What is BIM Collaboration Format (BCF)?

The construction industry involves many trades working together towards a shared vision.

Architecture, Structural, CIVIL, & MEP trades alongside landscape architecture, prefabricators; all these function in a Common Data Environment.

Teams also call it a ‘BIM environment’ where engineers from various disciplines share files, update each other, assign reworks, etc.

Therefore, the data that is being transferred in this process is very delicate, and its accuracy and consistency make a significant difference.

To address this concern, the BIM Collaboration Format provides a standardized way to share information across different software platforms. It is an international openBIM standard, and the buildingsSMART International maintains it.

However, Solibri and Tekla were the first to introduce it in 2009.

What does BCF contain?

In practice, BCF helps the construction industry overcome communication barriers and facilitates interdisciplinary collaboration.

Most construction projects fail, or deliverables get delayed due to inconsistent data exchange and a lack of documentation. BCF serves as the communication layer for discussing the 3D building model.

BIM Collaboration Format solves this. BCF organizes key information into a standardized framework and file format. BCF can reference up to 1000 components in a markup

This gives a universally understood framework in BIM projects that reduces errors and miscommunications through BIM collaboration tools.

All stakeholders involved share the BCF file as models from various disciplines, document clash reports, and track change orders equally.

How the BIM Collaboration Format Improves Collaboration?

Since construction processes involve multiple disciplines, there is a lot of mess. BCF brings peace to the process by standardizing data from various sources.

For example,  in a project, there are 10 professionals from different disciplines assigned to work on a project.

Think of it this way- in a project, there are 10 professionals from different disciplines assigned to work on a project.

Professional 1 is an architect who finds that a structural column interferes with a particular window placement. He raises the issue with Professional 4, who is a structural engineer.

However, the structural model elements engineer works from an old drawing. Meanwhile, in the MEP BIM model, there is already a duct going through the same space.

What we get is that everyone in the room is working on different versions of the same story. They have different understandings of the same building design. BCF supports both cloud and file-based workflows for flexibility in communication.

Hence, decisions made by one team probably do not align with those of other teams. Hence, a common digital language like BCF is required here, which is an important aspect.

When it is implemented across all disciplines, communication becomes smooth with various BIM tools. From file sharing to documenting revisions and change orders from clients, everyone has the latest updates.

Here is a list of benefits as well for implementing BCF.

Benefits of BIM Collaboration Format

• Reduced errors: Implementing a standardized process, with proper BIM software tools, eliminates legacy issues like teams referring to outdated drawings. BCF preserves the integrity of the master BIM files during issue discussions.
• Enhance coordination: BIM coordination is a critical aspect of every construction project. The process that ensures all trades are aligned and the design is constructible in real life.
• With BCF, stakeholders view issues and changes in the design context from a single lens. Hence, communicating any conflicts or new ideas becomes easy sharing.
• Increased efficiency: When sharing information happens with clarity, decisions get locked faster. This helps teams keep the project on project timelines and budget. BCF improves accountability by logging a transparent history for each issue.

Beyond these benefits, a construction professional should also be aware of the use cases of BCF. Here are some of the common ones.

How can you use the BIM Collaboration Format?

Apart from providing a common digital language, BCF creates a collaborative environment where it can be used. Professionals collaborate on various agendas in the environment.

Use case: Clash Resolution

For example, a routine model review reveals a clash between the structural beam and HVAC ductwork.

The software identifies the clash and creates an issue tracking its location. The category, in this case ‘Clash Detection,’ and both the structural and HVAC teams take up the work.

BCF allows these teams to communicate on resolving this issue, and even attach revised sketches/documents. Upon resolution, it is updated as closed and documented for future reference.

Use Case: Model-Based Communication

Construction projects are never out of surprises. A small undocumented change can give multiple connected reworks or constructability issues.

However, firms that implement this openBIM standard can pinpoint model areas with issues. It is a faster way that’s only possible in a connected environment. The marked locations also allow comments from relevant teams.

They can give responses through text, links, and snaps, sharing information with a clearer context. This approach reduces the ambiguities that occur due to inconsistent information.

Final Thoughts

BIM Collaboration Format is the openBIM standard that provides a common digital framework for communication. It works with multiple software applications and facilitates information exchange across every project stage. If you are also looking to implement BCF across your construction workflows, consult with a professional team.
