Title
Consider Authorizing The City Manager To Approve A Construction Contract With Garret Shields Infrastructure, LLC For The Whitlock Addition Street Reconstruction Phase 3 Project In An Amount Not To Exceed $7,007,354.10.
Body
BACKGROUND:
This contract will provide for the reconstruction of four (4) streets in the Whitlock Addition Subdivision including Ryan Avenue, E Russell Avenue, Norris Street, portions of Homer Street, associated alleys, and the parking lot at WJ Thomas Park. The project consists of approximately 6,000 LF of residential street pavement, 4,000 LF of alley pavement, and 2,000 LF of storm pipe. This project was a part of the 2018 Bond Election.
The duration of construction is 540 calendar days. Construction sequencing will ensure that not all streets are under construction simultaneously. Project signage will be installed subdivision entrances, and residents will receive written notice prior to construction. A neighborhood meeting with the residents and the contractor will be held prior to mobilization. Additional handouts will be distributed as required during the project.
FINANCIAL IMPLICATIONS:
Sixteen (16) bids were received on February 11, 2026. The low bid, in the amount of $6,677,354.10, was submitted by Garret Shields Infrastructure, LLC. The Engineer’s Estimate for the project was $9,330,000.00. Garret Shields is currently constructing Cemetery Hill Road and Cromwell Drive and has performed satisfactorily so far during construction. They also have positive references from the City of Plano, North Richland Hills, and Highland Village. Funding is available in Account Unit 854460 (Streets Consolidated).
With this neighborhood reconstruction staff recommends the inclusion of a construction contingency. The construction contingency provides an expedient manner to accommodate unforeseen costs and minor additions in work common in all construction projects. Examples include unexpected conditions discovered during construction, and changes to design that were not possible during plan generation. All charges against contingency must be supported by detailed pricing information and approved by the City through a formal change order. However, having advanced Council authorization ensures that work progress is not impeded. Typical construction contingencies for a project of this magnitude range from 2-5% of the total contract amount. As a cost control measure, the construction contingency for the Whitlock Addition Street Reconstruction Ph 3 is recommended at 5% (original contract amount) or $330,000.
IMPACT ON COMMUNITY SUSTAINABILITY:
This project will support the City Council’s strategic objectives and vision of building a community that families and businesses want to call home by:
• Improving neighborhood safety and reliability through full-depth street, alley, and storm drainage reconstruction that addresses aging infrastructure. (Accessible)
• Protecting long-term public investment by reconstructing infrastructure to current standards, reducing future emergency repairs and lifecycle costs. (Economical)
• Revitalizing an established neighborhood by improving curb appeal, pavement condition, and park access. (Revitalized)
STAFF RECOMMENDATION/ACTION DESIRED:
Staff recommends award of the construction contract for the Whitlock Addition Street Reconstruction Phase 3 Project to Garret Shields Infrastructure, LLC in the amount of $7,007,354.10 ($6,677,354.10 original proposal and $330,000 (5%) construction contingency).
