The Mountain West is having a moment. Land availability, favorable tax structures, cooler ambient temperatures, and improving power infrastructure have made Utah and its neighbors a serious destination for data center investment. Projects are breaking ground at a pace the region has never seen. And some of them are already running into trouble.
Not because the locations are wrong. Because structural engineering decisions made early are creating problems that compound expensively down the line, a pattern often seen in projects involving Utah data center contractors during early-stage coordination and build planning. So where exactly do most of these early decisions start to quietly go off track?
Underestimating Seismic Load Requirements
Utah contains several active fault systems capable of producing significant seismic events, and yet seismic load calculations still get treated as a compliance formality on too many projects.
Data centers carry concentrated loads that seismic design must genuinely account for:
- Dense server rack configurations across large floor plates
- Heavy cooling infrastructure including chillers and piping systems
- UPS equipment and battery banks concentrated in specific zones
- Raised flooring systems that distribute load unevenly across the slab
A structural frame built to minimum code thresholds rather than operational reality passes inspection and still performs poorly under stress. Seismic design in this region demands real engineering attention from day one, not a checkbox near the finish line.
Getting the Floor Loading Wrong
The structural slab gets designed around standard commercial loading assumptions. Then the mechanical and electrical teams arrive with equipment specifications that exceed those assumptions considerably. It happens on project after project.
By that point, reinforcing the slab costs multiples of what a correct early design would have required. Structural engineers and equipment specifiers need to share the same conversation before foundation drawings are ever finalized. Waiting until later is not a scheduling convenience. It is an expensive habit.
Ignoring Thermal Expansion in Steel Framing
Mountain West climates swing hard between seasons. Temperature differentials between a Utah summer and a Utah winter can exceed 100 degrees Fahrenheit, and steel accumulates stress at connections and joints over time as it expands and contracts with those shifts.
Expansion joints, flexible connections, and material selections that account for this thermal range are not optional finishing details. They are long-term reliability decisions. Facilities that cut corners on thermal provisions start showing cladding failures and connection fatigue within a few years of opening.
Miscalculating Roof Load for Mechanical Equipment
Cooling towers, air handling units, condenser arrays. Data center rooftops carry serious mechanical loads, and the structural steel required to support them adds up faster than early-stage estimates typically reflect.
Projects that treat roof load calculations as a late-stage coordination item face the same outcome with uncomfortable regularity: expensive redesign, delayed schedules, and occasionally compromised structural performance in the finished building. The mechanical layout needs to inform structural design from the beginning. Not the other way around.
Underdesigning for Redundant Infrastructure Pathways
Structural engineering in a data center extends well beyond the building envelope. Cable trays, pipe chases, and conduit runs for redundant power and cooling systems all require structural accommodation that turns costly and disruptive when retrofitted after the fact.
Facilities built without adequate pathway provisions end up with:
- Compromised ceiling heights that disrupt airflow management
- Penetrations cut through structural members after construction closes
- Retrofit costs that dwarf what early coordination would have required
- Operational constraints that directly affect tier certification outcomes
Treating the Building Pad as a Secondary Concern
Expansive soils, caliche layers, variable bedrock depth, freeze-thaw cycling. Site preparation in the Mountain West presents challenges that differ meaningfully from most other regions. Projects that rush geotechnical investigation to accelerate the schedule sometimes discover, well into construction, that the ground beneath them behaves differently than the assumptions driving their design.
Differential settlement in a data center is not a manageable inconvenience. It affects raised floor levelness, equipment alignment, and in serious cases, the structural integrity of the building itself.
The Cost of Getting It Right Versus Wrong
Structural corrections mid-construction range from disruptive to project-threatening. The decisions that cause the most damage are almost always the ones that seemed premature or minor to address during early design phases, especially in complex builds like an SC data center. The projects that finish on time and perform as intended share one defining trait. They treated structural engineering as a genuine first-order priority rather than a background discipline.
Everything else followed from that decision.
