How to Create Contract Change Orders

Complete workflow guide for creating change orders in construction project management

Creating change orders allows you to formally document contract modifications for your construction project. Use this process to track scope changes, cost adjustments, and time extensions while maintaining accurate project records.

Before you start:

  • Ensure you have an active contract in your project
  • Have change order details and supporting documents ready
  • Verify your contract has a completion date added (required for EOT change orders)

Steps

Access the add change order form

  1. Navigate to your project and click Cost Module in the left sidebar
  2. Choose one of these options to create a change order:
    • Click the + Add button in the top right corner of the Overall Cost page
    • Select a specific budget, click the Actions button, and choose + Add Contract from the dropdown
    • Go to Change Orders Register and click + Add Change Order in the top left corner

Complete change order details

  1. Enter a descriptive title for your change order
  2. Select the Varying Contract from the dropdown menu
  3. Choose the appropriate Change Order Category that describes your type of change
  4. Select the change order Status:
    Status Meaning Financial Impact
    Forecast Early estimate or projection; used for planning only. Uncommitted Cost in FFC, doesn't appear in Payments
    Pending Awaiting review, input, or further documentation. Uncommitted Cost in FFC, doesn't appear in Payments
    In Principle Tentatively approved but not yet finalized or signed off. Committed Cost in FFC, appears in Payments
    Approved Officially approved and added to the contract. Committed Cost in FFC, appears in Payments
    Rejected Reviewed and declined; not progressing further. Doesn't impact FFC, doesn't appear in Payments
    Withdrawn Manually removed from the process (e.g., withdrawn by submitter). Doesn't impact FFC, doesn't appear in Payments

Add change order description and background

Only the first few lines of the description appear in approval letters right now. 

  1. Click the Description tab below the Change Order basic details section
  2. Add your change order description including background, scope, and justification
  3. Write clearly as this text will appear in Change Order Approval letters

Configure Time Impact

  1. Navigate to the Time Impact section
  2. Enter Days Claimed - the number of weekdays being requested for extension
  3. Enter Days Approved - the number of weekdays actually approved
  4. Manually adjust the Revised Completion Date if needed
  5. Add relevant comments in the Comments field
  6. Use Internal Only Notes for information visible only to project users

Mastt automatically calculates the revised completion date using weekdays only (Monday to Friday).

Complete Additional Fields

  1. Click on Additional Fields to add optional reference numbers or identifiers
  2. Enter any tracking numbers important to your change order management
Information entered here will appear in Change Order Approval Letters.

Enter financial details

  1. Review the contract line items displayed in the table
  2. For affected line items, enter the amount in the Change Order Amount column
  3. Notice the system automatically calculates:
    • Current contract value
    • Contract post change order (showing new total)
  4. If working with estimates, use the Preliminary Amount field for estimated values

Add supporting information

  1. Add notes in the Notes section to describe why this change is needed
  2. Upload supporting documents in the Attachment area

Internal Only notes are visible to project users only. These notes won't appear in change order letters - use for internal tracking and communication.

Finalize change order

  1. Review all information to verify calculations are correct
  2. Click the Add (blue button, bottom right) to save the change order
  3. The change order now appears in your change order list with the selected status

Pro tips

  • Use clear, descriptive titles for easy identification and tracking of change orders
  • Document change orders thoroughly with detailed notes
  • Update status as change orders progress through approval
  • Attach supporting documents for better record keeping
  • Regularly review change order impact on project costs and timeline
