The final status a drawing reaches once the design team, and often the client or approving authority, has signed off on it - work can now legally start on site from that revision. AFC is the last stop in a drawing's CDE status lifecycle (Work in Progress, Shared, Published/AFC), and any change after this point requires a formal revision, not a quiet edit.

Confusingly, some firms use AFC and IFC Drawings almost interchangeably; others draw a sharper line - IFC marks the moment drawings are issued to the site team, while AFC confirms they have been formally approved, which may happen slightly earlier or later depending on the project's issue tracking workflow. Either way, once a drawing set is superseded by a newer AFC revision, the old one should be clearly marked void to avoid the classic, and expensive, mistake of a contractor building from an outdated sheet.
