ABC’s Construction Backlog Indicator is the only economic indicator that reflects the amount of work that will be performed by commercial and industrial construction contractors in the months ahead. The Construction Confidence Index is a diffusion index that signals construction contractors’ expectations for sales, profit margins and staffing levels. View the methodology for both indicators. 


Construction materials prices expanded just 0.1 percent in December and are up 1.3 percent year over year, according to a Jan. 15 Producer Price Index released by the Department of Labor. Nonresidential construction materials prices also rose only 0.1 percent for the month and are 1 percent higher than the same time one year ago. 

“Materials prices continue to be unusually well behaved, neither rising nor falling aggressively on a month-to-month basis,” said Associated Builders and Contractors Chief Economist Anirban Basu. “That said, there was some volatility in individual input segments, including natural gas prices, which were up 7.8 percent, and crude petroleum, which was up 7.1 percent,” Basu said. “These increases are at least partially explained by seasonal factors and do not likely foreshadow aggressive price increases going forward. At the same time, certain input prices fell, including softwood lumber, down 3.3 percent, and nonferrous wire/cable, down 1.4 percent.”

Overall, the nation’s wholesale goods prices expanded 0.4 percent in December and are up 1.2 percent year over year. 

“While there is never a guarantee of input price stability, for now things seems reasonably calm,” Baus said. “The world economy is anticipated to accelerate this year to 3.6 percent growth, up from closer to 3 percent last year. That will help push the level of demand for construction materials higher, but not necessarily in ways that are especially damaging to a still-benign U.S. nonresidential construction industry outlook.”

  • Fabricated structural metal product prices are up 0.1 percent and have risen 0.6 percent on a year-over-year basis.
