A Document Revision Numbering System is an engineering and design document control system to ensure that the project members are informed any design changes and the latest information. The common revision system is using a numeric (1, 2, 3 …) and/or alphabetic sequence (A, B, C …). After the initial issue of a document and followed by changes or further design developments, all revisions will be assigned the next higher alphabetic or numeric character. (e.g., Issued for Internal Review: A1, A2 …; Issued for Client Review: B1, B2 …; Issued for FEED: 0A, 0B …; Issued for Design and Construction: 01, 02 …).
