Construction spending is still on the rise in building sectors that use large amounts of glass, according to the U.S. Census Bureau’s latest report on value of construction put in place.

School construction was strong in October.

The educational category led the way in October construction spending with a 9-percent increase from September and a 12-percent jump from October 2016, eclipsing the $100 billion mark on a seasonally adjusted annual rate.

Another key component on the institutional side was healthcare construction, which saw monthly and yearly increases of 2.8 and 9.3 percent, respectively. The transportation category, which has recently been boosted by terminal construction that often includes large spans of glass, ticked up 3.8 percent from the previous month and 13.5 percent from the previous year.

The ever-important office segment also increased on a monthly basis, rising 5.3 percent, with its total coming in just under $70 billion. That category, however, has seen a 3.4-percent decline year-over-year.

Lodging construction has also continue to show strength, with a 2.1-percent increase on a monthly basis and 12.3-percent bump from the same time last year. The other commercial subsector, which includes retail construction, declined 1.6 percent for the month but is still up 6.8 percent year over year.

Despite these gains, non-glassy sectors such as power, sewage, highway and water supply, along with manufacturing building, have held the overall nonresidential numbers back. Nonresidential construction on the whole saw a 2.1-percent increase in October but was unchanged from a year ago.

As has been the case in recent months, multifamily construction continues to settle back, with monthly and yearly declines of 1.6 and 2 percent, respectively. Single-family is leading the residential side, increasing 0.3 percent from September and 8.9 percent from October 2016.

“One could scarcely imagine circumstances more consistent with rapid growth in nonresidential construction spending,” Associated Builders and Contractors chief economist Anirban Basu said in his analysis. “The U.S. economy is humming, coming up on two consecutive quarters of 3 percent growth on an annualized basis. Consumers, who have been the driving force of the recovery to date, are more confident than they have been in 17 years.”

He added that stock prices have surged, interest rates remain low, corporate tax reform is likely on the way and the worldwide economy is strong, which all point to accelerated growth.
