Because most Revit users operate in a silo, and because they don’t understand or consider the implications of moving a level with respect to the other disciplines, some may consider it prudent to have the BIM manager control the levels instead.
Consider the HVAC design. Typically, they would use ceilings as hosts for their diffusers. If the architect has the notion of moving a level, and if the ceiling is slaved to this level. The plenum space may be reduced, and the HVAC system may disconnect and would have to be remodelled. Ultimately the client pays for this.
Someone might also forget to lock a level, then move it. Oops.
Clearly an initial educated guess would have to be made on the levels. Architectural levels typically indicate the finished floor level. Structural Levels the Top of Slab. Mechanical levels the Plenum. These can be close together and be difficult to display.
For this reason, I copy them into a model that hosts the levels and grids for all the different disciplines using the copy and monitor tool. They are then copied and/or monitored back into the discipline models.
The BEP is altered so that the level container file is the ultimate reference for any disputes and that, should someone need a new level or need to alter a level that it shall be requested of the BIM manager.
