Title:
Adopt Resolution #23-104 Accepting Bids and Awarding Contract for Improvement Project #23-05, Barthel’s Rum River Acres 2nd Street Reconstructions
Purpose/Background:
Purpose:
The purpose of this case is to adopt Resolution #23-104 accepting bids and awarding contract for Improvement Project #23-05, Barthel’s Rum River Acres 2nd Street Reconstructions.
Background:
City Improvement Project #23-05 proposes to reconstruct the streets within the Barthel’s Rum River Acres 2nd subdivision, generally located between 161st Avenue and 164th Avenue, adjacent to the Rum River. The streets are 24 feet wide rural section with drainage swales along both sides of the streets, totaling 1.64 miles in length. A street segment summary is attached to this case for reference.
Project History
The streets within the subdivision were built in 1988. Pavement maintenance has included an initial round of crack seal / seal coat improvements in 1994. In 1997 161st Lane and Dysprosium Street received overlay improvements. All street segments received 2 more rounds of crack seal / seal coat improvements in 2001 and 2009. Maintenance crews have performed patching over the last several years, including patching some areas of the road with clay subgrade coming to the surface. 2021 PASER values we 2 for all street segments. 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 averages were between 3.0 and 3.7 inches thick on the various street segment. Aggregate base thickness was found to vary between 4.0 and 4.6 inches thick. GPR data was not available for some street segments. The GPR summary is included in the attached street segment summary.
Proposed Improvements
Staff review of the geotechnical report found a mix of native sandy and clayey alluvial soils made up the sub-base material. The sandy materials are well suited for pavement support and are considered non-frost susceptible and are also free draining materials. The clayey soils are considered undesirable materials, and are proposed to be replaced with 2 feet of select granular material on top of geotechnical fabric. Generally, these subsoil corrections are proposed along 164th Avenue, the northern portion of Germanium Street, and 161st Avenue connecting into the Estates of Silver Oaks subdivision. Additionally, the southern portion of Germanium Street and adjacent 161st Lane was found to have a high-water table, which seasonally impacts the strength of the pavement section. The project proposes to raise the elevation of the pavement approximately 1-foot to allow the pavement section to be dry during seasonally high-water. In the areas not requiring corrections, Staff is proposing to use a pavement section made up of 6-inches in-place reclamation material below 3.5-inches of new bituminous pavement.
This project proposes to remove the stub street at the corner of Dysprosium Street and 161st Lane, and create a true corner, since the development of the adjacent Scout Camp property is not currently proposed to occur.
In general, the current swales along the streets are not proposed to be re-graded as part of this project. Due to the nature of subsoil corrections, and raising the profile of the pavement, some areas of the project will have impacts to the in-slopes between the pavement and bottom of the swales. No changes to the current drainage patterns are proposed. The existing culverts crossing the streets are proposed to be removed and replaced, this is to ensure the culverts will last at least through the proposed 60-year design life of the street. Due to the subsoil corrections, drain tile will be added in the low areas to properly drain the pavement subbase. The drain tile is proposed to drain into the existing swales.

Funding Source:
Funding for this improvement is proposed to come from Pavement Management Funds and Stormwater Utility Funds.
Bids were advertised on Friday, April 28, and again on Friday May 5, 2023, in the City’s official newspaper, the Anoka Union Herald. On May 19, 2023 a total of three (3) bids were received, opened, and tabulated, and the following bids were found to comply with the advertisement for bids.
The bid of Douglass-Kerr Underground, L.L.C. in the amount of $1,198,428.85 for the total bid construction of said improvements in accordance with the approved plans and specifications and advertisement for bids, is the lowest responsible bidder. Adding indirect costs in the amount of 23-percent brings the total project costs to $1,474,067.49.
The low bid is 20-percent less than the engineer’s estimate, primarily due to lower than anticipated bituminous and excavation costs.
Funding Source Breakdown:
Hakanson Anderson submitted a proposal for construction staking of the proposed improvements for a total not-to-exceed amount of $13,540.00. The construction staking is included in the indirect project costs, and proposed to be paid with Pavement Management funds.
City Staff proposes to administer and inspect construction. Plans and specifications were prepared in-house as part of Staff’s normal duties.
