Adopting construction 4.0 to promote sustainability in the Mekong Delta of Vietnam: a fuzzy delphi study

This study contributes to the understanding of Construction 4.0 (C4.0) adoption in developing countries, with a specific focus on the Mekong Delta region of Vietnam. Due to a lack of innovative methods in construction, developing nations struggle to promote sustainability. To cover this research gap, prior studies have addressed the critical success factors (CSFs) and motivations but neglected the complexity and interconnections of CSFs. This study proposes a Fuzzy Delphi - Analytic Hierarchy Process analysis to discern the most influential factors for successful C4.0 adoption. The results underscore that the motivation to reduce the use of natural resources and establish an effective logistics network supersedes cost-related considerations. Collaboration, information sharing, and strategic management emerge as pivotal CSFs. This study provides valuable insights for policymakers and practitioners aiming to promote sustainable construction practices through C4.0 technology in a developing context. Graphical abstract
