Information

Department Action

The DNT Southbound Frontage Road project has been completed and a final change order is needed to reconcile the quantities that were actually used compared to those that were estimated in the original contract. Attached is a letter from our design and construction management engineering consulting firm, Halff Associates, which lists the quantities that underran and overran, as well as two items to add for the repairs to the signals. The net amount is a reduction of $122,760.25 to the contract.

The contractor met the substantial completion time requirements of the contract by being open to traffic by January 2020. The final completion times were not met because of two crashes which demolished traffic signal controllers at two locations, as well as complications of COVID. This is also addressed in the letter from Halff, who recommends that no liquidated damages be charged for the late final completion because we have had use of the road since January 2020 and the delays caused by the two crashes and COVID are beyond the control of the contractor. The Engineering staff agrees with Halff’s recommendation.

Recommended Action: It is recommended that the Commissioners Court approve Change Order No. 6, reducing the DNT Southbound Frontage Road contract by $122,760.25 for a new total of $17,669,604.59.
