Data Centers Carry the Number, Not the Clinic: Why Nonresidential Spending Up 0.6% Hides a Slipping Healthcare Line and a Fed Leaning Toward Another Hike

Two releases this week frame the market a clinic owner is actually buying in. On November 2, the Census Bureau reported September construction spending down 1.9% to a seasonally adjusted annual rate of $2.186 trillion, while nonresidential spending rose 0.6%, its sixth straight monthly gain. On October 28, the Federal Reserve held its rate at 3.75% to 4% by a 10-2 vote, with both dissenters preferring another hike. The nonresidential gain is a data-center story; for a Houston medical, dental, or veterinary owner, the useful reading is what sits underneath it.

What the Census release says

Associated Builders and Contractors (ABC) chief economist Anirban Basu analyzed the September data, and ENR and other trade outlets reported it the same day. The detail:

• Total construction spending: down 1.9% from August to $2.186 trillion, and down 2.7% from September 2025. The first nine months of 2026 are 2.9% below the same period of 2025.
• Residential: down 5.4% on the month and 8.8% on the year, which is what pulled the total down.
• Nonresidential: up 0.6% to $1.325 trillion and up 1.8% on the year. Private nonresidential rose 1.1% to $790.6 billion; public fell 0.1%. Eight of the 16 nonresidential subcategories rose.
• Data centers: up 8.6% on the month, a 217% annualized rate since May. Basu said excluding data centers and the closely related power category, nonresidential spending fell in September.
• The lines a clinic owner watches: healthcare -0.3%, commercial -0.2%, education -0.1%. Manufacturing edged up 0.1% but is down about 17% from a year earlier.

Basu expects momentum to stay concentrated in AI-related segments for several months, citing rising Treasury yields and continuing materials price increases, and said larger contractors are better positioned for data center and power work.

Where the sources disagree on healthcare

One caution before quoting any healthcare year-over-year number. ConstructConnect chief economist Michael Guckes, as reported by ENR, said spending on military, healthcare, and warehouse construction was each up 30% or more from a year earlier, and called the breadth of gains encouraging. The Census Bureau's own August table, the most recent we could read directly, showed healthcare construction at $75.8 billion, 3.0% below August 2025. Those two statements do not obviously agree, and we could not open the September Census table to reconcile them. We report the month-over-month change that two sources support (-0.3%), flag the year-over-year disagreement, and recommend any owner or lender quoting a healthcare growth rate pull it from the Census Construction Put in Place table directly.

The Fed leg of the story

On October 28 the Federal Open Market Committee held its target range at 3.75% to 4%, after raising it by a quarter point in September. The vote was 10-2; Cleveland Fed President Beth Hammack and Governor Lisa Cook dissented in favor of another 25-basis-point hike. The statement described economic activity as expanding at a strong pace and inflation as still elevated. The committee next meets December 8-9, and CME FedWatch showed an 82.6% probability of a quarter-point hike at that meeting at the time of reporting.

Market probabilities move daily and are not a forecast. For an owner financing a buildout, the point is narrower: the direction of the next move that the committee itself signaled, through two dissenters, is up, and construction loans and permanent financing are priced off that path.

Reading the two together

Our reading, which is analysis and not a statement by the Census Bureau, ABC, or the Fed: spending is work in place, a lagging measure of projects already underway, and this month it is being carried by a lane that is not competing for the same dollars as a medical office. The risk to a clinic owner is not that demand disappeared. It is that headline numbers look healthier than the market the owner is buying in, and that the same electrical, mechanical, and copper-heavy scopes a data center consumes are the ones a surgery center or imaging suite needs. Brief #42 reported steel order books full through spring 2027 and inputs to new nonresidential construction up 11.9% in a year; nothing in this week's data eases that.

The Houston angle is interpretation, not a new local dataset. We found no Houston-specific release this week that we could verify against a primary or trade source, so this brief does not claim one. The local picture from earlier briefs stands: Houston added 14,100 construction jobs in the year to August (Brief #40), and labor is the scarce input.

By the Numbers

• $2.186 trillion — total construction spending, September, seasonally adjusted annual rate; -1.9% on the month, -2.7% on the year (Census)
• +0.6% / +1.8% — nonresidential spending, month over month / year over year; sixth straight monthly gain (Census, via ABC and ENR)
• +8.6% — data center spending, September; 217% annualized since May (ABC)
• -0.3% / -0.2% / -0.1% — healthcare / commercial / education spending, month over month (ABC)
• -17% — manufacturing construction spending versus September 2025 (ABC)
• 3.75%–4% — federal funds target range after the October 28 hold; vote 10-2, both dissents for a hike (Fed)
• 82.6% — CME FedWatch probability of a quarter-point hike at the December 8-9 meeting, as reported October 28

Six moves for a Houston medical, dental, or veterinary owner

1. Underwrite on your own scope, not the headline. A nonresidential number that excludes data centers and power is down. Build the budget from dated quotes for your trades, not from national averages.
2. Put financing on the calendar before December 8. Ask your lender for rate-lock and extension terms now, and decide what a quarter-point move does to your carry. A decision made before the meeting costs less than one made after it.
3. Commit electrical gear and copper-heavy scopes first. Switchgear, generators, panels, and medical gas and plumbing compete in the same supply chains as data center work. Get written lead times and delivery dates, and treat a quote without an expiry as incomplete.
4. Write escalation terms into the contract. With input prices rising faster than bid prices (Brief #42), require stated assumptions, a hold period, and a defined adjustment mechanism, so risk is priced once and visible rather than discovered in change orders.
5. Ask a mid-size builder for named people. Basu expects larger contractors to be best positioned for data center and power work. A builder with room on its schedule should be able to name the project executive, superintendent, and lead foremen.
6. Finish design before release. Resolved drawings are the cheapest hedge against rates, materials, and labor at once. An 11,000-square-foot clinic and a 4,000-square-foot dental suite both benefit.

The Takeaway

The national number is up and the clinic's line is flat to down. A thin nonresidential gain driven by one lane, a Fed leaning toward another hike, and materials costs that have not eased describe a market where the owner who fixes financing, long-lead gear, and named crews early controls more of the outcome than the one who waits for the headline to improve.

The disciplined response is operational: price from your own scope, calendar the financing decision, commit long-lead packages with written dates, put escalation terms in the contract, and secure named people. Spending data and rate probabilities are inputs to planning, not forecasts.

Forward Always.
