Objective. Students produce a complete, printable estimate for a real collision-damaged vehicle using CCC ONE or equivalent software that correctly includes all labor, parts, refinish, and sublet lines.
This lesson, its worked examples and its practice questions has not yet been verified by a certified examiner or master technician in the trade or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
A collision repair estimate is a legal and financial document. It tells the vehicle owner what will be repaired, the insurer what will be paid, and the shop what work must be done. A complete estimate protects everyone. Missing a single labor operation or the wrong parts choice can cause a repair to stall, a supplement to be filed, or a technician to absorb an unfunded hour. This lab puts all earlier estimating skills together into one finished, printable document.
Before approaching either assigned vehicle, put on safety glasses and gloves. Damaged vehicles may have sharp metal edges, broken glass fragments, deployed airbag components, and leaking fluids. Walk around the vehicle without leaning on panels — a damaged body structure can shift. Do not reach into areas you cannot see clearly. If you notice a leaking fluid, a deployed airbag module with exposed inflator, or a high-voltage orange cable on a hybrid or electric vehicle, notify your instructor immediately and do not proceed until the vehicle is confirmed safe. Treat any vehicle with unknown fuel-system damage as a potential ignition hazard — no open flames or sparks nearby.
Use the systematic walk-around method you practiced in Lesson 2. Begin at the front bumper and move clockwise. Note every damaged component on your inspection worksheet before opening the software. Photograph or sketch the damage zone so you have a reference when you are at the workstation. Record part names, not just locations — write "left front door outer panel" not "the dent by the handle." Missing damage at the inspection stage means missing lines in the estimate.
In CCC ONE or equivalent software, select New Estimate and search by VIN whenever possible. The VIN decodes the exact year, make, model, trim, engine, and factory option packages. Trim and option packages affect which parts appear in the database — a vehicle with a factory sport package may have a different bumper cover part number than the base trim. Verify the decoded information against the vehicle's door-jamb sticker and the physical vehicle. A wrong vehicle profile produces wrong part prices, wrong labor times, and a potentially unacceptable estimate.
Work through your inspection worksheet from front to back, top to bottom. For each damaged component, select the correct operation type:
The software's labor time database (such as the CCC or Mitchell labor guide) populates a suggested labor time for each operation. Accept the database time unless you have a documented reason to adjust it — and document that reason in the estimate notes.
Every panel that is replaced or repaired must be refinished. The software calculates refinish time based on the panel and operation. Add blend operations on adjacent panels when the color on the new or repaired panel will not match the surrounding finish without feathering the color into the neighbor panel. A common missed line is failing to blend the adjacent quarter panel when a door is refinished — leaving it out creates a visible color mismatch after delivery.
Also check for:
Some operations cannot be performed in the body shop and must be sent to a specialist. Common sublet examples include wheel alignment, glass replacement by a glass vendor, frame or unibody straightening if performed by an outside service, and mechanical repairs to suspension or steering. Enter sublet lines with the vendor type, description of the work, and estimated cost. Omitting sublet lines means the shop absorbs that cost or the customer is surprised by an invoice they did not expect.
Before printing, run the software's internal audit or review function. CCC ONE and Mitchell both flag common errors such as:
Work through every flag. Some flags are informational and can be overridden with a note; others indicate a genuine error that must be corrected. An estimate submitted to an insurer with unresolved audit flags may be rejected or delayed.
Print the completed estimate and review it one final time for legibility — is the vehicle identification clear? Are totals visible? Then prepare your five-minute verbal walkthrough. For three lines you will explain your decision: why you chose R&R instead of repair (cost to repair exceeds part price, or damage exceeds one-third of the panel), why you added a blend line (adjacent panel color match required), and why a sublet line is included (alignment required after frame correction). Clear reasoning on line choices is the mark of an estimator an insurer and a customer can trust.
Answer each question, then check it. Nothing is recorded; this is your own practice.
