Navigating Warranties in EPC Contracts: Understanding Exclusivity and Disclaimers

Warranty periods in Engineering, Procurement, and Construction (EPC) contracts are crucial for ensuring the project’s long-term quality and functionality. Let’s delve into two key aspects that clarify the contractor’s responsibilities during this time: exclusive remedies and disclaimer of implied warranties.


An EPC contract may specify exclusive remedies. This means the repair or replacement options provided by the contractor during the warranty period are the only solutions available to the owner for addressing defects. This limits the owner’s legal recourse and emphasizes the importance of a clearly defined warranty clause.


The contract may expressly disclaim all implied warranties offered by law. These implied warranties, like merchantability or fitness for a particular purpose, generally come with product purchases. By disclaiming them, the contract limits the owner’s expectations and ensures they solely rely on the explicit warranties stated in the EPC contract.


Both exclusive remedies and disclaimers of implied warranties can benefit both the owner and contractor by:

  • Owner: Gains clarity on available solutions during the warranty period.
  • Contractor: Understands the extent of their liability.

However, it’s vital to clearly word these clauses to avoid misunderstandings and potential disputes. An EPC contract should strike a balance between protecting the owner’s interests and ensuring the contractor’s obligations are fair and well-defined.


By carefully considering exclusive remedies and disclaimers of implied warranties, parties involved in EPC contracts can establish a clear and fair framework for addressing warranty-related issues. This promotes a successful project outcome with managed expectations on both sides.
