What work appears under Division 26?
The project manual controls the detailed section list. Estimators commonly use the division as the main index for electrical scope, then reconcile it with every related document.
| Use | Action | Limit |
|---|---|---|
| Specification index | Find electrical sections | Does not replace drawings |
| Work breakdown | Group estimate packages | Does not define every interface |
| Vendor enquiries | Reference applicable sections | Needs drawings and schedules too |

What should be cross-checked outside Division 26?
Review general requirements, earthwork, concrete, communications, controls, fire protection, mechanical and commissioning information when the electrical scope interfaces with them. Use the tender's own section numbers and titles.
Common questions
What else should the bid team know?
Is Division 26 a code?
No. It is an information-classification division. Codes and standards are separate project requirements.
Does Division 26 include low-voltage systems?
Some electrical work may appear there, but the project manual may place communications, safety and controls in other divisions.
Can a takeoff use Division 26 alone?
No. Drawings, schedules, bid forms and other specifications can add or qualify scope.
