The motor surveyor's guide — parts, AI damage & a clean assessment.

Everything a motor insurance surveyor assesses on a claim, in one place — the labelled anatomy of every vehicle class you survey, where the chassis and engine numbers hide, how AI marks the damaged parts and drops them into the estimate, how OEM labour rates are looked up, and how the spot and final reports come together. Written for licensed surveyors and loss assessors in India. Part labels and figures are illustrative.

In short

  • A motor survey is only as good as its photo set and part names — know the anatomy of each class, shoot it in order, name every damaged part in the report.
  • Fix the vehicle's identity first: registration, and the chassis (VIN) and engine numbers photographed at source, plus the odometer.
  • AI damage detection marks dented / scratched / cracked / broken parts and drops them into the estimate — a suggestion you verify; amounts stay blank until you confirm.
  • OEM labour rates are looked up by city, garage and class and drop into the editable sheet — you still decide repair vs replace, depreciation and the final amount.
  • Capture on the phone or a self-survey link → the spot and final reports build themselves, exported as a clean PDF with a GPS- and time-stamped video evidence link.

From the vehicle to a signed report — how the software carries it

Every claim runs the same path, which is what keeps the output consistent across classes and across surveyors:

  1. Capture on site

    Photograph and video the vehicle on your phone, or send the insured a secure self-survey link so they capture it for you. Every live image is stamped with GPS and time the moment it is taken.

  2. AI marks the damage & names the parts

    The AI recognises the vehicle and flags damaged panels and assemblies — dented, scratched, cracked, broken — labelling each correctly instead of leaving a folder of IMG_1234.

  3. Rates & the estimate fill in

    Detected parts drop into the parts table; the OEM labour-rate schedule is looked up by city, garage and class and the scheduled figure drops into the sheet for you to confirm.

  4. Spot → final report

    The spot report assembles in an IRDAI-style format; the same file becomes the final report with part-wise depreciation, excess, GST, total-loss / CTL working and a salvage listing — exported as a clean PDF with a video evidence QR.

You stay the assessor. The AI makes capture complete and the maths fast; every part, rate, depreciation and conclusion is yours to set, edit and sign. The software never settles a claim — it makes your reasoning easy to show.

What you can do with DigiSurvey on a motor claim

AI damage scan

Marks dented, scratched, cracked or broken parts on the vehicle, in seconds — you check and approve every line.

Spot & final reports

Spot, preliminary, final, re-inspection, total-loss and fee bill — all from the same survey, exported as clean PDFs.

Writing a motor spot report that holds up

The spot (preliminary) report is the first record made at the vehicle, before anything is moved or dismantled — and the document most often tested later. Work to a fixed order:

1 · Identify the vehicle

Make, model, variant and year. Photograph the registration number, the chassis (VIN) number, the engine number and the odometer at source (see the ID guide below).

2 · Fix the event

What happened, when and exactly where — the GPS of the loss and your inspection. State the proximate cause and separate it from contributing factors.

3 · Walk around before touching

Wide shots of the whole vehicle and scene, then mid-range, then close-ups of each damage — so position and context are never in doubt.

4 · Document each damaged part

A dedicated, part-named photo of every damaged panel/assembly, noting whether it is fresh impact consistent with the loss or pre-existing.

5 · Link to the policy

Confirm OD / TP cover, add-ons (zero-dep, engine protect, RTI), the IDV, NCB and the compulsory/voluntary excess that applies.

6 · Preliminary estimate & reserve

A first loss estimate with its basis, and a clear flag if repair approaches ~75% of IDV (possible total loss / CTL) so the insurer reserves correctly.

Do

  • Photograph the chassis & engine numbers and odometer — identity is half the claim.
  • Keep an unbroken, time-ordered photo sequence.
  • Name every damaged part; let the AI pre-list, then verify.
  • State repair-vs-replace and the rate basis for each line.
  • Flag fresh vs old damage explicitly.

Don't

  • Don't let the vehicle be moved or washed before wide shots.
  • Don't caption photos IMG_1234 — name the panel.
  • Don't accept an AI line without checking it.
  • Don't mix accidental damage with wear without saying which.
  • Don't edit or crop original evidence images.

Vehicle identification marks — where the numbers are

Fixing identity is the first job on any survey, and it is where disputes start when it is done loosely. The chassis (VIN) and engine numbers, and the manufacturer/compliance plate, sit in different places on each class — photograph each at source, legible, before you assess damage.

Vehicle identification marks location guide — VIN, chassis number, engine number, axle, gearbox and compliance plate locations for car, two-wheeler, three-wheeler, truck, bus and tractor

Policy & claims — getting admissibility right

Before you cost a panel, match the loss to the cover and the conditions:

OD vs TP

Own-Damage covers the insured vehicle; Third-Party covers liability to others. A surveyor assesses the OD side; note which applies.

Add-ons

Zero-depreciation (nil-dep), engine protect, return-to-invoice, consumables, roadside — each changes what is payable. Confirm from the policy.

Depreciation & excess

Part-wise depreciation by age/material, compulsory & voluntary excess, and row-wise GST — DigiSurvey computes these to the slab for you to verify.

Total loss / CTL

Repair ≈ 75% of IDV → constructive total loss, settled on IDV − excess − salvage. State the benchmark you used.

Separate accidental damage from wear and from consequential loss (e.g. re-cranking a flooded engine turns an accidental loss into a consequential one). Work independently and factually, in line with IRDAI surveyor-and-loss-assessor practice, and let the GPS- and time-stamped photos and the walk-around video carry the audit trail.

Illustrative only. Part labels, markers and figures here are for orientation. Assess each loss on its own facts, the vehicle's actual condition and the specific policy wording — not on this page.

Frequently asked questions

What should a motor spot survey report record?
Make, model and variant; registration, and the chassis (VIN) and engine numbers photographed at source; the odometer; the date, time and GPS of the loss and inspection; the peril and a reasoned proximate cause; a full walk-around; a part-named photo of every damaged panel noting fresh vs pre-existing; the cover confirmed; and a preliminary estimate with its basis.
How does AI damage & parts detection help?
The AI marks damaged parts — dented, scratched, cracked, broken — and drops them into the estimate's parts table, named correctly. It is a suggestion you verify: amounts stay blank until you confirm, and you add, remove or correct any line. With the OEM rate lookup, the assessment is faster and consistent while the judgement stays yours.
Where are the chassis and engine numbers?
They vary by class — car: windshield base + chassis member (VIN), engine block, door-frame compliance plate; two-wheeler: frame near steering head, engine on crankcase; truck/bus/tractor: right-side chassis frame and engine block, plus axle/gearbox/compliance numbers. The ID-marks guide above shows each location.
Can the spot and final reports be generated from this software?
Yes — photos captured on the phone or via a secure self-survey link are GPS- and time-stamped, the AI marks damage, and the spot report assembles in an IRDAI-style format you edit. The same file becomes the final report with depreciation, excess, GST, total-loss working and a salvage listing, exported as a clean PDF with a video evidence link.
