32 CFR 37.825: Must I require the recipient to obtain prior approval from the Government for changes in plans?

If it is an expenditure-based award, your agreement must require the recipient to obtain the agreement administrator's prior approval if there is to be a change in plans that results in a need for additional Federal funding (this is unnecessary for a fixed-support TIA because the recipient is responsible for additional costs of achieving the outcomes). Other than that, the program official's substantial involvement in the project should ensure that the Government has advance notice of changes in plans.
