Exploring the Transformative Impact of Integrated Digital Delivery on the Built Environment: A Case Study of Additions and Alterations Project in Singapore

This study aims to investigate the value creation and paradigm shift brought by Integrated Digital Delivery (IDD) in the built environment. The focus of the study is on the implementation of IDD in Additions and Alternations (A&A) projects, using a case study of the conversion of a retail mall into a leasable office space for banking and medical operations in Singapore. The study examines the perception of IDD by project stakeholders, the benefits of IDD in A&A projects, and the barriers to IDD implementation. Results indicate that IDD implementation in A&A projects leads to improved time, cost, and quality, better design outcomes, and enhanced design coordination. The key obstacles to IDD implementation are the lack of IDD requirements, skilled IDD manpower, IDD-ready solution providers, and higher initial expenditures. This research adds to the existing body of knowledge on IDD in the built environment and highlights the importance of IDD for value creation and paradigm shift in the industry.
