AGENDA ITEM COVER SHEET

Agenda Title:

Purchase order 22000039, in the amount of $125,00.00 was issued to Superior Bowen Asphalt Co LLC for emergency asphalt street repairs at the intersection of Noland Road & 24 Highway for the Water Department.

Recommendations:

Staff is providing notification to the City Council of this purchase.

Background:

A water main break occurred below the south side of the intersection of US HWY 24 and Noland Rd. in October, 2019. The water main break was located below a buried abandoned concrete pedestrian tunnel which created a very challenging repair. The break and repair resulted in a full closure of Noland Rd. along the south side of the major intersection. The repair work was completed around the clock to get the major intersection reopened as soon as possible.

Due to the depth of the water main break and the challenge of working around the abandoned tunnel it is assumed that pockets of backfill material may not have been adequately compacted at the time of the repair. This appears to have resulted in settling of the pavement subbase which has caused dips in the pavement across the intersection. Temporary asphalt is typically used for a period of time following backfill to allow for settlement prior to making the final road repair. However, due to the traffic impact at the major intersection, the final road repair had to be made immediately following backfill.

Superior Bowen has successfully completed numerous projects similar in size and scope for the City in the past. Superior Bowen also had a contract with the City for the 2019, 2020 Asphalt Overlay Program as well as the 2021 Full and partial depth asphalt patching program. An emergency pavement repair is required as the rate of pavement subbase displacement may continue to increase with the high volume of traffic at the intersection. The work started on July 13, 2021.

Approval of this item shall authorize change orders up to a total of ten (10) percent of the original authorized amount for each order, provided appropriations are available.
