As-built drawings do not need the seal of the supervisor. Where the project is constructed according to the construction drawing, the completion drawing preparation unit shall affix the completion stamp in the blank space near the drawing mark of the construction drawing (clean blueprint), and the relevant personnel shall personally sign it.

For general drawing changes, the preparation unit can directly redraw the construction drawing according to the design change basis, indicate the change and modification basis, and affix the completion stamp and sign it.

If the major changes or changed parts found in the structural form, process, layout and project cannot be redrawn on the original construction drawing, the completion drawing shall be redrawn and stamped with the completion stamp. The redrawn drawing must have the drawing name and drawing number, and the drawing number can be numbered according to the original drawing.
