BIM is not just about creating 3D models. An effective BIM project requires a well-defined information management workflow, from identifying requirements and coordinating design to exchanging data, construction delivery, and operations.
Depending on the project's objectives, BIM workflows can be organized in different ways. Among them, six key workflows help manage information and connect different stages throughout the project lifecycle.
Requirements-Driven BIM starts with the information requirements of the organization, project, asset, or information exchange process.
Instead of creating a model first and determining what data is needed later, this workflow starts with three key questions: What information is needed, what decision will it support, and when is it required?
The workflow can include: Define Need → Specify Information → Plan Delivery → Verify Output
Requirements for geometry, data, and documentation are defined before authoring begins.
This helps BIM teams understand exactly what level of information needs to be created, avoiding overly detailed models that provide little practical value.
A Common Data Environment (CDE) plays a central role in managing project information containers.
A typical CDE workflow can follow: Work in Progress → Shared → Published → Archived. Each status has its own purpose, access permissions, and information control process.
A CDE helps manage naming, metadata, revisions, status, and suitability of project information.
More importantly, it provides traceability—making it possible to identify who created, reviewed, approved, or issued information and which version is currently being used.
This is particularly important for projects involving multiple stakeholders and large volumes of information.
In real-world projects, different stakeholders may use different BIM software platforms. Therefore, interoperability is essential for maintaining a consistent flow of information throughout the project.
OpenBIM promotes the use of open standards such as IFC to exchange data between different platforms.
An OpenBIM workflow can combine:
This means information is not only exchanged but can also be validated against defined requirements before being used.
In a typical project, Architecture, Structure, and MEP models are often developed by different teams.
Federated BIM allows teams to combine discipline-specific models into a shared coordination environment while maintaining the ownership and responsibilities of each discipline.
For example: Architecture + Structure + MEP → Federated Review
After federating the models, BIM teams can perform: Clash Detection → Review → Issue → Resolution
Coordination decisions and Issue resolution can also be recorded to create a traceable coordination history. BCF can be used to exchange Issues between software platforms without having to resend the entire model.
Construction Delivery BIM brings model information into actual construction activities.
The workflow can combine: 4D Sequence → 5D Cost Control → Logistics → Field Delivery. The BIM model is therefore not only used for visualization but can also support planning, cost control, and construction logistics.
BIM can be combined with Reality Capture, Safety Information, and Field Verification to compare design information with actual site conditions.
When BIM information is connected to construction decisions, the model becomes part of the construction delivery process, rather than simply serving as a design document.
BIM does not end when construction is completed.
Asset Information BIM focuses on transferring verified and required information from the project stage into systems used to manage the completed asset.
The workflow can be represented as: Project Information Model → Verification → Asset Information Model → Operations
BIM information can support:
When asset information is properly structured and verified during handover, operators can continue using the project data instead of having to rebuild information after completion.
The key point is that these six BIM workflows do not have to be used independently.
A project can begin with Requirements-Driven BIM, then use a CDE to control information, OpenBIM to exchange data, and Federated BIM to coordinate different disciplines.
During construction, the information can continue to support Construction Delivery BIM, before being transferred into Asset Information BIM for operations.
The overall process can be represented as: Requirements → Information Management → Interoperability → Coordination → Construction → Operations
This approach allows BIM to become a lifecycle information management system, rather than simply a process for creating 3D models.
BIM Workflow is not just about how models are created and coordinated. It is about how information is defined, controlled, exchanged, verified, and used throughout each stage of a project.
The six key workflows include: Requirements-Driven BIM → CDE-Controlled BIM → OpenBIM Interoperability → Federated Coordination BIM → Construction Delivery BIM → Asset Information BIM
When properly designed, these workflows help projects improve information control, enhance coordination, and create greater value from BIM throughout the building lifecycle.
