For the enclosure scope, have any standards defined whether to include the vestibule and core elements such as egress stairs, egress stair interior partitions and doors, elevator partitions and doors, elevator car and rails, shaft walls? If not, what is most common practice?
These elements are typically included in our core and shell models, so it is convenient to include. Although, so are toilet rooms, and those I think make more sense to include with interior scope.
