Electrical and controls preliminary design software

From specification to a costed preliminary design pack.

Attach a specification or describe the system. Gedelec structures the requirements, runs deterministic engineering calculations and assembles traceable preliminary outputs for your engineer to review and accept.

What you receive

What your preliminary design pack contains

One project model. Connected engineering outputs. Each output is derived from shared project information, reducing duplicate entry and helping schedules, diagrams and estimates remain aligned.

  • Structured requirements

    Requirements extracted from the specification, each carrying the wording it came from, held as proposed until confirmed.

  • Load schedule

    Connected and diversified loads with kW, kVA and current, built by a versioned calculation module.

  • Connectivity and diagrams

    Block cable diagrams and system arrangements drawn from the project model.

  • Cable schedule

    Each connection as a scheduled cable with its service, ends and preliminary sizing.

  • Panel and system arrangements

    General arrangements with components positioned and dimensioned for each panel.

  • Candidate equipment and BOM

    Candidate equipment with ratings and quantities, each line tracing back to the part of the design that required it.

  • Assumptions and open questions

    Every assumption recorded as an assumption, and every open question raised rather than silently resolved.

  • Indicative concept estimate

    An indicative estimate built from the bill of materials and declared allowances, presented as a range with its confidence stated.

Who uses the outputs

One project, read by the whole delivery team

The same project information supports different roles across the delivery team, from the engineer confirming technical assumptions to the director reviewing cost exposure.

  • Design engineer

    Inspect requirements, assumptions, calculations and unresolved technical questions.

  • Estimator

    Review quantities, allowances, exclusions and the basis of the concept estimate.

  • Project manager

    See what has been confirmed, what remains open and which outputs may need recalculation.

  • Procurement

    Review candidate equipment, ratings, quantities and provisional commercial assumptions before RFQ preparation.

  • Panel builder or integrator

    Understand the likely panel, cable, device and integration scope earlier in the project.

  • Owner or managing director

    See likely scope, uncertainty and cost exposure before committing substantial detailed-design effort.

A worked example

Pump station control panel

SAMPLE - Demonstration data, not a real project input.

One project, walked from the specification to the decision record. Every figure below is produced by the same deterministic modules that build the public worked example, so what you see here is what the platform actually generates.

  1. Step 1: Requirements extracted

    Requirements are pulled out of the specification and set down as a register, each carrying the wording it came from so it can be checked against the source. They are held as proposed until an engineer confirms them.

    12 equipment items identified and registered

  2. Step 2: Questions identified

    Where the specification is silent or ambiguous, Gedelec raises a technical question instead of choosing an answer. The question stays open and visible until the engineer resolves it.

    What is the prospective fault level at the incoming supply? (assumed 10 kA for the sample)

  3. Step 3: Calculations completed

    Versioned, unit-tested modules calculate the loads, currents and preliminary sizing from the confirmed design. Interface and connectivity checks run over the result and report anything that needs an engineer to look at it, at the severity the check itself carries.

    No errors, no warnings and 12 notices raised for review

  4. Step 4: Cable schedule

    Each connection becomes a scheduled cable with its service, its ends and its preliminary size, exportable as CSV for your own document control.

    4 cables scheduled

  5. Step 5: Panel arrangements

    General arrangements are drawn from the same model the schedules came from, so the drawings and the tables cannot disagree. Each panel is laid out with its components positioned and dimensioned.

    2 panel arrangements drawn

  6. Step 6: Bill of materials

    Candidate equipment is assembled with ratings and quantities, each line tracing back to the part of the design that required it, and priced into an indicative concept estimate.

    5 candidate lines proposed

How it works

From specification to preliminary design, in five stages

Select a stage to see what you do and what happens underneath.

Attach a specification or describe the system in plain engineering language.

Start with whatever you already have. A written specification, a load list, a scope of works, or a few sentences describing what the system has to do. There is no form to complete first and no workflow to choose: Gedelec reads what you give it and infers the likely shape of the project, then asks you to confirm.

Gedelec reads the input and proposes what kind of project it is.

Engineering assurance

Built so that every number can be checked

Gedelec does not approve, certify or issue the design. The responsible engineer reviews and decides under their own organisation's process.

  • Grounded in deterministic engineering

    Every engineering calculation is repeatable. The numbers come from versioned, unit-tested modules that produce the same result from the same inputs, every time. A language model never computes a final engineering number.

  • Traceable where source records are available

    Traceability is shown where source and calculation records are available. You can follow an output to the requirement it came from, the assumptions it rests on and the calculation that produced it.

  • Engineer approval

    Nothing is automatically issued. Outputs stay marked preliminary and not for construction until a competent engineer reviews and accepts them. Acceptance records your decision; it is never Gedelec approval and never transfers responsibility.

  • Assumptions remain visible

    AI structures and proposes. Assumptions are recorded as assumptions and stay visible next to the results that depend on them. Open questions are raised rather than silently resolved, and results may become stale when inputs change.

Available now

Electrical and controls

Control panels, power distribution, load schedules, cables, connectivity, panel and system arrangements, candidate equipment and concept estimates.

Planned

  • Mechanical and Process
  • Building Services
  • Civil and Structural
  • Architecture and Spatial

Additional disciplines will be introduced as governed packs when their methods, interfaces, assurance boundaries and outputs are implemented and tested.
