Adopt Resolution #24-130 Accepting Bids and Awarding Contract for Improvement Project #24-55, 2024 Pavement Patching Contracted Services

Purpose:
The purpose of this case is to adopt Resolution #24-130 accepting bids and awarding a construction contract for Improvement Project #24-55, 2024 Pavement Patching Contracted Services. 
 
Background:
In 2023, the number of City streets having significant numbers of deep potholes and surface stripping increased to the point that Public Works staff were able to maintain only a small portion of them.  This was due in part to the previous winter’s severe weather conditions, but also due to the age and composition of the pavement sections, as well as to not receiving regular proactive maintenance treatments over the life of the pavement sections.  In 2023, the City spent almost $1.3M on contracted pavement patching services.
 
The mild conditions this winter helped prevent a repeat of last year as related to the scope and severity of potholes observed across the City.  This spring, staff drove all City streets and identified various street segments in 4 residential neighborhoods totaling 4.12 miles that will benefit most from skim patching, which is generally a one-inch minus bituminous overlay.  Other streets were identified that would benefit most from spray patching, which include streets in 2 neighborhoods totaling 0.91 miles.  City staff will patch pavement on all remaining 182-plus miles of paved City streets.
 
Attached is a figure showing the streets staff proposes to patch using contracted services in 2024.  Streets highlighted in red are proposed to be spray patched, whereas streets highlighted in blue are proposed to be skim patched.  This case only addresses the proposed skim patching work.
 
City streets identified for skim patching in 2024 have numerous deep potholes (deeper than 2-inches) that will require hand patching before skim patching operations commence.  Below is a summary of the skim patching process;

• City crews will sweep streets first.
• Contractor will blow debris and water out of deep potholes using compressed air.
• Contractor will apply bituminous tack coat to potholes.
• Contractor will patch deep potholes with hot mix, then compact it.
• Contractor will apply bituminous tack coat to existing pavement and patched potholes.
• Contractor will skim patch/overlay both sides of street centerlines to a total width of 26-feet, leaving the outside 2+ feet in each direction unpatched to ensure drainage will continue to work.
• Contractor will compact the new pavement with rubber-tired rollers.
• City will sweep patched streets full width following completion of skim patching.

To date this work product appears to be holding up very well.
 
Tentative project schedule:

• June/July - Start construction
• August - Final completion

Alternative #1: Motion to adopt Resolution #24-130 accepting bids and awarding a construction contract for Improvement Project #24-55, 2024 Pavement Patching Contracted Services, to GMH Asphalt Corporation in the amount of $276,560.  
 
Alternative #2: Motion of other.  

Payment for this work is proposed to come from the $575,000 in funds budgeted for 2024 crackseal, pavement rejuvenator, and pavement patching projects.
 
Staff will request Council approval to solicit quotes for spray patching for the identified 0.91 miles of streets after it is known how much funding remains from the $575,000 budgeted for 2024 crackseal, pavement rejuvenator, and pavement patching projects.
