    That job looks like an airport terminal.
    I'm pretty sure the Arch/Engineer have taken all wind calcs into consideration....probably over-engineered.
    So I wouldn't worry about that....just install what is specified


    What about Lightning Protection?

    So this parking garage is out in open space? Good chance it is there because there isn't room to spread all that parking space over grade level - so other structures are probably necessary to take into consideration on how they impact wind speeds.

    Pretty good chance whoever designed it took that into consideration when selecting materials - OP is asking best way to get them hoisted into position.

    OP appears to have posted a picture of an airport terminal and this lighting will act as airport apron lighting which would place it out in the open. I'll ask questions that may not seem to pertain to the original question to see about the context and provide a more well rounded answer. The reason I originally asked the question was it looked like the pole foundation detail was for an in-grade pole while OP was noting it being installed at a higher elevation and something seemed off. It's hard to tell sometimes though with grainy JPGs. With additional information provided by OP I'd agree with you that they more than likely took this into account, but never hurts to ask for more information.

    Every place has a minimum that they have to design to, here we are an 80 mph wind zone.
    I can build anything you want if you draw a picture of it on the back of a big enough check.

    There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

    I realize that, but if installing them 60 feet above ground level do you have a different wind speed then at ground level?

    No, but that wasn't the question. We only have one four story building in town and the wind once clocked out at 105 mph up there.
