TUTORIAL HELP:

Tutorial hours will be announced in class.  Students with difficulties are encouraged to come during the tutorial hours.

 

GRADING:

The grade will be decided based on the following scheme:

Homework and Class Participation    20 % (Attendance will be taken during each class.)

3 Exams                                              60 % (20% each)

Final Exam                                         20%

Total                                                   100%

 

The grade scheduling:

A         =          88 to 100         C         =          65 to 69

B+       =          82 to 87           D         =          60 to 64

B         =          76 to 81           F          =          59 or less

C+       =          70 to 75           W        =          Voluntary before deadline (school schedule)

Incomplete = given in rare instances where the student is unable to attend or otherwise do the work of the course due to illness, etc.  The grade must be made up in the next semester by completing all of the missed work.

 

QUIZZES and FINAL EXAM:

Other than calculator, no electronic device, storage medium, or accessory of any kind, is allowed to be used during quizzes and final exam.

 

HOMEWORK: 

Homework will be checked and returned the following week.  To obtain full credit, you must submit the work on time and in the proper form.  A minimum of 70% of the homework must be submitted to receive a passing grade in the course.  Late homework will get reduced points.

 

The following are to be observed when handing in homework for grading.  Failure to do so may result in significant deductions in the homework grade.                               

  1. On the top of each page, PRINT your name (LAST, FIRST), section (or class day and time, like Tuesday 10am), problem number, date, and page number (1 of 7, 2 of 7, etc.).  
  2. The problems must be presented in numerical order as assigned. If more than one problem on the same page, a clear dividing line is required between problems.  Lettering and numbers are to be neat, clear and legible. 
  3. Draw neat, clear FBDs and kinetic diagrams as required.  Use a straight edge if needed.
  4. Box in the final answer accompanied by its units (and direction if needed). 
  5. Staple the problems in proper numerical order with a single staple in the upper left-hand corner.

 

SPECIAL NOTES:

 

*The University Code on Academic Integrity (NJIT Honor Code) will be upheld in this course. 

Any violations will be brought to the immediate attention of the Dean of Students

*Students will be consulted on any substantial changes to the course syllabus.

CEE Mission, Program Objectives and Program Outcomes

 

The mission of the Department of Civil and Environmental Engineering is:

 

·        to educate a diverse student body to be employed in the engineering profession

·        to encourage research and scholarship among our faculty and students

·        to promote service to the engineering profession and society 

 

Our program objectives are reflected in the achievements of our recent alumni.  

1 – Engineering Practice: Recent alumni will successfully engage in the practice of civil engineering within industry, government, and private practice, working in a wide array of technical specialties including construction, environmental, geotechnical, structural, transportation, and water resources.  
 

2 – Professional Growth: Recent alumni will advance their skills through professional growth and development activities such as graduate study in engineering, professional registration, and continuing education; some graduates will transition into other professional fields such as business and law through further education.  
 

3 – Service: Recent alumni will perform service to society and the engineering profession through membership and participation in professional societies, government, civic organizations, and humanitarian endeavors.  
 

Our program outcomes are what students are expected to know and be able to do by the time of their graduation:
