Dear Consultant:

The Missouri Highways and Transportation Commission is requesting the services of a consulting

engineering firm to perform the described professional services for the project included on the attached list.

If your firm would like to be considered for these consulting services, you may express your interest by

responding to the appropriate office, which is indicated on the attachments. Limit your letter of interest to no

more than four pages. This letter should include a statement to indicate your firm’s understanding of the

project. It should also include any other information which might help us in the selection process, including

key personnel you would assign to the project and the backgrounds of those individuals, and any sub-

consultants you would propose to use, and an indication of your firm’s approach to promoting and

developing a diverse workforce. MoDOT is committed to reflecting the diversity of the communities we

serve and we expect our partners to do the same. We will utilize the consultant information already on file

so we will not need a lengthy submittal of other general company information. In addition, please attach one

page with detailed information on similar projects that your key personnel have worked on. Indicate the role

your key personnel played in the projects and include reference contact information.

DBE firms must be certified by the Missouri Department of Transportation in order to be counted as

participation towards an established DBE Goal. We encourage DBE firms to submit letters of interest as

prime consultants for any projects they feel can be managed by their firm. We also encourage both DBE

firms and non-DBE firms to consider joining MoDOT’s Mentor/Protégé program whenever possible as part

of a MoDOT project.

MoDOT will evaluate firms based on: Project Understanding & Innovation, Past Performance,

Qualifications of Personnel Assigned, General Experience of Firm, Familiarity/Capability, Accessibility of

Firm & Staff. Firm’s not providing a response on approach to workforce diversity will be considered non-

responsive to this solicitation. Firm’s that are not current on all of the required prequalification categories

found in MoDOT’s Approved Consultant Prequalification List at the date of the solicitation expiration will

be considered non-responsive.

We request all letters be received by 3:00 pm, April 24, 2026 at the following email address:

order. Such analysis may include potential interstate ramp closure(s) and if the closure(s)

could be accommodated with other movements.

x Produce Road Safety Study/Audit report with recommended solutions, conceptual design and

conceptual construction estimate for MoDOT approval. The recommended solutions will

include long-term, mid-term and short-term recommendations.

x Identify, analyze and recommend mitigation for risk items especially analysis of

environmental, utility, right of way or railroad impacts.

additional consultant responsibilities to perform for remaining interchanges once programmed for

construction:

x Produce a Conceptual Study Report and Conceptual Cost Estimate.

x Work with MoDOT and FHWA to determine if recommended safety solutions will result in
