ENR publishes both a Construction Cost Index and Building Cost index that are widely used in the construction industry. This website contains an explanation of the indexes methodology and a complete history of the 20-city national average for the CCI and BCI. Both indexes have a materials and labor component. In the second issue of each month ENR publishes the CCI, BCI, materials index, skilled labor index and common labor index for 20 cities and the national average. The first issue also contains an index review of all five national indexes for the latest 14 month period.

Recession Blunts Steel Price Spike Steel prices surged to record levels during the first half of 2008. However, since then the economy has been battered by bad economic news with many economists believing we are on the cusp of a recession. As a result, steel prices have already started to retreat from last summer’s peak. ENR’s 20-city average price for channel, wide-flange and I-beams fell nearly 5% this month, marking the third consecutive monthly decline. Despite the string of price cuts, steel prices are still 13% above 2007. View Complete Construction Economics Report [Nov 24, 2008]

• Construction Cost Index History
  200 hours of common labor at the 20-city average of common labor rates, plus 25 cwt of standard structural steel shapes at the mill price prior to 1996 and the fabricated 20-city price from 1996, plus 1.128 tons of portland cement at the 20-city price, plus 1,088 board-ft of 2 x 4 lumber at the 20-city price.
• Building Cost Index History
  68.38 hours of skilled labor at the 20-city average of bricklayers, carpenters and structural ironworkers rates, plus 25 cwt of standard structural steel shapes at the mill price prior to 1996 and the fabricated 20-city price from 1996, plus 1.128 tons of portland cement at the 20-city price, plus 1,088 board-ft of 2 x 4 lumber at the 20-city price.

The building and construction cost indexes for ENR’s individual cities use the same components and weighting as those for the 20-city national indexes. The city indexes use local prices for portland cement and 2 X 4 lumber and the national average price for structural steel. The city’s BCI uses local union wages, plus fringes, for carpenters, bricklayers and iron workers. The city’s CCI uses the same union wages for laborers.
