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.
