Consider Recommending City Council Approving Plans and Specifications and Authorizing Advertisement for Bids for Sunwood Drive and Waco Street Reconstruction, Improvement Project #22-01

Purpose:
The purpose of this case is to consider recommending City Council approving plans and specifications and authorizing advertisement for bids for Sunwood Drive and Waco Street Reconstruction, Improvement Project #22-01.
 
Background:
City Improvement Project 22-01 proposes to reconstruct Sunwood Drive between Trunk Highway 47 and Waco Street, and Waco Street between Sunwood Drive and 150^th Avenue. The streets total approximately 2,500 lineal feet (0.48 miles) in length, and are 44 feet wide as measured to the face of curb.
 
Project History

• 2022 – 2031 Capital Improvement Program – listed as street reconstruction for 2022
• August 10, 2021 City Council accepted proposals for geotechnical report and topographic survey
• August 24, 2021 City Council accepted proposals for utility testing
• October 26, 2021 City Council ordered plans and specifications
• December 14, 2021 City Council authorized reconstruction of Waco Street to existing pavement widths

 
Pavement History
Sunwood Drive and Waco Street were constructed in 1985 and 1992 respectively. Pavement maintenance has included crack seal / seal coat improvements in 1992 (Sunwood Drive), 2006, 2013. Maintenance crews have performed patching over the last several years, including extensive spray patching. No pavement overlay improvements have been performed on these street segments. 2021 PASER values were 4 for Sunwood Drive and 3 for Waco Street.
 
Ground Penetrating Radar (GPR) was performed on the street segments. Bituminous pavement thickness was found to have an average thickness of 4.20 inches on Sunwood Drive and 3.9 inches on Waco Street. GPR was not able to reliably identify the aggregate base thickness, however, the soil borings performed as part of the geotechnical report found an average of 6.4 inches.
 
Proposed Improvements
Sunwood Drive and Waco Street are Municipal State Aid (MSA) streets, and must comply with State Aid design requirements. MSA design requires these to be a 10-ton design. Based on the traffic counts performed in 2021 (1,800 ADT Sunwood, 580 ADT Waco), the required pavement section is 5” aggregate base and 4” bituminous pavement.
 
Staff review found the existing pedestrian ramps within the project area did not meet current ADA requirements, therefore all six pedestrian ramps will need to be removed and replaced. The concrete curb and gutter were found to generally be in good condition, and only spot repairs are proposed. Staff is proposing minimal impacts to the existing bituminous trail with the project beyond what is required for matching into the new pedestrian ramps. The south leg of trail at the intersection of Sunwood Drive and Trunk Highway 47 is proposed to be straightened, the current 90-degree corner is a hazard for plowing.
 
Review of the sanitary sewer and watermain did not find issues requiring repair. 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.
 
Televising of the storm sewer system found more issues than anticipated, and will require removal and replacement of six storm sewer structures and their connecting pipes. The majority of this work will be concentrated at the intersection of Sunwood Drive and Zuni Street.
 
The current pavement marking layout meets State Aid standards, and the road is proposed to be marked back to the existing layout.
 
Generally, impacts to boulevards will be minor, just as necessary for removal and replacement of concrete curb and gutter, pedestrian ramp improvements, and excavation required for the storm sewer repairs.
 
Build Process

• Full-depth reclamation of existing bituminous pavement and aggregate base
• Storm sewer repairs
• Project removals (spot curb and gutter, pedestrian ramps, driveways as needed)
• Place new concrete curb and gutter and pedestrian ramps (5 to 7-day cure time)
• Remove excess reclaim material, shape and compact 5 inches of remaining material
  • Excess reclaim is stockpiled and will be used on future City projects
• Place first lift of bituminous pavement
• Finish any trail and driveway repairs
• Restore the boulevard in any impacted areas
  • 4 inches topsoil, seed and hydro-mulch
• Place the final lift of bituminous pavement
• Place all pavement marking, must wait 72 hours of 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
  • April 26, 2022
• Contractor begins construction
  • June 2022
• Contractor Substantially Completes construction
  • September 2, 2022
• Contractor Final Completion (project clean up, punch list created)
  • September 30, 2022

 
State Aid Approval
Plans are currently being routed through State Aid for approval, which is required before project bids can be accepted. Staff does not anticipate significant comments from State Aid which would require moving the proposed project bid opening.  

Full 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, as well as a plan sheet showing the typical sections, which includes information on the proposed pavement section. 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.
