Exley Spencer Lehman Invited Speakers The first conference day kicks off with presentations by invited speakers focused on important, local projects. Dynamic and Rapid Pile Loading Test Program at Terminal 5, Port of Seattle: Brice Exley, P.E., Hart Crowser, and Steve Spencer, P.E., Pacific Pile & Marine. This presentation discusses the engineering and construction aspects of a large offshore pile load testing program at the Port of Seattle. The program included low strain testing/signal matching and Rapid Load Testing of offshore prestressed concrete piles, and onshore open-ended pipe piles. Concrete Filled Steel Tubes and Their Connections for Efficient Deep Foundations in Regions of Moderate and High Seismicity: Dawn Lehman, Ph.D., University of Washington, and Amy Leland, Washington State Department of Transportation (WSDOT). This presentation summarizes over a decade of work sponsored by the Army, Caltrans and WSDOT, resulting in recent changes to the American Association of State Highway and Transportation Officials (AASHTO) bridge design specification and WSDOT bridge design manual. The presentation will discuss experimental and analytical results for the piles and connections. Seismic Design of Pile-Supported Port Structures: Geotechnical Per- spectives: Stephen Dickenson, Ph.D., P.E., D. PE, New Albion Geo- technical. This presentation focuses on common design challenges, pitfalls and lessons learned from numerous port and waterfront pro- jects from around the world. Recommendations will be presented for practitioners charged with geotechnical analysis of soil-foundation- structure interaction of pile-supported wharves and piers. Osterberg Lecturer DFI’s 2019 Osterberg Memorial Lecture is on Thursday, May 2, and is being broadcast as a live webinar. S amue l Pa ikowsky, Ph.D. , Department of Civil and Environ- mental Engineering at University of Massachusetts Lowell, has been selected as this year’s lecturer. Dr. Paikowsky is also the President of GeoDynamica and he has over 30 years of experience in geotechnical related consulting, research and engineering projects. He is an internationally renowned expert in the field of deep foundation, reliability-based design instrumentation, testing and analysis, and has been involved in projects worldwide. 26 • DEEP FOUNDATIONS • MAR/APR 2019 Dickenson Leland The lecture, Capacity Testing of Deep Foundations: Successes and Pitfalls, addresses the fact that a deep foundation remains a challenge as to the integrity and capacity of the constructed element. Dr. Paikowsky evaluates the various methods of capacity testing for their contributions, place in the profession and shortcomings. The Osterberg Lecture was established in honor of Dr. Jorj O. Osterberg, to recognize innovations in deep foundations construction related to engineering design, testing or education. Industry-Owner Collaborative Forum A forum to highlight the importance of industry-owner collaboration is being held following the Osterberg Lecture – and is being broadcast as part of the live webinar. The forum focuses on programs that provide unbiased industry input to enhance the value safety, sustainability and quality of technical foundation solutions. Collaborative vehicles being presented include Washington DOT’s industry outreach program; DFI’s Seepage Control Committee, Chennai Metro working group, and the International Groundwater Management Working Group; and PDCA’s Pile Advocacy Program. Webinar and in-person attendees will receive 1.5 PDHs for participating. Foundation Testing Panel Discussion On Friday, May 3, from 3:30 p.m. – 5:30 p.m., there is a panel discussion comparing foundation testing methods. The session focuses on the importance of understanding the pros and cons of foundation test methods to select one that ensures that a project’s objectives are met. Invited speakers Bert Miner, president of Robert Miner Dynamic Testing, and Mike Justason, program chair for Civil Engineering Infrastructure Technology at McMaster University will discuss the principles of high-strain dynamic testing methods as compared to rapid load testing methods, including the advantages and drawbacks, followed by a moderated Q&A session. Then, invited speakers Bernie Hertlein, senior consultant at GEI Consultants, and Gray Mullins, Ph.D., professor in the Department of Civil & Environmental Engineering at the University of South Florida, will discuss integrity testing covering crosshole sonic logging, low strain dynamic testing (also referred to as sonic integrity testing or pile integrity testing), thermal integrity profiling and gamma-gamma logging.
