PURPOSE:
Does city council support approval of a construction contract with E&M Concrete, LLC for the 2024 Miscellaneous Concrete Project, City Project No. 24-05?
LONG-TERM OUTCOME(S) SERVED:
Safe Community; High-Quality Governance
DISCUSSION:
The City of Littleton’s Public Works Department’s pavement management program includes performing concrete repairs prior to surface sealing or resurfacing projects. Replacing concrete in advance of pavement preservation work provides high value by improving drainage and providing a stable edge to seal or pave against, as well as optimizing the value of preservation projects.
The 2024 Miscellaneous Concrete Project will repair concrete on the streets identified for the 2025 Surface Sealing Project. The city advertised the 2024 Miscellaneous Concrete Project on June 5, 2024. The bids were opened on June 21, 2024. Staff reviewed the submitted bids and finds that E&M Concrete, LLC is the lowest and most qualified bidder. Staff has contacted references on previous projects with E&M and find them competent to complete this concrete project. With the support of Council in this Resolution, it is anticipated that construction will commence in early-August, with a completion of late-October.
Execution of this contract would authorize the concrete work within various neighborhoods in the city, to be completed at the accepted bid proposal amount outlined in the Bid Tabulation Sheet.
BACKGROUND:
The City of Littleton has about 360 lane miles of streets within the community’s transportation network. Littleton’s Public Works Department is responsible for the preservation and maintenance of the streets throughout the community, including the concrete curbs and gutters adjacent to the streets. Maintaining the adjacent concrete to the pavement is a best practice for preserving the asphalt surfaces, as well as protecting the financial investment of the preservation treatments.
The Engineering Division of Public Works uses condition ratings and specific preservation and rehabilitation practices to preserve the condition of Littleton’s roadways and extend the useful life of the pavement. Engineering staff assesses the condition of each roadway segment and assigns a Pavement Condition Index (PCI) rating ranging from 0 to 100. A PCI of 100 corresponds to a new road, a PCI rating of 0 means the pavement has completely failed. The PCI rating drops over time as pavements deteriorate from use and environmental factors. The rate of degradation begins slowly and increases rapidly after a few years. As such, pavement preservation early in a street’s lifecycle is critical to preserve the pavement quality and reduce costly rehabilitation or reconstruction.
The Engineering Division manages the Pavement Management Program with a goal to keep Littleton’s streets at a PCI of 75 or higher. Currently, the average PCI across the street network is 57. The pavement management strategy focuses on identifying the correct preservation treatment, and applying it at the right time, to extend the life of the pavement. This holistic program approach effectively preserves the pavement network thorough leveraging low-cost preservation techniques to limit future reconstructions and provides the most value from the funding available for pavement management.
Concrete curbs and gutters protect the roadway from water getting underneath the pavement; water can soften the subgrade and cause failures of the pavement above. Maintaining the concrete curbs and gutters adjacent to the pavement is a best practice for preserving the asphalt surfaces, as well as protecting the financial investment of the preservation treatments.
The 2024 Pavement Management Program includes crack repairs, miscellaneous concrete repairs, high quality patching, mill and overlay, and street reconstruction on various streets throughout the city. The 2024 Miscellaneous Concrete Project will repair concrete in the areas identified in for pavement preservation in 2025. The following map illustrates streets included in the 2024 Miscellaneous Concrete Project.
Prior Actions or Discussions
This project has not previously been discussed with city council.
FISCAL IMPACTS:
The proposed construction contract with E&M, LLC for the 2024 Miscellaneous Concrete Project, City Project No. 24-05 is $1,024,033.00. This project will be funded from the Capital Projects Fund.
STAFF RECOMMENDATION:
Staff recommends approval of the Construction Contract.
ALTERNATIVES:
If the contract is not approved, the concrete repairs will not be performed in advance of the pavement preservation treatments. The concrete will continue to deteriorate, potentially degrading the existing pavement and future surface seal. Future repair costs would likely be greater due to inflation and increased construction costs.
PROPOSED MOTION:
Proposed Motion
I move to approve Resolution 82-2024 approving a Construction Contract with E&M, LLC for the 2024 Miscellaneous Concrete Project, City Project No. 24-05.
