<p class=MsoNormal><span style='color:black'>As far as the standard goes, I
think the key point here is that the baseline building evolves in the tables
and sections from the proposed building. So once the proposed building
changes, the baseline reacts. Not the other way around. <o:p></o:p></span></p>

understand that the proposed design stated in Appendix G refers to the building
