ASCE 7-10 wind loads 1

Does anyone know whether the minimum MWFRS wind loads (16psf walls / 8psf roofs) listed in 27.4.7 are ASD or LRFD? I assume LRFD, but not sure. If so, i would need to multiply by 0.6 in order to compare it to the calculated loads. Funny thing is that most local conditions produce a total load well under this miniumum, which makes the grueling calculations almost pointless. I only noticed this as i was finishing up my new spreadsheet. Awesome.

Well maybe is just here in Arizona and California.

But I have had to write letters (to clients and building departments) that the structure is okay for the higher 115/110 mph wind speed maps. I have also had to tell clients that "No you do not have to get the permit for the 90 mph wind now before it goes up. The 115 mph wind will not increase the cost of the structure."

I agree for engineers it is nothing. But I have to wonder how my clients feel about my fees to redo the calculations and write letters about it. Because I am not going to do them for free.
