Recommendation/Action(s):
Adoption of the attached resolutions.
Summary:
The City Council approved a Cooperative Construction Agreement with Blue Earth County at the April 13, 2026 City Council meeting. The agreement identifies the City of Mankato’s cost share of the County’s plans to improve 3rd Avenue (CSAH 5) between Riverfront Drive and Cleveland Street. Since the execution of this agreement, the County has received bids and the City’s share of project cost has exceeded the amounts outlined in the original agreement.
The following table summarizes the City’s original and amended costs which are outlined in the attached Bid Schedule I.
Original Cooperative Construction Agreement $3,378,266.66
Amended Cooperative Construction Agreement $3,654,170.02
Difference $275,903.37
% Increase 8%
The proposed increase is due to higher bid prices than were estimated at the time of the original agreement. The higher bids were most significant for the underground utility work and pricing was observed to be competitive across all three bids received.
Construction is expected to begin in early June with work broken into three stages – A, B and C. Stage A substantial completion date is October 31, 2026. The final contract completion date is September 1, 2027.
Stage A – Riverfront Drive to Brooks Street (2026)
Stage B – Cleveland Street to Lind Street (2027)
Stage C – Lind Street to Brooks Street (2027)
In order to facilitate the construction of this project, staff recommend authorizing the City Manager to enter into a Professional Services Agreement with Bolton & Menk, Inc. for construction services consisting of construction administration, observation, staking and completion of record drawings for the city-owned sanitary sewer and watermain only. The proposed work order is for an amount not to exceed $226,500.00.
The estimated overall project cost for the City of Mankato is $3,961,285, which includes the amended City Cost Participation along with direct costs for construction engineering for city-owned sanitary sewer and watermain infrastructure.
