The BCF format aims at simplifying the collaboration process between the different team and project members working on the same model by allowing them to raise issues, provide solutions and comments in an open format that does not contain model elements.
The BCF is therefore an interchange format that is not used to exchange geometric information but simple graphical/descriptive info capable of illustrating which issues need to be addressed and solved.
Adding specific exchange notes, comments, reports, images during the management of a BIM project with a BIM management platform such as usBIM offers further advantages in terms of coordination and integration of activities.
Each BCF file "records" who, and when a comment was added during the planning and execution phases. The exchange of comments between the team members, in addition to indicating date and time references and the author, and therefore an exact cronology of status changes, is supported by using .PNG snapshots that locate the problem within the project.
