After three straight months of slowing momentum, nonresidential planning activity bounced back in April 2026, with the Dodge Momentum Index climbing 6.2%. While data centers continue to dominate the pipeline, signs of stabilization in offices, hotels and healthcare offer a cautious tailwind for the glazing and building envelope sector.
Planning Pipeline Finds Its Footing
After a rough first quarter, the Dodge Momentum Index (DMI) delivered the most encouraging signal nonresidential construction has seen all year. According to Dodge Construction Network, the DMI rose 6.2% in April 2026 to 264.2, up from the downwardly revised March reading of 248.8. Over the month, commercial planning grew 8.1% and institutional planning momentum improved 1.5%.
That matters because the DMI is a leading indicator. It is a monthly measure based on the three-month moving value of nonresidential building projects going into planning, shown to lead construction spending for nonresidential buildings by a full year to 18 months. In other words, what entered planning in April is the work that glazing contractors, curtain wall fabricators, and building envelope consultants will be bidding through 2027 and early 2028.
Data Centers Still Dominate — But No Longer Alone
The story all spring has been data centers carrying the index on their backs. In March, that dependence was nearly absolute. "Planning momentum in March was powered almost entirely by data center projects, with most other sectors easing back," said Sarah Martin, Associate Director of Forecasting at Dodge Construction Network. "For some categories, this reflects a natural reset after the outsized growth in late 2025. But for others, elevated macroeconomic risks are likely beginning to feed into planning decisions."
April told a slightly different story. "After three months of slowing momentum, nonresidential planning began to find its footing in April," said Martin, now identified as Director of Economic Research at DCN. "Data centers remain the largest driver behind growth in the Dodge Momentum Index, but several other sectors appeared to stabilize over the month. Macroeconomic risks remain weighted to the downside, with labor shortages, higher material costs and supply chain disruptions weighing on owner confidence in the near-term."
What grew, and what slowed:
- Planning activity for traditional office buildings, data centers, warehouses, hotels and parking garages grew in April, while retail store planning slowed pace.
- On the institutional side, education and healthcare planning re-accelerated, while recreational, public and religious planning slowed down over the month.
Year-over-year comparisons help frame the underlying trend. The DMI was up 14.1% compared to April 2025. The commercial segment was up 37.2% (+5.8% when data centers are removed) and the institutional segment was up 28.8% over the same period. Strip out the hyperscale data center boom, and the rest of nonresidential is essentially flat to modestly positive — a more honest read on where envelope demand is heading.
What's Actually Entering the Pipeline
The headline projects show where capital is concentrating. A total of 44 projects valued at $100 million or more entered planning throughout March. The largest of those projects included the $500 million Google Data Center (Building One) in Buffalo, West Virginia, the $470 million Stargate Data Center (Freebird Phase 2) in Burlington, Texas and the $450 million Jay Data Center in Jay, Maine. The largest institutional projects were the $256 million Navy Seal Museum in San Diego, California, the $178 million Lurie Children's Hospital in Downer's Grove, Illinois, and the $175 million Unaccompanied Housing improvement project at Naval Base Coronado in California.
For envelope specifiers, that mix is telling. Hyperscale data centers typically demand limited high-performance glazing but enormous volumes of insulated metal panels, louvers, and structural framing. The healthcare and military housing projects, by contrast, drive demand for thermally broken aluminum systems, blast-resistant glazing, and bird-friendly façade detailing now standard in federal specifications.
Practical Implications for the Building Envelope Industry
For architects and specifiers: April's stabilization beyond data centers — particularly the return of office and hotel planning — suggests the long-anticipated 2027 recovery in commercial glazing demand may finally have a foundation. Specifications written now will land on jobsites just as that wave breaks.
For general contractors and glazing subs: With data centers, warehouses, hotels and parking garages growing in April, preconstruction teams should be sharpening estimates on unitized curtain wall, storefront-heavy hospitality envelopes, and the structural glazing packages typical of mixed-use parking podiums.
For manufacturers and distributors: The DMI's 12-to-18 month lead time means April 2026 planning translates to material releases roughly mid-2027 through late 2028. Capacity planning, tariff hedging, and inventory positioning should be calibrated to that window, not to current trailing-twelve-month order books.
For building envelope consultants: The renewed activity in education and healthcare planning brings stringent performance and resilience requirements back into play. Expect more requests for thermal modeling, condensation analysis, and life-cycle carbon documentation as those projects mature toward design development.
The Caveat
Martin's reference to "labor shortages, higher material costs and supply chain disruptions" is not boilerplate. Tariff volatility on aluminum extrusions and float glass continues to inject uncertainty into bidding, and one month of improvement does not end the broader pullback that KMR and other industry forecasters have flagged for 2026 architectural glass volumes. April's bounce is welcome, but the smart read is cautious optimism — not a green light.
