The Builders' Blueprint

On Friday, August 28, ConstructConnect chief economist Michael Guckes published the September 2026 Data Center Report. The headline is the one everybody will repeat: year-to-date data center construction starts total $84.1 billion, nearly three times the same period a year ago. July alone added $2.7 billion.

The number underneath it is the one that matters to a medical buildout, and it runs the other direction. Data centers now account for roughly 25% of total nonresidential building construction — down from roughly 30% a year ago. Spending tripled and share fell. That is only arithmetic if the rest of the market grew faster, which it did not — or if the money is landing on fewer, far larger projects, which is exactly what happened. July's $2.7 billion arrived across just 23 projects. The average year-to-date data center is now $1.06 billion and 701,000 square feet, against $352.8 million and 454,400 square feet in 2025. Cost per square foot is up 57% year over year to $818.20.

Read that as a capacity map instead of a market headline and it says something specific. A $1.06 billion, 701,000-square-foot project is not bid by the same electrical or mechanical contractor who prices a 4,000-square-foot dental buildout or a 30,000-square-foot medical office fit-out. It is bid by firms with the bonding capacity, the prefabrication shop, and the traveling manpower to staff a single site for two years. The capture is happening at the top of the subcontractor market. It is not, on this evidence, sweeping the mid-tier bench that actually shows up on a Houston healthcare tenant improvement.

The labor data agrees

ConstructConnect's Construction Employment Update, published Monday, August 31, puts the other half of the picture on the table. July construction employment rose 22,000 — the largest single-month gain since January. The gain was not in heavy civil or residential. Nonresidential specialty trade contractors led with 15,000 new positions, with nonresidential building adding another 4,000.

Nonresidential specialty trades are the medical buildout bench: electrical, mechanical, plumbing, drywall, flooring, millwork, low-voltage. That category added more workers in July than in any month since the winter. Pay reflects a market that is competing for them but not one that has run out — production and nonsupervisory construction workers averaged $39.24 an hour, 4.3% above the $37.62 private-sector average, and $1,550 a week across 39.5 hours against a $1,290 private-sector average.

So the two datasets released this week say the same thing from different directions. Hyperscale demand is consolidating upward into megaprojects. The trades that build clinics are adding headcount. “Everyone is booked on data centers” is a true statement about a specific tier of contractor and a misleading statement about the tier a healthcare owner is buying from. When it shows up as a line item in a Houston GC proposal — a capacity premium, a wider escalation allowance, a longer float assumption — it is now a claim with public counter-evidence attached. Ask which subcontractors, on which scopes, are actually committed elsewhere, and ask for the backlog letter.

Where the real cost pressure moved this week: customs, not crews

The pressure did not disappear. It changed address. The U.S.–Canada trade negotiation collapsed and the additional 50% duties on selected Canadian goods took effect at 12:01 a.m. Eastern on Friday, August 22, covering roughly $20 billion in goods by the U.S. accounting and about $28 billion by Canada's.

Brief #33 flagged this action when it was scheduled for August 19 and framed it as a Division 6 problem — finishes and panels, not structure. The list as implemented is worth re-reading, because AGC's identification of construction-relevant items now includes cement, paint, plywood, and fiber cable. Steel, aluminum, copper, and lumber remain under separate, pre-existing measures rather than this one. Cement matters more than it looks: Canada supplied roughly 22% of U.S. cement imports between 2020 and 2023 by USGS figures. On a medical buildout that reaches slab patching, equipment pads, imaging-room housekeeping pads, and sitework — scopes usually carried as allowances precisely because they are small.

Two dates follow it. Canada has said dollar-for-dollar counter-tariffs begin September 8, covering steel, appliances, pulp and paper, and electronics among others. And there is a transition wrinkle already biting: as the Canadian Press reported August 25, shippers are delaying loads on cash-flow grounds, though goods booked before August 22 can still avoid the levy if they are entered within 10 business days. If a supplier has material already staged, the entry date is worth a phone call this week rather than next.

One more September 3 date belongs on the same calendar for a different reason. A 100% tariff on drones over 55 pounds takeoff weight or carrying thermal imaging takes effect September 3, under an order signed August 13. Per an ABC member survey reported by Construction Dive on August 26, 36% of ABC members fly drones on jobsites and 97% of those use DJI hardware, with 81% using them for site progress monitoring and 50% for inspections. Most jobsite units fall under the weight threshold, but thermal payloads — the ones used for roof moisture surveys and envelope commissioning on a new clinic — do not. If progress documentation or envelope verification is a contract deliverable on your project, confirm the vendor owns the equipment already.

Two Houston-relevant signals

Healthcare capital is still committing. On August 24, Parkview Health broke ground on a $200 million, roughly 200,000-square-foot hospital and medical office campus in West Lafayette, Indiana — up to 40 inpatient beds, a 24-hour emergency department, surgical suites, and imaging, targeting June 2028 completion and about 250 jobs. It is not a Houston project, but it is a useful marker: systems are still underwriting new campuses into a 2028 delivery window, which is the same window a Houston owner starting design this fall is buying into.

Closer to home, Realty News Report reported on August 25 that Interra Capital Group is under contract to acquire the two-tower Park Towers complex on Loop 610 near Memorial Park for approximately $110 million — 552,250 square feet at roughly $200 per square foot, 89.5% occupied, with Regent Properties selling. Existing Houston office is trading at a basis that makes conversion and repositioning arithmetic materially different from ground-up. For a practice group weighing a new build against taking space in a repositioned tower, that basis is the number the landlord's TI allowance is eventually negotiated against.

Action Items

1. Make the capacity premium name names. If a proposal carries a data-center capacity allowance, an extended-float assumption, or a widened escalation contingency, ask which trades and which specific subcontractors are committed elsewhere, and ask for a current backlog letter from each. Nonresidential specialty trades added 15,000 workers in July. A premium priced against a sector headline instead of against your actual bid list is a negotiating position, not a cost.
2. Bid the mid-tier MEP bench directly and independently. The consolidation is at the top of the market — $1.06 billion average projects absorb the firms that can staff them. Solicit at least three mid-tier electrical and mechanical bids on your own, outside the GC's standing list, and compare them against the GC's carried numbers. On a healthcare fit-out, MEP is where both the money and the schedule live.
3. Convert the small cement, paint, and panel allowances into quantified line items before September 8. Slab patching, equipment and imaging housekeeping pads, sitework, coatings, and panel products are exactly the scopes carried as lump allowances and exactly the ones the August 22 list reaches. Get quantities and unit prices now, and confirm with suppliers whether staged material was booked before August 22 and can still be entered inside the 10-business-day window.
4. Write the escalation clause to name the measure, not the mood. Specify which packages escalation applies to, which published index governs, and what the base month is. “Market conditions” language written this week will be read against a September 8 counter-tariff round and a labor market that added jobs — and ambiguity in that clause resolves toward whoever drafted it.
5. Confirm who owns the documentation equipment. If drone progress capture, thermal roof scanning, or envelope commissioning is a contract deliverable, verify the vendor holds the hardware today rather than procuring after September 3. A 100% tariff on thermal-payload units turns a routine deliverable into a change order or a quiet substitution to a lesser method.

The Takeaway

The most expensive assumption in a Houston medical, dental, or veterinary buildout right now is a true fact applied to the wrong tier. Data center construction really did nearly triple. It also got narrower — fewer projects, three times the average size, 57% more per square foot — and its share of the nonresidential building market actually shrank. Meanwhile the specialty trades that frame, wire, pipe, and finish a clinic posted their strongest hiring month since January. Both things are true at once, and only one of them is on the cover of the report. Disciplined project operations is mostly the habit of asking which number applies to this job: which subcontractor, which scope, which entry date, which index, which month. The owners who hold budget and schedule through the fall will not be the ones who predicted the market. They will be the ones who made every premium in the proposal say what it was for.

Forward Always.
