Worked example

One concept, from requirement to indicative estimate

A finished, pre-built electrical and controls concept you can explore end to end — no sign-up, nothing to build. Every output was produced from a single connectivity model by the same deterministic engines the studio uses, so you can see exactly what the platform generates before you start your own.

Sample data

This is a pre-built example project, not a customer design. Every output on this page was produced server-side from one connectivity model by the studio’s deterministic engines. Nothing here calls an AI model, a database or your account.

Step 1 · Input

Start from a requirement

A short electrical and controls brief for an engineer-to-order pump-station control panel. In the studio the assistant extracts structure from a spec like this; here it is pre-loaded so you can jump straight to the outputs.

SAMPLE PROJECT — fixture data, not a customer specification.

Pump station control panel, 400V 3-phase 50Hz TN-S supply.
Loads: 2x 7.5kW borehole pumps (VSD driven), 1x 3kW dosing pump DOL,
1x 5kW ventilation fan, lighting & small power 2kW, control supply 24Vdc via 10A PSU.
Panel: mild steel IP54, wall mounted. Standards: BS 7671, IEC 60204-1.
Control: start/stop per pump with latching contactors, overload interlocks,
running lamps, e-stop circuit. Fault level and cable route lengths not yet known.

Step 2 · Scope

A connected scope and equipment register

Equipment resolved from the brief and organised by area. Every item carries its origin (how it entered the model) and its confirmation state — AI-proposed facts are never silently promoted to confirmed.

Step 3 · Concept

Block cable diagram and cable schedule

The diagram and the schedule are two views of the same projection of the connectivity model — the edges and the rows are the same connections by construction, never separately maintained.

Step 4 · Studies

Panel arrangement and general-arrangement drawings

Panels and their contents are projected from the same model into indicative general-arrangement drawings and a system arrangement across zones. These are concept aids using series-level footprints, not checked GA drawings.

System arrangement

Step 5 · Studies

BOM candidates from an approved library

Series-level candidate references from an internally approved component library — never auto-selected, never a quotation, and honest about gaps where the library has no coverage. An engineer confirms exact catalogue numbers before anything is purchased.

No library coverage yet — the register shows this honestly as a gap for the engineer to source, rather than inventing a part.

Step 6 · Studies

Interface and completeness checks

Deterministic checks over the model surface provisional connections, unresolved routes and interface mismatches. These are completeness and interface warnings, not a standards-compliance verdict.

Step 7 · Estimate

An indicative estimate assembled from evidence

Costs are assembled from the model plus manually evidenced sample prices and engineer allowances. Prices here are illustrative sample figures, not supplier quotations; unpriced items stay visible so coverage is honest.

Kind	Description	Qty	Line cost	Confidence

Allowance	Install, test & commissioning	1 sum	£2,500 to £4,000	allowance
Allowance	Concept-stage contingency	1 sum	£1,500 to £2,500	allowance

Indicative total

£11,020 to £15,520

Priced lines only · no currency conversion

Coverage

5 priced (sample) · 6 unpriced · 3 allowances

Unpriced items stay visible — coverage is reported honestly.

Not included

Installation, commissioning and site labour (unless entered as an allowance)
Cable lengths and containment quantities (routes are not modelled)
Delivery, duties, taxes and escalation

Indicative estimate ranges assembled from manually evidenced prices and engineer allowances only. Not a quotation, tender or budget commitment; coverage is partial (unpriced items are listed), prices are not confirmed, current or complete, and no currency conversion has been applied.

Step 8 · Evaluate & export

Assurance stays visible and independent

Four assurance states are tracked separately and never collapsed. Outputs stay marked preliminary until a customer records acceptance under their own process — and optional independent Gedelec review never gates generation, evaluation or export.

Calculation reproduced

The figure re-computes from pinned, versioned modules.

Method validated

The engine method has evidence beyond a single run.

Standards rules checked

Rule ids and coverage recorded — never protected standards text.

Engineering accepted

The customer records their own decision — never Gedelec approval.

Open technical query carried with the concept: What is the prospective fault level at the incoming supply? (assumed 10 kA for the sample) Nothing is silently resolved — the query travels with the model until an engineer answers it.

Also in the studio

More deterministic tools on the same concept

Single-line diagrams and control (ladder) schematics are drawn by their own deterministic renderers. Run them directly to see the same engine-draws approach applied to a supply/board model or a control sequence.

Build your own concept

Start from your own spec and the studio routes it through these same engines — no sign-up needed to begin. Your data stays yours; this example is the only pre-built, sample-labelled project on the site.
