Document control looks like admin, until the moment someone needs proof. Then the question is always the same: who got this, who changed it, who signed it, and can you show it. On most projects the answer is a search through shared drives, zip files and sent mail, reconstructed under contractual pressure months after the fact.
In Hub it's a byproduct of doing the work: every delivery, comment, markup and sign-off is recorded against the document and the revision it concerned, aligned to ISO 19650. Handover, an audit or a dispute becomes a lookup, not an investigation. Two of the moments where that shows up:
→ delivery3 emails → 1 record
A milestone that went out as three zips in three inboxes becomes one collection, one link, and a record of who received what. When the client asks three months later whether a spec was in Friday's issue, it's a check, not a search through sent mail.
→ Published state“Is this the latest?” → the one to build from
No shared-drive hunt, no stale local copy. Open the Published folder and the revision on screen is the one approved to build from, version state visible, so no crew pours concrete off a superseded drawing.
