Problem: When three theaters share a full suite of backstage facilities, bad planning will result in terrible conflicts.
Discussion: There are 3 basic categories of backstage facilities that will serve the two existing theaters plus the new theater:
Within each category are areas that may overlap with another area. For example, the scene shop needs an area for painting. The costume shop needs an area for dying with very similar needs. It's quite possible that these two functions could overlap or be combined, even if they "belong" to separate categories. But because of the structure of the technical theater staff, cooperation between categories will need to be arranged, not taken for granted.
Within each of these categories there is a basic need for instruction, which may or may not occur within these spaces, and for production, which will occur in these spaces.
It is essential that these three categories are equally supported, and that they can do their work without conflicting with people from another category. In addition, during productions it is equally important to avoid conflicts between the backstage support for one theater and another. It should be assumed that any two theaters may be in operation simultaneously [is this true? Even Pocket and Robinson?]
Solution: Provide a rational circulation system that prevents conflicts and allows convenient access from all backstage areas to all production areas without disturbing other productions as needed.
