More than 441 million cubic yards of concrete will be placed in 2000. And the total in-place concrete cost? A whopping $88 billion dollars. That's up almost 13% from 1999. We gathered cement and concrete statistical data from several sources. Then, with the help of the Portland Cement Association and R.S. Means, a company specializing in estimating and analyzing construction costs, we developed a methodology for estimating the total dollar value of cast-in-place concrete. We extended the methodology to estimate the amount of concrete placed in various building elements, including footings, walls, slabs on grade, columns, and elevated slabs.
