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:

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,...
