Design and Installation of Drilled Shafts: WED. 6/9, 8AM–12PM

Seminar Leader: Dan Brown, Ph.D., P.E., Dan Brown and Associates
This ADSC sponsored seminar will be presented by industry leaders in the design and installation of drilled shafts to provide deep foundation support of bridge structures. Presentations will focus on recently updated design and construction guideline specifications recommended by FHWA and AASHTO. Case histories and examples of design considerations for constructability and quality will be provided. Quality assurance, integrity testing, and load testing to provide cost effective design and installation applications will also be emphasized.

Seminar Outline:

1. “An Overview of New FHWA Drilled Shaft Design Manual, Including LRFD Application” – Dan Brown, Dan Brown and Associates.
2. “The Efficient Design Model for Drilled Shafts – A two phase process for maximizing your foundation design” – John Hayes, Loadtest, Inc.

Dynamic Testing and Analysis of Bridge Foundations WED., 6/9, 1–5PM

Seminar Leader:  Michael Morgano, GRL Engineers, Inc.
This seminar will focus on several current methods of deep foundation testing and analysis, including wave equation analysis of driven piles, high strain dynamic load testing of driven and drilled foundations, low strain (pulse echo) foundation integrity testing and cross-hole sonic logging of drilled shafts.  The Wave Propagation Theory will be discussed as it relates to practical applications of the dynamic testing methods.  The procedures used in various foundation testing and analysis methods will be discussed along with appropriate testing applications for various types of foundations such as driven piles and drilled shafts.  Case studies will be shared with the participants to illustrate these applications.  The AASHTO LRFD resistance factors for bridge foundations will also be discussed in the context of foundation testing and analysis.  The seminar goal is to prepare the participants for selecting the most appropriate method of deep foundation testing and analysis for their design challenges with an understanding of the implications for implementation within the context of AASHTO LRFD specifications.

Use of HEC-RAS for Hydraulics and Scour Analysis: WED., 6/9, 1–5PM

Presented by: Donna M. Newell, MS, PE – President, NTM Engineering, Inc.
Eric R. Brown, Ph.D. – Hydraulic Engineer, Federal Highway Administration
This workshop will discuss the applicability of existing FHWA HEC-18 Scour Methodologies and other tools to develop a scour analysis for your project site. Topics will include the use of hydraulic data from HEC-RAS; consideration of scour countermeasures based on FHWA’s HEC-23 publication; and ongoing scour research
