Authorization To Execute Contract With Minnowa Construction, Inc., And Amend Transportation Capital Improvement Program Budget For Reconstruction Of Bridge Number 19578 In Vermillion Township, County Project 85-23
end
PURPOSE/ACTION REQUESTED
Authorize to execute a contract with Minnowa Construction, Inc., for County Project (CP) 85-23, the reconstruction of Bridge Number 19578 in Vermillion Township, and to amend the Transportation Capital Improvement Program budget accordingly.
SUMMARY
To provide a safe and efficient transportation system, Dakota County is reconstructing the bridge at County State Aid Highway (CSAH) 85 and 0.9 miles north of CSAH 62. This project will replace the existing bridge which has a deteriorating deck and substructure and needs full replacement.
The project was advertised, and bids were opened and tabulated on June 2, 2026. Three bidders submitted bids as follows:
Bidder Bid Amount
Minnowa Construction, Inc. $2,471,682
Lunda Construction Co. $2,552,742
Redstone Construction, LLC $2,560,914
The low bid from Minnowa Construction, Inc., in the amount of $2,471,682, is approximately 6.5 percent above the engineer’s estimate, which is reasonable for a full bridge replacement involving foundation and substructure work. The original CIP funding for CP 85-23 was based on a planned bridge deck replacement only, but detailed engineering and field evaluations performed in 2025 determined that the existing bridge’s condition warranted a full bridge replacement to meet current state-aid standards. As a result, the project scope and cost increased.
To fully fund the bridge construction, project contingency, and the required non-CSAH contribution, a Transportation Capital Improvement Program budget amendment of $2,489,200 is required. This amendment reflects the updated programmed funding plan for CP 85-23, including $2,198,400 for construction, $197,800 for contingency, and $93,000 in non-CSAH funding.
RECOMMENDATION
recommendation
Staff recommends awarding the construction contract for CP 85-23 to Minnowa Construction, Inc., in the amount of $2,471,682, and approving a Transportation Capital Improvement Program budget amendment of $2,489,200 to fully fund construction, contingency, and non-CSAH requirements.

EXPLANATION OF FISCAL/FTE IMPACTS
To fully fund the bridge construction, project contingency, and the required non-CSAH contribution, a Transportation Capital Improvement Program budget amendment of $2,489,200 is required. The amendment consists of $93,000 in Transportation fund balance and $2,396,200 in County State Aid Highway (CSAH) funds. This reflects the programmed funding plan for CP 85-23, including the increased construction cost due to the need for full bridge replacement rather than the originally planned deck replacement.
