Rockford, Illinois (pop. 148,000) is building a 334,800-square-foot speculative industrial building on a previously undeveloped parcel in its Rockford Logistics Center, one mile from Chicago Rockford International Airport. The specifications published so far point at cargo-adjacent logistics and light distribution. Few tier-3 cities can pitch that category with a top-15 cargo airport a mile away.
What This Building Competes For
When Groundbreak covered this project in issue #5, neither Rockford nor Paducah had published building specifications. Rockford's broker listing now reports 36-foot clear height, 54-by-50-foot column spacing, 33 dock doors with room to expand, two expandable drive-in bays, and 3,000-amp electrical service. Classification: Class A distribution.
Still unpublished: floor loading, slab thickness, fire suppression type and design density, voltage, phase, process utilities, and any utility will-serve letter confirming deliverable power. The city's permit dataset shows a grading permit issued June 17 and no shell permit or plan set as of August 1. The listing also contradicts itself on timing, labeled "built 2027" while advertising September 2026 availability.
The published specs describe a distribution shell. The unpublished ones — floor loading, power density, suppression design — are what a machining, press, food-process, or chemical-process tenant needs answered before it will schedule a tour. Neither the listing, the permit record, nor the city's planning filings contains them.
RFD's cargo volume supports the logistics read. The airport handled 498,432 metric tons in calendar 2025, up 10.8% year over year, and ranks 12th nationally in FAA landed weight. UPS runs its second-largest North American hub there. Amazon Air, Maersk Air Cargo, and DSV's Atlas Air network fly regular schedules. No public demand study converts that tonnage into required off-airport warehouse square footage, and the airport authority's own FY2026 budget forecasts a 2.03% decline in cargo weight on tariff uncertainty while anticipating one cargo warehouse sitting vacant.
Categories this configuration credibly serves:
- 3PL cargo-adjacent cross-dock and distribution
- Light assembly with air-freight supply chains
- E-commerce fulfillment near a major hub
Categories it likely forecloses:
- Manufacturing needing confirmed power density above what 3,000 amps at an unstated voltage delivers
- Heavy floor loading for press or machining
- Process utilities
- Specialized suppression
Hillwood, the Dallas-based developer, carries roughly $25 million in construction cost per the development agreement. Against that sit up to $2.5 million in city reimbursement with a 20% holdback until shell completion, a separate limited-obligation TIF rebating 100% of project-generated increment through the district's 2030 levy year, and a 24-month completion deadline with default provisions. A DCEO Site Readiness grant funded the horizontal work. Hillwood holds the construction risk, so Hillwood specifies the building.
What Matching This Costs
Cushman & Wakefield's 2025 Industrial Construction Cost Guide puts building-side cost for conventional distribution shells at $57 to $110 per square foot after removing site work, varying by size. At 334,800 square feet that produces a $19 million to $37 million range. At 100,000 square feet, closer to Paducah's scale, roughly $11 million at the small-project rate. These are planning benchmarks drawn from distribution-center prototypes, not bid estimates, and they exclude manufacturing-grade upgrades.
Illinois' DCEO Site Readiness Program paid for Rockford's horizontal work, but the Capital Ready track closed April 30. Awards ran $100,000 to $5 million, reimbursement basis, 20% local match. Buildings were expressly ineligible — land acquisition, utilities, roads, grading, and remediation only. The state has awarded $115 million across 63 projects to date. No successor cycle has been announced as of August 2026. Anyone building a schedule around this program is building it around an unannounced round.
Paducah took the other route. Its $8 million GO-bond structure leaves ownership and project-management authority with the IDA for a 100,000-square-foot building approved August 11. Public ownership preserves control over the building program: Paducah can specify heavier slab, higher power density, process-capable suppression if it wants to. Whether it will is unknown. No architectural program, construction RFP, or building specification has surfaced in the public record. And the $8 million budget sits below the Cushman & Wakefield small-project benchmark, which is a scope question the design documents will eventually settle.
For any city where the council is weighing a spec-development appropriation, the financing structure determines which tenants the building can reach. That's a capital-commitment decision, not a marketing decision.
- Paducah's building specs: No architectural program, construction RFP, or broker sheet has surfaced for Paducah's 100,000-SF spec building despite the August 11 commission approval, so whether public ownership actually produces a more manufacturing-flexible design than Rockford's shell remains untestable.
- DCEO successor cycle: Illinois awarded $115 million across 63 site-readiness projects through August 5, but the Capital Ready track closed April 30 with no published Round 2 balance or successor application date.
- RFD cargo-warehouse vacancy: The airport authority's FY2026 budget anticipates one on-airport cargo warehouse sitting vacant, a tension with the 2021 environmental finding that all existing cargo buildings were occupied — and relevant context for whether 334,800 SF of off-airport space has a demonstrated absorption basis.
- Kentucky disposition data: Kentucky's KPDI program reports project status and disbursement amounts but publishes no portfolio-level table tracking completion-to-occupancy time, sale proceeds, or holding costs for publicly supported spec buildings — the missing base rate for any city underwriting GO-backed absorption risk.
