Integrated Digital Delivery: Implementation status and project performance in the Singapore construction industry

Integrated Digital Delivery (IDD) was launched to transform the approach to construction through the implementation of digital technologies. Whilst technologies have the potential to improve project performance, there are limited studies on IDD in the context of the construction industry. Hence, this study investigates the level of IDD implementation and the perceived improvements on project performance. Based on the literature review, 32 digital and cloud technologies have been identified and formed the basis for a structured survey questionnaire, which was distributed to target respondents covering the major roles of the construction industry in Singapore. The responses were analyzed to determine the existing level of IDD implementation and the perceived improvements in project performance contributed by IDD implementation, followed by post-survey interviews to validate the findings from the survey. The study found that only 38.71% of the organizations implemented IDD technologies in all four IDD phases. BIM, prefabrication, BIM-to-field mobile applications and building management system were the most frequently used technologies in the four phases respectively. The respondents largely agreed that IDD implementation improved overall project, project cost, project quality and project schedule performance. The findings from this study provide better understanding of the existing level of IDD implementation and the perceived improvements in project performance, serving as a starting point for future research on increasing IDD implementation.
