The Commerce Department said on Monday construction spending rose 1.0 percent to a nine-month high after an upwardly revised 2.5 percent surge in January.

Economists polled by Reuters had forecast construction spending falling 0.2 percent in February after a previously reported 1.3 percent jump in January.

Construction spending increased 1.1 percent on a year-on-year basis in February.

In February, spending on private construction projects rose 0.2 percent after vaulting 1.5 percent in January. Investment in private residential projects increased 0.7 percent, rising for a third straight month.

The strong gains are despite a sluggish housing market, which has been held back by higher mortgage rates, expensive building materials as well as land and labor shortages. But there are signs of green shoots emerging in the housing market as mortgage rates have declined from last year's lofty levels.

Spending on private nonresidential structures, which includes manufacturing and power plants, fell 0.5 percent in February after jumping 1.1 percent in January.

Investment in public construction projects rose 3.6 percent in February after accelerating 5.7 percent in the prior month.

Spending on federal government construction projects rose 0.9 percent to the highest level since October 2017, after soaring 5.7 percent in January.
