Pavement History
The streets within the subdivision were built between 1993 and 1996. Pavement maintenance has included crack seal / seal coat improvement in 1998, 2005, and in 2013. Maintenance crews have performed patching over the last several years, including extensive spray patching. 2021 PASER values ranged between 2 and 6, with the bulk of the subdivision being rated at 2. PASER values of 2 are as low as any street segments within the City.
 
Ground Penetrating Radar (GPR) was performed on the street segments. Bituminous pavement thickness was found to have an average thickness of 2.9 inches. Aggregate base thickness was found to have an average thickness of 4.4 inches. The overall average section thickness was 7.3 inches.
 
Proposed Improvements
Staff review of the geotechnical report found the sub-base material as poorly graded sand and poorly graded sand with silt, these materials are well suited for pavement support and are considered non-frost susceptible and are also free draining materials. With the sub-base material being sufficient, Staff is proposing to use the current standard City pavement section of 4-inches aggregate base, and 3.5-inches new bituminous pavement. The 4-inches of aggregate base is proposed to be composed of recycled reclamation material.
 
Staff review found the existing pedestrian ramps within the project area did not meet current ADA requirements, therefore all four pedestrian ramps 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. Staff is proposing minimal impacts to the existing bituminous trail which crosses through the project, beyond what is required for matching into the new pedestrian ramps.
 
A portion of the cul-de-sac located on the south end of Junkite Street has had some undercutting of the existing concrete curb and gutter. This project proposes to remove and replace a portion of the concrete curb and gutter, perform a full-depth restoration of the compromised road section, and provide a stabilized erosion control mat in the boulevard area to prevent future erosion of the soils.
 
Review of the storm sewer, sanitary sewer and watermain did not find issues requiring repair. The City will be placing inflow and infiltration 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.
 
Construction Process

• Install traffic control measures
  • Traffic control is maintained throughout the project
• Install erosion control measures
• Full-depth reclamation of existing bituminous pavement and aggregate base
• Project removals (spot curb and gutter, pedestrian ramps, driveways as needed)
• Repair catch basins and reset castings
• Install I/I barriers in sanitary manholes
• Place new concrete curb and gutter and pedestrian ramps (add 5 to 7-day cure time)
• Remove excess reclaim material, shape and compact 5 inches of remaining material
  • Subgrade excavation required to remove approximately 0.5 inches below the existing reclamation material to allow 4-inch thickness
  • Excess reclaim is stockpiled and will be used on future City projects
• Place first lift of new bituminous pavement
• Finish any trail and driveway repairs
  • No driveway repairs are anticipated
• Restore the boulevard in any impacted areas
  • 4 inches topsoil, seed and hydro-mulch
• Place the final lift of bituminous pavement
  • Remove traffic control measures as allowed
• Place all pavement marking, must wait 72 hours after paving
• Erosion control measures are removed after restoration has been completed

Alternative #1 – Motion to adopt Resolution #22-104 accepting bids and awarding a construction contract for Wood Pond Hills 2^nd – 5^th Street Reconstructions, Improvement Project #22-06, to North Valley, Inc. for the bid in the amount of $568,135.15.
 
Alternative #2 – Motion to deny adoption of Resolution #22-104 at this time.

Bids were advertised in the Anoka Union Herald and in Finance and Commerce on April 1 and April 8, 2022. On May 2, 2022 a total of five (5) bids were received, opened, and tabulated, and the following four (4) bids were found to comply with the advertisement for bids.
 

CONTRACTOR	TOTAL BID
North Valley, Inc.	$568,135.15
Northwest	$628,243.00
Asphalt Surface Technologies Corp.	$637,047.92
Park Construction Company	$697,471.73
Engineer’s Estimate	$506,368.01

 
The bid of North Valley, Inc. of Nowthen, Minnesota, in the amount of $568,135.15 for the total bid for construction of said improvements in accordance with the approved plans and specifications and advertisement for bids, is the lowest responsible bid. Adding indirect costs for administrative, engineering, finance and legal costs in the amount of 23-percent brings total project costs to $698,806.25.
 
Per the final plans and specifications, estimated construction costs were $506,368.01. After adding 23-percent indirect costs, estimated project costs total $622,832.66.
 
The low bid is 12-percent more than the engineer’s estimate, primarily due to higher than estimated bituminous pavement and aggregate base construction costs.
 
Funding for this improvement is proposed to come from Pavement Management Funds, Stormwater Funds, Sanitary Sewer Funds, and Water Funds. Sanitary Sewer Funds will be reimbursed through an Inflow & Infiltration Grant.
 

• Street Project Costs                $686,682.85
• Storm Sewer Project Cost      $4,549.35
• Sanitary Sewer Project Cost   $5,721.04
• Watermain Project Costs        $1,853.01
• Total Project Costs               $698,806.25

 
Hakanson Anderson proposes to provide construction staking in a total not-to-exceed amount of $1,410.00. These costs are included in the 23-percent indirect costs. Staff feels these costs are reasonable based on the scope of the proposed improvements and required staking and recommends accepting the proposal, which is attached for reference.
 
City Staff proposes to administer and inspect construction.
 
Plans and specifications were prepared in-house as part of Staff’s normal duties.
 
Outside costs incurred to date as engineering indirect costs include:

• $7,520.00 for Haugo Geo Technical Services, LLC to supply a geotechnical report of the project area.
• $13,081.50 for Hydro-Klean, LLC to perform sanitary sewer and storm sewer cleaning and supply reports of pipe conditions within the project area.
• $435.00 for Water Conservation Services, Inc. to perform a water leak test on the watermain system in the project area.
• $3,500 for Hakanson Anderson to collect topographic survey of the project area.

Staff recommends Alternative #1.
