What information must be included in the drawing identification header?

• A. Title, number, date, revision numbers and dates
• B. Title only
• C. Number and date
• D. Revision numbers only

Answer: (A)

Drawing headers must clearly identify the drawing and show its current revision so everyone uses the same, up-to-date information. The header should include the title, the drawing number, the date of issue, and all revision numbers with their dates. The title tells you what the drawing shows; the number provides a unique project-wide identifier; the date indicates when this issue was released; and the revision numbers with dates record every change and when that change was approved. Together, these elements ensure traceability, keep QA and field crews aligned on the correct version, and prevent mixing outdated information into construction activities. If any part is missing, essential context is lost: a header with only the title lacks a unique ID and revision history; only the number and date omit what changed and when; and only revision numbers omit the drawing’s identity and baseline date.
