Course Objectives

It is presumed students will spend a minimum of 2 hours outside study for each hour in class in order to meet the following objectives. The student will be able to: upon receipt of construction drawings and specifications, prepare a complete construction estimate for both residential and commercial projects including but not necessarily limited to the disciplines of site development, excavation, concrete, masonry, ornamental metal, electrical, plumbing, HVAC, rough carpentry, finish carpentry, moisture and thermal protection, doors and windows, interior finishes, landscaping, miscellaneous equipment, and overhead/profit. In addition, the student will be proficient with Timberline estimating software.


Attendance Policy
Students are expected to attend all class sessions and to arrive on time. If you are unable to attend a class you are responsible for all material covered in that class. Missed quizzes and exams may NOT be “made up” at a later date. Attendance is taken at each class. The third unexcused absence will result in a one-letter grade reduction to the student’s grade. The fourth absence (excused or not) will result in the automatic withdrawal of that student.


Letter Grades: Breakdown:
A: 90-100 Participation 10%
B: 80-89 Class Assignments/Quizzes 40%
C: 70-79 Midterm 20%
D: 60-69 Comprehensive Final Exam 30%
F: 59 or below

Grading will NOT be done “on a curve.” All quizzes, mid-term and final examinations will be closed book, closed note tests of knowledge. All material either in the textbook or discussed in class may be appear on any quiz or examination. Daily quizzes may be given prior to the lecture. Therefore, it is essential that students review the assigned material before coming to class.

Academic Integrity: Students are responsible for the integrity of their academic work. With that principle as a firm starting point, this course will also encourage students to learn from each other. Personal experiences and insights of the members of the class constitute an important resource for each other, which we will utilize as fully as possible.

In their written work, students should use an appropriate footnote or reference system for citing others’ work. Plagiarism is forbidden at Triton College. If a student uses another’s work without giving credit, and this is proven, the student could receive an automatic “F” in the course.
