What to send for an accurate electrical estimate
Short answer
Send the complete tender package: drawings for every discipline, the full specification including Divisions 01, 26, 27 and 28, all addenda, the bid form, and the bid closing date and time, plus any bid depository closing. Missing architectural or mechanical sheets are the most common reason an electrical estimate misses cost.
Drawings
- Electrical: single line diagram, power, lighting and systems plans, schedules (panels, fixtures, equipment), risers and details.
- Architectural: floor plans, reflected ceiling plans, sections and elevations. Ceiling types and heights change labour and fixture mounting.
- Mechanical: equipment schedules and plans. Every motor, unit heater and pump needs a connection.
- Site and civil: site services, site lighting, duct banks and utility connections.
- Door hardware schedule, if there is access control or electrified hardware.
Specifications
- Division 01 general requirements: phasing, working hours, temporary services, closeout.
- Division 26 electrical, 27 communications and 28 electronic safety and security.
- Divisions 21, 22 and 23 where they assign equipment wiring or controls to the electrical trade.
- Owner standards and approved product lists, common for school boards, hospitals and municipalities.
Addenda and bid documents
