DigiSurvey Knowledge · Engineering & CE

Surveying heavy equipment — parts, spot reports & a defensible loss.

A field guide for surveyors and loss assessors handling construction & engineering (CE) claims — excavators, cranes, loaders, dozers, graders, rollers, forklifts, transit mixers and DG sets. Every machine is broken down into the parts you actually inspect, with a method for writing a spot report that holds up, AI parts recognition that tags each photo, and the policy cover that decides admissibility. Figures and markers are illustrative.

In short

  • CE claims turn on machine-specific detail — you cannot survey an excavator the way you survey a car. Know the parts, inspect them in order, name them in the report.
  • A good spot report fixes identity (make, serial plates, hour-meter, rating), the peril and reasoned cause, a full GPS- and time-stamped photo set, and a preliminary estimate with its basis.
  • AI parts recognition tags each photo to the right part and offers the class checklist, so the annexure is complete and consistent — not a folder of IMG_1234.
  • Admissibility depends on the right cover: CAR/EAR, CPM, Machinery Breakdown, Fire, or Motor for road-registered machines. Separate accidental damage from wear and breakdown.
  • Capture on the phone or a self-survey link → the spot and final reports build themselves in DigiSurvey, ready to edit and export as a clean PDF with a video evidence QR.

Why CE equipment needs its own survey discipline

A motor car claim has a settled vocabulary — bonnet, fender, A-pillar — and a standard body of case practice. Construction and engineering plant does not forgive that shorthand. A ₹1.2-crore excavator and a ₹40-lakh hydra crane carry hundreds of named assemblies, each with a different failure mode, a different repair economics, and a different line in the policy. The difference between an accidental boom crack and a fatigue crack, or between a burst hydraulic hose and a seeping seal, is the difference between an admissible claim and a declined one — and it is the surveyor's photographs and words that carry that decision.

This guide gives you two things: the labelled anatomy of the ten machines you meet most often, and a repeatable method for turning a site visit into a report that an underwriter, a re-insurer or a court can rely on.

From site visit to signed report — how the software carries it

The workflow is the same for every machine class, which is what keeps the output consistent:

  1. Capture on site

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

  2. AI tags the parts

    The app recognises the machine class and labels each photo to the right component, and offers that class's inspection checklist so nothing is skipped on site.

  3. The spot report drafts itself

    Identity, perils, the tagged photo annexure and a preliminary estimate are assembled in an IRDAI-style spot-report format for you to review and edit.

  4. It carries through to the final report

    The same file becomes the final survey report — estimate, depreciation where applicable, total-loss assessment and salvage listing — exported as a clean PDF with a scannable walk-around video link.

You stay the assessor. The AI makes capture complete and fast; every figure, cause and conclusion is yours to set, edit and sign. The software never decides admissibility — it makes your reasoning easy to show.

Writing a spot report that holds up

A spot (preliminary) report is the first, fast record made at the site before anything is moved or dismantled. It is also the document most often tested later, so it has to be complete on the day. Work to a fixed order:

1 · Identify the machine

Make, model, year. Photograph the engine serial plate, the unit/chassis serial, the capacity/rating plate (kVA, tonnes, m³) and the hour-meter / odometer. On a road-registered machine, the RC and registration too.

2 · Fix the event

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

3 · Walk around before touching

Wide shots of the whole machine and the site, then mid-range, then close-ups — so position and context are never in doubt. Capture the scene before any recovery or dismantling.

4 · Document each damaged part

A dedicated, part-named photo of every damaged component, with a scale reference, noting whether the damage is accidental/impact or pre-existing wear.

5 · Link to the policy

Confirm the cover (CAR/EAR, CPM, MB, Fire, Motor), the sum-insured basis, the insured site and period, and — where relevant — the operator's licence.

6 · Preliminary estimate & reserve

A first loss estimate with its basis, and a clear flag if repair cost approaches machine value (possible total loss / CTL) so the insurer can reserve correctly.

Do

  • Shoot every serial and rating plate — identity is half the claim.
  • Keep an unbroken, time-ordered photo sequence.
  • Photograph an undamaged comparable area next to worn parts.
  • Record the hour-meter — it anchors wear-vs-accident.
  • State the basis for every cause and figure.

Don't

  • Don't let the machine be moved or washed before wide shots.
  • Don't caption photos IMG_1234 — name the part.
  • Don't mix breakdown with accident without saying which.
  • Don't edit or crop original evidence images.
  • Don't estimate from memory — measure and reference.

AI parts recognition — complete, consistent capture

The weakest link in a CE survey is usually the photo set: a hundred images with no names, gaps where a part was missed, and captions that mean nothing to the reviewer three months later. DigiSurvey closes that gap. It identifies the machine class, tags each photograph to the correct part — Boom, Arm, Sprocket, Alternator, Moldboard — and surfaces the inspection checklist for that class so you leave the site with a complete set. It helps flag damage and pre-fills the parts table that feeds the estimate. The result is an annexure that reads like a report, not a camera roll, and a file that is faster to finish and far harder to pick apart.

Policy & compliance — getting the cover right

Admissibility on CE plant is decided before you cost a single part, by matching the loss to the right policy:

CAR / EAR

Contractors' / Erection All Risk — covers plant and works at a project site during construction or erection. Site and policy period matter.

CPM

Contractors' Plant & Machinery — all-risks cover for the machine itself, on or between sites. Common for excavators, loaders, cranes.

Machinery Breakdown (MB)

Sudden, unforeseen internal electrical or mechanical failure of a unit — e.g. an alternator winding burn-out on a DG set. Not wear, not accident.

Fire & allied perils

Fire, lightning, explosion, and natural catastrophe (flood/STFI). Distinguish a fire origin from an electrical breakdown that followed.

A road-registered machine — a JCB, a hydra, a transit mixer — may additionally carry a motor policy, so a road accident and a site incident can sit under different covers. The surveyor's job is to name the peril precisely and separate accidental damage from gradual wear and from internal breakdown, because each points to a different section of cover. Work independently and factually, in line with IRDAI surveyor-and-loss-assessor practice, and let the GPS- and time-stamped evidence and the walk-around video carry the audit trail.

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

Frequently asked questions

Which policy covers construction and engineering equipment claims?
It depends on where the machine was and what happened. Plant on a project site is usually covered under Contractors' Plant & Machinery (CPM) or Contractors'/Erection All Risk (CAR/EAR); a sudden internal failure of a unit falls under Machinery Breakdown (MB); fire and allied perils cover burning, lightning and natural catastrophe; and a road-registered machine (JCB, hydra, transit mixer) can also carry a motor policy. Identify the correct cover, the sum-insured basis and the site/period before assessing admissibility.
What must a spot survey report for heavy equipment record?
Identity (make, model, engine and unit serial plates, hour-meter, rating plate); the date, time and GPS of the loss and inspection; the peril and a reasoned proximate cause; a full walk-around with wide, mid and close-up photos; a part-named photo of every damaged component noting accidental vs wear; the policy cover; and a preliminary estimate with its basis. Every photo should be GPS- and time-stamped.
How do you separate accidental damage from normal wear?
Wear is gradual, even and matches the hours run — polished links, evenly worn sprocket teeth, seeping seals, uniform tyre wear. Accidental damage is localised and consistent with the reported event — a fresh crack, an impact dent, a sheared pin, a burst hose with scorching. Record the hour-meter, photograph the damage next to a comparable undamaged area, and state your basis.
Can the spot and final reports be generated from this software?
Yes. Photos captured on the phone — or by the insured through a secure self-survey link — are GPS- and time-stamped, auto-tagged to parts, and assembled into an IRDAI-style spot report you edit. The same file carries through to the final report with estimate, depreciation where applicable, total-loss assessment and salvage listing, exported as a clean PDF with a scannable walk-around video link.
