National nonresidential construction spending remained virtually unchanged in December, according to Associated Builders and Contractors’ analysis of U.S. Census Bureau data released today. Nonresidential spending totaled $750.5 billion on a seasonally adjusted annualized basis in December, up 4 percent year over year.

Public sector nonresidential spending declined 0.6 percent for the month, while private sector spending increased 0.4 percent. On a year-over-year basis, public spending is up 4.8 percent while private spending is up 3.4 percent.

“History will view 2018 as a solid year for nonresidential construction spending in America,” said ABC Chief Economist Anirban Basu. “While a 4 percent increase may not sound spectacular, this figure must be considered in the context of supply constraints. Contractors have continued to suffer through growing shortages of skilled workers. While demand for construction services has been strong, the capacity of the nonresidential construction industry to put more construction in place has been suppressed by a dearth of available carpenters, glaziers, ironworkers, roofers, superintendents, electricians, etc.

“It is conceivable that the sharp increase in construction materials prices that characterized the early months of 2018 resulted in the postponement of certain projects,” said Basu. “Nonetheless, both private and public segments experienced growth in construction spending last year, with public spending up nearly 5 percent on a December-over-December basis. Moreover, the pace of growth in construction materials prices moderated sharply during the second half of last year.

“Leading indicators such as ABC’s Construction Backlog Indicator and Construction Confidence Index strongly suggest that 2019 will be another year of nonresidential construction spending growth in the United States,” said Basu. “There are many variables to watch, including interest rates, worsening skilled worker shortages, rapidly rising construction compensation costs and the U.S. economy’s broader trajectory in the context of a slowing global economy. Rapid job growth is set to create additional demand for office and commercial space. Healthier state and local government finances should help fuel additional spending growth in a number of public construction categories.”
