Building information modelling (BIM) implementation has been mandated in the Singapore construction industry, but it is still plagued with challenges such as lack of contractor input in design models. Thus, the industry still needs changes in the BIM implementation. This study aims to identify critical drivers for change (CDCs) towards full BIM implementation, demonstrate the theoretical rational behind the CDCs, and formulate strategies to strengthen the CDCs. Conducting a questionnaire survey with 86 professionals, this study identified 31 CDCs, among which ‘BIM vision and leadership from the management’ was ranked top. The results indicated that these CDCs could be interpreted with an adapted organizational change framework in which process-related attributes were key to changing towards full BIM implementation. The identification of the CDCs and the strategies enables the project management team to obtain sufficient support for strengthening the positive influence from the CDCs and enhancing BIM implementation. Additionally, overseas construction practitioners can use the drivers and strategies identified in this study to prepare their customized lists of drivers and strategies.
