A modification is considered outside the scope of an existing contract if it introduces what type of difference?

A modification introduces a difference that is considered outside the scope of an existing contract when it involves a material change in work or costs. Such changes can significantly affect the contract's original intent, cost structure, or the nature of the work being performed. Material differences can include alterations that affect the fundamental aspects of what was initially agreed upon, potentially impacting the performance or delivery of the contract.

When modifications create substantial differences in the work required or significantly affect costs, they may require a new procurement process. This is because they change the original agreement's essential terms to such an extent that the original solicitation would not have led to the same contract award. Understanding this principle is fundamental for contract management and helps ensure compliance with procurement laws and regulations.

In contrast, variations that are minor in terms or that only adjust the dollar amount without changing the underlying work or nature of the tasks typically do not exceed the contract's original scope. A change in personnel, such as a project manager, does not inherently change the contract's scope either, as it does not alter the terms or requirements of the work to be executed.
