ball park estimate

ball park estimate
20 story reinforced conc tower, 1 million sf.  
ball park estimate for structural design?  my estimate just got laughed at and i am curious...

1 million s.f. x $150/sf x 0.015 = $2,250,000 for a high end fee.
for a low end use 1/2% = $750,000.
just a stab at it.  also depends a lot on the complexity of the building - underground garages?  complex facade?  high seismic/winds?  egotistical architect?

do you have a copy of the rs means building construction cost data handbook?  check out page 712 in the 2008 edition or look at the attached pdf.  perhaps this will help.   
i agree with jae.

wow, i am really surprised with the numbers. we typically end up getting 40-55 cents per square foot. you must have good architects to work with.
depending on the project, we get between 80 cents and $1.30 per sq. ft.
archeng59, the rs means can be misleading.  they lump apartment buildings with hospitals. in our state our fees would be 1.5 or so times the fees for apartments due to the scrutiny of the reviewing agency. also agree with jae, fees in the $0.75 to $1.75 per square foot.
slickdeals...  repetition figures for a lot here in reducing the design price for any highrise.

mike i think that is very true.  floor 1 - unique
floors 2-19 - all the same
roof - unique.
so in terms of detailing and gravity its almost like a 3 level structure - lateral design gets more critical and column shortening, etc. kicks in too.

yep...

jae,
are you then suggesting that $750,000 is still a good number for a low end figure?
what percentage of the architects fee's do you typically get. we target 12.5% of the architects' fee, but end up getting between 11-11.5%.
