2.4.34 A change mechanism can also be included in the contract for dealing with changes to the service, such as additions or deletions to the project facilities, new service requirements or any volume changes. Appropriate arrangements will need to be included in the contract and payment mechanism to reflect the impact of any service changes on the payment mechanism and the unitary charge. For example, in a PPP sports stadium project, the contract should state clearly the increases in payments by the public agency if it needs to use the stadium for days that the public agency has not reserved for the government's use only.
2.4.35 For service changes, the public agency and the private provider will have to agree on:
a) The amended method of service delivery (if applicable);
b) The adjusted price for the services or additional services;
c) Whether there are capital payments needed; and
d) Changes to the performance measurement system.
