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.

ENR's lumber prices post modest rebound in December.

Construction Economics, Materials Trends, Lumber, DrywallENR's lumber prices post modest December rebound

Lumber prices posted a modest rebound in December, after declining an average of 0.4% in November, according to ENR's 20-city average price for three species of 2x4s. This month, prices for that group of lumber products averaged a 0.5% increase. On a year-to-year basis, ENR's price for the most commonly used species of 2x4s is up 5.6% for the year. The Bureau of Labor Statistics' producer price index for lumber in October was 5.3% above 2013's level. Those gains may be short-lived. Mill prices tracked by Crows reports are down 11.2% from December 2013 (see table).

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.
