I've done a lot of 50' stages with underhung rigging but all new build in last 10-15 years which all include a means to get to the rigging over the stage. At 50', I prefer catwalks, as illustrated in this article: http://www.lightingandsoundamerica.com/mailing/PLASAProtocol/PWinter14_StageHeight.pdf The 22" wide catwalks 8' on center typically allow three shell ceiling panels and the 4th electric to store under then with a high trim in the 35-40' range, while the rest of the rigging has a high trim in the 44'-45' range - enough for a lot of rental drops and to fully fly curtains. With a trip up a stair, maybe some ladder, you are within arms reach of every part of the rigging. I put a high value on that. Now I'm being asked (by the architect for budget) to forego the catwalks, so rigging is hanging there 50' in the air with no easy way to inspect and service it. I'd estimate those typically 4 catwalks at $40,000-50,000 in what is probably a $10-12m project. Just for perspective, I'm thinking about walking away from a project that represents a fourth or fifth of my income for a year. I just wonder if I value this access to rigging too highly, and should say sure, but plan on renting a big scissor lift once a year for annual inspection plus whenever service is needed between. (Ofcourse they won't if like most schools, and it will never be inspected. That is what happens.) Please share your thoughts and comments, with my thanks in advance.
