The Vancouver (B.C.) Advanced Light Rapid Transit System (ALRT) has been selected as an example of a comprehensive transportation construction project where Quality Assurance played a major role. The primary aspects of a Q.A. philosophy, and its interrelationships with other design and construction requirements, are summarized. Discussion of the methodology of Q.A. for the ALRT links these conceptual ideas to the actual design and construction of the guideway system. The precast concrete beam manufacturing process, and the interfacing of Quality Control and Quality Assurance functions during beam manufacture, provide examples of a systematic approach to review, monitoring and recording all significant factors. The paper concludes with reference to the need for appropriate allocation of responsibility to attain desired results, and the delegation of the necessary authority to achieve those results.
