Dear experts, how should the version number and design phase be filled in for the as-built drawings in engineering design drawings?

Revision Number: The revision number of a drawing is used to distinguish the different stages of modification for the same drawing. Each time the drawing is modified, the version number should be updated to keep track of the latest status of the drawing. Typically, version numbers are expressed in letters or as a combination of letters and numbers. For example, the initial issuance might be 0 or A, a subsequent modification might be 1 or B, and so on. Design Stage: The Design Stage indicates the stage of the engineering design to which the drawings belong; the content, details, and accuracy of the drawings can vary depending on the stage. The design phase generally includes the following categories: – Conceptual Design – Preliminary Design – Construction Design – As-Built Drawings, or Record Drawings. As-Built Drawings typically represent the actual construction that took place during the project; these drawings should reflect all changes, adjustments, and the actual layout that were implemented during construction. Therefore, when filling out the as-built drawings, the design phase should be marked as “as-built drawing” or “record drawing”, and the version number should reflect the final state of the drawing updates. For the specific methods of filling in the as-built drawings, it is necessary to refer to the requirements outlined in the project contract documents, company standards, or industry regulations. Different projects or organizations may have their own standards and* practices. A common way to denote the version number of as-built drawings and the design stage might be: – Version number: Rev. 01 (if it is the first version of the as-built drawings); subsequent revised versions could be Rev. 02, Rev. 03, and so on. - Design phase: As-Built drawings. In practice, version control and updates of documents must be carried out strictly in accordance with the project requirements and management processes, to ensure that all stakeholders have access to the most up-to-date and accurate drawing information. .

The initial version number of the as-built drawing is 0; the as-built drawings issued after modifications are numbered sequentially as A, B, …. The as-built drawings prepared by the design institute should indicate the completion stage in their design notation (e.g., construction drawing stage or detailed design stage).
