Consider Recommending City Council Approving Plans and Specifications and Authorizing Advertisement for Bids for 2022 Neighborhood Pavement Overlay Improvements, Improvement Project #22-04

Purpose:
The purpose of this case is to consider recommending City Council approving plans and specifications and authorizing advertisement for bids for 2022 Neighborhood Pavement Overlay Improvements, Improvement Project #22-04.
 
Background:
City Improvement Project 22-04 proposes to overlay the streets within the Sunfish Lake Business Park 2^nd, Sunflower Ridge, Tiger Meadows, and The Ponds of Ramsey subdivisions. The streets total approximately 14,200 linear feet (2.69 miles) in length, vary in width between 32 and 42 feet, and are urban sections. A street segment summary is attached to this case.
 
Project History

• 2022 – 2031 Capital Improvement Program – listed as street overlay for 2022
• August 10, 2021 City Council accepted proposals for topographic survey
• October 26, 2021 City Council ordered plans and specifications

 
Pavement History
The streets within the subdivisions were generally built between 2002 and 2003. Pavement maintenance has included 2 crack seal / seal coat improvements. 2021 PASER values were 7 for all street segments. Ground Penetrating Radar (GPR) was performed on some of the street segments within the project area, and are summarized in the street segment summary.
 
Proposed Improvements
Based on Staff review of the existing pavement sections, and condition of the existing pavements, a mill and overlay of the existing pavement is appropriate. The proposed mill and overlay will vary between 1.5 and 2 inches thick dependent upon the existing pavement thicknesses.
 
Staff review found the existing pedestrian ramps within the project area did not meet current ADA requirements, therefore all pedestrian ramps within the project area will need to be removed and replaced. The concrete curb and gutter in the project area were found to generally be in good condition, and only spot repairs are proposed.
 
Minor repairs to the existing storm sewer structures are proposed with this project, the majority of which are grouting the existing adjustment rings and pipe inverts. A few storm sewers catch basins will require resetting due to settling.
 
The City will be placing inflow and infiltration (I/I) barriers on the sanitary sewer manholes with this project. The City received an MCES I/I Grant for this work, which will reimburse the City for the costs associated with the I/I barriers.
 
Build Process

• Project removals (spot curb and gutter, pedestrian ramps)
• Place new concrete curb and gutter and pedestrian ramps (5 to 7-day cure time)
• Mill existing pavement
• Finish structure adjustments, storm sewer catch basin repairs
• Restore the boulevard in any impacted areas
  • 4 inches topsoil, turf
• Place bituminous pavement
• Place all pavement marking, must wait 72 hours after paving

 
Preliminary Schedule Remaining

• Council Approves Plans and Specifications / Authorizes Ad for Bids
  • March 22, 2022
• Staff Receives Bids
  • April 18, 2022
• Council Awards Contract to the lowest responsible bidder

• Contractor begins construction
  • June 2022
• Contractor Substantially Completes construction
  • September 2, 2022

Final plans are not attached to this case to prevent potential bidders from downloading plans attached to the case to prepare and submit their bids, rather than purchasing the plans through QuestCDN, the electronic bidding software used by the City of Ramsey. This ensures all bidders are bidding off the same set of plans, and all bidders are notified of any plan revisions (addenda) issued during the bidding process. Attached is the title sheet showing the scope of the improvements. Plans are available upon request from the City Engineer.

Staff estimates up to 10 minutes will be needed to present this case and respond to questions.
