering Manager for the Alaskan Way Viaduct Replacement Program. He has worked for WSDOT for 19 years and has design, construction, contract administration and contract management experience working as a field inspector, design engineer, office engineer, and project engineer.
Prior to the SR 99 Demolition, Decommissioning and Surface Streets Project, he worked on the SR 520 Floating Bridge, Everett HOV, and SR 532 Corridor Improvements Design Build projects. He was also the engineering manager for the SR 99 Tunnel Project. Chris is a licensed civil engineer in the state of Washington and holds a bachelor's degree in civil engineering from Washington State University.

ASCE Geotechnical Group - September 2018 Dinner Meeting Register

Region-Specific Probabilistic Liquefaction Hazard Analysis: Overview of the Liquefaction Pilot Study Being Performed in the Netherlands Due to Induced Seismicity

Speaker: Professor Russell A. Green, PhD, PE
When: September 27, 5:30pm - 8:30pm
Where: Best Western Plus Executive Inn, Seattle 200 Taylor Ave N Seattle, WA 98109 United States

Abstract: The Groningen gas field in the Netherlands is one of the largest in the world and has produced over 2000 billion m3 of natural gas since the start of production in 1963. The first earthquakes linked to the gas production in the Groningen field occurred in 1991, with the largest event to date being an ML3.6. In response to concerns about the induced earthquakes, the field operator is leading an effort to quantify the seismic hazard and risk resulting from the gas production operations, to include the assessment of the liquefaction hazard. However, due to the unique characteristics of both the seismic hazard and the geologic profiles/soil deposits in Groningen, direct application of existing liquefaction evaluation procedures was deemed inappropriate. Accordingly, efforts were first focused on developing Groningen-specific relationships for evaluating liquefaction potential of the region. The probabilistic liquefaction hazard is being calculated using a Monte Carlo method, wherein for each event scenario, the Groningen-specific relationships are being used to compute the factor of safety (FS) against liquefaction as a function of depth and corresponding Ishihara Inspired Liquefaction Potential Index (LPIish) hazard curves are being computed. The results from this study are forming the basis on which decisions will be made regarding the need for implementing mitigation measures. The overall approach being used in this pilot study can be adopted to assess the probabilistic liquefaction hazard worldwide.

Biography: Dr. Russell Green is a Professor of Civil Engineering at Virginia Tech, Blacksburg, VA, in the Geotechnical Engineering Program area. He was previously on the faculty at the University of Michigan and held visiting faculty positions at Chuo University, Tokyo, Japan and the University of Canterbury, Christchurch, New Zealand. The primary focus of Russell's research is in the areas of engineering seismology, geotechnical earthquake engineering, and soil and site improvement. He has participated in post-earthquake investigations in the US, Iceland, Haiti, Japan, and New Zealand. Russell received his bachelor's degree in civil engineering from Rensselaer Polytechnic Institute in 1992, his master's degree from the University of Illinois at Urbana-Champaign in 1994, and his PhD in 2001 from Virginia Tech. Russell is a registered professional engineer in Virginia and a veteran of the United States Marine Corps. Also, Russell is the recipient of the 2016 ASCE Norman Medal, among other awards for research and teaching.

ASCE Legislative Committee - Volunteers Needed

Volunteer Needs

ASCE Seattle Section is searching for volunteers to assist with the Legislative Affairs Committee. The level of Involvement can vary and and can include providing engineering judgement on current legislative issues to assisting with lobbying.

The new Committee Chairperson is Savannah Linders and the new State Advocacy Captain is Dr. Conrad Felice.

Below is a description of the work that the Legislative Committee participates in.

The Legislative Committee functions in the political arena. The committee can become active in federal, state, county or other governmental issues that are of interest to the profession (such as university engineering budget considerations, issues that affect the practice of or employment of civil engineers, and environmental issues of significance to the profession). The committee is responsible for disseminating information from the AELC pertaining to state legislation. In recent years, the chair of the Legislative Committee has also been the AELC representative. If they are different, the Legislative Committee chair is an alternate to the AELC and shall be responsible for keeping abreast of current activities of the AELC.

The committee reviews proposed legislation and comments on it with regards to its effect on the civil engineering profession. The committee may request the Board take an official stance on certain legislation that is being proposed as appropriate. The committee and its members may also be called upon to testify at Legislative hearings or for other governmental committees (it must be noted that if such testimony is not previously approved by the Board or general membership, such testimony cannot represent the official position of the Seattle Section and is as an individual). The committee should work toward establishing a key contact group of members of the Society who have contacts with elected officials and who would be available to communicate the position of the Section. The committee is generally active prior to and during the sessions of the state legislature. The committee at times seeks the advice of other Section committees that may be more versed on a particular legislation topic. The committee typically sends at least one representative to the Society's annual Legislative Fly-In in Washington D.C.
