Platform support for flat roof
Platform support for flat roof
(OP)
Hello,
I have a client that is wanting a small (12'x9') roof mounted aluminum platform to facilitate stack testing a couple times a year. In that past they have been using scaffolding to access the stack ports. The roof is structural steel supporting metal decking, supporting sloped insulation with a membrane cover (design roof live load = 30psf). I am attempting to locate a type of "foot" that I can use to land my square tubing platform columns on the roof, and some tie down details to anchor the structure. There are no real uplift forces, I just don't like the idea of it floating around up there.
I cannot be the first to need something similar, does anyone have any suggestions? A link to something similar: Link
Thanks,
Tom

I see from the lack of response that our best option may be to penetrate the roof membrane (round tube in order to use a standard seal boot) and land on either existing or newly placed framing members. Any lessons learned or advice for this type of support?
Thanks,
Tom

To them, this was a cheaper and easier thing to accommodate. And it provided them access as required to facilitate service/testing on their mechanical equipment.

Jayrod12 - This structure is only 6ft above the roof. My gut tells me that square pads would work because that exactly what the scaffolding they were using for years bears on. I am reluctant to sign off on it for my replacement platform due to a total lack of information on the rigid insulation.
