Too Much Weight?

[clipperfish]

Jaws . One of my Clients is a structional engineer. He tells me that all condo and apartment (that are made of wood even with 2 inches of concrete for sound proofing) .rate at 40lbs constant. And all concrete buildings are 50 lbs constant. He told me that the way my stand is built it should not be put on the second the second floor ,Because i have only six 2x4 for legs , he said if i was to put in more 2x4 I can move up to the second floor because that would lower the amount of weight that is being put down on the floor per sq. ft. Hope this helps some .
