site specific seismic assessment

[msucog]

for you structural guys/gals, can you ballpark what you think the $$$ savings would be in terms of total project cost if the site specific seismic assessment gets the maximum 20% reduction allowed by the code for the following (assuming the project is at least moderate sized):
1. if the seismic design category does not change?
2. if the seismic design category bumps up one category?

(example: the reduction saves the owner $25,000 on a $5mil project--0.5%)

thanks
