In Chapter 6 we discussed both detailed and rule-of-thumb methods for quantifying rebar weights. We have not given you rebar solutions for each CIP concrete system. Using 100#/CY as an average and the summary recap Figure 11.3, what is the approximate total tonnage for our case study rebar? Using rebar unit prices from figures in these last two chapters, what is our total anticipated rebar supply cost? We will be able to use these results on bid day if we receive rebar supply quotes.
