  1. Assignments
    1. Out-of-class assignment: Out-of-class reading assignments: Weekly reading assignments from the textbook that correspond to the classroom lectures and drawing assignments currently taking place.
    2. In-class activity: In-class drawing assignments: The method of teaching is primarily one of simulating an actual engineering firm. The drawings are assumed to emanate from the engineer's office, where the system analysis and specifications have been completed. The drawing is then issued to the drawing room where the detailer (student) will prepare plans and elevations of the equipment required by the installation. Specifications are explained and the students use a workstation to create the required documents. Drafting problems assigned will simulate drafting room assignments in piping systems and HVAC systems. The instructor acts as the design engineer in charge of the computer room and during classroom time, circulates from station to station to assist individual students in their calculations and drawing solutions. a. Single line & Double line piping system drawings b. Isometric piping diagrams c. Spool details d. Large-scale HVAC plan/layout or elevation drawings of installation detail
    3. In-class activity: In-class calculation sheets: Several assignments will include calculations to size & select components. These calculation sheets outline the student's approach for the selection of equipment involved. The student then performs the calculations necessary to select the components necessary for the solutions of the assigned problem. The student must also work out a satisfactory geometrical arrangement of the equipment used involved in the problem.
  2. Evaluation
    1. Other: Calculation sheets: Calculations and plans are reviewed for accuracy of arithmetical calculations, adequacy of equipment, accuracy of dimensioning, practicality of assembly, selection of "best size" and conformance to economical construction practices.
    2. Other: Drawing assignments: The principle emphasis of the course is on developing an ability to do industry standard piping and HVAC system drawings. Each of drawing, with calculations, is reviewed in detail by the instructor and returned with written comment. The students CAD drawings will be evaluated for accuracy of dimensions, system function, and adherence to ANSI drawing standards. Final drawings will be plotted.
    3. Other: Mid-term: Two-hour examination that will test the student's capability to apply the principles they have learned to problems that range from "easy-to-difficult". Furthermore the exam will test the student's familiarity with terms used in the construction industry. All quizzes and exams are graded and returned with comment to the student. Discussion of test grading is invited from the student.
    4. Other: Final exam: Two-hour comprehensive examination that will test the student's capability to apply the principles they have learned to problems that range from "easy-to-difficult". Furthermore the exam will test the student's familiarity with terms used in the construction industry.
    5. Other: Observation of classroom activity: Evaluation will be based on the instructor's observations of the student's responses to: a. Direct questioning of assigned reading materials. b. The instructor working out problems incorrectly on the board, charging students with the responsibility ofpicking up the errors as the improper solution is disclosed.
