SuperPile ’20 | Virtual Conference Schedule* | Day One | Thursday, June 18 11:00 a.m. - 11:05 a.m. Conference Introduction Lyle Simonton, P.E. | Subsurface Constructors Inc. 11:05 a.m. - 12:35 p.m. Panel Discussion | Moderator: James Morrison, P.E., P.Eng. | COWI North America, Inc. Panelists: Randy Essex | Mott MacDonald, Jeramy Decker, Ph.D. | Kiewit, Vic Donald, P.E. | Terracon, Conrad Felice, Ph.D., P.E., P.Eng., D.GE., F.ASCE. | C. W. Felice, LLC, Richard Kalson, Esq. | Benesch, Friedlander, Coplan & Aronoff LLP Geotechnical Baseline Reports Geotechnical and legal experts will discuss the meaning, benefits, and challenges of using a Geotechnical Baseline Report (GBR) for foundation projects. A GBR is a concise document developed by the design team and the project owner based on geotechnical data reports, previous experience, and engineering judgment. The GBR provides a contractual representation of the anticipated underground conditions for the project and fairly allocates the risk from the subsurface uncertainties between the owner and the contractor. GBRs were developed for and are used mainly for tunneling and underground structures, and this panel will discuss their potential use in preventing or resolving disputes for foundation projects. 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. - 12:50 p.m. DFI Women in Deep Foundations Committee – New Video Release Helen Robinson, P.E., D.GE | GEI Consultants, Inc. 12:50 p.m. - 1:20 p.m. The Incremental Rigidity Method – More-Direct Conversion of Strain to Internal Force in an Instrumented Static Loading Test Van Komurka, P.E., D.GE, F.ASCE | GRL Engineers The Incremental Rigidity (IR) method can be used to determine the relationship between axial rigidity and strain at individual strain gage levels. From this relationship, measured strains can be converted to internal forces without having to know either a deep-foundation element’s elastic modulus or its cross- sectional area. The IR method for converting strain to internal force in an instrumented static loading test is presented, including assumptions, uncertainties, limitations, and best practices highlighted with case histories. 1:20 p.m. - 1:50 p.m. Pipe Piles in Plastic Soils: Effect of Installation Activities on Side Resistance Steve Saye, P.E. | Kiewit Infrastructure Engineers Pile installation methods influence measured side resistance of driven pipe piles bearing in plastic soils. Construction influence factors to modify a SHANSEP- based side resistance method calculation to consider and estimate the influence of specific pile installation actions on the resulting calculated pile capacity are suggested. 1:50 p.m. - 2:20 p.m. Impact of Heave on Permanently Cased Drilled Shaft Axial Capacity in Sand Glen Bellew, P.E. | USACE-Kansas City District Heave occurred during construction of a permanently cased drilled shaft in an alluvial deposit. The shaft was load tested to failure and, as expected, it experienced axial failure at a load significantly lower than the originally predicted ultimate capacity of the shaft. A subsurface investigation was conducted within days of the load test to better understand the impacts of heave on soil conditions in the immediate vicinity of the test shaft and evaluate the apparent effects of heave on the permanently cased shaft. 2:20 p.m. - 2:25 p.m. 2:25 p.m. - 3:25 p.m. Closing Remarks Theresa Engler | Executive Director, DFI Networking Happy Hour with Trivia Game Hosted by ICE® 32 • DEEP FOUNDATIONS • MAY/JUNE 2020 - International Construction Equipment, Inc. *Subject to Change
