How do I set up a plan review platform for document uploads, version control, and routed approvals?

Here’s a practical way to set up a plan review platform for document uploads, version control, and routed approvals.

1) Define the workflow first

Before choosing software, map the process:

• Upload: who can submit plans?
• Versioning: how are revisions named and stored?
• Review routing: who approves what, and in what order?
• Status tracking: draft, under review, approved, rejected, revised
• Notifications: who gets alerted on upload, comment, approval, rejection
• Audit trail: who changed what and when

A simple workflow might be:

1. User uploads plan set
2. System creates version v1
3. Review tasks route to assigned reviewers
4. Reviewers comment/approve/reject
5. If changes are needed, uploader submits v2
6. Final approval locks the version and archives the record

2) Choose the platform approach

You generally have 3 options:

A. Low-code / no-code platform

Good if you want faster setup with less custom development.

Examples:

• Microsoft SharePoint + Power Automate
• Airtable + Make/Zapier
• Monday.com / Smartsheet + workflow automation
• DocuWare / M-Files / Box with approval workflows

Best for:

• Small to mid-size teams
• Standard approval flows
• Basic document management

B. Custom web app

Best if you need:

• Complex routing rules
• Strict version control
• Custom annotations or markup
• Integration with BIM/CAD/project systems
• Regulatory/audit requirements

Typical stack:

• Frontend: React / Vue
• Backend: Node.js / Python / .NET
• Storage: S3 / Azure Blob / Google Cloud Storage
• Database: Postgres
• Auth: SSO / OAuth / SAML
• Workflow engine: Camunda, Temporal, or custom state machine

C. Specialized construction/engineering plan review software

Best for plan sets, permits, and markups.

Examples:

• Procore
• Autodesk Construction Cloud
• Bluebeam Revu / Bluebeam Cloud
• e-Builder
• Accela / permitting systems

These often already support:

• Plan sheets
• Markups/comments
• Review cycles
• Role-based routing

3) Core features to implement

Document upload

• Allow PDF, DWG, DOCX, images, and other supported formats
• Enforce file size limits and file type validation
• Store metadata:
  • project ID
  • document type
  • version
  • submitted by
  • date submitted
  • status

Version control

Use a clear versioning scheme:

• Major/minor versions: A, B, C or v1, v2
• Freeze approved versions so they can’t be edited
• Keep a complete version history
• Compare versions if possible
• Link comments/decisions to a specific version

Important rule:

• Never overwrite files. Always create a new version.

Routed approvals

Build a workflow engine that can:

• Route by project type, document type, department, or discipline
• Support sequential or parallel approval
• Send reminders and escalations
• Record approval timestamps and comments
• Require sign-off from all required reviewers before final approval

Common routing patterns:

• Sequential: Reviewer A → Reviewer B → Reviewer C
• Parallel: all reviewers review at once
• Conditional: route only if certain fields or project attributes match
• Escalation: if no response in X days, notify manager

4) Design the data model

At minimum, track these objects:

• Users
• Roles
• Projects
• Documents
• Document Versions
• Reviews / Review Tasks
• Comments / Markups
• Approval Decisions
• Audit Logs

Example relationships:

• One project has many documents
• One document has many versions
• One version has many review tasks
• One review task belongs to one reviewer
• One audit log records one action by one user

5) Permissions and roles

Set role-based access control from the start.

Typical roles:

• Uploader / Submitter
• Reviewer
• Approver
• Project Admin
• System Admin
• Viewer / Read-only

Rules to consider:

• Uploaders can’t approve their own submissions
• Reviewers only see assigned items
• Approvers can finalize decisions
• Admins manage routing templates and permissions

6) Notifications and reminders

Add automation for:

• Submission received
• Review assigned
• Reminder due soon
• Approval completed
• Rejection with comments
• Resubmission required

Channels:

• Email
• In-app notifications
• Slack / Teams
• SMS, if necessary

7) Audit and compliance

For a review platform, auditability is critical.

Log:

• uploads
• downloads
• comments
• approvals/rejections
• version changes
• routing changes
• permission changes

Also consider:

• immutable storage for approved documents
• retention policies
• e-signature support if needed
• timestamps with timezone consistency
• exportable audit reports

8) User interface essentials

A good UI should include:

• Project dashboard
• Document list with status and version
• Upload form
• Review queue
• Document viewer with markup/comments
• Approval history timeline
• Filters for status, discipline, due date, reviewer
• Search by project/document/version

9) Suggested implementation blueprint

If you’re building it yourself:

Backend

• Auth and roles
• Upload API
• Version creation service
• Workflow routing service
• Notification service
• Audit log service

Storage

• Store files in object storage
• Store metadata in relational DB
• Generate previews/thumbnails if needed

Workflow

• On upload, create document version
• Assign review tasks based on rules
• Update status as tasks complete
• On final approval, lock version and archive

Frontend

• Submit new document
• View versions and comments
• Review/approve/reject
• See approval status and history

10) Start with an MVP

A solid minimum viable product would include:

• Login and role-based access
• File upload
• Document version history
• Simple approval workflow
• Reviewer comments
• Email notifications
• Audit log

Then add:

• markup tools
• parallel approvals
• templates
• integrations
• reporting
• mobile support

11) Recommended setup for different needs

Small team

Use:

• SharePoint or Box
• Power Automate
• Microsoft Teams notifications

Mid-size operations

Use:

• Airtable/Smartsheet or a document management system
• Approval automations
• SSO and audit logs

Enterprise / construction / permitting

Use:

• Autodesk Construction Cloud / Procore / Accela
• Or a custom platform with workflow engine and strict controls
