Electrical Takeoff

Every receptacle, switch, fixture, panel and piece of low-voltage equipment is counted from the electrical plans, and conduit and wire runs are measured by size and type against the one-line diagram and panel schedules — not scaled from a rough building area.

How we take it off

Devices and fixtures are counted room by room off the power and lighting plans and cross-checked against the fixture schedule for type and quantity. Conduit and wire are measured as actual routed runs from panel to device location, factoring vertical drops and home-run lengths, then totaled by conductor size. Panel schedules are reconciled against the one-line diagram to confirm circuit counts match what's shown on plan.

What the second-estimator review is checking

• Wire footage estimated as a multiplier of device count instead of measured runs, which misses long home-runs
• Low-voltage (data, fire alarm, security) scope bid as part of power and lighting when it needs its own count
• Panel and equipment pad-mount requirements not cross-checked against the one-line diagram
• Fixture schedule quantities not reconciled against what's actually shown on the lighting plan
