Hi Gang,

We are looking for a civil/structural engineering firm that has expertise in
roof-top tower installations.  Does anyone have any recommendations, or
suggestions where to look (maybe an industry organization in broadcasting or
commercial wireless?)

We are currently working with two engineering firms that are giving us
widely varying opinions on our proposed roof-top installations.  In
particular, one is telling us that a 40 ft guyed tower (base at 60 ft) will
generate 10+ kips of axial load (40 MPH, 1 in radial ice) and that our
W16x26 I-beam based roof structure will only support 2 kips of axial load.
These firms admittedly do not have any experience with our particular type
of installation.  Also, we have received many skeptical comments about these
results, so we are seeking a second opinion.

Thanks for any pointers.

73, Chris KA8WFC
