I am looking for the number of steel frame multi level office buildings that
are already in existence in the US and the number of multi level steel
frame office buildings that are being built every year in the US (world wide
is ok too, but US is sufficient).

It is ok if it is concrete reinforced.  

My scenerio is that I have to find a market for an invention.  The
invention surpresses floor vibrations due to walking (this is only a
problem in cheaply built steel frame building for the most part). 
Most buildings of this nature are office buildings, and since the
device I speak of is about $35,000 each, it is not realistic for any
sort of residential use.

The search does not have to be limited to office buildings, but I did
not know of any other structure that would benefit from what I
described above.  If you feel you found another category that I am not
thinking of that would benefit from what I said above, then please
include it.

I have a presentation on the 13th and this number would be really
helpful.  If i don't get the answer by then I don't think this number
will be needed.

Thanks for all your help.

If this problem only comes up in buildings that were built cheaply,
what makes you think the building owners would want to spend
$35,000.00 to correct this annoyance?

Buildings still cost much mre than $35,000.  Tradional methods for
correcting this are much more costly, not so much in price of service
performed, but in lost work time and inconvience to the tennant
(traditional method usually include a large scale reconstruction where
tennats have to vacate during reconstruction).

This is only a problem when the tennant is SO annoyed, the workers
cannot function properly because of the annoyance of the vibrating
floors - (keep in mind the building isnt going to fall down, its just
doesnt allow for a productive work environment), and this leads the
tennat to extreme measures(e.g. - refuse to pay rent, bring in
lawyers).

When the tennant gets to this point, the landlord starts bringing in
expensive consultants which usually dont have good answers.  The
landlord calls in diagnostic companies which do not fix the problem,
but merely reitterate that you have a problem.  Then the tennant
starts litigation, so then the landlord has to pay for lawyers .... 
Add it all up, and this is way more than $35,000 + all the stress
involved.

This is why some building owners would spend 35g's to fix this
problem.  I understand the price is very high right now, and that is
the ultimate road block right now.



I think i am going to cancel this question and post a new one, since i
have to zero in on problematic buildings.  I just dont know how that
is possible.

If you think you know a way to find problematic (# of buildings that
have experienced or tend to experience floor vibrations due to
walking), let me know and i wont cancel the question.

If you think you can actually do it, and get me a concrete solid
factual # of problem buildings (from floor vibrations) in the US or
world, there is a good chance I can talk to my advisor and get more
funding since I realize this is an indepth question.  Right now this
is out of my pocket and my group members pockets, so we didnt want to
go crazy becasue we never used this service before.  I think my
advisor would pay good $$$ for the answer.

I know this is tough to find, for me at least. I figured the answer
peeps would have ways to find this stuff that i wouldnt even think of.

Let me know what you think.
