PREFACE

The Soils and Foundations Workshop (NHI Course No. 132012) is a basic geotechnical

course which will provide practical knowledge for both generalists and those planning to

take more advanced geotechnical courses in the future. The workshop will be of most

benefit to bridge and foundation engineers; particularly those involved in the design and

construction aspects of highway projects. The course objective is to impart to the

participants the necessary knowledge and skills to determine the minimum level of

geotechnical effort needed on a highway project. The participants will develop knowledge

and appreciation of foundation activities in all project phases.

The course content follows a project oriented approach whereby the actual foundation work

for a bridge project is traced from preparation of the boring request, to laboratory work,

through design computations to construction activities. The concepts presented in each

lesson are concise and specifically directed at a particular operation in the foundation

design process. Recommendations are presented on how to efficiently layout borings, how

to minimize approach embankment settlement, how to design the most cost-effective pile

foundation, and how to transmit design information properly to construction. Basic

examples are included in several lessons for hands-on knowledge. Continuity between

lessons is achieved by sequencing the information in the normal progression of a

foundation design study. In each phase of the fictitious project the soil concepts are

developed into specific foundation designs or recommendations for that segment of the

workshop design problem.

All participants will be provided with a copy of the Reference Manual and Participant

Workbook. This Participant Workbook includes copies of visual aids and student exercises

that closely follows the presentations being made by the instructors. The student exercises

are designed to promote the interaction in the classroom, and to illustrate the basic

principles and analyses. Solutions to the exercises are included in the back of the
