Integrated Digital Delivery (IDD), one of the key thrusts of the Built Environment Industry Transformation Map (BEITM), is a holistic approach that uses digital technologies to connect all stakeholders involved in a construction project. It streamlines and simplifies every stage of a building’s lifecycle—from design to fabrication, construction, and asset management.

IDD Use Cases

BCA has identified several IDD use cases across the design, fabrication, construction, and asset management stages of the building lifecycle. Of these, there are 19 IDD essential use cases [PDF, 384 KB]. These use cases play a crucial role in driving greater adoption of IDD and collaboration among project stakeholders. They also demonstrate the benefits of adopting IDD for streamlining construction project stages. 

Getting Started with IDD Implementation

Whether your organisation is new to IDD or wants to improve current practices, the resources below can help. They offer clear steps and useful tips for planning and carrying out your projects.

Note: Organisations requiring IDD professional services can refer to the Shared Services Provider (SSP) Programme administered by the Specialists Trade Alliance of Singapore (STAS) for the list of registered providers.

Resources and Tools

To truly achieve successful IDD implementation, your organisation and project teams will also need to focus on developing quality BIM models and establishing robust data management practices – these form the foundation for unlocking IDD’s full potential and ensuring smooth collaboration across all your projects.
