I-535 Blatnik Bridge

Duluth, Minn., and Superior, Wis.

MnDOT and WisDOT announce apparent best value contractor

The Minnesota and Wisconsin Departments of Transportation opened bids for the Blatnik Bridge replacement project Tuesday, June 23, and Ames-Kraemer Joint Venture II was the apparent best value proposer.

MnDOT, lead agency on the project, chose the design-build process for the Blatnik Bridge project. This means MnDOT and WisDOT define the standards and general specifications expected for the bridge project and then hire a contractor to design and construct the bridge to satisfy those requirements. This process was chosen for efficient coordination between the design team and the construction team, a lower cost and more innovative design and construction.

MnDOT often uses a best-value system for design-build projects, which combines a bidder’s technical score and price into a single adjusted score. The lowest adjusted score at project letting determines who will be awarded the contract for the project. Two contractors bid on the Blatnik project. Ames-Kraemer Joint Venture II’s bid was $930 million.

The states and Ames-Kraemer Joint Venture II now have up to 60 days before the contract is awarded. Until then, the states cannot discuss confidential details of Ames-Kraemer Joint Venture II’s technical proposal. A public meeting will be held in early September to give an update on the project including details on the design of the new bridge.

Design-Build notice

MnDOT will use a design-build delivery method to design and construct the Blatnik Bridge replacement project. The design-build project will encompass the approach work in both states and the main bridge replacement.

The shortlist of bidding teams was released at the end of October.
