“Nonbuilding construction, alongside data centers, was the primary engine of growth in 2025, supporting a 5.4 percent expansion in the total dollar value of starts,” says

Sarah Martin

, associate director of forecasting at Dodge Construction Network. “In square footage terms, however, building starts declined 4.7 percent alongside weaker residential, manufacturing and institutional activity.”

Nonbuilding

Nonbuilding construction starts grew 16.3 percent in December to a seasonally adjusted annual rate of $422 billion.

Highways and bridges (up 85.2 percent month over month) and miscellaneous nonbuilding (up 35.9 percent) supported growth, while environmental public works (down 26.9 percent) and electric power/utilities (down 9 percent) faced declines.

The largest nonbuilding projects to break ground in December were the $3.5 billion Port Authority Midtown Bus Terminal (Phase 1) in New York; the $1.6 billion Entergy Legend Power Station in Port Arthur, Texas; and the $1.5 billion LAX Airport Roadway Improvements project in Los Angeles.

Commercial starts were up 9.8 percent, alongside growth in offices and data centers (up 7.4 percent month over month), parking garages (up 38.8 percent), hotels (up 74.4 percent) and warehouses (up 0.7 percent).

Meanwhile, retail starts (down 12.2 percent) posted a decline between November and December. Institutional starts declined 16.3 percent, driven by weaker education (down 18.2 percent) and miscellaneous institutional (down 26.9 percent) starts. This decline was partially offset by 7.9 percent month-over-month growth in health care facility starts.

Additionally, manufacturing pulled back 30.8 percent in December.
