Consultant Prequalification

Consultants interested in providing design services to ADOT are required to be prequalified with ECS. Prequalification is done on a biennial year basis with each prequalification period beginning Jan. 1 of an even numbered year (e.g., 2012, 2014, 2016) and ending on Dec. 31 of an odd numbered year (e.g., 2013, 2015, 2017).

A new prequalification period began Jan. 1, 2014. All firms must prequalify for 2014-2015 before they can submit Statement of Qualifications (SOQ) for contracts advertised with a SOQ due date between Jan. 1, 2014, and Dec. 31, 2015.

There is no specific deadline to submit a prequalification application; however, firms should expect the prequalification process to take up to 10 business days and are encouraged to prequalify as early as possible. Consultants are encouraged to use the prequalification resources on this page to ensure a successful prequalification process.

All firms wishing to prequalify will need to provide a current ADOT UTRACS Vendor Registration Number. To get a new ADOT UTRACS registration number, update an existing ADOT UTRACS registration or search for an existing ADOT UTRACS number, go to azdot.gov/VendorRegistration.
