The Art of Change: Mastering Change Orders in EPC Contracts

Effective change management is the cornerstone of successful EPC (Engineering, Procurement, and Construction) projects. The inevitable changes in scope, specifications, or timelines can stem from various factors, like unforeseen circumstances, evolving project needs, or regulatory shifts. A well-defined change order procedure outlined within the contract is crucial for navigating these changes smoothly.


The contract should explicitly grant the Contractor the right to propose reasonable changes to the program or specifications. This right extends to recovering additional costs associated with approved changes, such as those arising from extensions of time or force majeure events. Clearly stating these rights within the change order procedure helps prevent disputes.


  • Procedures and Documentation: The contract should specify the procedures for submitting, reviewing, and approving change orders. This includes defining notice periods, approval authority, and the required documentation to support each change request. Detailed documentation should outline the scope of changes, cost estimates, and any other relevant information justifying the change.
  • Permits and Approvals: The contract should clarify who is responsible for obtaining any additional permits or approvals required due to the change. This ensures all legal and regulatory requirements are met before implementing the change.
  • Schedule Adjustments: The contract should outline how changes to the schedule or delivery timelines will be communicated and agreed upon by all parties involved. This helps manage expectations and ensures everyone is aligned on the revised timelines.
  • Testing and Validation: Requirements for testing or validating the changed work should be specified, including who is responsible for conducting these tests. This ensures the quality of the modified work meets project standards.
  • Risk and Liability: The allocation of risk and liability associated with the change order should be clearly defined. This includes any warranty or guarantee obligations arising from the changes.

For changes initiated by the Owner, the contract should:

  • Require written agreement in advance before starting work on the change.
  • Limit the scope of changes, typically to a certain percentage of the contract price, to maintain project feasibility.
  • Detail the scope, price, and program for the change, including its effects on the project timeline, performance, warranties, and other contract terms.
  • Specify payment terms and security of payment to ensure the Contractor is compensated for the additional work.
  • Include procedures for documenting and managing these changes, similar to Contractor-initiated changes.
  • Incorporate a “change in law” provision to address regulatory changes affecting the project. This typically allows for adjustments to the contract terms if such changes occur within a specified period before tender.

Both parties should ensure proper documentation of the change order process and that any changes are implemented according to the contract terms. It’s important to consider the impact of changes on the project schedule, budget, and quality, and to have the necessary resources in place to manage and implement these changes effectively. Additionally, the potential impact of changes on third-party agreements or regulatory approvals should be considered, with steps taken to obtain all necessary approvals before implementing any changes.


By incorporating a comprehensive and clear change order procedure into the EPC contract, all parties involved can manage project changes efficiently, minimize disputes, and pave the way for a successful project outcome.
