Introduction/Context / This lesson will instruct the student on how to recognize and apply overlap deductions, included operations, and additions. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in a Collision Repair Facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident or create customer satisfaction issues.

Content/Presentation/Demonstration Outline
Teach students that included operations are labor times that are part of an operation. These are listed in each collision estimating guide section. The “P” pages list included operations. Explain that more specific included operations are listed in collision estimating guide sections. For example, tell them that in the “P” pages, front bumper R&I is not included in radiator support replacement. However, on a ‘98 Escort in the front inner structure section, R&I front bumper assembly is listed as included in radiator support R&R. Tell them that by checking the “P” pages and notes in each section, they can determine what labor is included.
Explain that additions must be made if an operation is required but not listed as included. For example, tell them that a pickup truck cab corner replacement does not include bed R&J. If the bed needs to be removed for access when replacing a cab corner, let them know that an addition for bed R&J must be made. Refinish labor time is listed in collision estimating guides. There are additions and overlap. For example, let them know that if a fender is to be replaced, the guide may list 2.5 hours to repaint the outside of the fender. The fender edges need to be painted also, so the guide lists 0.5 hours to edge the fender. Total refinish time would be 3.0 hours. Let them know that when more than one panel, not including painted bumpers, is refinished, an overlap deduction should be made for each panel.
Inform them that if the painted panels are adjacent, a 0.4 hour deduction is made. If the panels are not adjacent, a 0.2 hour deduction is made. For example, tell them that if the right fender, right door and right quarter panel are to be repainted, the refinish time for the fender is 2.5 hours, the door is 3.0 hours, and the quarter panel is 3.0 hours. Total time is 8.5 hours. An overlap of 0.8 is taken: 0.4 hours for the door and 0.4 for the quarter panel. So the refinish time is calculated at 7.7 hours.
Explain that clearcoat time is added to the refinish time at the rate of 0.4 per refinish hour for the first panel, plus 0.2 per refinish hour for additional panels. In the side repair example, tell them that the clearcoat time would be 2.5 x 0.4 = 1.0 for the fender, the first major panel + 3.0 x 0.2 0.6 for the door and 3.0 x 0.2 = 0.6 for the quarter panel. The total clearcoat time would be 1.0 hour + 0.6 hour + 0.6 hour or 2.2 hours. Explain that three- stage paint is figured in a similar manner except the numbers are 0.7 per refinish hour for the first panel + 0.4 per refinish hour for additional panels. Two-tone is figured at 0.5 per refinish hour for the first major panel + 0.3 per refinish hour for additional panels. Blended panels are figured at 0.5 per refinish hour.

Evaluation and feedback Prior to Testing or Lab Work
STUDENT ASSESSMENT:(Assess student progress with performance criteria.)
IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)
REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)
