How to Quote Reverse Engineering Jobs

Reverse engineering requests land in your inbox with a physical part and a simple ask: “Can you make this?” What follows is rarely simple. Between 3D scanning cleanup, CAD reconstruction decisions, and iterative inspection loops, these jobs consume more engineering hours than most shops budget. If you are quoting them like standard production work, you are leaving money on the table.

Separate the Scan from the Model

The first decision point is data acquisition. A structured-light scan of a simple bracket might take 30 minutes. A CT scan of an internal assembly with hidden geometries could run four hours plus preprocessing. Quote the scanning method explicitly — equipment time, fixturing, and the technician skill level required. Do not bundle it into a generic “digitizing” line item.

Define the CAD Output Up Front

Customers often assume “reverse engineering” delivers a parametric SolidWorks model with full feature history. What they actually need might be a dumb STEP file for 3-axis machining, a watertight STL for 3D printing, or a 2D drawing set for legacy documentation. Each deliverable carries a different effort level. Parametric modeling with design intent (fillets, draft angles, standard hole sizes) can take 3–5x longer than a direct surface-to-solid conversion. Spell out the modeling philosophy in the quote so scope creep stays visible.

Build In Inspection Loops

No scan-to-CAD workflow is perfect on the first pass. You will compare the model back to the mesh, find deviations, adjust, and repeat. Budget at least two inspection cycles for geometric parts and three to four for organic or worn surfaces. Include the cost of CMM time or handheld probe verification if the customer requires a first-article report. If they skip formal inspection, note the risk in your terms.

Account for Wear, Damage, and Ambiguity

The part on your bench is rarely the nominal design. It has wear marks, previous repairs, or manufacturing defects. Decide — and document — whether you are reconstructing the as-built condition or the as-designed intent. The former is faster; the latter requires engineering judgment on every feature. When the customer cannot clarify, quote a decision gate: deliver a preliminary model for review before committing to full parametric reconstruction.

Price the Engineering Risk, Not Just the Hours

Reverse engineering carries inherent uncertainty. A seemingly simple housing might hide internal ribs that require destructive sectioning or CT scanning. A legacy part may reference obsolete standards. Add a contingency line (15–25% of engineering hours) labeled “investigation buffer” rather than padding every task. It keeps the quote transparent and gives you a mechanism to approve extra scope without rewriting the PO.

Use a Template That Forces the Right Questions

Standard RFQ forms miss reverse-engineering specifics. Build a checklist into your quoting workflow: scanning method, target file format, parametric vs. dumb solids, inspection requirements, wear/intent decision, and destructive testing allowance. When the estimator checks each box, the quote assembles itself with realistic hours and clear exclusions. Solvi’s customizable quote engine lets you embed this logic once so every reverse-engineering RFQ follows the same rigorous path. See how it works.

Reverse engineering will never be a commodity service — and it shouldn’t be priced like one. Structure the quote around the actual decision points, and you protect both your margin and your reputation.
