Which fields make a takeoff reviewable?
Use the project work breakdown and Division 26 structure as a starting point, then adapt it to the actual drawings and scope.
| Field | Example | Review |
|---|---|---|
| System | Emergency power | Scope match |
| Item | Feeder or termination | Tag source |
| Quantity | Measured value | Drawing reference |
| Unit | Length, each or set | Consistent basis |
| Status | Measured or allowance | Owner assigned |
How should plans and schedules be reconciled?
Use equipment tags and feeder references as the bridge between plans, single lines, elevations and schedules. Flag a mismatch instead of choosing the larger or smaller quantity silently.
- Drawing and revision
- Equipment tag
- Measured or allowed quantity
- Supplier or trade boundary
- Open interface
What should the takeoff reviewer look for?
Review unreferenced rows, duplicate tags, missing terminations, unmeasured interfaces and quantities changed by addenda. The review does not select design values.
Common questions
What else should the bid team know?
What should a electrical bid takeoff include?
It should show system, item, quantity, unit, source, status, trade boundary and open issue.
Who reviews a electrical bid takeoff?
The estimator or quantity reviewer checks the takeoff, while the responsible engineer confirms design inputs.
Does this page create project quantities?
No. Use the issued drawings, schedules and specifications. The estimator reviews and approves the project basis.
