Section 633.27 - Implementation of a project management plan(a) Upon approval of a project management plan by the Administrator the recipient shall begin implementing the plan.(b) Generally, a project management plan must be modified if the project is at a new phase or if there have been significant changes identified. If a recipient must modify an approved project management plan, the recipient shall submit the proposed changes to the Administrator along with an explanation of the need for the changes.(c) A recipient shall submit periodic updates of the project management plan to the Administrator. Such updates shall include, but not be limited to: (3) Financing, both capital and operating;(4) Ridership estimates, including operating plan; and(5) Where applicable, the status of local efforts to enhance ridership when estimates are contingent, in part, upon the success of such efforts.(d) A recipient shall submit current data on a major capital project's budget and schedule to the Administrator on a quarterly basis for the purpose of reviewing compliance with the project management plan, except that the Administrator may require submission more frequently than on a quarterly basis if the recipient fails to meet the requirements of the project management plan and the project is at risk of materially exceeding its budget or falling behind schedule. Budget and schedule changes will be analyzed on a case-by-case basis, but FTA generally will consider any cost increase or schedule delay exceeding five percent as a material change. Oversight of projects monitored more frequently than quarterly will revert to quarterly oversight once the recipient has demonstrated compliance with the project management plan and the project is no longer at risk of materially exceeding its budget or falling behind schedule.
