Construction Materials Estimating Values 1

[BubbaJ]

While reviewing for the SE II Exam, I noticed one question involved construction economics, ie. what is the approximate cost of the two slab scenarios designed (one composite, one not.) Due to all the destruction and construction lately, I've had a difficult time keeping up with costs. Can anyone give me some reasonable values for placed reinforced concrete, steel, joists, wood, shear studs, basically whatever you've got. I'm in the Midwest, but I don't know if that is relevant since this is a national exam.

Thanks.

I would check RS Means Construction Cost Estimating Guides or your local DOT for historical bid data.

In Ohio, ODOT has historical bid data here

http://www.dot.state.oh.us/contract/estimating/CIS/Construction Item Surveys.htm

from 2004 and other past years. Of course you need to know what the items are (see the ODOT construction and material specifications here (

http://www.dot.state.oh.us/construction/OCA/Specs/2005CMS/2005_ODOT_C&MS.htm),

but you should be able to get some decent numbers for concrete, steel, shear studs, etc.

Off the top of my head I would say, in general, placed concrete = $400/cy, steel installed = $1.50/lb. Not sure about other items.

Hope this helps.
