For giant buildings this may be an issue but for the more common case of
a small or medium size site I wouldn't be too sure.  High grade, high 
quality cable can be cheaper over time since it will have less tendency to
kink or abrade and/or be less affected by such problems.  Also, if you
move or reconfigure then you never have to worry or replace the cable if
it goes from non-plenum to plenum or even exposed in floor runs.  We
recovered cable that had been run over the roof in a pipe and left for
two years.  It took a cable pulling engine to string and to remove and
when it came out it looked and acted new.  We could have bought cheaper
cable -  both times - and 'saved' money twice instead of being profligate
once and getting two runs for the price of 1.4 or so.
