AVZ Selector
Engineering selection of ventilation equipment from a project PDF specification: Document AI, a catalogue core, explainability and manual control of exceptions.
Read the caseSPECTRA builds applied AI systems for companies that manufacture, extract, sell and ship. Not a demo of what a model can do, but a governed digital process: domain rules, integration into your system of record, and a person who controls the exceptions.

Below are examples, not a closed list. Pick the one closest to you: we will show the processes where AI already delivers a verifiable result rather than just speeding up correspondence.
Engineering and production processes where the answer has to be verifiable, not merely plausible.
| № | Scenario | What the AI takes on |
|---|---|---|
| 01 | Engineering selection and specs | Reads project documentation, structures the item list and runs selection against the manufacturer catalogues. |
| 02 | Quality control | Detects defects on the line and at intake from photo and video streams, and records deviations in the system. |
| 03 | Maintenance and tickets | Classifies requests, suggests the likely cause and the applicable procedure, and drafts the work order. |
Item lists, price lists and customer flow — wherever manual reconciliation eats a working day.
| № | Scenario | What the AI takes on |
|---|---|---|
| 01 | Supplier price lists | Normalises heterogeneous price lists and catalogues into a single product reference. |
| 02 | Assortment and ordering | Prepares stock and purchase recommendations from sales history and seasonality. |
| 03 | Customer service | A first-line AI agent answers from the knowledge base and hands complex cases to a person. |
The document flow between supplier, warehouse and the system of record.
| № | Scenario | What the AI takes on |
|---|---|---|
| 01 | Incoming orders | Extracts line items from email, PDF and Excel and moves them into the ERP without manual entry. |
| 02 | Document reconciliation | Matches waybills, invoices and contracts against the system of record and flags discrepancies. |
| 03 | Shipments and routes | Assembles trips and prioritises shipments within warehouse and transport constraints. |
Procedures, field data and safety on sites where mistakes are expensive.
| № | Scenario | What the AI takes on |
|---|---|---|
| 01 | Technical documentation | Answers from procedures, equipment datasheets and standards, with a reference to the source. |
| 02 | Shift reporting | Turns field notes and logbooks into structured reports for the control room. |
| 03 | Industrial safety | Monitors PPE compliance and presence in restricted zones from the video stream. |
Citizen requests, the regulatory base and internal document flow, all requiring traceability.
| № | Scenario | What the AI takes on |
|---|---|---|
| 01 | Citizen requests | Classifies, routes and drafts replies, naming the provisions that were applied. |
| 02 | Regulatory base | Finds and cross-references documents, showing revisions and related acts. |
| 03 | Document flow | Extracts data from incoming documents and tracks response deadlines. |
Not an off-the-shelf box, not a chat window on top of a model. We design the system around one concrete process: its data, domain rules, roles, exceptions and integrations.
Extracting and structuring data from PDFs, scans, emails and spreadsheets: specifications, waybills, contracts, equipment datasheets, procedures.
Agents carry out routine operations inside your systems within defined boundaries and hand a person the cases where the data is not sufficient.
The AI result lands in the system of record rather than in a chat: 1C, ERP, CRM, email, file storage and your existing document flow.
We take the current process apart and say plainly where AI will pay off and where the data and procedures need cleaning up first.
We start with one process
A pilot on a narrow section, a measurable result, and only then scaling to adjacent processes.
Discuss your processAI you can trust with part of an engineering process
AVZ Selector turns a project PDF specification into a ventilation equipment selection ready for engineering review. The AI recognises and structures the document, the domain core checks parameters against technical catalogues and runs the calculations, and the specialist gets an explainable result with exceptions flagged.
The AI reads the project. The engineering core runs the selection. The specialist controls the result.
The system can run fully autonomously. When a specification contains no items that call for engineering judgement, the whole cycle — from PDF upload to the finished table — runs without a human. Manual review kicks in selectively, only where the data is genuinely insufficient.
Source data arrives as PDFs with inconsistent tables, notation from different manufacturers, incomplete characteristics and OCR errors. Copying rows into Excel is not enough: the specialist has to determine the purpose of each item, normalise dimensions and flow rates, verify the operating point against technical data, and spot the cases where an automatic answer would be unsafe.
A hybrid AI system: probabilistic models handle the understanding of difficult documents, while formalised domain logic makes the technical decision.
Notation and dimension normalisation, equipment classification, flow and pressure verification, valve actuator sizing, fan model selection and assembly of the related components. Selection relies on digitised catalogues rather than free generation by a language model.
Source parameters, the operating point check, candidate comparison and the ranking rule.
A doubtful item stays in the result with a specific reason for manual review.
Sizes, operating ranges, pressure, rotation speeds and equipment power ratings.
“I set the task myself: selecting equipment from a project specification took our engineers hours, and I could see that artificial intelligence should be doing this work. But an owner’s decision is not enough — without competent specialists a system like this does not appear.
SPECTRA got to grips with the domain at the level of catalogues, operating points and valve actuators, and took the product all the way to industrial use. In parallel the team worked on digitising the plant: modern technology became part of everyday office work rather than a separate project.”

Read the caseSurveys and interviews in Telegram where the AI runs the open questions: it checks each answer against a completeness criterion, asks follow-ups within a set limit, and extracts a structured summary instead of raw text.
Discuss a taskTakes inbound calls and holds the conversation by voice: consultation, tyre selection, service booking. It acts on the company’s rules and records the outcome in telephony, amoCRM and the calendar — with no waiting on the line.
Discuss a task| № | Stage | What the client gets |
|---|---|---|
| 01 | Process audit | A process map, an assessment of data quality and an honest list of what can be automated now and what has to wait until the data is in order. |
| 02 | Pilot | A working system on one narrow section and a set of regression tests on your real documents. |
| 03 | Rollout | Integration into 1C, ERP and document flow, roles and permissions, staff training, and a procedure for handling exceptions. |
| 04 | Support | Quality monitoring, retraining on feedback, extension to adjacent processes. |
We do not promise an effect in percentages before the audit. The numbers appear after the pilot — on your data.
If your specialists read documentation, check data against catalogues and standards, run routine calculations and assemble the result in spreadsheets by hand — that process can be made faster, more transparent and more scalable.
