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.
