The Owner is not obligated to consider any modified Agency TCP or a TCP developed by the

Contractor. The Agency will not be liable to the Contractor for failure to accept or act upon any request for a modified Agency TCP or a TCP developed by the Contractor.

To conserve time and funds, the Contractor may first submit a written request for a preliminary review by the Owner. The request should contain a description of the proposal together with a rough estimate of anticipated dollar and time impacts. The Owner will, within a reasonable time, respond to the Contractor in writing whether or not the request would be considered by the Agency.

If the Contractor’s request to use a Contractor-modified Agency TCP, or a TCP developed by the

Contractor is approved in whole or in part, acceptance will be made by a Change Order.

The Owner will establish prices that represent a fair measure of the value of Work to be added, changed, or deleted as a result of any accepted modifications to the Agency TCP or an accepted

TCP developed by the Contractor.

Once a TCP has been accepted by the Owner, any additional modifications must be submitted by the Contractor for Agency review following the procedure described above. The Owner is not obligated to consider additional modifications to a previously approved TCP.
