In 1989, the oklahoma department of transportation (odot) initiated the use of statistically based quality assurance and quality control (qa-qc) specifications for their highway construction projects.To facilitate the transition from the "method" specifications to the qa-qc specifications, odot contracted with the school of civil engineering at oklahoma state university to develop and conduct a series of training courses, or modules, that addressed the various aspects of construction methods, process control, and acceptance sampling and testing procedures. The progress of the odot construction quality management program, the changes that took place in the original qa-qc specifications, and the reasons behind these changes are described. An assessment of the training program is presented. This paper appears in transportation research record no. 1310, Construction innovations 1991.
