Hi Josh. I have had the privilege of managing my current facility for 15 years now. I came on board for the last several months of the construction process,a nd have been on ever since. I have also consulted on 6 other facilities; all for seconday schools or colleges. I'd be happy to speak with you. Feel free to email me Dsimpson@ecsd.us.I also second Controlbooth.com. I have been a moderator there for years. It is a great resource.
There are many experienced Theatre Consultants that follow this web site, myself included, and we would all love to get involved with your projects, however, before that can happen you need to develop trust and understanding with your administration so they will listen to you when you ask them to involve a Theatre Consultant and Acoustician. These skill sets are hard to come by and require lots of experience not just in theatre, but in understanding the construction process and how all the other building systems evolve in a design.
Good consultants can guide your design team so they create a space that is sensitive to the arts and not "just another school building". Theatres and their surrounding support spaces have very unique requirements to make them functional for the users while still satisfying the necessary building codes. Most architects and engineers just don't 'get' theatre and as result they sometimes listen to product manufacturers for (biased) advice rather than having systems designed for the unique needs of your facility. An independent consultant can bring the needs you have together with knowledge of a vast array of technologies to get you a well defined construction package that your school district can get competitively bid. They also provide oversight of the shop drawings and installation work to see that the owner is actually getting what they paid for.
You are correct, the list you started is just an inkling if what is to come. Although the broad definitions of what you need are important, and are a great first step, the reality is that "the devil is in the details". Lots of details. Understanding how to define the infrastructure needed to support good theatre and good theatre systems is a key part of what we bring to the table.
One of the most overlooked aspects of planning is sometimes the site selection for a venue. This is determining where the building sits relative to the surrounding buildings and how both the audience and the staff / crew / roadshow truck(s) will access it. A land-locked stage is a miserable place to try to load a show into. And a theatre lobby buried in the mass of a larger building can be difficult to find and uninviting to the visiting audience.
Please feel free to reach out to the professionals in the community as we are all interested in your project and your business. The fear of hiring someone from out of town should be cast aside, as we are all experienced travelers and can keep expenses to a minimum. Most of use work on more projects far outside of our hometown than we do nearby --- and this is a good thing, as it give us a broader perspective as to how the theatre world is evolving so we can bring that knowledge back to your project(s).
