Keeping Control: Safeguarding Your Rights with Owner-Initiated Changes in EPC Contracts

EPC contracts offer a structured approach to project delivery, but what happens when the owner needs to adjust the project scope? Understanding the specific conditions for owner-initiated changes empowers you to manage the process effectively and minimize potential disruptions.


Early Agreement is Crucial: Any owner-initiated changes to the project scope, price, or program must be agreed upon in writing and documented before any work commences. This ensures clarity and avoids misunderstandings.


Percentage Thresholds: Consider setting a limit on the cumulative value of owner-initiated changes. A typical range might be ± 15% of the original contract price. This helps manage project complexity and cost overruns.


  • Detailed Change Orders: Change orders for owner-initiated modifications should clearly specify:
    • The exact nature and scope of the changes.
    • The agreed-upon price for implementing the changes.
    • Any revisions to the project schedule or program necessitated by the changes.
  • Impact Assessment: The change order should outline how the changes will affect the project program,performance, warranties, and other relevant contract terms.

  • Payment Terms: Clearly define the payment terms for owner-initiated changes. This ensures the contractor receives fair compensation for the additional work.
  • Security of Payment: Consider including provisions that guarantee payment for the approved changes, protecting the contractor’s cash flow.

  • Procedures and Notice Periods: Establish clear procedures and timelines for submitting, reviewing, and approving owner-initiated change orders.
  • Documentation Requirements: Specify the documentation required to support owner-initiated changes. This might include technical specifications, cost breakdowns, and justifications for the proposed modifications.

Change in Law Provision: Include a provision that allows for adjustments due to changes in law or regulations.This typically requires a 30-day notice before the tender for the change order is submitted.


Beyond the contract itself, remember these best practices for managing owner-initiated changes:

  • Meticulous Documentation: Ensure all change orders are properly documented and filed for future reference.
  • Impact Assessment: Carefully consider how each change will affect the project schedule, budget, and quality.Allocate necessary resources to manage and implement the changes effectively.
  • Third-Party Considerations: Evaluate the potential impact of changes on any third-party agreements or regulatory approvals. Proactively obtain any necessary approvals before implementing the changes.

By incorporating these measures into your EPC contract, you can establish a clear and manageable process for owner-initiated changes, fostering a more predictable and successful project lifecycle.


Remember: Consulting with a construction lawyer is highly recommended. They can ensure your EPC contract effectively addresses owner-initiated changes and protects your interests throughout the project.
