This book gathers the latest advances, innovations, and applications in built environment, as presented by international researchers at the 15th Built Environment Conference, held in Durban, South Africa, on September 27-28, 2021, and organized by the Association of Schools of Construction of Southern Africa (ASOCSA). The overarching theme of the conference was "Construction in 5D: Deconstruction, Digitalization, Disruption, Disaster, Development", with contributions focusing on current trends, innovations, opportunities and challenges, policies and procedures, legislation and regulations, practices and case studies, in both the public and private sectors. The volume will contribute to the existing body of knowledge relative to the science and practice of construction not only in South Africa but wherever the products of construction are produced even in these new challenging times of fear and uncertainty.
