Thanks for the reply. I like that idea of the welcome packet that goes beyond just the mission statement/artistic vision blurb.
They haven't given a reason for not sharing, which I find perplexing. As you said- I also wouldn't expect a show RA, as the peculiarities of the set/installation will be specific to my project- but their fire evacuation plan, features and attributes of their building, house rig, weight limits, etc would surely have to come from them- not me completing a visit, or having to work out safe working loads based on the truss type, chain hoist data of the house equipment- that seems like something they should be able to provide to me as a document upfront.
