Commercial Electrical Estimating Services
Tribuild takes off electrical by system: service and distribution, feeders, branch circuits, lighting, and devices, with conduit and wire measured by linear foot and every fixture, gear item, and connection counted, so your bid is built on the drawings, not on assemblies.
Electrical bids come apart when conduit and wire are assumed by assembly instead of measured. Tribuild takes off electrical by system, service and distribution from the one-line, feeders from the schedule, branch circuits by home run, and measures conduit and wire by linear foot with fittings and terminations.
Fixtures, devices, gear, and equipment connections are counted by type from the schedules and plans, fire alarm and low voltage are excluded as separate scopes, and every deliverable ships with documented assumptions your team can price and defend.
What we estimate for electrical
Service and distribution
Service entrance and distribution counted by unit from the one-line diagram.
Switchgear and transformers
Switchgear, switchboards, and transformers counted by unit and rating.
Panels
Panelboards counted by unit with size and circuit count.
Feeders
Feeder conduit and conductors by linear foot and size from the feeder schedule.
Branch circuits
Branch conduit and wire by home run and device, measured by linear foot.
Conduit
Conduit by type and size, measured by linear foot with fittings.
Wire and cable
Conductors by size and length with terminations.
Lighting
Interior and exterior fixtures counted by type from the lighting plan and schedule.
Lighting controls
Switches, sensors, dimming, and lighting-control devices counted by type.
Devices
Receptacles, switches, and cover plates counted by type.
Grounding
Grounding electrodes, conductors, and bonding by unit and linear foot.
Equipment connections
Motor and equipment connections counted from the mechanical/equipment schedules.
Generators and UPS

Frequently asked questions
Power, lighting, and site plans, the one-line diagram, panel and feeder schedules, the lighting/fixture schedule, and specifications. Mechanical schedules help us count equipment connections.
Yes, fixtures, receptacles, switches, and gear are counted by type from the schedules and plans, not lumped into an assembly.
No, fire alarm and low-voltage/communications are separate scopes and are not included. This page covers power, lighting, and distribution.
Measured by linear foot and size with fittings and terminations, so runs are quantified from the drawings.
