How It Works

Datasheet plus quotes in, structured tabulation out.

Upload

Step 01 — Input

Upload the P&ID page (or use one already analyzed by the P&ID Review Assistant). The system already knows the equipment, instruments, lines, and notes on the drawing.

Pick a tag

Step 02 — Equipment Selection

Choose the equipment tag (e.g., R-201, P-301, E-201, C-101). The right datasheet template, vessel, exchanger, pump, or compressor, is selected automatically from the equipment record.

Datasheet

Step 03 — Structured Output

A multi-section RFQ datasheet is emitted in your project layout. Every cell tagged extracted, inferred, standard, or TBD, with rationale, confidence, and a verbatim P&ID quote when extracted. Excel and JSON.

Core Capabilities

What the system does with your datasheet and the bids.

Per-Cell Provenance

Source-or-Quote

Four sources, no fifth

Every cell is one of: extracted (visible in the P&ID, with verbatim quote), inferred (specific service / duty rationale), standard (named code such as API 521, ASME VIII, API RP 941), or TBD (no defensible answer). Reviewers see at a glance which cells need engineer judgment.

Evidence-or-fail extraction

An extracted cell without a verbatim quote from the drawing context cannot pass the schema. Hallucinated extractions never reach the engineer; the drawing has to actually say it.

Equipment-Type Templates

Section Layout per Type

Vessels, exchangers, pumps, compressors

Per-type templates drive the section layout: vessels carry process conditions / geometry / nozzles / materials; pumps carry head / NPSH / sealing; exchangers carry shell side / tube side / TEMA; compressors carry stages / intercoolers / API 618. Sub-templates handle KO drums, strippers, intercoolers, and reboilers.

Repeatable blocks where the spec needs them

Nozzle schedules, gas compositions, compressor stages, and other multi-row groupings render as repeatable blocks within their section so reviewers see a real datasheet, not a flat list.

Drawing-Anchored Inference

Bounded Defaults

Inferred values cite a specific reason

When a value is not on the drawing, inference is grounded in the service: PSV set point fixes MAWP, reactor temperature plus margin gives design temperature, fluid identity at saturation gives vapour pressure. No 'typical for this service' with nothing named.

Standard defaults name their code

Where industry practice fills the gap, the standard is named: ASME VIII Div 2 corrosion allowance, TEMA RGP-T-2.4 fouling factor, API 660 Δp envelope, API 618 intercooler limits. The reviewer can accept, replace, or argue with a named source.

Excel and JSON Output

Drop-In Format

Single-sheet xlsx, one row per field

Output lands in a single-sheet workbook: section, field, value, units, source, confidence, rationale, evidence quote. Source column is colour-stripped (extracted / inferred / standard / TBD) so reviewers can scan for the cells that need them.

JSON mirrors the Excel structure

Machine-readable JSON ships alongside, useful for piping the datasheet into procurement systems, vendor portals, or downstream automation without re-keying values.

ROI Estimate

Estimated Datasheet Hours Saved

Based on typical equipment datasheet preparation effort: tags per project × hours per datasheet × revision cycles, reduced by the share of extraction, structured layout, and bounded inference the tool can pre-populate before the engineer opens the file.

You define safe. We map to it.

P&IDs and equipment specs are trade secrets. Before we talk controls, tell us what your IT, legal, and IP teams need to see. Common asks we have met: per-tag isolation, no model training, files deleted on delivery, EU-hosted processing, self-hosted deployment. The evidence below is what we can already point at.

No Model Training

Zero Retention

Uploaded drawings and datasheets are never used to train models. Period.

Isolated Sessions

Per-Tag Isolation

Each datasheet generation runs in its own session. No data crosses between projects, clients, or users.

Deleted After Processing

Automatic Cleanup

Files are removed from processing servers once the datasheet is delivered. Retention window configurable.

Encrypted and Authenticated

TLS/SSL + Your SSO

TLS/SSL in transit. Authentication via your existing sign-in. Every action logged for audit.

Full security posture, NIS2 control mapping, and subprocessors at /trust.

What Changes for Your Team

Concrete differences you will notice on the next equipment package.

Less Time Typing Datasheets

Speed

Tag transcription, line-condition lookup, and first-pass material / code selection happen before the engineer opens the file.

Same Layout, Every Tag

Consistency

Every datasheet runs through the same template (vessel, pump, exchanger, compressor) in the same order. No drift between reviewers, packages, or sessions.

Every Cell Traceable

Auditable

Each populated value carries source, confidence, and a P&ID quote when extracted. Reviewers can verify or challenge any cell against the drawing.

Inference Is Bounded

No Silent Defaults

Inferred values cite a specific service / duty reason; standards name the code. No anonymous 'typical' values appear in the draft.

TBD Stays TBD

Honest Gaps

If the drawing does not say it and no defensible inference exists, the cell reads 'no information available'. The engineer fills the gap, the tool does not invent it.

Works with Your Project Layout

Per-Project

Section order, units, and code stack follow the project's datasheet conventions, not a generic global template.

What RFQ Assistant won’t do

Where the tool stops and the engineer takes over. On purpose.

Does not size or selectEngineering judgment stays with the reviewer: The tool drafts the datasheet. Material selection, geometry sizing, scope of supply, and sign-off stay with the engineer.
No invented extracted valuesEvidence-or-fail: Every extracted cell carries a verbatim P&ID quote. The schema rejects extracted rows without one. The drawing has to actually say it.
TBD stays TBDNo silent defaults: Cells without defensible inference read 'no information available'. The tool does not fabricate values, interpolate from neighbours, or fill placeholders.
Not a vendor bid evaluationDatasheet, not TBE: RFQ Assistant generates the spec you send to vendors. Comparing returned quotes, deviations against spec, and bid selection are out of scope here.

Mission

The Tool Drafts. The Engineer Decides.

Most of the time spent producing an equipment datasheet from a P&ID is extraction and bounded inference: reading tags, copying line conditions, picking the right code for corrosion allowance, writing rationale for design temperature. Work that is repeatable, traceable, and verifiable. RFQ Assistant does that part: extract what the drawing says, infer what the service implies, name the standard when one applies, mark the rest TBD.

What it does not do: select the material, size the geometry, scope the package, or sign off on the spec. That stays with the engineer.

Frequently Asked Questions

A P&ID page (or one already analyzed by the upstream P&ID Review Assistant pipeline) plus a single equipment tag. The tool reads the equipment record, connected lines, instruments, and notes for that tag from the analyzed drawing context, then generates a datasheet for it.

Four templates ship in the demo: vessel (with sub-templates for KO drums and strippers), exchanger (with sub-templates for intercoolers and reboilers), pump, and compressor. New templates can be added per project, the schema is template-driven, not hard-coded.

One of four values: 'extracted' (visible in the P&ID context, requires a verbatim quote from the drawing), 'inferred' (reasoned from the service or duty, with a specific named rationale), 'standard' (an industry default with the standard named, e.g., API 521, ASME VIII Div 2, API RP 941), or 'TBD' (no defensible answer; the rationale reads exactly 'no information available'). The schema rejects extracted rows that lack a verbatim quote. The drawing has to actually say it.

No. Material selection, sizing trade-offs, and final geometry stay with the engineer. The tool will surface candidate materials with a service rationale (e.g., SA-336 F22V for high-T H₂ per API RP 941) and call out HTHA, NPSH, or fouling concerns, but the call belongs to the reviewer.

Cells without a defensible answer are marked TBD with rationale 'no information available'. They are not silently defaulted, not interpolated from neighbouring rows, and not infilled with placeholder values. The engineer sees a visible gap and fills it.

A single-sheet Excel workbook: section, field, value, units, source, confidence, rationale, evidence quote. The source column is colour-stripped so reviewers can scan for cells that need attention. A machine-readable JSON ships alongside for downstream procurement integrations.
