Abstract:
Despite political volatility, Yemen's construction sector is gradually progressing to satisfy the country's housing needs. Most construction projects, however, employ traditional construction methods and have yet to be able to adopt sustainable construction, which is economically feasible, socially responsible, and environmentally beneficial. To support sustainable construction, this study analyzes various factors that might drive sustainable practices in construction projects in Yemen. These drivers are discovered from the literature and validated by experts using grey Delphi. Forty-four drivers were approved across three dimensions: economic, social, and environmental. These drivers are assessed using grey AHP. The economic factor is determined to be the most crucial in the adoption of sustainable construction. Competitiveness, improved well-being, and improved indoor environmental quality are rated as the top economic, social, and environmental dimensions, respectively. Overall, competitiveness is acknowledged as the most important driver for the implementation of sustainable practices in Yemen's construction projects. The study's findings were discussed with the experts who were involved in the evaluation. The findings were agreed upon, and it was underlined that a proactive approach from both construction project participants and public authorities can increase the competitiveness of sustainable construction. Additional policies to promote competitiveness of sustainable construction are also advocated.
