IDD Requirements

IDD Requirements

Projects applying for Government Land Sales (GLS) sites and Built Environment Transformation Gross Floor Area Incentive Scheme shall comply with the following IDD requirements:  

    1. Formulate Integrated Digital Delivery Implementation Plan for project delivery;

    2. Adopt a minimum of five (5) IDD essential use cases across the Design, Fabrication,
        and Construction stages of project life-cycle with at least one (1) use case per stage
        for residential developments;

    3. Adopt a minimum of five (5) IDD essential use cases across the Design, Fabrication, Construction,
         and Asset Management stages of project life-cycle with at least one (1) use case per stage
         for industrial and commercial developments;

    4. Adopt the use of digital platform(s) based on the Common Data Environment (CDE) Data Standard
        to manage the IDD essential use cases across the project life-cycle;

    5. Submit a final report comprising achievements of IDD essential use cases and a list of firms
          that have participated in the use cases.

    6. Submit the first IDD activity log before the commencement of super-structural works and at
        every six-month intervals thereafter;

Please contact Skye Zhao (skye_zhao@bca.gov.sg) or Khine Wa (khine_wa_thein@bca.gov.sg) for any clarification.  

BIM Handover - Releasing BIM as part of Contract Documents

Incorporating BIM as part of Contract Documents in addition to a set of 2D drawings for construction tender enables:

  • consultants to reduce effort in 2D drawings production and clarification of discrepancy,
  • contractors to reduce effort in recreating BIM from 2D drawings,
  • clients to expect lesser reworks and delay due to undetected discrepancy, and
  • project stakeholders to rely on BIM as the Single Source of Truth for collaboration. 


The BIM Handover Technical Guide establishes the Essential Model Content and 2D Drawings which form part of Contract Documents and provides a set of guidelines for BIM preparation and issuance at construction tender. It allows clients to adjust the exact scope to suit specific project needs and forms of contracts.

Download the BIM Handover Technical Guide here.

In addition, we have worked together with GPEs, leading industry firms and practitioners to develop sample BIM handover clauses to assist all developers to stipulate the necessary requirements clearly in both consultancy agreements and construction contracts to enable BIM as part of Contract Documents.

CDE Data Standard

The successful management of timely, accurate and complete information based on a set of data standards can affect a project’s outcome. 

    1.  A Common Data Environment allows project teams to create, organise and share information
          to foster collaboration, make timely decisions and take early interventions during the project’s
          delivery and building maintenance lifecycle. 

    2. Data Standards specify what information is required for a building project and how it can be
         structured to facilitate sharing and collaboration among project team members using a
         Common Data Environment.

    3. The Emerging Stronger Taskforce (‘EST’)’s Alliance for Action (‘AfA’) on Digitalising Built
          Environment has identified these data standards as a key to accelerate digitalisation in the
          value chain.

Model Content Requirements

The Model Content Requirements (MCR) stipulates the information requirements for Building Information Modelling (BIM) by building typology as part of project information deliverables according to project delivery stages.

Incorporating Model Content Requirements establishes:

    1. Standardised project data to be captured in BIM to avoid mis-interpretation of the requirements
        by project stakeholders;

    2. Coordinated information requirements so that models prepared would enable effective collaboration
        between stakeholders across the project lifecycle; and

    3. Essential data needed to be provided at specific stage of the project to improves efficiency of model
        preparation effort to meet the information requirements in stages

Digitalising Built Environment Alliance for Actions (AfA)

The Digitalising Built Environment Alliance for Action (AfA), led by Mr Lim Ming Yan, Chairman of the Singapore Business Federation, was convened in June 2020 under the Emerging Stronger Taskforce (EST) to accelerate digitalisation of our built environment sector, and emerge stronger from the COVID-19 pandemic. The AfA will focus on two work-streams:

    1. Establishing industry-wide CDE Data Standards, and;

    2. Securing the commitment of 300 industry firms to adopt interoperable digital platforms based on
         the established Data Standard.

IDD Essential Use Cases

Based on current IDD projects, BCA has identified 14 commonly adopted IDD use cases across the design, construction, fabrication and asset management stages of the building lifecycle. Projects new to IDD could choose from these set of essential use cases to jumpstart their IDD adoption.
