Title
Consider Authorizing The City Manager To Approve A Construction Contract With 3D Paving & Contracting, LLC For The Webb Chapel Road Reconstruction Project In An Amount Not To Exceed $3,945,845.00.
Body
BACKGROUND:
This contract will provide for the reconstruction of Webb Chapel Road from Belt Line Road to the Gateway Lane. Webb Chapel Road is a six-lane divided arterial road and was included in the list of potential roadway projects for the 2022 Bond. The project consists of replacing approximately 2.23 lane miles of pavement, constructing 2,500 LF of sidewalk, 1,850 LF of water line, and median landscaping and irrigation. As part of the project, and included in the sidewalk total, a new sidewalk will be constructed along the west side of Webb Chapel Road to provide additional pedestrian connectivity.
FINANCIAL IMPLICATIONS:
Eight (8) proposals were received on September 11th, 2024, ranging from $3,793,845.00 to $5,180,025.00. State Law requires evaluation of all selection criteria which included not only the price but the validity or reliability of the price along with contractor qualifications, which includes performance on past similar projects, experience of personnel assigned to the project, magnitude of municipal work, etc.
In consideration of all selection criteria, 3D Paving & Contracting, LLC has submitted the lowest qualified proposal of $3,793,845.00. 3D Paving Contracting, LLC also has an excellent reputation with Carrollton and has successfully delivered several projects including the 2022 Alley Replacement project, Crosby Street Reconstruction, and Nob Hill Phase 1 Street Reconstruction project. Upon incorporation of all selection criteria based on price and qualifications, 3D Paving Contracting, LLC is concluded to be the most qualified contractor for this project and offers the best overall value to the City.
With this road 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 Webb Chapel Road Reconstruction is recommended at approximately 4% (original contract amount) or $152,000.00.
Funding is available in Accounting Unit 854460 (Streets Consolidated) and 855160 (Utility Consolidated).
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:
• Sustaining quality of life - Improvements to the sidewalk will promote pedestrian connectivity and safety along the thoroughfare.
• Sustaining day-to-day operations - The replacement of substandard street pavement and water lines should reduce the need for non-scheduled or emergency repairs
