COURSE OBJECTIVES

This course is intended to develop in the civil engineering students the ability to analyze and design shallow foundations, mat foundations, earth retaining structures, sheet pile walls in water front structures, braced cuts, and pile foundations. Geotechnical and structural design using the standard code of the American Concrete Institute are covered in detail. Real-world applications and methods of foundation construction are also discussed. Four class hours and three lab hours. Prerequisite: CER 142. WAC: W1

COURSE GRADE

First Term Test = 20%

Second Term Test = 20%

Assignments & Quizzes = 25%

Project Geo-Challenge = 10%

Final Examination = 25%

NOTES

• Assigned homework are due as will be arranged. Late submission results in partial grade loss.
• Unannounced quizzes are probable to ensure students are keeping up with course work.
• Attendance of final exam is mandatory. If a student does not wish to solve given assignments, then this student may request that the assignments points be shifted to any or all of the three exams. Students may also elect to shift the points of any or both of the term tests to the final exam. This election, however, must be made before tests. Students should be aware of the risk involved with such decisions.

Project GeoChallenge

GeoChallenge is a challenging competition in the design and construction of foundations. It is for the Civil Engineering Senior students at Union College who are registered in the foundations course. Each and every student (or team) will be required to have one entry. The grading criteria is based on a formula that involves the predicted versus actual failure load.
