Construction and Materials

The Construction and Materials Group provides support to help districts with managing their construction projects. This includes providing construction administrative services to supplement the workforce with temporary technicians, construction administrative services and material testing assistance; conducting independent review of workmanship, materials and documentation; providing training for construction and lab technicians; maintaining instructional guides for construction methods and procedures; providing the services of a registered landscape architect; and processing monthly pay estimates, quantity documentation and subcontractor approvals.

The group also consists of central and regional laboratories. They maintain AASHTO accreditation for the state and provide materials-related technical support; conduct research into construction materials and methods; develop test methods and specifications; and perform testing of soils and aggregates, asphaltic concrete, asphalt binder, concrete, cement, steel and other structural materials. The regional labs are responsible for monitoring the tests performed by project labs and for conducting independent assurance and correlation testing in an effort to maintain uniform testing procedures statewide.

Structural Materials Testing

Recording and storing results of concrete cylinder testing performed during road construction is a function of numerous construction offices throughout the state. Through a number of computer applications, these testing results are captured, stored, and regularly utilized internally. This information is provided for the general public as well as current and potential vendors wishing to do business with ADOT.

Technician Certification
The purpose of technician certification through ATTI is to ensure that the technician can demonstrate competency in appropriate Arizona and AASHTO test procedures through actual demonstration of test procedures, written examination and required calculations.
