The N.C. Turnpike Authority advertises all requests for private engineering or consulting services in the North Carolina Purchase Directory and posts the advertisements on Connect NCDOT, the N.C. Department of Transportation's website for online collaboration and resources for business, professional and working partners.
Firms responding to a request for qualifications must be pre-qualified to perform the work and listed on the NCDOT Register of Qualified Firms.
The Turnpike Authority does maintain an independent register of qualified private engineering or consulting firms but relies on the register compiled and maintained by NCDOT.
