Which division range is reserved for expansion?

• A. Division 15-19
• B. Division 20
• C. Division 24
• D. Division 26

Answer: (A)

Divisions set aside for expansion are a dedicated home for future work, keeping any added scope organized without changing the base project documents. In this numbering scheme, the range that covers major building systems is reserved for expansion, which is why this range is used for future additions, upgrades, or extensions. Putting expansion here makes it easier to add new work later—like extra mechanical, electrical, or related systems—without altering the sections that describe the current scope. The other ranges aren’t designated for that purpose, so they don’t provide the same convenient placeholder for future work.
