It also involves communication of large amount of information along the value chain in the execution of the project. The timeliness, accuracy and completeness of information over the various stages of the value chain is key to successful completion of the project on time and within budget. To better integrate work processes and connect stakeholders working on the same project throughout the construction and building life-cycle, there is a strong need to put in place Common Data Environment (CDE) to enable a more structured manner to create, organise and communicate information for project collaboration and life- cycle management of delivered facilities. Today, project teams often have to deal with different information requirements from different developers. This is not ideal as it would mean having to deal with different data sets and standards, making process changes within project and enterprise, and spending time understanding the information requirement specifications for each new project. Hence, the various government agencies – Housing and Development Board (HDB), JTC Corporation (JTC), Defence Science and Technology Agency (DSTA) and Building and Construction Authority (BCA) had worked together with the industry to establish the information requirements in a common data environment for projects to ensure consistency in information requirements to support the project delivery and life-cycle management of assets. 4  CDE Data Standard 2 Definition & Components of Common Data Environment (CDE) Owner/ Developer Asset/ Common FM Operator Data Consultant Environment (CDE) Contractor Fabricator Definition of Common Data Environment: Common digital space that hosts the relevant information for collaboration, exchange and communication to deliver a project. Components: CDE comprises two components – the Data Standard and the Data Platform. Data Standard defines what are the information required and how the information is structured for sharing and collaboration within a common data environment to deliver a project. Data Platform refers to the computer system or technology platform that the data and information is stored, shared and collaborated on in a CDE. CDE Data Standard Data Platform How data is structured How data is collaborated 5  CDE Data Standard 3 Objectives of CDE The Common Data Environment (CDE) aims to: Ensure consistent and better managed project information and process for projects. Allow project team members timely access to up-to-date, relevant and reliable project information in a common and structured environment for the delivery of a project. Facilitate close collaboration among project team members through sharing, exchanging, communicating and managing the project information in a common space. Enable project teams to derive useful project performance insights for trending purpose. 6  CDE Data Standard 4 CDE Framework The CDE focuses on the coordination and review states of the data and information at the shared and published states to support collaboration, information exchange and management and the project delivery process. Information Container for Collaboration Work in Shared Approved Coordination Progress Creation Authorise d Published Verified Archive Reviewed Records Based on the international standard ISO 19650: Organization and digitization of information about buildings and civil engineering works, including building information modelling (BIM) — Information management using building information modelling – Common Data Environment Workflow 7  CDE Data Standard 5 Purpose of CDE Data Standard This document focuses only on the Data Standard of the CDE and sets out the information requirements for the various digital use cases in a common data environment for projects. The data captured within the CDE can also be used to monitor the health of individual projects e.g. monitor delays and to benchmark the performance across different projects e.g. performance of contractors for different projects. Organisations can select the relevant use cases and related data requirements from this Data Standard and add on agency-specific requirements according to specific project needs. Private sector firms can also adopt the standard and manage their project information in a structured and collaborative environment.

With each activity, various Digital Use Cases have been identified and the corresponding Digital Deliverables and CDE Use Cases are also included. Project Activities may be applied at specific Project Stage or across various Project Stages, depending on the project needs and as specified by the client. The list is not exhaustive and organisations may add on project-specific activities and use cases. 11  CDE Data Standard 8.1 Definitions of Digital Use Cases and Requirements for the Deliverables and CDE Use Cases The use of a digital platform as the Common Data Environment is recommended to maximise the benefits of the Digital Use Cases. The CDE Use Cases listed here are non-exhaustive and will depend on the functionalities of the digital platform.

They contain the information required by the various stakeholders for sharing, collaboration and communication amongst the different project members to successfully deliver a project. Hence, the standardisation of the model element names and specification of the element attributes or parameters will provide better consistency and clarity in the communication of the information required between the project members. Note: Will align to ISO 16739-1:2018 Industry Foundation Classes (IFC) for Data Sharing in Construction and Facility Management Industries – Part 1: Data schema. 25  CDE Data Standard 9.1 Requirements for Model Elements, Parameters, Data Type and Units NOTES: 1. ‘Main Element’ and 'Sub-Element' names and 'Parameters' are generic terms commonly used. 2. Parameters if indicated for ‘Sub-Element’, are add-ons to those shown for the ‘Main Element’ e.g. ‘Ramp’ has an additional parameter Gradient on top of the other parameters such as Type, Description, Level/Storey etc. under ‘Main Element’ - ‘Floor’. 3. Vendors are to map the generic parameters to their respective software parameters and to add on any required parameters as new parameters if not already found in the software. 4. Software-specific element names are provided for ArchiCAD and Revit only for now.
