Construction site management on one drawing, with one set of numbers

What does Santix cover on a site?

The menu mirrors the split between field and office: Overview at the top; under Site, drawings, rooms, tasks and notes, revisions; under Project, schedule, contracts, purchasing, budget and documents; and the team at the bottom. Each person sees only the sections their role opens; someone without budget access never sees the budget entry. The app interface is Turkish.

At some steps AI prepares a suggestion, such as matching a room schedule or reading a date from a scanned document; a person always approves it. See AI assistance.

What is on the project overview?

The overview is the first screen of a project, built to show the state of the site in ten seconds.

Tiles open the matching list. On the sample project Ataşehir Blok B (ATB-02) the screen shows 42 % progress with 128 days to go, 23 open items of which 4 are late, and 2 revisions awaiting the site manager; these are sample figures.

How does one issue move from site to payment?

1. The field engineer pins "#14 Banyo seramik derzi eksik" (bathroom tile grout missing) on room Z-03 of the ground floor plan, adds a photo, assigns the tiling subcontractor and sets a due date. Without signal, the record waits on the device.
2. The subcontractor gets a notification, sees only that pin, does the work, adds a photo and marks it ready for checking.
3. The engineer inspects and closes it, or comments and sends it back.
4. The crew marks the finished area on the drawing; tiling progress is computed from the room's net floor area and flows to the linked task and the schedule.
5. At period end the subcontractor's payment is calculated cumulatively, with retention, advance recovery, withholding tax, stamp duty and VAT withholding on separate lines.
6. It goes for approval; depending on the amount the site manager and owner are notified. The person who entered it hears the decision.
7. If the site contradicts the drawing, a revision request starts from the same spot and reaches the architect after the site manager approves.

Who does what in a typical week?

Role pages: site manager, project manager, architect, subcontractor, owner.

What do notifications cover?

Notifications come from the records themselves and go only to the people concerned, as phone push messages and in the in-app list: a new assignment, a pin status change or comment, each revision step, a payment awaiting your approval or a decision on yours, and reminders 30, 14, 7 and 1 day before a document expires or a contract date arrives. The full list is on team and invites.

What happens without a connection?

Screens read from a local database on the device; every entry is saved there first and sent later. The sync indicator shows states such as "offline, 3 pending" or "1 change could not be sent", and the sync screen lists pending records, uploading photos, voice notes and videos, and failures with their reason, with a sync-now button. Conflicting changes to critical fields such as pin status are shown to you instead of silently overwritten. A few actions that need a server decision, such as redeeming an invite, approving a payment or asking for an AI suggestion, require a connection and say so. See the offline field app.

Phone and tablet layouts

On a phone there are four bottom tabs (overview, drawings, tasks and notes, schedule) and a menu for the rest. On a wide tablet such as an iPad in landscape a sidebar lists every section, lists and details sit side by side, the Gantt chart uses the full width and the room data sheet opens in a side panel. Settings offer light, dark or system theme and a field mode with higher contrast, bolder text and larger buttons for use in sunlight and with gloves.

Who sees what?

Santix has eight roles: owner, organisation admin, project manager, site manager, field engineer, architect, subcontractor and viewer. Permissions are enforced in the database, so rows you may not see never reach your device. People join with an 8-character invite code valid for 14 days. The budget is open by default to the owner, project manager and site manager and can be opened to other roles at summary or full level. See roles and permissions.

Why not Excel and WhatsApp?

On a site run from spreadsheets and group chats, photos, drawings, figures and approvals live in four places. In Santix the photo is tied to a point on the drawing, the figure to a budget line and the approval to the record. See the full comparison with Excel and WhatsApp.

What Santix does not do

• It is not accounting or e-invoicing software; it tracks payments but issues no invoices.
• It does not replace the statutory electronic site diary (Şantiye-M).
• It does not edit drawings; changes are made in CAD and Santix takes the new version.
• No timesheets, payroll or warehouse stock.
• No e-signature; the signed PDF is attached afterwards.
• No web version of the field app; the web panel covers organisation, seats and payment only.
