The
Arizona Department of Transportation (ADOT) relies heavily on engineering
consultants to design, develop, and manage highway projects, and on contractors
to build and maintain the roads, bridges, and landscaping. ADOT should evaluate
its use of consultants and optimize internal resources to reduce consultant
usage. ADOT should improve inspection consistency, documentation, and follow-up
to help ensure compliance with construction standards. ADOT should also address
its backlog of consultant and construction audits to help ensure that contract
payments are proper.
