Aug 6, 2026 - Data Centers Continue to Dominate Commercial Building Spending

• US construction and engineering spending on nonresidential buildings is expected to fall 5% in 2026 after remaining flat in 2025, according to FMI’s third-quarter 2026 North American Engineering and Construction Outlook. Data centers will remain the strongest major growth area, with spending projected to rise 21% amid high demand for AI infrastructure and extremely low available capacity in leading markets. Religious construction is forecast to increase 13%, although growth is concentrated in a small number of large campus projects. Communication spending is expected to rise by 3% as AI-driven network demand and broadband construction activity support growth. Challenges will be most severe in manufacturing, where spending is forecast to fall 17% as semiconductor and battery projects move beyond peak construction phases. Warehouse spending is projected to drop 10% because of fewer recent starts, while lodging spending is expected to decline 9% as development focuses on conversions and luxury projects.
• The US hotel construction pipeline totaled 5,975 projects and 703,001 rooms in the second quarter of 2026, down about 4.9% and 4.6%, respectively, from a year earlier, according to the Q2 2026 US Construction Pipeline Trend Report by Lodging Econometrics. Despite the overall decline, new project announcements in Q2 2026 rose 18%, and construction starts increased 14%. Upper midscale and upscale hotels accounted for 59% of projects, while luxury and upper upscale pipelines reached record levels. Hotel conversions also increased 15% to a record 1,567 projects. Lodging Econometrics expects 661 hotels to open in 2026, up 1.3% from 2025, with openings accelerating to 738 in 2027 and 832 in 2028.
• The total value of nonresidential building starts fell 9.1% in June compared to May, according to Dodge Construction Network. Commercial starts rose 1.2%, led by parking garages (up 29.5% over May), warehouses (+15%), hotels (+8.1%, and retail stores (+3.2%). Spending on offices and data centers fell 3.7% month over month in June. Institutional starts rose 2.5% in June as an 8% rise in educational projects and a 32.9% increase in "other" institutional building starts helped offset a 29.9% drop in healthcare starts. Construction starts related to manufacturing fell 62.9% in June from May.
• Construction industry confidence held steady in the second quarter, with Engineering News-Record's (ENR) Construction Industry Confidence Index remaining at 54 and its Economic Index staying at 48 for a third consecutive quarter. Index readings of 50 or more suggest a healthy industry. Executives reported weaker views of the current market but slightly improved expectations for the next 12 to 18 months. General contractors and construction managers were the most confident, while design firms improved and subcontractors slipped. Larger firms remained more optimistic than smaller ones. More than 75% of ENR respondents reported upward price pressure. Industry watchers suggest inflation, higher rate expectations, and materials costs are weighing on contractors, though strong demand, especially for data centers, continues to support the market.
