Construction Economics
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.

Construction Economics, Materials Trends, Cement, Concrete, AggregatesRevision drives down ENR's cement prices.

ENR's 20-city average price for portland cement fell 2.0% this month, following April's 1.7% drop. This May's decline, combined with a 0.8% increase during the same month of last year, helped to drop the annual escalation rate to 0.5% from 1.5% the previous month. The Bureau of Labor Statistics producer price index for cement (right) rose 0.2% in March, after holding steady in February. However the PPI for cement is still riding increases from earlier last year, leaving the index 9.6% above March 2014's level. The PPI for ready-mix concrete was up 4.2% year over year.

Cost Index History Tables

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.
