[Phys-l] Vibration Isolation Specifications



All-
We're entering the final design throes for our new/renovated science complex. The architects' attention is turning from laying out spaces and rooms to details like where the outlets go.

I'm at a disadvantage because I'm a theorist designing spaces for experimentalists to be hired once the complex is complete. I have consulted with many experimentalist friends and gotten some very helpful, concrete advice. That's the quest I am on again now.

In question are an optics lab and two faculty research labs. It remains to be seen what their areas of specialization may be, and therefore I am designing them to be as flexible as possible.

The architect wants some numbers (tolerances) for vibration isolation in those rooms. These labs will be in the basement on the slab, but will be on the same floor not too distant from the building's machine rooms. While very sensitive experiments will of course require their own vibration isolation, I don't want the optics lab (for example) vibrating away every time the fans fire up. Ideally, I'd like those labs on a separate slab. (I don't know the underlying geology yet.)

Anyone have reasonable baseline numbers for vibration limits over a reasonable range of frequencies for such labs? Or know of a source for such limits?

Thanks,
David Craig
