CC Regular Session 7.2. Meeting Date: 06/ 13/2023 By: Bruce Westby, Engineering/Public Works Information Title: Adopt Resolution #23-122 Accepting Bids and Awarding Contract for Pavement Maintenance Project #23-16, 2023 Pavement Patching Contracted Services Purpose/Background: The purpose of this case is to adopt Resolution #23-122 accepting bids and awarding a construction contract for Pavement Maintenance Project #23-16, 2023 Pavement Patching Contracted Services. Background: Dozens of miles of City streets have significant numbers of potholes deeper than 2-inches and/or numerous areas where the upper 2-inches or less of pavement are missing, which is generally known as surface stripping. This is resulting in poor and unsafe conditions for drivers and pedestrians. The number of streets exhibiting these severe pavement distresses have grown significantly in recent years, resulting in the Public Works department spending more and more time patching potholes and less time completing other core duties. In 2023, the number of streets with significant numbers of deep potholes and surface stripping have increased to the point that Public Works staff are able to maintain only a portion of them. This is due in part to last winter's severe weather conditions, but also due to the age and composition of the pavement sections, as well as not receiving regular proactive maintenance treatments over the life of the pavement. On April 25, 2023, the City Council adopted Resolution #23-089 approving plans and specifications and authorizing advertisements for bids for Improvement Project #23-14, 2023 Critical Mill and Overlay Improvements. The intent of this project is to temporarily repair pavement sections in 21 of the most critical areas by completing 2-inch mill and overlay improvements. That same evening, the City Council directed the City Engineer to solicit quotes for contracted pavement patching services to immediately patch as many of the highest priority potholes as practical and to present quotes to the City Council for consideration of awarding a contract on May 9, 2023. Improvement Project #23 -14 will be under construction soon, and project #23-15, Priority Pothole Patching, was completed on June 7th. On April 25, 2023, the Ramsey City Council also directed the City Engineer to prepare plans for patching all other identified streets experiencing severe pavement distress and to present said plans to the City Council for consideration of approving plans and authorizing bids for said pavement patching services on May 9, 2023. Attached is the original plan showing all streets proposed to receive temporary 2-inch mill and overlays, temporary deep pothole patching, and temporary spray patching as prepared by Staff this Winter/Spring. Also attached are the plans showing all remaining streets that Staff has identified as requiring temporary pavement repairs in the form of deep pothole patching (Figure 1) and spray patching (Figure 2). Approximately 19.6 miles of City streets are identified in Figure 1 as needing deep pothole patching, and approximately 20.8 miles of City streets are identified in Figure 2 as needing spray patching. Some overlap exists between the maps since some streets will require deep pothole patching before they can be spray patched. Deep pothole patching involves cleaning debris and water out of potholes deeper than 2-inches using compressed air, applying bituminous tack coat on existing bituminous pavement surfaces within the potholes, placing hot asphalt mix in the potholes, then compacting the hot mix. Spray patching involves using a spray patching truck to clean debris and water out of potholes 2-inches deep or shallower using compressed air, then applying a bituminous spray patch mix within the shallow potholes.
