Why Drawing Revisions Belong in a System, Not a Filename
Every practice has the folder. Here is what goes wrong when revision history lives in filenames, and what it takes to prove which drawing actually went to site.
Open any architecture practice's project folder and you will find them: Plan_rev2.dwg, Plan_rev2a.dwg, Plan_FINAL.dwg, Plan_FINAL_updated.dwg. Everyone jokes about it. Nobody fixes it. And then a contractor builds from the wrong sheet, and the joke becomes a variation claim.
The filename is not a version history
A filename records what someone typed at the moment they saved. It does not record who changed what, when it changed, or which version was issued to whom. When a question arrives six months later — was the revised setting-out ever sent to the structural engineer? — a filename cannot answer it. Somebody goes hunting through sent mail.
What proper revision control gives you
- Every revision retained, so saving over a drawing does not destroy the previous one
- The ability to restore any earlier version, not just the last one
- A visible flag on the file list showing which drawings carry history
- A record of who opened or downloaded a sheet, and when
The consultant problem
Drawings do not stay in the studio. Structural, MEP, contractors, the client — each needs some of the project and none needs all of it. The usual answer is a shared link to the whole folder, which quietly stays live long after the package is issued.
Time-boxed guest access solves this properly: a consultant is given the specific folder they need, with an expiry date you set. Every view is recorded, and access can be pulled at any moment. Nobody has to remember to revoke it, because it closes itself.
Hours are the other thing filenames cannot hold
Practices lose fees the same way they lose drawings — informally. Studio hours go unrecorded, so the fee proposal for the next project is guesswork built on the last one's guesswork. When hours and disbursements are logged against the project as the work happens, the invoice is raised from that tracked work, and the number reflects what was actually done.
What to change first
- Stop encoding revisions in filenames — let the system hold the history
- Give consultants folder access with an expiry, not a standing link
- Put issue and sign-off through an approval step so there is a record of what went out
- Log hours against the project from day one, not at invoicing time
SyncOffice keeps every drawing revision, gives consultants access that expires on your date, and carries project hours into the fee invoice. See how it works for architecture firms →
