Learner Outcomes (Course Objectives)

Outcome Assessment Strategy 1. Identify and describe sources of soils, how Students will work in groups in the soils these soils are deposited and their physical laboratory to classify soils per the Unified engineering properties as they relate to the Classification System, including the Unified Classification System. Atterberg limits and sieve analysis tests. Students will also demonstrate proficiency on written exams. 2. Properly calculate engineering properties of Students shall demonstrate proficiency on soils, including water flow through soil using written homework assignments and exams. Darcy’s equation, moisture content, densities Students shall also perform some of these and void ratio, based on information obtained tests and calculations in the laboratory. from reading a soil boring log. 3. Demonstrate an understanding of soil Perform the Standard and Modified compaction and the relationship of soil density Proctor tests in the laboratory and to moisture content. demonstrate proficiency on exams and homework assignments. 4. Properly calculate stress distribution in soils Students shall demonstrate proficiency on beneath both a point and distributed foundation homework assignments and written exams. load using influence coefficients, the Boussinesq Equation and chart and a Newmark chart. 5. Properly calculate consolidation and Students shall demonstrate proficiency on settlement of a foundation over a clay stratum, both exams and written homework as a function of time, using an “e log p curve”. assignments. 6. Demonstrate an understanding of soil strength Students shall demonstrate proficiency on due to cohesion and internal friction, the tests both exams and written homework used to determine this strength and how this assignments. relates to the ability of the soils to support a variety of structures. 7. Properly analyze and design both shallow and Proficiency shall be demonstrated by deep foundations, including spread footings, designing both shallow concrete footings piling and piers. Also, properly determine at and deep piling on homework assignments rest, active and passive lateral soil stress on and exams. Lateral forces due to soil and earth retaining structures. water on retaining walls shall also be determined in homework assignments and on exams.

Grading:

Student work will be assigned points as follows:

Homework (including lab assignments and projects) 120 pts Exam No. 1 100 pts Exam No. 2 100 pts Final Exam 120 pts Total Points 440 pts

Letter grades will be assigned based on the percentage of total points that each student earns during the quarter: 92-100% A 90-91% A- 88-89% B+ 82-87% B 80-81% B- 78-79% C+ 72-77% C 70-71% C- 68-69% D+ 62-67% D 60-61% D- Homework: 1. Homework will be assigned on a weekly basis and will be typically due the following week. All work shall be done in pencil on engineering paper, using standard engineering format, unless otherwise noted. This format includes:  Name, date, course and assignment number on the FIRST sheet. Name and page number/total number of pages on EACH additional sheet.  Given: A brief statement of the problem, including a sketch if appropriate. If you can’t draw a straight line use a straightedge.  Find: A statement indicating what the problem is asking to find.  Solution: A neat step-by-step solution to the problem, including diagrams, units and an underlined or boxed answer.

2. Professional work is imperative at the senior level, and a portion of your homework grade will be based on appearance of the assignments.

3. Assignments are due at the beginning of the class period and no late work will be accepted.

4. Some homework assignment may not be graded.

Exams: Exams will be given as indicated on the attached schedule.

Laboratory: This course includes a series of laboratory exercises that will be conducted primarily in the soils lab located in Hogue Room 105. These exercises are designed to complement the classroom information presented in this course by providing a “hands-on” learning environment. All students using the lab must follow proper safety procedures at all times. No open-toed shoes will be allowed in the lab. Please refer to the separate lab handout for more information. Some lab times may be used as a recitation period to work problems and answer questions.

Academic Honesty Policy: Students are clearly expected to do their own work and not copy the work of others. Evidence of copying, including any computer files, cheating or using writings of others without proper citations will result in a failure for the specific assignment. Successive evidence of copying, including any computer files, cheating or using writings of others without proper citations during the curriculum of the Construction Management program will result in loss of a student’s major status. Your attention is directed to Appendix B of the current CWU Catalog for additional information regarding this topic.

Disability Services: If you have a disability and require accommodations for this course, please speak to me privately as soon as possible so that your needs may be appropriately met. If you have not already done so, you will need to register with Disability Services (DS). DS is located in Bouillon 140. Call (509) 963-1202 or email [email protected] for more information.
