SCOPE

Understand contractual electrical obligations.

RUNS

Map feeders, circuits, and source-to-load relationships.

MATERIAL

Turn project information into usable takeoff data.

RISK

Surface conflicts, assumptions, and missing information.

THE CORE IDEA

A receptacle isn’t just a symbol.

Most takeoff software counts objects. VoltDrop is being built to understand how the electrical job connects — because the cost, the labor, and the risk all live in the relationships, not the count.

PRODUCT WALKTHROUGH

From contract set to buildable electrical intelligence.

A worked example on a sample project. Every number traces back to the document it came from, and everything the engine is unsure about is flagged for contractor review rather than quietly assumed.

This walkthrough uses sample project data to show how the pieces connect. Full drawing intelligence, automated scope analysis, and routing are in active development — see the capability list below for current status.

RUN INTELLIGENCE

A run is a project object, not a line of text.

Feeders and homeruns are where electrical scope becomes buildable work. VoltDrop treats each one as a structured record with a source, a destination, an electrical system, and the material it takes to install.

Example record · Sample project data

  • In DevelopmentRun generation · Active development
  • Source to destination

    A run exists because two pieces of equipment are related. MDP-1 feeds LP-2 — that relationship is the record, not a line item on a sheet.

  • Stable identifiers

    FDR-014 stays FDR-014 through estimating, coordination, prefab, and installation. The same object, referenced by the same name, at every stage.

  • Editable route length

    Estimated lengths are a starting point with the assumptions shown. The contractor adjusts them; the run carries the revision.

  • Carries downstream

    Conductors, raceway, fittings, and labor all hang off the run — so a change to the feeder updates everything that depends on it.

VOLTAIRE · 06

Meet Voltaire. Ask the project.

VoltDrop's electrical intelligence assistant. Voltaire reads the set the way an experienced estimator does — across disciplines, against the specification, and with an eye for what doesn't line up.

Electrical Intelligence AssistantIn Development

Electrical projects rarely suffer from a lack of information.

They suffer because that information is scattered across drawings, specifications, schedules, details, revisions, notes, and multiple disciplines.

Voltaire was created to interrogate that information.

  • Ask about a feeder.
  • Ask what's missing from the scope.
  • Ask where a requirement came from.
  • Ask which drawing changed.
  • Ask why a run was flagged.

Voltaire shouldn’t just give you an answer.

It should show you where that answer came from.

Why Voltaire?

The name begins with the obvious connection to Volt, but the reference goes further.

Voltaire was known for questioning assumptions, argument, inquiry, and reason.

VoltDrop’s Voltaire applies that same mentality to construction documents: compare the information, identify contradictions, challenge assumptions, and surface the items worth another look.

Thankfully, ours knows significantly more about conduit.

Every answer traceable.

Every calculation reviewable.

PLATFORM CAPABILITIES

Eight capabilities. One connected project model.

Each capability is labelled with where it actually stands today. We would rather tell you what is still being built than have you find out during a bid.

  • 01 · INTELLIGENCE

    In Development

    Understand the electrical scope.

    Review electrical drawings together with specifications, schedules, addenda, architectural information, mechanical equipment requirements, and supporting contract documents. Help identify electrical obligations that can otherwise be scattered across the set.

  • 02 · TAKEOFF

    In Development

    Quantify what's actually there.

    Identify electrical equipment, devices, feeders, raceways, conductors, and relevant assemblies. Connect quantities back to their drawing and document sources.

  • 03 · RUNS

    In Development

    Turn electrical systems into organized runs.

    Create source-to-destination relationships for feeders and circuits. Organize runs using stable identifiers that can follow the project through estimating, coordination, prefab, and installation.

  • 04 · ROUTING

    Planned

    Plan how the work gets there.

    Assist with proposed feeder pathways and homeruns. Show estimated route lengths and editable routing information.

    Routing recommendations require contractor review and may depend on available architectural and BIM information.

  • 05 · ENGINEERING

    Early Access

    Verify the math.

    Deterministic calculation engines handle the critical electrical math. AI assists with interpretation rather than inventing engineering calculations.

    • Voltage drop
    • Conductor sizing
    • Conduit fill
    • Grounding
    • Feeder sizing
    • Electrical loads
    • Other configurable rules
  • 06 · VOLTAIRE

    In Development

    Ask the project.

    Ask natural-language questions across project information. Every important response references the drawing, specification, schedule, or source used to produce the answer.

  • 07 · RISK

    In Development

    Find expensive questions early.

    Surface the items that turn into change orders and RFIs when they go unnoticed until the job is underway.

    • Scope ambiguity
    • Conflicting documents
    • Missing information
    • Questionable assumptions
    • Unresolved responsibility
    • Potential RFIs
    • Revision impacts
  • 08 · HANDOFF

    Planned

    Take the intelligence downstream.

    Create structured information built to support the teams that pick the job up after preconstruction.

    • Estimating
    • BIM / VDC
    • Prefabrication
    • Procurement
    • Project management
    • Field installation

POSITIONING

Takeoff software counts it. VoltDrop understands it.

Each of these categories does something useful, and most electrical contractors use several of them. What none of them does is hold the electrical system together as one connected model.

  • Generic AIRecognizes information.
  • Takeoff SoftwareCounts and measures it.
  • Estimating SoftwarePrices it.
  • BIM SoftwareModels it.

ELECTRICAL ENGINEERING ENGINE · 05

Intelligence backed by electrical math.

VoltDrop began with a simple idea: electrical calculations should be fast, structured, repeatable, and connected to the rest of the job. What started with voltage drop becomes part of a broader intelligence system connecting electrical scope, runs, materials, and calculations.

Deterministic calculation engines perform the critical electrical math — the formula, the code references, and the assumptions are all shown. AI assists with interpreting documents, not with inventing engineering results.

TRUST

Every answer traceable. Every calculation reviewable.

Electrical contractors carry the liability for what gets installed. Software that asks for blind trust is not useful to them — so VoltDrop is built to show its work.

  • Show the source

    Derived information carries the drawing, sheet, or specification section it came from. If we cannot point at a source, the item is flagged rather than asserted.

  • Deterministic where it matters

    Critical electrical math runs through calculation engines with published methods and references. AI is used to read and reconcile documents, not to invent engineering results.

  • Show the disagreement

    When two documents conflict, both are shown side by side. The contractor decides which one governs — the software does not quietly pick one.

  • Review status is explicit

    Nothing is silently accepted. Items move from open to reviewed to approved by a person, and the record shows who and when.

Travels with every derived value

  • Source drawing
  • Specification reference
  • Sheet reference
  • Confidence level

BUILT FOR

The whole preconstruction team.

Electrical preconstruction is not one job. VoltDrop is designed around what each role actually needs out of the contract set.

  • Estimators

    Bid with the scope actually understood.

    Get the electrical obligations out of the set and into a structure you can price — with the conflicts and missing information flagged before the number goes out the door.

    • Scope clarity
    • Traceable quantities
    • Fewer surprises after award
  • Preconstruction

    Resolve the expensive questions early.

    Review drawings, specifications, schedules, and addenda together instead of one discipline at a time. Surface the items worth an RFI while there is still time to ask.

    • Document reconciliation
    • Revision impact
    • RFI candidates
  • BIM / VDC

    Start coordination from structured input.

    Feeders and homeruns arrive as records with sources, lengths, and stable identifiers — not as a set of sheets somebody still has to interpret.

    • Structured runs
    • Stable identifiers
    • Source references
  • Project Managers

    Know what changed and where it came from.

    Revisions and addenda get compared against what was originally bid, so the delta is visible rather than discovered in the field.

    • Revision tracking
    • Scope deltas
    • Documented assumptions
  • Electrical Contractors

    One connected picture of the electrical job.

    Scope, systems, runs, material, and calculations held together as a single project model that carries from the bid through to installation.
