A moderation in data center work caused June’s Dodge Momentum Index (DMI), issued by Dodge Construction Network (DCN), to fall 1.9% in June to 271.7 from an upwardly revised May reading of 277.1. Over the month, commercial planning dropped 6.8% while institutional planning momentum grew 10.9%.

The DMI is a monthly measure based on the three-month moving value of nonresidential building projects going into planning. It is shown to lead construction spending for nonresidential buildings by a full year to 18 months.

“Despite June’s pullback, nonresidential planning remains on solid ground,” says Sarah Martin, DCN’s director of economic research. “Data center activity continued to drive DMI, but its pace moderated from the extraordinary levels seen in recent months, driving the DMI to pull back over the month. Otherwise, planning activity accelerated across nearly every other sector.”

While the pullback in data centers drove June’s decline, planning activity for traditional office buildings, warehouses, retail stores, healthcare, government and hotels improved. Year-over-year, the DMI was up 21.8% when compared to June 2025. The commercial and institutional segments were up 21.8% over the same period. When removing data centers, the commercial segment would be up 7.6% from year-ago levels.

Fifty-nine projects valued at $100 million or more entered planning throughout June. The largest commercial projects included the $500 million Stak Energy AI Data Center Campus in Prudhoe Bay, Alaska, the $480 million Project Swan Data Center Complex in Lakeland, Florida, and the $456.8 million Parcel A Data Center in Manassas, Virginia. The largest institutional planning projects included the $437 million DCSO Correctional Facility in Nashville, the $320 million Cone Health Hospital in Winston-Salem, North Carolina, and the $303 million El Camino Health Hospital in Los Gatos, California.
