Measurement, photographs and a written scope at **$285 per hour**, one hour minimum, credited in full against an authorized repair. ## What is a structural teardown measurement? A structural teardown measurement is a documented diagnostic: the damaged area is opened, the structure is measured in three dimensions against factory data, and the findings become a written scope. Rancho Santa Margarita owners use this at our Yorba Linda shop to establish what is actually damaged before anyone commits to a repair. - Billed at the diagnostic rate, credited against an authorized repair - Produces a measurement print, a photo record and a parts position - Used for second opinions and for disputed total loss determinations - Measurement happens before disassembly goes any further than needed ### Key facts | Item | Value | | --- | --- | | Price range | $285 to $2,500 (1 to 9 hours at $285 per hour, one hour minimum) | | Rate | $285 per hour (Diagnostics, scan and programming department) | | Credit policy | Credited in full (Applied against an authorized repair at this shop) | | Deliverable | Measurement print, photo record, written scope, parts position | | Typical duration | 1 to 4 shop days (Access work on a large coach drives most of that) | Every difficult conversation about a damaged vehicle comes down to the same missing item: nobody established what was actually broken before opinions started forming. An adjuster wrote a number from photographs. A shop quoted from the outside. An owner was told the unit is a total loss and has no way to test that claim. All three problems have one answer, which is a measurement taken against factory data and written down. That is what this service produces. It is not a repair and it is not a step toward one by default. It is a diagnostic performed at the diagnostic rate, and a substantial share of the units that go through it never get repaired here at all, because the finding was that the damage was smaller than feared or that the unit should be settled instead. ## What a structural damage assessment produces You leave with a file, not with an opinion. Inside it is a measurement print showing actual dimensions against published factory specification at each control point with tolerance on every line, a layer by layer photographic record with timestamps, a written repair scope in sequence, a parts list with current lead times, and a stated position on whether repair is technically sound. That package exists to be used by somebody other than us. Adjusters read it. Other shops read it. Owners take it into a total loss negotiation. It is written to stand on its own, which is why the numbers are presented against a dataset rather than as a narrative about what a technician thought while looking at the vehicle. - Measurement print with actual, specification and tolerance per control point - Timestamped photographs of each layer as it was exposed - Written repair scope in the order the work would be performed - Parts list with current lead times on the long items - A stated repair or replace position supported by the numbers ## When you need one The most common reason is a disputed total loss. A carrier has made a determination, the owner disagrees, and the conversation has no factual anchor. A measurement print either supports the determination or contradicts it, and both outcomes end the argument faster than another round of estimates. The second reason is a stalled claim. Adjusters resist scopes that arrive without evidence, and shops resist writing detailed scopes on vehicles they have not opened. An assessment breaks that standoff by producing exactly the documentation the carrier says is missing, at a known cost, before anybody commits to a repair. The third is a purchase decision. Used coaches and fleet vans carry undisclosed structural repair history more often than buyers expect, and weld type, seam sealer profile and missing cavity wax tell that story clearly to somebody who knows where to look. Two hours here is a cheap answer to a question that otherwise gets answered after the sale. ## How the measurement is actually taken The method depends on the construction. A ladder frame chassis is read with laser and datum gauges along both rails, taking length, width, height and diagonal at each control point. A monocoque van shell is held in fixtures and read with an electronic measuring system in three dimensions. Upper body and opening dimensions on either construction are taken with a tram gauge against published figures. What does not vary is the reference. Every reading is compared against the manufacturer dataset, never against the opposite side of the vehicle. Side to side comparison is the single most common flaw in structural assessment, because a serious impact can move both sides and produce a vehicle that is symmetrically wrong. Symmetry is not specification. > **note:** Ask any assessment you are handed one question: what dataset were the numbers compared against? A report with no reference is a set of measurements with nothing to mean. ## Reading the report without a structural background Each line on the print names a control point, gives the published dimension, gives what we measured, and gives the tolerance the manufacturer allows. Anything inside tolerance is not damage no matter how the vehicle looks. Anything outside it is damage even if nothing is visible, and the size of the deviation tells you roughly how much work it will take to correct. The photographs answer a different question, which is where the damage was found and what condition the surrounding material was in. That is the part carriers scrutinize, because it is what separates impact damage from pre existing corrosion or from an older repair. We caption them rather than leaving a hundred images for somebody else to interpret. ## The assessment and your claim Carriers do not object to paying for damage. They object to paying for damage nobody proved. Almost every stalled structural claim we see is stalled at exactly that point: a scope exists, the evidence behind it does not, and the adjuster has no defensible way to approve it. An assessment supplies the missing half. It also protects the owner in the other direction. When a determination is made against you, the print is the only thing that lets you test it. Owners who accept a total loss valuation without measurement are accepting somebody else's arithmetic on a vehicle they own, and there is rarely a second chance to revisit it once the settlement is signed. ## What it costs and how the credit works The rate is $285 per hour from the diagnostics department, with a one hour minimum, which puts the range at $285 to $2,500 for one to nine hours. The whole amount is credited in full against an authorized repair performed here. If you take the file elsewhere or the unit is settled instead, the assessment is what you paid for and you keep the documentation. Hours are driven almost entirely by access. A cargo van where the damaged area is reachable in twenty minutes sits at the floor. A 43 foot coach where underbelly, interior flooring and cabinetry have to come out before a single control point is reachable sits at the top, and we scope that access before starting so nobody is surprised by either the cost or the state the vehicle is in. > **price:** There is no version of this that is unbilled. Every assessment, estimate and inspection here is charged and credited against an authorized repair. That policy is what keeps the diagnosis honest. ## What the assessment does not include It does not include repair. Nothing is straightened, welded, replaced or corrected during an assessment, because the point of the exercise is to record the vehicle as it currently is. It does not include putting removed components back to a finished standard either, unless that reassembly is separately scoped, since on a unit heading into repair it would be wasted work. It also does not include mechanical or systems diagnosis. Engine, transmission, house electrical, plumbing and appliance faults are separate work at their own rates. If a structural finding implicates one of those, we say so in the report and scope it separately rather than quietly folding it in. ## Bringing the unit in All of this happens at the Yorba Linda shop. Owners coming from Rancho Santa Margarita generally take the 241 to the 91, which is the practical route for anything over 30 feet because it avoids the surface street turns through Anaheim Hills. If the vehicle is not drivable, tell us at booking and we will coordinate the delivery rather than leaving you to arrange it around our schedule. Bring whatever documentation already exists: the carrier estimate, other shop quotes, photographs from the scene, and the claim number if there is one. The report is stronger when it can address the existing documents directly, and a second opinion that engages with the first opinion line by line carries far more weight than one written in isolation. ## Cost $285 to $2,500, based on 1 to 9 labor hours at $285 per hour. Written repair estimate is $150, credited in full against an authorized repair. All work is performed in shop. ## Questions and answers ### Is a structural assessment the first step of a repair? Not necessarily. It is a diagnostic that stands on its own, and a real share of the units we assess are never repaired here. Some turn out to have less damage than feared, some get settled instead. You keep the file either way, and it is written to be used by other parties. ### Do I pay for the assessment twice if I proceed with repair? No. The full amount is credited against an authorized repair performed at this shop. If you take the documentation elsewhere or the unit is settled, the assessment is what you paid for. There is no unbilled version, because an unbilled diagnosis is one nobody has time to do properly. ### Why not just compare one side of the vehicle to the other? Because both sides can be wrong together. A serious impact frequently moves the whole structure, and a side to side comparison then confirms a symmetry that is uniformly out of specification. Every reading is compared against the published manufacturer dataset, which is the only reference that cannot move. ### Can this help if I disagree with a total loss decision? It is the main tool for it. A determination made without measurement is an opinion, and the print either supports it or contradicts it. Owners who accept a valuation without testing it are accepting somebody else's arithmetic on a vehicle they own, and settlements are rarely revisited afterward. ### Can you check a used van or coach for hidden structural repair? Yes, and it is one of the better uses of a short session. Weld type that does not match factory joints, seam sealer with the wrong profile, missing cavity wax and corrosion that predates the stated history all tell the story. Two hours before purchase answers what otherwise surfaces afterward. ### How much of my vehicle will be taken apart? Only what the damage pattern requires, and it is agreed in writing before anything moves. Structure has to be visible to be measured, so trim, underbelly or flooring may come out. Reassembly to a finished standard is scoped separately, since on a unit heading into repair that work would be undone immediately. --- Source: [OCRV Center](https://ocrv.me/services/frame-and-structural-repair/structural-damage-assessment/).
