P&ID Intelligence
Every P&ID already contains its material take-off. We read it.
Spec-driven MTOs from native CAD and vector PDF P&IDs — generated in minutes, reviewed by exception, with a traceable path from every output row back to the sheet that produced it.
inline components auto-assigned to the correct pipeline line number
material take-off across 120 P&ID sheets — down from three weeks manual
mechanical joints derived without manual intervention
less downstream procurement reconciliation effort
A P&ID is not a page of text with a diagram on it
Meaning lives in topology: which line a valve sits on, which header a branch belongs to, where one line number stops and the next begins. Fragmented CAD exports break those paths into disconnected segments. Intersecting utility headers invite line-hijacking, where a component is silently attributed to the wrong pipeline. OCR reads the tags; it cannot resolve any of this.
That is why a manual take-off still takes weeks — and why a confident wrong answer from a vision model is more expensive than no answer at all when the result feeds procurement on a capital project.
From sheet to spec-driven take-off in four steps
READ THE GEOMETRY EXACTLY
Native CAD and vector PDF layers are parsed directly — every line segment, curve and coordinate — so baseline geometry is exact, not inferred.
RESOLVE EVERY LINE, ACROSS EVERY CROSSING
Fragmented paths are traced back to their line-number tags and each inline component is bound to its parent pipeline, even where utility headers cross the run.
CLASSIFY THE SYMBOLS
Gate, globe and ball valves; concentric and eccentric reducers; spectacle blinds, spacers, vent and drain tap-offs — recognised dynamically against ISA-5.1 descriptors.
DERIVE THE JOINTS AND BUILD THE MTO
Line sizes and material classes are cross-referenced against project thickness tables, and every flanged component gets its mating flanges, gaskets and stud-bolt sets added automatically. The result is a spec-driven MTO in your SAP schema.
| Line Number | Component | Size | Qty |
|---|---|---|---|
| 6"-P-1201-A1A | Gate valve | 6" | 1 |
| 6"-P-1201-A1A | Ball valve | 6" | 1 |
| 6"-P-1201-A1A | Control valve | 4" | 1 |
| 6"-P-1201-A1A | Reducer, conc. | 6×4" | 1 |
| 6"-P-1201-A1A | Flange, WN | 6" | 6 |
| 6"-P-1201-A1A | Gasket, spiral | 6" | 3 |
| 4"-P-1202-A1A | Gate valve | 4" | 1 |
| 4"-P-1202-A1A | Spectacle blind | 4" | 1 |
| 4"-P-1202-A1A | Vent tap-off | 1" | 1 |
| 4"-P-1202-A1A | Stud bolt set | M20 | 8 |
Segments disconnected; header crosses the run.
Off-axis header excluded; gaps bridged deterministically.
Every component bound to its parent line number.
What changes for the engineering team
Manual symbol identification, line routing and take-off generation take weeks and surface errors late as schedule overruns.
A complete, spec-driven MTO for a 120-sheet package in eight minutes — reviewed by exception rather than re-checked sheet by sheet.
Intersecting utility headers and fragmented CAD lines misallocate components to the wrong pipeline.
Axis-locked topological resolution assigned 99.4% of inline components to the correct parent line; the remainder are flagged, never defaulted.
Omitted inline components and uncounted joint hardware force weeks of procurement reconciliation.
ASME B16.5 rules derive matching flanges, gaskets and bolt sets on every sheet — 18,000+ joints on the reference project, 85% less reconciliation effort.
Output an auditor will accept, in the systems you already run
Extraction is only half the job. What comes back has to land in a shape procurement, QA and finance can use without rebuilding it — and every number in it has to be traceable to the sheet it came from.
STRUCTURED MULTI-SHEET WORKBOOK
- •Raw extraction audit — every component with sheet, line number, size, schedule and source coordinate
- •Pipe class specification — the thickness and flange tables applied, per line class
- •Discipline roll-up — quantities consolidated by commodity for ordering
- •Exception review — the handful of ambiguous cases, each with its sheet and coordinates, so a reviewer goes straight to the element
ERP / SAP MTO PAYLOAD
- •Commodity grouping (e.g. VALVE-GATE), commodity shortcode (e.g. VG-CS-150), size arrays and a traceability remark naming the source sheet and the rule applied
- •Derived rows are labelled as derived and name the rule that created them, so a reviewer can distinguish what was read from what was calculated
ALSO AVAILABLE
- •Enterprise destinations: PLM, EAM and digital-twin destinations alongside SAP
- •Ingestion options: batch folder ingestion for whole packages or API submission per document

Deterministic first. Inference second. Nothing silently defaulted.
Where geometry can be resolved exactly from the vector layer, it is — with sub-point precision and no model in the loop. Language and vision models are reserved for the judgement calls: symbol semantics and classification. That boundary is what makes the output auditable.
Every output row carries its source sheet, its coordinates on that sheet, the classifier decision and the specification rule applied. Exceptions are surfaced rather than defaulted, so review effort concentrates on the few genuinely ambiguous cases. On the reference project, reviewers worked a short exception queue and a sampled spot-check was enough to sign the package off.
Inputs
Native CAD exports or non-raster (vector) PDF P&IDs
The platform reads the vector layer directly, so this is where accuracy is highest.
Scanned or flattened P&IDs routing
Scanned drawings are routed through the Engineering Drawing Digitisation module first; results then carry a per-field confidence and go to review where the read is uncertain.
Your pipe class / specification tables
(Or ASME B16.5 defaults) so the joint derivation follows your project rules.
Title-block exclusion zones
Configured once so drawing borders never contaminate the extraction.
Where it is used
Material take-off for procurement
Compile a complete, spec-driven, audit-traceable MTO from a multi-sheet P&ID package — joints included — so bulk orders are placed against a reconciled list, not a rebuilt one.
ERP and SAP harmonisation
Map line sizes, material classes and commodity codes straight into the enterprise MTO schema; no re-keying between engineering and purchasing.
Engineering-to-procurement handover
Give EPC contractors and suppliers one reconciled list at handover, with the exceptions already identified, and remove the bill-of-materials disputes that follow.
Multi-vendor package consolidation
Bring thousands of sub-vendor P&ID packages, in every format the supply chain uses, into a single material list — the same engine behind our EPC BOM-consolidation work.
Industries and operations that benefit
Purpose-built for capital-project environments where a take-off error becomes a procurement shortfall, a rush order or a budget deviation.
How this works with other iCaptur.AI modules
Enterprise-Grade Security
Engineering drawings are among the most sensitive documents an organisation holds. iCaptur.AI is built to be deployed against them — aligned to ISO/IEC 27001 and ISO/IEC 27701, with GDPR and HIPAA obligations supported and confidentiality designed into the pipeline rather than added at the perimeter.
A 120-sheet multi-train facility take-off, executed in a single automated run
An international EPC contractor deployed the P&ID Intelligence Platform to produce a complete material take-off for a multi-train hydrocarbon processing facility. The package featured fragmented CAD vector exports, intersecting utility headers and dense instrumentation clusters — the exact conditions that break conventional extraction.

Bring us a hard package
The interesting test is not a clean, born-digital sheet. It is the P&ID where the utility header crosses six process lines, the package with three title-block conventions, the export that arrives as ten thousand disconnected segments. Send us 20 to 30 of those and get the take-off back — with a like-for-like comparison against your manual result.
