2026 Statewide On-Call Traffic Engineering Services

Request For Proposal

Iowa Department of Transportation

Introduction

The Iowa Department of Transportation’s (Iowa DOT) Traffic Operations and Safety Bureau is

interested in entering into a professional services contract with up to three consultants to provide

traffic engineering services. If your firm is interested in providing the described services, please

submit a proposal stating your ability and availability to complete this work.

Project Background

Due to the expiration of the existing on-call traffic engineering services contract, the Iowa DOT

is seeking to negotiate and enter into a new three-year, on-call professional services contract with

three consulting firms capable of performing traffic engineering services. The work will be

located statewide.

Project Scope

The services performed by the consulting firm shall encompass and include all detail work,

materials, equipment, and supplies necessary to provide traffic engineering services. These tasks

include, but are not limited to:

• Developing and submitting plans, specifications, and estimates for highway signing,

pavement marking, and traffic signalization projects; and responding to contractor

inquiries prior to letting

• Administering highway signing, pavement marking, and traffic signalization construction

projects:

o Inspecting contractor’s work

o Documenting quantities and working days

o Reviewing shop drawings

• Conducting traffic engineering studies:

o Traffic impact studies

o Speed studies

o Traffic signal warrant analyses

o Intersection control evaluations

• Drafting polices, manuals, and design guides

Tasks will be assigned on a case-by-case basis with respect to the consultant’s experience,

expertise, and availability.

Contract Information

Negotiations with the selected consultants will commence upon notice that the selection process

is completed. The selected consultants will perform on-call agreements for three years. The

following fee payment methods may be used:

• Cost plus Fixed Fee with annually adjusted overhead payment method will be used for

larger-scale projects with durations longer than one year.

• Lump Sum for smaller-scale projects with a shorter duration.

The Iowa DOT will not guarantee the number of consultants selected, a set amount of work, or

contract value for these contracts.

General Requirements

The consultant and their subconsultants are required to meet the requirements of specified work

categories as defined in the Iowa DOT’s Policy and Procedure Manual, Policy No. 300.04, at the

time of contract execution, and for the duration of the contract. Qualifications will be assessed

during review of proposals; no prequalification submissions are necessary. Work under this

contract will require the consultant team to meet the minimum qualifications standards of work

categories:

• Traffic Operations Design (218)

• Traffic Operations Improvements Involving Construction (226)

• Traffic Control Systems Analysis, Design, and Implementation (235)

• Traffic Operations Studies (236).

Failure to meet the requirements during the contract will result in cancellation of any remaining

portion of the contract.

It is the policy of the Iowa DOT that Disadvantaged Business Enterprises (DBEs) and Targeted

Small Businesses (TSBs) shall have the maximum practicable opportunity to participate in the

performance of Iowa DOT contracts. Funding of the work under this contract is not expected to

involve federal-aid highway funds. No DBE goal (0%) is established at this time. Although a

DBE / TSB goal is not established, the Iowa DOT still encourages the spirit of the program to be

incorporated in the proposed contract whenever possible. In the event DBE participation is

required on a particular contract, the goal will be established as part of the negotiation.

Selection Information

Emphasis should be placed upon providing information concerning your proposed project

approach, similar projects your firm has recently performed and the availability and

qualifications of your key staff. The proposal may include additional information, as deemed

appropriate, subject to the overall length restriction established in Proposal Requirements.

The selection committee will review and evaluate the proposals submitted based on the

following criteria and the weighted value assigned to each. Include a detailed statement for each

evaluation criteria.

• 35% Traffic engineering qualifications and expertise of key staff

• 35% Work experience that demonstrates familiarity with traffic engineering concerns and

solutions associated with state, US, and Interstate highways in Iowa

• 20% Quality of written communication, including clarity, conciseness,

audience‑appropriate tone, accuracy in spelling and grammar, and overall presentation

that supports readability and effective visual organization.

• 10% Proximity to the project area: a permanently staffed office, or member of the project

team, physically present within the borders of Iowa

The selection committee does not anticipate the need for oral interviews.

Contacting any selection team member other than the RFP contact person is inappropriate.

Marketing meetings with the Iowa DOT while this RFP is active is also considered

inappropriate.

3. Name, qualifications, experience, and availability of the contract manager, the project

manager, and the manager of each major work task. This information should include the

contract to avoid a potential conflict of interest.
