The Minnesota DOT maintains and enhances the state’s transportation infrastructure, including highways, bridges, and transit systems. For contractors, winning a MnDOT contract provides substantial revenue and a chance to contribute to critical public works projects. This guide will help you understand and navigate the qualification process for MnDOT projects.

What is MnDOT bid letting?

MnDOT bid letting refers to the formal process by which the Minnesota Department of Transportation announces upcoming transportation projects and invites contractors to submit competitive bids. The bid letting process ensures transparency and fairness in awarding contracts for infrastructure projects such as road construction, bridge maintenance, and highway improvements.

How does Minnesota DOT bid letting work?

Here’s how MnDOT’s bid letting process works:

  • Project announcement: MnDOT releases detailed information about upcoming projects, including project scope, location, timeline, and specific requirements. These projects are posted on MnDOT’s website and other platforms where contractors can access all necessary documentation.
  • Bid submission: Contractors interested in the project prepare and submit their bids, which include detailed cost estimates, proposed timelines, and plans for executing the project. Contractors must submit bids by a specific deadline and follow MnDOT’s submission guidelines closely.
  • Bid opening: MnDOT publicly opens all submitted bids on the designated bid letting date. This ensures transparency and allows for an open review process where contractors can see who is competing for the project.
  • Bid evaluation: MnDOT evaluates the bids based on several factors, including cost, contractor qualifications, experience, and compliance with project requirements. The contract is typically awarded to the lowest responsible and responsive bidder.

MnDOT schedules bid lettings on specific dates throughout the year, and contractors should regularly check MnDOT’s procurement resources for updated information on available opportunities. You’ll find the 12-month letting schedule on the Bid Letting page of the website.

Who is eligible to bid on construction projects?

To bid on MnDOT construction projects, contractors must meet several eligibility criteria to ensure they have the financial stability, experience, and resources to complete large-scale public infrastructure projects successfully. Here are some of the required qualifications for contractors bidding on MnDOT projects:

  • Register with the Minnesota Office of the Secretary of State. 
  • Provide a proposal guarantee of 5% of the bid price. You may use a bid bond.
  • Some projects require special permits or licenses.
  • Make sure you have a federal tax identification number and a Minnesota tax identification number. 
  • Do not use suspended or debarred parties as material suppliers or subcontractors on projects.

Disadvantaged Business Enterprise (DBE) Participation

In addition to the general qualifications, MnDOT actively promotes the participation of Disadvantaged Business Enterprises (DBEs), including minority-owned, women-owned, and veteran-owned businesses. The DOT encourages these businesses to bid as prime contractors or participate as subcontractors on larger projects.

MnDOT sets DBE goals on many contracts to ensure equitable participation in state projects. This provides a unique opportunity for DBE-certified businesses to grow and compete in the public sector.
