Estimating Capstone: Full Vehicle Estimate, Supplement, and Presentation

Estimating Capstone: Full Vehicle Estimate, Supplement, and Presentation

What This Lesson Is

This capstone lab puts every estimating skill from the course into one continuous, professional-grade exercise. You will inspect a vehicle you have never seen before, write a complete initial estimate, perform a supervised partial teardown, write a supplement for hidden damage, build a digital photo file, draft a customer summary, and then defend your work in a ten-minute formal presentation. This mirrors exactly what a repair planner or estimator does every day on the shop floor.

Safety Before You Touch the Vehicle

PPE is non-negotiable at every stage.

• Gloves and safety glasses must be on before you open a hood, crawl under a rocker panel, or handle any trim or glass fragments. Broken glass and sharp sheetmetal edges cause cuts without warning.
• If the vehicle has deployed airbags or any undeployed supplemental restraint system (SRS) components, do not probe, cut, or reposition those components. Note them in your estimate and flag for a qualified SRS technician.
• Before partial teardown, confirm the vehicle cannot roll: set the parking brake and place wheel chocks. If you must reach under the vehicle for any reason, it must be properly supported on approved jack stands—never on a floor jack alone.
• Disconnect the battery negative cable before removing any electrical connectors if your instructor directs it; follow the shop's lockout/tagout procedure for any powered equipment involved in the teardown.
• Keep the workspace clear of trip hazards. Removed parts go immediately to a designated staging area, not on the floor around the vehicle.

Phase 1 — Initial Estimate

Work systematically around the vehicle using the writing order your software follows (typically front to rear, exterior to structure, then mechanical and electrical). Do not jump to obvious damage first; panels you skip early are the panels you miss entirely.

Photo documentation starts before you write a single line. Capture four-corner overview shots, close-up damage shots with a reference scale, VIN plate, odometer, and any pre-existing unrelated damage. Label each image clearly in your photo file. Insurers and customers use your photos to verify every supplement you write later.

Classify every part decision correctly:

• OEM (Original Equipment Manufacturer): new part from the vehicle manufacturer's supply chain.
• Aftermarket (AM): new part from a third-party supplier; must meet insurer and state requirements.
• Recycled/LKQ (Like Kind and Quality): used OEM part in equivalent condition.
• Reconditioned: a used part that has been rebuilt to a standard.

Record labor operations as the estimating database presents them. Do not adjust labor times without a documented reason (such as a P-page note or a position statement from a manufacturer or I-CAR). Unadjusted database times are your baseline; supplements handle what the teardown reveals later.

Phase 2 — Teardown and Supplement

A supplement is a formal written amendment to the initial estimate. It exists because collision damage is often hidden behind panels that cannot be removed during the first inspection. Your supplement must:

1. Reference the original estimate number.

2. List every newly discovered operation with its own line (do not simply change totals).

3. Add updated photos showing the hidden damage before and after discovery.

4. Recalculate the total and flag any change to repair vs. replace decisions.

Common hidden-damage areas include the inner structure behind front fascias, apron and rail damage behind radiator supports, door intrusion beams found only when the door skin is removed, and water or rust behind rocker moldings. Write what you see, not what you expect.

The Customer Summary

The written customer summary translates your technical document into plain language. It must cover:

• What was damaged and what will be repaired vs. replaced, and why.
• Part type choices and a brief explanation of each.
• Estimated completion time (expressed as a range, not a single day).
• Any safety-related findings that affect drivability before repair.

Avoid jargon. A customer who reads "the LH front apron extension was replaced OEM per manufacturer position statement" learns nothing. Write instead: "We replaced the left front inner frame rail bracket with a new factory part because the vehicle maker requires it for that structural repair."

Phase 3 — Formal Presentation

You have ten minutes. Open by summarizing the vehicle and total damage scope in two sentences. Walk through the estimate in logical order, not line by line but by system (exterior panels, structure, mechanical/electrical, refinish). Anticipate challenges:

• An insurer reviewer will question part classifications, labor times, and any line item without documentation. Have the P-pages, position statements, or I-CAR technical references ready to cite by name.
• A customer will question why a part is being replaced rather than repaired, or why the estimate changed after teardown. Use your customer summary language.

Stay calm when challenged. If you cannot defend a line item, say so honestly and explain how you would research the answer. That professional honesty scores higher than a bluffed answer.

Scoring Overview

You need 22 of 30 points to pass, with no single category below 3 of 6. The five categories are: damage completeness, labor accuracy, parts classification, supplement accuracy, and presentation and communication. Review the instructor rubric before you begin Phase 1 so you know exactly what "professional standard" means for each category.
