Had a vendor visit to look at installing projection in our proscenium space, and he wants to attach the motorized screen (probably about 22'W) to the underside of our arch rather than hanging from some catwalk-accessible steel just in front of the arch... What do you all think I should insist on in terms of engineering that to make sure this additional, not-originally-designed-for load doesn't bring the whole arch down? I don't know what these things weigh other than enough to hurt. I suppose spreading it over about 30 sq. ft helps.
It's a 1962 cement block wall with a new arch fascia added in later renovation. No idea what's behind that or what damage was done/covered up in the reno (generally, have reasons to not trust that anything is as it should be in the building).
Don't worry and let them do their thing? Engineer's stamp? Install whatever anchors and proof test first?
