Structural steel cost curve
Structural steel cost curve
(OP)
I've been tasked with trying to come up with an optimal span cost analysis for an owner. Typically, the architects have governed the locations of columns and beam spans, but I actually have freedom in choosing this go round. Of course, cost is the main concern. I know the larger my spans, the deeper my beams may get, but this may be offset by needing fewer columns and foundations. I also know by keeping my spans shorter that I'd be able to use shallower beams, but this would result in more columns and foundations, which could also drive up the cost.
Would any one be able to point me in the right direction to come up with some sort of cost analysis to try and come up with some sort of optimal span?
Thank you all.

If you want to do it yourself, you might want to start with the Means Structural System costs catalog.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I would second msquared48's point about not forgetting the labor, picks, etc. These affect the overall costs to a similar degree as the materials do.
