Material that traces back to the drawing.
From run to material
In VoltDrop, material is derived from the electrical relationships rather than counted independently of them. A feeder run carries its conductors and raceway; a branch circuit carries the wire, raceway, boxes, and devices it serves.
That means a change to the feeder — a breaker revised in an addendum, a route adjusted by the contractor — updates the material that depends on it, instead of leaving two numbers that disagree.
Conductors
Derived from the run: size, material, insulation, and length including the pull allowance you set.
Raceway
Type and trade size sized against conduit fill, with the fill calculation available to review.
Devices and boxes
Counted from the plans and associated with the circuit that feeds them.
Equipment
Panels, transformers, disconnects, and switchgear read from the one-line and schedules.
Why provenance matters at buyout
When a quantity is questioned during buyout, the useful answer is a sheet number. VoltDrop keeps that link on the line item, so a material quantity can be checked against the document that produced it rather than re-derived from scratch.
Quantities that could not be confirmed stay marked as open. A takeoff that is honest about its own uncertainty is more useful than one that is uniformly confident and occasionally wrong.
