Reason for change:
Because the final foundation, design could not be completed until final steel building load calculations were
provided, there were some minor modifications to pier and footing sizes asoresult of the final load
calculations. The resulted in increased concrete, rebar and excavation costs. The footing rebar for the City of
Bozeman's vehicle lift was also found to be inadequate upon final review of the product specifications, which
resulted in increased psbar being placed in the footing. (CP#19) Therefore, the City of Bozeman issolely
responsible for $225inrebar.and the balance of the proposal, $11.860,54.imsplit evenly between owners.

The footing size did not change only the re-bar. It went from 240 If of #5 bar to
578 If of #4 bar. @ 68 / If we're looking at $225,00 +/-.

One thing I forgot on this is that HRDC should not pay for the Mohawk lift footing
size increase. Can you either break that value out separately (if its easy) or
estimate a percent of the total CP cost that I can use to break it out.
Thanks
Mike
