3Donay

Digital Architectural Project Approval System

Digitalizes the architectural project approval process end to end: the architect uploads the project online, the municipality reviews it remotely, and the citizen is notified by SMS at every step. Paper queues, CD/USB hand-offs and "what happened to my project?" phone calls become history.

Problem → Solution

The five points where your zoning department loses the most time

3Donay was designed around how Turkish zoning actually works in practice; every module answers a real problem from the field.

Physical paperwork ends

DWG, NCZ, GML and PDF files are drag-and-dropped onto a secure cloud infrastructure instead of being hand-delivered on CDs and USB drives.

Process uncertainty disappears

Which stage the project is at, who holds it, what is expected — both the architect and the administration see it live on the same screen.

Phone traffic drops

Automatic SMS and e-mail go out on every status change; "what happened to my project?" calls and visits come to an end.

Revision chaos becomes order

Requested corrections are flagged per file; the architect updates only what is needed with per-file "Replace" or "Add". No version confusion.

Institutional memory is preserved

All review history, notes, file versions and activity logs are archived permanently; the process survives staff turnover.

The process becomes measurable

Approval times, project volume and unit performance reach management as statistics and reports.

End-to-end flow

From upload to land registry, on one platform

UploadThe architect uploads the project as multiple files (DWG, NCZ, GML, PDF).
ReviewThe technical team previews files online and reviews them with notes.
RevisionCorrections are requested per file; the architect updates only the file concerned.
ApprovalThe decision and its rationale are recorded; SMS goes to the architect and citizen.
Registry trackingThe approved project is tracked on the land-registry panel; if returned, it re-enters the revision flow.

Every user sees only the screens and data they are authorised for.

Session timeout

Idle sessions are closed automatically after a warning.

Server hardening

HTTP security headers, rate limiting and schema-based input validation.

Full audit trail
