In this paper, the author emphasizes the need to use a systems approach to solve complex durability problems, and, to incorporate a durability subsystem within the quality assurance system.
The purpose of this approach is to continuously improve design, specifications, construction, and maintenance.
Based on case histories of performance of sidewalks, pavements, and elevated structures, the author discusses problems linked with a few elements of such a subsystem and concludes on the need to develop design methods for durability, realistic specifications, meaningful durability tests, and rational methods for assessment of durability. Furthermore, the need to integrate the activities of all quality responsible agencies into a single managerial effective quality assurance system is stressed.
