Integrating worker health and safety into sustainable design and construction: Designer and constructor perspectives

Sustainable building design and construction is gaining rapid growth within the architecture, engineering, and construction (AEC) industry as a substantial opportunity to improve the efficiency of building projects by incorporating efficient and effective materials, technologies, and strategies into the building process. However, these approaches have been found to be associated with negative potential impact on the health and safety of field personnel. Prevention through Design (PtD) strategies are well-suited to prevent potential construction hazards in green jobs. The aim of this study is to examine the perception of construction industry professionals about incorporating PtD practices into sustainable design and construction. To gauge the perception of professionals, a survey questionnaire was developed and distributed to two construction industry groups (designers and constructors). The present study contributes to the body of knowledge by providing evidence of the level of viability and extent of implementation of PtD practices into sustainable design and construction as well as identifying prevailing barriers and potential enablers of PtD implementation in the AEC industry. The findings of this research indicate that a majority of construction industry professionals, especially designers, are resistant to the implementation of PtD practices into sustainable projects at this point in time. Fear of liability, contractual methods, and lack of safety knowledge were found to be the most prevailing barriers to the acceptance of PtD practices within the AEC industry. By contrast, ethics was regarded as the primary potential enabler for the implementation of PtD practice within the AEC industry. The authors recommend that the AEC industry move further toward collaborative project delivery methods. This transformation can facilitate a wider implementation of PtD practices within the AEC industry, especially in sustainable design and construction.
