Which document item records when the bridge design work was completed and serves as a reference for revisions?

• A. Date of Design
• B. Responsible Engineer
• C. Bridge Classification
• D. Load Condition

Answer: (A)

Recording when the design work was completed is the baseline for revisions. This date marks the moment the design is considered finished and serves as a reference point for updating or changing drawings and specifications later. It helps with version control, traceability, and QA, so engineers know which edition of the design is in use and what revisions were made afterward.

Other items don’t provide that timing and revision reference: the responsible engineer indicates who did the work, not when it was finished; bridge classification describes the type or category of the bridge; and load condition relates to the loads the design must withstand, not the completion date or revision history.
