Three data center campuses are approved in one Yorkville corridor: Prologis “Project Steel” (9M+ sq ft, March 24 2026), Pioneer “Project Cardinal” (17M sq ft, November 2025), and CyrusOne Phase 1 (2.1M sq ft, breaking ground Q1 2026). On April 14 2026 Mayor Purcell publicly declared “no more appetite” for additional data center projects. These three are the entire Yorkville pipeline, and mechanical and fire subs are bidding them now. Three parallel RFQs are moving through subcontractor selection for chilled-water piping, butterfly and control valves, grooved fittings, CRAH and AHU packages, and pre-action fire suppression. For a Chicagoland industrial distribution rep, this is the densest capex corridor in your territory this quarter.
Data center construction moves faster than pharma. Permit-pull to first mechanical RFQ can close inside a single quarter.
- CyrusOne Phase 1 is breaking ground Q1 2026. Russ Whitaker (CyrusOne zoning counsel) testified February 10 that construction begins Q1 with power delivery later this year. Mechanical sub selection closes in 30-60 days. Miss this week and the qualified-vendor list locks without you.
- Project Steel cleared March 24 2026 (5 weeks ago). Prologis has not publicly named its GC; the RFP is live or imminent. A call now to Prologis industrial-construction procurement, or to Yorkville Community Development for that contact, lands before vendor lists lock.
- Project Cardinal was approved November 2025. Pioneer's GC may already be picked; the window is now subcontractor-package tier through Pioneer's mechanical contractor.
Three timelines, one corridor. Work all three in the same trip.
City side (public filings)
- Krysti Barksdale-Noble · Community Development Director · knoble@yorkville.il.us · 630-553-8573. Oversees all three case files. Best single intake to identify developer PMs.
- David Hansen, Sara Mendez, Thian Dim · planning staff on these files. Use for site-plan or permit-status pulls.
- Bart Olson · City Administrator. Context only.
Developer principals + counsel
- Matt McCarron · Director, Pioneer Development LLC (Project Cardinal). 30 N Gould St #38989, Sheridan WY · 847-738-5005 (Chicagoland area code on the WY filing, likely operational line).
- Katie Fraser, PE · Director, Development Services, Prologis. Project Steel city-facing project lead, presented at Yorkville EDC public hearing.
- John Hatem · President, CyrusOne. Owns Global Procurement + U.S. Design and Construction. Right title at corporate level for Yorkville construction questions.
- Russ Whitaker· Rosanova & Whitaker Ltd., CyrusOne zoning counsel. Firm: 445 Jackson Ave Ste 200, Naperville · 630-355-4600.
- David Silverman· Mahoney, Silverman & Cross LLC, Project Cardinal project attorney for Pioneer. Faster route to Pioneer than the WY entity address.
Political context
- Mayor John Purcell · supportive of the three; closed to future proposals.
- Alderman Rusty Corneils · single dissenting vote on Project Steel.
Likely mechanical bid list
MEP subs most likely to win Chicagoland packages at this scale are Mechanical Contractors Association of Chicago members: Hill Mechanical, F.E. Moran, MESCO, Murphy & Miller. Calling their procurement desks directly is faster than the developer route. CyrusOne IL is on a Project Labor Agreement with IBEW (per IBEW Sixth District VP Michael Clemmons + IL AFL-CIO President Tim Drea at the Aurora groundbreaking). PLA filters the realistic CyrusOne mechanical bid list to MCA-Chicago union shops above. Saying “PLA bid list” on the call lands as informed.

- Piping: carbon steel condenser water; copper or press-fit steel chilled water; CPVC on CRAH drains; black iron pre-action fire main. Grooved-end speeds install. Second-source inventory matters.
- Valves: butterfly on chilled/condenser; check on pumps; 2-way and 3-way control on CRAH/AHU bypass; ball for isolation. High cycle count. Service life beats lowest-cost.
- Fittings: grooved couplings, flange adapters, mechanical tees throughout.
- HVAC: CRAH plus AHU; spiral and rectangular ductwork. Cooling towers required. Yorkville has no chilled-water district.
- Fire: pre-action in IT suites, wet pipe in offices/MEP rooms, FM-200 or Novec in key equipment rooms. Bladder tanks, detector loops, compressor packages.
If your book leads in any of these, this corridor is the largest Chicagoland opportunity of the quarter.
Opener 1 · Chicago MCA mechanical sub procurement desk (fastest route)
“Hi, this is [Name] with [Distributor]. I carry grooved piping, butterfly and control valves, and CRAH-package air distribution in Chicagoland. The Yorkville data center corridor was fully approved in March, three campuses. I want to get on procurement for your Yorkville packages before the vendor list locks. If you have a bid coming up on Project Steel, Project Cardinal, or CyrusOne Yorkville, who's the right person to send my book?”
Opener 2 · Krysti Barksdale-Noble's office (city-side route to developer PM)
“Hi Krysti, this is [Name] with [Distributor]. Chicagoland piping and valves supplier. Trying to reach the project management lead for Prologis on Project Steel. Can you point me to Prologis industrial construction procurement, or share the case file's current GC of record? Want to make sure our product is in front of the right bid list before permits progress.”

- Named GC or CM-at-Risk for Project Steel, Project Cardinal, or CyrusOne Yorkville: not yet on the public record. Resolution: Kendall County permit portal, Construction Dive, ENR Midwest.
- Prologis Project Steel construction PM (PARTIAL): Katie Fraser PE confirmed as city-facing lead. Construction-PM seat opens when active Workday req R6340 (Director, Customer-Led Development, Central Region, Chicago) fills. Watch that hire.
- Pioneer MEP procurement (PARTIAL): Matt McCarron + David Silverman are the two routes-in. Burns & McDonnell named as Pioneer's sound-study consultant on PZC 2025-08, likely engineer-of-record candidate beyond acoustic-only. Pioneer LLC almost certainly has no separate MEP-procurement seat; that scope runs through B&M or the eventual GC.
- CyrusOne Yorkville site PM (PARTIAL): John Hatem owns U.S. Design + Construction at corporate. Yorkville-specific site PM not on public record (KKR-private post-acquisition). The PLA + IBEW finding above is the actionable replacement intel.
- Project Steel mechanical bid list: case still PUD-stage (approved 2026-03-24); construction-permit filings expected 2026 Q3. Resolution: direct outreach to MCA Chicago members above + Yorkville DocumentCenter monitor.
- Call Hill Mechanical, F.E. Moran, MESCO, and Murphy & Miller procurement with Opener 1. Four calls, four vendor-list shots before Project Steel locks.
- Call Krysti Barksdale-Noble with Opener 2 as the city-side route to Prologis.
- Pull Project Steel (case 2025-07) and Project Cardinal (PZC 2025-08) files from Yorkville's portal. Scan the plan-commission packet for sub-consultant or preliminary bid-list references.
- Drive the corridor: Eldamain Road, Galena Road, Route 47. First-site-observation is credibility when you call subs.
