SuperPile ’20 | Virtual Conference Schedule* | Day Two | Friday, June 19 11:00 a.m. - 11:05 a.m. Conference Introduction Lyle Simonton, P.E. | Subsurface Constructors Inc. 11:05 a.m. - 11:35 p.m. Micropiles for Permanent Support Applications in Sedimentary Formations Jesús Gómez, Ph.D., P.E., D.GE | GEI Consultants Over the past 15 years, hollow bars have been increasingly used for foundation of new structures and underpinning of existing footings. Speed of installation, large geotechnical capacity, and ability to be installed with batter are distinct advantages. This presentation will highlight Type-B micropiles used in granular, sedimentary formations with temporary casing. 11:35 a.m. - 12:05 p.m. Reducing Risk and Conservatism in Drilled Shaft Design: A Case Study Justin Toney, P.E. | Quanta Subsurface and Brock Wallis | MJ Drilling A collaborative, value engineering approach was taken on a new 345 kV transmission line outside downtown Chicago. The foundation designer and contractor worked together with the owner to optimize ten large diameter drilled shaft designs for site-specific conditions and contractor capabilities. This case history highlights how foundation efficiencies can be realized when stakeholders are able to coordinate throughout the design and construction process. 12:05 p.m. - 12:35 p.m. Using Thermal Integrity Profiling (TIP) to Monitor Shaft Cooling System for Large Diameter Drilled Shafts David Schoen, P.E. | S&ME, Inc. Large diameter drilled shafts can meet the criteria for mass concrete, and South Carolina DOT is considering provisions to limit the maximum overall temperature and the maximum differential across these shafts. To meet a project’s requirements, a design-build team developed a cooling system installed in the shafts and used thermal integrity profiling to assess the effectiveness of the cooling system. 12:35 p.m. - 12:40 p.m. BREAK 12:40 p.m. - 12:45 p.m. Welcome Back Paul Axtell, P.E., D.GE | Dan Brown and Associates, PC 12:45 p.m. - 2:15 p.m. Panel Discussion | Moderator: Gerald Verbeek | Allnamics Pile Testing Experts, BV Panelists: Ryan Allin, P.E. | Pile Dynamics, Marcel Bielefeld, MSc, MScBA | Allnamics Erik Loehr, Ph.D., P.E. | University of Missouri, Robert Simpson | Load Testing Consulting, Ltd. Horses for Courses - Pile Testing A wide range of load and integrity testing methods can be applied for foundation testing. Not every method is suitable for every foundation test. A good understanding of each of these methods allows the appropriate test method(s) to be selected. This panel discussion will explore the features, limitations, and appropriate use of static load testing as compared to bi-directional load testing, and low strain dynamic testing as compared to thermal integrity profiling. Extensive Q&A will be held deepen understanding of the methods. 2:15 p.m. - 2:20 p.m. 2:20 p.m. - 3:20 p.m. Closing Remarks Theresa Engler | Executive Director, DFI Networking Happy Hour with Trivia Game Hosted by PierTech Systems, LLC DEEP FOUNDATIONS • MAY/JUNE 2020 • 33 *Subject to Change
