Data Centers & Mission Critical

The two-story facility spans approximately 210,000 SF and is designed to deliver 36 megawatts (MW) of critical load capacity, supporting high-density artificial intelligence (AI) workloads and digital data processing. In response to Arizona’s arid climate and water scarcity concerns, the data center will utilize ThermalWorks’ advanced waterless cooling system. $78.69M Project Size: 210,000 SF Schedule: 06/2024 – 06/2025 (Estimated, currently on schedule) Complexity: Highly Complex; 36 MW of critical load capacity with an innovative waterless cooling system that addresses Arizona’s water scarcity, saving over 94 million gallons annually.

Haydon partnered with NRS Logistics to deliver their first U.S. facility in support of Arizona’s semiconductor industry: a three-building campus featuring an H-4 classified chemical storage warehouse, office space, a tank service depot with a bridge crane, covered gas storage, and a yard for up to 540 isotainers. The project included complex MEP systems, blastproof fixtures, spill containment, and a DOAS HVAC system. Haydon led preconstruction efforts, guiding cost-effective design and infrastructure planning while coordinating closely with the City of Casa Grande and its Fire Department to manage deferred plan reviews, inspections, and emergency response system approvals. This effort required precise system integration, phased execution, and collaboration with AHJs to deliver a technically complex, safety-critical facility on schedule.

The MOS21 wafer fabrication plant was Haydon’s first large-scale advanced technology project—and the one that sparked our long-standing passion for building mission-critical facilities, including data centers. At the time, Haydon was a 35-person operation, but we earned the trust of the fab manager based on our ability to stay flexible, deliver with urgency, and manage high-stakes complexity.

The project included a 110,000 SF semiconductor manufacturing facility and a 4,000 SF Class 10 clean room. Subsequent phases added a 21,000 SF central plant, 6,200 SF liquid and gas storage and distribution facility, 15,700 SF support building, and two 24,100 SF Class 10 clean rooms—one as new construction and one as a technology conversion. Even as scope evolved, including a mid-construction change in wafer size, the team maintained schedule and cost control.

This project set the tone for Haydon’s commitment to technical excellence and responsiveness—qualities that continue to define our approach to data center and advanced manufacturing work today.
