That was my point, Marcel.

It's all about liability. If a trustural guy makes the call, and is good. No problem.

If he makes the call and is wrong, it's his liability.

If it even appears that someone on this board made the call (and I didn't see any posts from "qualified", meaning willing and able to take the liability, if they are wrong!) then they are left holding the bag when the place collapses. Furthermore, NACHI can also be held liable (stranger legal things have happened, MANY TIMES!).

Recommend evaluation by a licensed and insured structural engineer.

Hope this helps;

I think Richard is an engineer.

All that is necessary is to adjust the legs on the table to make the surface level in order to allow the balls to travel in a straight line. You guys are way overthinking this crap. If the enginneering is improper or incorrect it only means the legs will require more frequent (daily) adjustment. Eventually, everything will end up being leveled out. Call an engineer.

Richard isn't an engineer, but he is an architect who is familiar with residential structure. However, as a few have pointed out, answers to questions of this type cannot be given in forums such as this. Why not? Becasue the responder cannot see all the existing conditions which would enter into an evaluation, and cannot be certain that the information provided by the questioner is complete or accurate. To try to respond to a question such as this is dangerous, foolhardy, and, I believe, unethical, in the sense that it is providing, for free, that from which design professionals earn their living, and providing it without full and complete knowledge of the conditions that may affect the answer. All of that does not even begin to involve the difficulties related to assuming liability, which is also a huge concern. I, for one, feel I would be risking my professional license if I tried to answer such questions, and it seems like many here agree with me.

To get an answer to the original question might involve an hour or two of a qualified design professional's time, if that. I frequently do such things gratis, when I can examine the building first-hand. I would rather people ask me and get an answer free of charge than see them risk doing it themselves, perhaps incorrectly. But only when I can SEE what's involved.

Worth repeating and well said Richard.
