Consultant Prequalification

Please note that prequalification is not required in order to respond to RFQs or RFPs posted on this site; but prequalification is necessary before a contract for work can be executed.

About Prequalification

What Does it Mean to be Prequalified?

A consultant will need to be prequalified by MaineDOT to perform a specific service. This entails completing an informational form, identifying the services you wish to perform, and submitting qualifications for those services. The application is reviewed by the appropriate MaineDOT program area(s) to determine whether or not a consultant is qualified to perform the service. Prequalified consultants are added to our list of prequalified consultants.

MaineDOT uses a Qualifications Based Selection (QBS) process when awarding non-construction contracts. Our list of prequalified firms forms the foundation of MaineDOT's consultant selection process when awarding contracts with State and/or Federal funding valued at $250,000 or less.

Being prequalified for service item(s) under a specific service area does not mean a consultant is prequalified to perform all work generated by MaineDOT within that service area; the project scope and the complexity of same should be taken into consideration when considering a consultant from our list of prequalified consultants.

Common Questions

Is being prequalified a guarantee of work?
No.

Does the Department still advertise Request for Proposals (RFP) for contracts valued at $250,000 or less?
Yes, MaineDOT does occasionally utilize the RFP process for these contracts.

If I am not prequalified can I still respond to an RFQ or RFP posted on this website?
Yes you can.

How does MaineDOT award contracts for projects valued at greater than $250,000?
The Department utilizes the Brooks Act (a QBS process) via an RFP or RFQ. Consultants considered for these contracts are those who have been awarded General Consultant Agreements (GCAs) through MaineDOT's Department Wide Request for Qualifications Process. When selecting consultants for contracts greater than $1,000,000 MaineDOT utilizes an RFP process.
