Walsh Construction served as GC for a 53-acre data center campus in Hoffman Estates, IL (not Chicago proper), delivering two data centers with 38.4 MW of critical IT power. Each building includes admin space and multiple COLO data halls with 2N redundant power (UPS/PDU), evaporative AHU cooling with hot aisle containment, and pre-action fire protection. The site includes a new substation with four 40 MW transformers (160 MVA total capacity) and redundant generator power with integral belly fuel tanks. Owner and architect are listed as confidential.

QTS partnered with Mortenson Construction to build a data center in the Chicago, Illinois market. QTS is described as one of the fastest-growing data center companies in the world, with nearly 5 million square feet of usable data space across its portfolio. The partnership between QTS and Mortenson on this Chicago project represents a confirmed GC award, indicating an established relationship between the two companies in a major Midwest data center market. For sales professionals, this signals active construction activity by QTS in the Chicago area with Mortenson as the builder, presenting opportunities to engage on MEP equipment, infrastructure, and related data center supplies. Given that the project appears to be already underway or completed based on the partnership language, outreach should be prioritized promptly to capture any remaining procurement cycles or future phases.
