Project Definition & Planning/ The Common Data Environment
Project communication and data sharing are intricate and complicated, which suggests that they have to be handled in an exceedingly very structured way. Uncontrolled emailing and file sharing between project members can quickly become chaotic and impossible to trace. In the Contract Administration phase, missing a chunk of communication or referencing an outdated plan can mean wasted time, additional cost and within the worst-case scenario can cause litigation.
In the early stages of the project, communication may be between a small group of organisations: the owner, project manager and the design or construction firm. As the project progresses and specialist consultants join the team, the communication network becomes increasingly complex and unwieldy.
A centralised project room can solve much of the communication and data-sharing issues. The Common Data Environment (CDE) is a shared project domain that manages the organisation and sharing of information. The appointing party is accountable for establishing and managing the Common Data Environment for the whole project. If the project implements an outside solution, then CDE should be the first signed contract in the project. The appointing party should establish the CDE at the very start of the project.
The person responsible for keeping the information updated, secure, complete for the project is ‘Information Manager’.
The concept of the CDE, as described in ISO 19650-1 refers principally to an agreed source of information. This includes all project documentation, reports, plans and models. In this definition, the CDE is composed of four states:
- WORK IN PROGRESS (WIP)
The work in progress state is used for information while it is being developed by its originator or task team in the native authoring environment.
The shared state is used for information that has been approved for sharing with the appointing party or with other appropriate appointed parties or task teams for review, coordination and validation.
The published state is used for information that has been authorized for use, either in the construction or in the operation of an asset.
The archived state is used to hold a complete record of all containers that have been shared and published during the information management process.
Key Features and Benefits of CDE
- Document Management
The CDE provides a centralised repository for all project information for drawings, models, contracts, reports, schedules, tenders, and bid documentation.
Project communication such as mail, drawings, models, revisions, bids and tenders, contracts, RFIs, change orders are managed centrally. All communications and transactions are automatically tracked by time, user and subject.
- BIM Collaboration
Many CDE tools provide a model viewer for IFC or native formats.
- Workflow Management
Workflow management tools allow project members to create customised workflows with clear input, output and actors at defined key-stages.
- Inspections & Checklists
Field apps for mobile devices can provide the model or plans on-site, as well as creating checklists and punch lists in real-time.
- Reporting & Insights
A graphical dashboard gives a high-level overview of the project, showing outstanding tasks or a detailed report on the progress of document approval or critical issues.
- Handover to O&M
Operations and maintenance (O&M) information and as-built documentation are submitted in a standardised format directly to the CDE as the asset is being built.
