Nonresidential construction spending increases for the 16th straight month, in September 2023

National nonresidential construction spending increased 0.3% in September, according to an Associated Builders and Contractors analysis of data published today by the U.S. Census Bureau. On a seasonally adjusted annualized basis, nonresidential spending totaled $1.1 trillion.

Spending was down on a monthly basis in 9 of the 16 nonresidential subcategories. Private nonresidential spending increased 0.1%, while public nonresidential construction spending was up 0.5% in September.

“Nonresidential construction spending increased for the 16th straight month in September,” said ABC Chief Economist Anirban Basu. “While some private categories, including power, commercial and amusement and recreation saw healthy month-over-month increases, publicly financed construction accounted for more than 72% of September’s rise. Given increased federal infrastructure spending and exorbitant financing costs for private construction, that dynamic should remain firmly in place over the coming months.”

“Despite a small decrease in spending in September, manufacturing construction remains the nonresidential sector’s outperformer,” said Basu. “Spending in the category is up 62% over the past year and accounts for nearly 43% of the year-over-year increase in nonresidential construction put in place. With several industrial megaprojects ongoing, spending in the manufacturing segment will remain elevated for several quarters.”

Components of the $9-million structural concrete construction phase included a 700-foot-long, below-grade baggage-handling tunnel; metal decks covered in poured-in-place concrete; slab-on-grade for the new terminal; and 10 exterior architectural columns––each 56-feet tall and erected at a 14-degree angle.
