Assessing green BIM readiness: evidence from the Vietnamese private construction firms

Purpose Green building information modeling (Green BIM) offers significant potential for advancing sustainable construction practices. However, implementing Green BIM requires construction firms to align their strategies, processes and workforce capabilities toward sustainability goals. Despite its importance, limited research has examined how ready construction firms are to adopt Green BIM. Therefore, this study aims to assess the readiness of construction firms in Vietnam to implement Green BIM. Design/methodology/approach The MIT90s framework was applied to assess five internal organizational dimensions: strategy, structure, management processes, individuals and roles and technology. A total of 241 valid responses were collected using purposive sampling. Data were analyzed using the fuzzy synthetic evaluation method to determine readiness levels across firms of different sizes. Findings The findings highlighted that firm size plays a significant role in shaping readiness. Large firms demonstrated the highest readiness, followed by medium-sized firms. Small firms showed the lowest levels across all five dimensions. The results indicated that larger firms have clearer strategies, better-defined structures and stronger technical infrastructure. In contrast, small firms faced resource, planning and workforce-capability constraints. Originality/value This study highlights that Green BIM adoption requires not only technological tools but also comprehensive organizational alignment. The research contributes to theory by validating the use of the MIT90s framework in sustainability-driven innovation. Practical implications are offered for firms, policymakers and project stakeholders to support improvements in readiness.
