Enhancing Decision-Making and Sustainability in Building Product Selection and Circular Economy Implementation in Construction

Abstract

This research examines the selection and specification processes of building products and their implications for design managers. It identifies the conservative nature of specifiers in adopting new products, influenced by time constraints and risk aversion. Through a combination of ethnographic observations, surveys, and interviews, the study highlights inefficiencies and challenges within design offices, such as the reliance on familiar products, inadequate management systems, and limited knowledge-sharing practices. The findings underscore the need for better management of the specification process, emphasizing the importance of balancing constructability, cost, and innovation. The paper also sheds light on the growing influence of manufacturers in the decision-making process and proposes strategies for design managers to enhance specification practices and project outcomes.
