What is a necessary condition for the Owner’s obligation to compensate the Designer?

The necessary condition for the Owner’s obligation to compensate the Designer typically revolves around specific requests made by the Owner that fall outside the original scope of work defined in the contract. The request for additional site visits is significant because it implies that the Owner is asking the Designer to provide services beyond what was originally agreed upon, thereby warranting additional compensation.

When the Owner requests extra site visits, it indicates a need for increased design oversight or adjustments based on conditions observed at the site. This request serves as a trigger for the Designer's obligation to perform additional work, which in turn justifies the Owner’s obligation to pay for that work.

In contrast, while requests for design changes can also lead to compensation, they might not be explicitly tied to the contractual agreement regarding site visits and can be more ambiguous in terms of scope. Similarly, completion of the project and the issuance of substantial completion notices generally relate to final payment stages rather than initiating extra compensation for specific additional services.
