Cartis diligence evidence schedule

US Signal IA01 Des Moines Data Center

PRJ-1247 · Site · Waukee, Iowa, United States

Record last updated Oct 28, 2026

Scope and capacity

US Signal reported on May 14, 2026 that walls were rising for the Des Moines expansion following its November groundbreaking. This confirms expansion construction progress while the existing IA01 facility continues operating; it does not establish completion of the new capacity. US Signal IA01 Des Moines Data Center is an operating US Signal data-center facility in Waukee, Iowa. US Signal's IA01 facility at 390 N Alices Road; current infrastructure is separated from expansion work. The retrofit records utility feed capacity: 5000 kVA; backup generation capacity: 3000 kW; ups capacity: 2000 kW; cooling capacity: 550 tons. Utility service, UPS, standby generation, cooling, facility power and IT load are kept in their source-defined scopes rather than collapsed into one capacity number. Where reliable public evidence for ownership, project financing, permitting, tenants or water arrangements was not established, Cartis records the research gap explicitly instead of inferring a fact.

Headline: 0.2 MW Planned critical IT
