What is meant by 'convention' in the context of BIM?

In the context of Building Information Modeling (BIM), 'convention' refers to a set of standardized practices and procedures that govern the content of models. These conventions ensure consistency and interoperability among various stakeholders and across different software platforms. By adhering to specific technical practices, team members can accurately represent building elements, systems, and data, which facilitates better collaboration, reduces errors, and improves the overall quality of the model.

Using established conventions helps in creating models that are not only robust but also align with industry standards, making it easier for architects, engineers, contractors, and other participants in the construction process to work together effectively. This shared understanding of model content allows for seamless integration of diverse inputs, promoting efficient project delivery and enhanced communication throughout the lifecycle of a building project.
