PURPOSE:
Does city council support approval of a construction contract with Metro Pavers, Inc. for the 2024 Mill & Overlay Project, City Project No. 24-03?
LONG-TERM OUTCOME(S) SERVED:
Safe Community; High Quality Governance
DISCUSSION:
The City of Littleton’s Public Works Department advertised the 2024 Mill & Overlay - Arapaho Hills City Project No. 24-03. The city’s pavement management plan identified the streets within the Arapaho Hills Neighborhood for resurfacing. The bids were opened on May 29, 2024. Staff reviewed the submitted bids and finds that Metro Pavers, Inc. is the lowest and most qualified bidder. Staff has worked with Metro Pavers, Inc. on previous projects and find them competent to complete this mill and overlay project. With the support of council in this Resolution, it is anticipated that construction will commence in mid-July, with a completion of mid-September.
Execution of this contract would authorize the mill and overlay work within the Arapaho Hills neighborhood, to be completed at the accepted bid proposal amount outlined in the Bid Tabulation Sheet.
BACKGROUND:
The City of Littleton has approximately 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.
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 goal to keep Littleton’s streets at a PCI of 75 or higher. Currently, the average PCI across the street network is 57. The pavements management strategy focuses on identifying the correct preservation treatment, and applying it at the right time, to extend the life of the pavement.
Surface sealing streets in good condition protects the wearing surface and prevents degradation of the street structure over time. Pavements that have not been adequately sealed and preserved require more intensive activities and repairs over a shorter duration to bring the roadway back to a good condition. The degraded asphalt surface layer must be removed to the still-viable pavement and potentially base below, then provide a new asphalt surface layer. Streets that do not have a viable base or have a fully degraded pavement section must be reconstructed. Preservation techniques must consider the pavement distress to be effective; a surface seal will not improve the condition of a roadway that has a failing base layer. As shown in the image below, surface sealing treatments are significantly less costly than surface replacement or roadway reconstruction activities.
The annual surface sealing, mill and overlay, and street reconstruction projects are annual pavement preservation programs managed by Public Works that identify which streets will receive which treatments in which years. 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. The 2024 pavement management program includes crack repairs, miscellaneous concrete repairs, mill and overlay, and street reconstruction on various streets throughout the city.
Execution of this construction contract with Metro Pavers, Inc. would allow mill and overlay work within Arapaho Hills to occur in the 2024 construction season at the accepted bid amount.

FISCAL IMPACTS:
The proposed construction contract with Metro Pavers, Inc. for the 2024 Mill & Overlay Project, City Project No. 24-03 is $ $1,987,441.77. This project will be funded from both the Capital Reserve Fund (Fund 34 Capital Projects Fund) and the 3A Sales Tax Capital Improvement Fund.
STAFF RECOMMENDATION:
Staff recommends approval of the Resolution approving the construction contract.
ALTERNATIVES:
If the contract is not approved, the pavements in this neighborhood would risk further deterioration to the level requiring a full depth reconstruction. If this were to happen, the overall project cost would be greater based on the increase of work, inflation and increasing construction costs.
PROPOSED MOTION:
Proposed Motion
I move to approve Resolution 73-2024 approving a construction contract with Metro Pavers, Inc. for the 2024 Mill & Overlay Project, City Project No. 24-03.
