About This Automation A change and variation register tracks scope changes on a construction project from initial request through pricing, approval, and budget update. Manual tracking across spreadsheets and email makes it easy to lose track of pending approvals and leaves budgets out of date.
The automated version logs each request, drafts variation orders once pricing arrives, and routes approvals without manual chasing. Budgets, site teams, and project files stay current as soon as a client signs off.
Key features:
Captures incoming variation requests and creates register entries automatically Checks each request against contract scope before it moves forward Assembles the formal variation order once subcontractor pricing is received Routes drafts for internal sign-off and client approval in sequence Chases unsigned approvals without manual follow-up Updates the budget forecast and notifies the site team once approved Top friction points when done manually The issues teams report most often with this process
# Friction point Companies Report This 1 Unsigned approvals pile up
Multiple open variations require manual chasing at the same time.
80% 2 Drafting takes too long
Assembling the formal variation order manually is slow and repetitive.
67% 3 Register falls out of date
Entries are not updated the same day pricing or approval changes.
53% 4 Budget lags real position
Approved variations are not reflected in the cost forecast right away.
40% 5 Site team told late
Approved changes reach the site team after work should have started.

1. Variation Request Received trigger
Automation triggers the moment a scope change is reported by email or logged as a RFI.
2. Log Request With Intake
The intake reads the request, checks it against contract scope, and opens a new register entry.
3. Update Variation Register
The new entry, including status and scope summary, is written directly into the master register.
4. Draft Variation Order
Once a subcontractor cost estimate is received, the drafting produces the variation order with cost and schedule impact.
5. Send For Approval
The approval routes the draft for internal sign-off then sends it to the client for signature.
6. Send Approval Reminder
If the client has not responded within the set window, an automatic reminder goes out until it is signed.
7. Notify Site Team
Once approved, the site supervisor is notified so work on the change can proceed.
8. File Signed Variation Order
The final signed document is confirmed and filed against the project record.
