The SEAONC Fall Seminar will cover the state of the art practices regarding the design and construction of foundation systems. The presentations will address practical considerations in the selection of foundation systems as well as the analysis, design, detailing, and construction approaches of different systems including mat foundation, deep foundation, and excavation support systems.  The seminar will also allow the attendees to learn ways to improve collaboration between geotechnical and structural engineers, procedures to account for soil-structure interaction in analyses, and the process of developing waterproofing system design for foundations.

Evening 1 (November 12):
Improving Collaboration between Geotechnical and Structural Engineers — Bret Lizundia, Principal, Rutherford + Chekene Consulting Engineers

This presentation will draw on the lessons and recommendations from the NIST GCR 12-917-21 report developed as part of the ATC-83 project as well as the presenter’s experience in ways of improving geotechnical and structural collaboration, clarity in communication, and creativity in solving foundation design and construction challenges.

Seismic Design of Mat Foundations — Ron Klemencic, Chairman and CEO, Magnusson Klemencic Associates

This presentation will address some of the fundamental questions about the analysis, design, and seismic performance of reinforced concrete mat foundation systems, including determination and modeling of subgrade parameters, consideration of enhanced seismic design levels, variations in analysis options and stiffness assumptions, and detailing considerations.

Excavation Support Systems – Rob Jameson, Vice President of Construction Engineering, Malcolm Drilling Company

This presentation will describe the process of project evaluation, then selection, design and installation of suitable excavation support systems. The key factors which drive system selection will be highlighted, along with an overview of the geotechnical and structural concepts and methods employed in excavation support design. Current projects will be presented to illustrate the shoring system lifecycle.

Evening 2 (November 19):
Soil-Structure Interaction — Jonathan P. Stewart, Professor and Chair of Civil & Environmental Engineering, University of California, Los Angeles

This presentation will focus on recommended procedures for modeling soil-structure interaction for building structures as published in a report by NIST (2012). The presentation will include discussion of soil-structure system behavior, inertial interaction effects, kinematic interaction effects, and how such effects can be accounted for in response history analyses.

What Structural Engineers Need to Know about Waterproofing — Kenneth Klein, Principal, Simpson Gumpertz & Heger Inc.

This presentation outlines the process a consultant or designer undertakes in developing the below grade waterproofing system design and specific issues that will impact the membrane selection.

Deep Foundation — Stephen Harris, Principal, Simpson Gumpertz & Heger Inc.

This presentation will provide an overview of deep foundations, including various systems in common use in California, such as driven precast concrete and structural steel piles, augercast piles, cast-in-drilled-hole piles, and micropiles. The presentation will include a discussion on the behavior of each system, incorporate a review of current and proposed building code provisions for deep foundations, and will provide discussion of design and detailing approaches for each system.
