3.02 REVIEW AND APPROVAL

A. Within 5 working days after receipt of the initial CPM network activity listing, the Owner will meet with the Contractor for joint review, correction or adjustment of the Contractor's proposed approach. Within 7 calendar days after the joint review, the Contractor shall submit a revised CPM network reflecting comments offered during the joint review. The Owner will review this resubmission, and may accept it as submitted. The accepted CPM will constitute the Contractor's project work schedule until it is subsequently revised by the Contractor.

B. Acceptance of the CPM is not to be construed as concurrence by Owner that schedule is reasonable or achievable. Any omission of project work from the CPM network or activity listing, otherwise required for Contract compliance, shall not excuse the Contractor from completing such work within any applicable completion date as determined by the Owner.

3.03 UPDATE

A. Twice a month or as agreed, on a date mutually agreed upon, a job-site meeting will be held to review the CPM network, activity listing, and job progress.

B. The conditions under which a revision of the schedule will be required are as follows: 1. When delay in completion of any work item or sequence of work items results in an estimated extension of project completion by either 5 working days or by 10 percent of the remaining duration of time to complete the Contract, whichever is less. 2. When delays in submittals or deliveries or work stoppages are encountered which make replanning or rescheduling of the work necessary. 3. When the schedule does not represent actual prosecution and progress of the work. 4. When Contract modification necessitates schedule revision, submit a subnetwork analysis of all change work with his Proposal. If approved, this subnetwork will become a part of the approved schedule.

C. As part of this review, prepare a brief narrative report relating to the status of construction, submittals, approvals, and procurement. Indicate in the report areas
