Certification programs fit into two main categories: plant certification and personal certification. Prestressed, precast, and ready mixed concrete producer associations have established programs requiring thorough inspections of production facilities. The inspections are conducted by impartial, professional engineers who are qualified to certify that the plants have properly calibrated and maintained equipment that can produce and deliver concrete and concrete products that meet industry standards and project specifications.
Programs setting performance standards for certifying individuals have been developed by industry organizations, and by some state trade associations in cooperation with universities and transportation agencies. These programs not only identify individuals who have demonstrated competence, they also serve as vehicles for providing recognition for those who acquire and maintain expertise in critical positions. Some of the ACI certification programs: Concrete Field Testing Technician, Concrete Laboratory Testing Technician, Concrete Construction Inspector, Concrete Flatwork Finisher, and Concrete Flatwork Technician.
