Drawing revision tracking from site to architect, with an approval step

Who does what in a revision request?

A request passes through four hands: the field engineer raises it, the site manager filters it, the architect answers it, the site manager closes it. Each status change notifies the next person and the requester, and a status line says who is holding it.

1. The field engineer sends it to the site manager; status becomes "awaiting site manager".
2. The site manager approves and forwards it to the architect, optionally with a note, or rejects it with a mandatory reason that goes back to the requester.
3. The architect takes it into review and accepts it, optionally with a note and a new sheet version, or rejects it with a mandatory reason.
4. The site manager and field engineers are notified; the site manager shares the answer with the crew and closes the request.

Where can a request be raised?

• From a revision request pin on the drawing; the request is linked to the pin, so the same pin never gets two requests.
• From a room data sheet, with "Sapma bildir" (report a deviation).
• From the revisions screen, choosing a room and sheet.

The form has title, description, room, sheet and due date. A good title follows the app's own example: "Z-04 clear height measured at 2.60 m". Field engineers, site managers and project managers can raise requests.

What are the statuses?

Eight statuses with fixed transitions, enforced in the database as well, so a request cannot skip the site manager or close without an answer.

What does each role see first?

Architects open on "awaiting your review", site managers on "awaiting your approval", everyone else on "my requests"; open, closed and all tabs follow. The request detail links to the room, the pin and the sheet, lists requested value changes and shows a timeline of every step with date, time, person and note.

How does an accepted change reach the room data sheet?

A request can carry value changes: pick a field such as clear height, the current value fills in, and you enter what it should be. After the architect accepts, the request shows "data sheet not yet updated" with an "apply to room data sheet" button. Once applied, the value changes, its source shows as the architect, and quantities derived from it follow: where wall area is computed from perimeter × clear height, wall paint and wall tiling quantities change with the new height. See room data sheets.

What happens to existing pins when a new version arrives?

The architect uploads a new version from the sheet's version list (single-layout file) and selects it when accepting. Versions are numbered R1, R2, R3 with upload date and a "current" label, and old versions are kept. Pins are tied to drawing coordinates, so they appear at the same point on the new version. Overlay mode draws the top version's lines in the accent colour and common lines dark. Pins are covered under drawing markup.

What should a good revision request contain?

• Location, which comes from the pin or room.
• The problem in one measurable sentence: "the door leaf hits the vanity by 8 cm", not "the door does not open".
• Two photos, close and wide, on the linked pin.
• The value change, if a data sheet number should change.
• The fix the site team thinks is buildable, and the date work will stop as the due date.

Example: a bathroom ceiling on Ataşehir Blok B

1. The field engineer finds the suspended ceiling in Z-03 clashing with a duct, drops a revision request pin with two photos and raises a request from it.
2. The site manager forwards it with a note that the duct route will not change.
3. The architect uploads version R4 of A-101 and accepts the request with it; the ceiling level change is applied to the room data sheet.
4. The site manager tells the drylining subcontractor and closes the request.

Months later, the reason the ceiling sits where it does is in one record, with photos, notes and the version.

Why not email and WhatsApp?

By email, the question, the answer and the new drawing live in three places, rejections are explained on the phone, and nobody knows whether the room schedule was updated. In Santix the photos, decisions with mandatory reasons, the architect's note, the new version and the data sheet update sit in one record.

Who can approve and publish?

Only the site manager approves requests and only the architect answers them. New sheet versions can be uploaded by the architect, site manager and project manager. Subcontractors and viewers can read requests but cannot raise, approve or answer them. See the architect role, the site manager role and our revision management guide.

What does it not do?

• It does not edit drawings or list differences between versions; differences are read in the overlay.
• It does not apply accepted changes to the data sheet without a person confirming.
• It does not replace official permit amendments; it records the request and answer within the team.
