ITEM SUMMARY

To ratify an expenditure in the amount of $663,930 for Bridge Repairs Phase IV - Repair at Parker Road and Indian Creek, Project No. ENG-S-7456, from A&B Construction, LLC for the Engineering Department; and authorizing the City Manager to execute all necessary documents. Approved

BACKGROUND

The Engineering Department received a proposal in August, 2024 from A&B Construction, LLC, for the Bridge Repair Phase IV - Repair at Parker Road and Indian Creek project. A&B Construction, LLC submitted a proposal in the amount of $663,930 which was accepted by the Engineering Department.  The project includes the removal and replacement of a 12” water transmission line via boring methods to provide adequate cover for the new water line in bedrock, and minor restoration of the medians after completion on either side of the bridge.

 

In the Summer 2024, the Engineering Department received notification from City of Plano Public Works Department that a 12” water main under the Parker Road bridge at Indian Creek was completely exposed in the creek beneath the bridge, perpendicular to the flow of the creek.  There is extensive erosion that has caused the exposure of this water line over time, and it also appears the water line was not originally placed deep enough within the creek bed to avoid exposure. Engineering immediately tasked Huitt-Zollars with providing design to lower the water main to sufficient depths within rock bedding beneath the creek via boring methods.

 

It is the conclusion of the Engineering Department and the hired structural and utility engineers with Huitt-Zollars, that the repair is urgent and presents potential failure of the water line transmission line and system outages for this area in the west side of Plano. This situation could compromise the safety and welfare of residents and citizens that live in this area, and downstream of the pipeline in the event of a failure of this water line. In the opinion of our team, this situation requires emergency action available under Texas Local Government Code Sec 252.022:

 

Sec. 252.022. GENERAL EXEMPTIONS

(2) a procurement necessary to preserve or protect the public health or safety of the municipality’s residents;

(3) a procurement necessary because of unforeseen damage to public machinery, equipment, or other property

 

If this project is not awarded, there is potential for future failure of the water line underneath Parker Road and Indian Creek, compromising the safety of residents both up and downstream of Indian Creek, resulting in extensive water service outages, reducing their quality of life, and potentially causing a far greater amount of remediation costs in the future to mitigate failure to the water line and damages downstream. 

FINANCIAL SUMMARY/STRATEGIC GOALS

Funding for this item is available in the 2024-25 Water CIP.  Emergency construction services for the Bridge Repairs Phase IV - Repair at Parker Road and Indian Creek project, in the total amount of $663,930, will leave a balance of $1,070 for future expenditures.

 

Approval of this item will support the City's Strategic Plan Critical Success Factor of being an Excellent, Innovative, and Accountable City Government.
