The Seal of Authority
The construction industry's dedicated drawing management and approval intelligence platform — the authoritative record of every drawing that has passed through review, been approved, and been signed.
The Problem
On every active project, hundreds of drawings move constantly between architects, consultants, contractors, and owners. Each one passes through review, revision, and approval cycles that determine whether the work is buildable — and legally defensible.
Yet the industry still tracks these cycles in Excel registers, email threads, and shared folders. Approvals get lost. Revisions get missed. Nobody can tell, at a glance, which drawings are holding up the site, which ones need signatures, or which version is actually the approved one.
The result: delays, rework, disputes, and a costly audit trail that nobody trusts.
The Solution
01
Live synchronisation with Autodesk Construction Cloud. Every drawing, revision, and metadata field stays in lock-step with your ACC environment — no duplicate uploads, no version drift.
02
Zoho Sign workflow embedded directly in the approval chain. A drawing moves from submission to signed record without ever leaving Signum — with a full cryptographic audit trail.
03
Approved, in review, submitted, overdue — across CAT I to CAT IV. Leadership sees project health at a glance; project engineers see what to do next.
04
Viewer, Editor, Admin — granular permissions enforced at the drawing level. SignalR-powered live updates mean everyone is always looking at the same truth.
05
Every state change is logged, hashed, and exportable. When the auditor, the architect, or the court asks “who approved this?” — you have the answer.
06
One-click Excel export of the full drawing register state — for handover documentation, financial close-out, or legacy record-keeping.
How It Works
STAGE 01
Link your Autodesk Construction Cloud project. Drawings and metadata flow into Signum automatically.
STAGE 02
Set review categories, approval chains, and role permissions for your project's specific workflow.
STAGE 03
Track every drawing through submission, review, and revision cycles with live status visibility.
STAGE 04
Final sign-off via Zoho Sign produces a legally valid, tamper-evident approved record.
Built On
Signum is engineered on Microsoft Azure with C# on the backend and SignalR for real-time updates. Drawings sync bidirectionally with Autodesk Construction Cloud via their Platform Services API. Signatures flow through Zoho Sign's cryptographic signing pipeline. Every service is deployed to Azure's Central India region for data residency and low latency.
No single-vendor lock-in on your project records — everything you put in comes out cleanly in standard formats, every time.
