Two Markets, One Bid Room: June's Spending Split Hands Houston Medical Buildouts a Leverage Window That Closes August 19

The June construction spending report landed Monday, August 3, and it confirms what your bid room has been feeling all summer: there are now two commercial construction markets in this country, and your project is in the one that's shrinking. Total spending came in at a $2,166.5 billion seasonally adjusted annual rate—down 3.2% from June 2025. Data-center construction rose another 7% for the month and is up 46% year over year. Strip data centers out, and private nonresidential spending fell 0.6% in June and sits 7.9% below last year. Healthcare construction—the category your medical, dental, or veterinary buildout lives in—is down 4.6% year over year. Spending declined in eight of the sixteen categories ABC tracks, and AGC's analysts said plainly that weakness is spreading across much of the market.

Here is what that split means at the negotiating table. ABC's backlog data shows the 13% of contractors holding data-center work carry 11.0 months of backlog. The other 87%—the GCs who actually bid your clinic, operatory, or surgical suite—are sitting at 8.5 months and thinning. Add AGC's warning that highway funding, the largest public category, faces a sharp drop if Congress doesn't renew the surface transportation law before it expires at the end of September, and the picture sharpens: more capable GCs and subs are about to chase fewer private jobs. For a Houston medical, dental, or veterinary owner with a funded project, this is the most competitive bid environment in two years—deeper bid lists, sharper fees, more negotiating room on general conditions. But the window has a hard date on it. The 50% Section 338 tariff on Canadian imports—announced July 20 and effective August 19—covers cement, paint, plywood, and fiber cable, and it applies regardless of USMCA origin. Canada supplies roughly 20% of U.S. cement imports. Concrete, drywall finishes, paint packages, and low-voltage cabling bid after mid-August will carry that load; bids locked before it won't. Leverage on one side, a tariff clock on the other. Here is how disciplined owners are converting the window:

• 1. Take funded projects to market now, not in Q4. An 8.5-month average backlog among non-data-center GCs means hungrier pricing this month than you will see after the Aug. 19 tariff and a possible September public-funding cliff push more cost and more bidders into the same pool.
• 2. Lock concrete, paint, and finish pricing before August 19. Get written supplier quotes with validity dates on every cement-, plywood-, and paint-heavy package this week. CBP has not yet issued implementing instructions, so scope could still shift—but a locked price beats a contested classification.
• 3. Keep the tariff clause—and extend it to Section 338. The change-in-law and tariff-contingency language from Briefs #28 and #30 should now expressly cover Section 338 duties. Metals stay under Section 232 (50% raw / 25% derivative)—excluded from the new action, so book zero movement there.
• 4. Don't over-read your leverage on electrical scope. Data centers are still absorbing electricians, switchgear, and transformers—especially in Texas, where ERCOT keeps approving new AI load. Hold long-lead electrical procurement discipline even while you press for savings everywhere else.
• 5. Ask your GC what jobsite data you'll actually receive. Procore's July 29 agreement to buy DroneDeploy for $845 million signals where documentation is heading: reality capture and AI progress verification folded into the mainstream PM platform. Owners should start specifying capture cadence and data ownership in their contracts now, while it's a differentiator rather than a line item.

By the Numbers:

• Total June construction spending: $2,166.5B SAAR · −0.1% m/m · −3.2% y/y (Census, released Aug. 3)
• Private nonresidential ex-data centers: −0.6% m/m · −7.9% y/y · healthcare category: −4.6% y/y (ABC)
• Data-center construction: +7% m/m · +46% y/y · declines in 8 of 16 ABC categories
• Backlog: 11.0 months for the 13% of contractors with data-center work · 8.5 months for the other 87%
• Section 338 Canada tariff: 50% on cement, paint, plywood, fiber cable · effective Aug. 19 · Canada ≈ 20% of U.S. cement imports
• Procore → DroneDeploy: $845M cash · announced July 29 · expected close by end of 2026

Weekly Action Items:

1. Move any funded medical, dental, or veterinary project into the bid market this month—document current GC backlog positions in your bid tabs so the leverage shows up in fee and general-conditions negotiations, not just base price.
2. Issue RFQs this week on every concrete, paint, millwork, and low-voltage package with pricing validity through contract award, and add Section 338 to your tariff-contingency clause before anything is signed.
3. Add a jobsite-data requirement to your next GC agreement: capture cadence, deliverable format, and owner data rights—the Procore/DroneDeploy consolidation means this is about to become standard, and owners who specify it early get it priced at zero.

Forward Always.
