PREFACE

This manual is written for the laboratory component of a typical one-semester
undergraduate soil mechanics course as part of a typical civil engineering undergraduate
curriculum. The manual is written as a stand-alone document, but supporting media have
also been prepared to enhance the learning process. These resources are available online
at www.wiley.com/college/kalinski, and include the following:

 Video Demonstrations. Brief (10-20 minutes) video demonstrations have been
produced for each laboratory test. Each video describes the basic purpose of the
test, lists the required materials, demonstrates the step-by-step procedure, and
details methods for reducing the data. Viewing these videos prior to the lab will
help prepare the students for the lab exercise, and ultimately enhance the students’
learning experiences.

 Laboratory Data Sheets. Generic laboratory data sheets have been prepared for
each exercise, and are included at the end of each chapter. These data sheets are
intended for use by students, researchers, or practicing engineers. These forms
can also be downloaded off of the website listed above.
