Modular Infrastructure
Permanent, Factory-Built Structural Platforms for Critical Facilities
Whitmore Steel supports modular and prefabricated construction through high-tolerance structural steel assemblies, platforms, and frames fabricated under controlled shop conditions. Built on our AISC-certified fabrication and erection platform, these systems support accelerated schedules, improved coordination, and reduced field risk for permanent modular infrastructure.
What We Build
Whitmore Steel provides structural steel scopes tailored for modular and prefabricated construction, including:
- Load-bearing structural frames for modular buildings
- Interstitial platforms and service-level steel
- Equipment and mechanical support structures
- Transport and lift ready steel assemblies
- Bolt-up, installation-sequenced steel systems
All assemblies are detailed with dimensional accuracy, transport considerations, and installation sequencing in mind
Structural Steel First
Self-Performed Structural Steel. Fabrication-Led Modular Execution.
Whitmore Steel’s modular approach is built on self-performed structural steel fabrication—driving dimensional control, quality consistency, and predictable installation across the modular process.
This approach enables:
- Earlier fabrication and controlled release sequencing
- Predictable connection geometry
- Cleaner coordination with MEP systems
- Tolerance control verified under Whitmore's AISC-certified quality program
- Reduced risk during installation on constrained or operating sites
How We Deliver Modular
Whitmore Steel operates under a delegated-design modular delivery model:
Structural steel fabricated and assembled by Whitmore Steel
Structural Engineer of Record engaged through established third-party partners
Factory Acceptance Testing (FAT) performed prior to shipment
No field modifications without Whitmore Steel approval
Ideal Applications
Whitmore Steel modular assemblies are best suited for:
- Healthcare facilities and hospital expansions
- Mission-critical and data center environments
- Education and institutional buildings
- Industrial and utility infrastructure
- Projects where schedule certainty and site constraints are critical
* Fabrication nationwide | Erection executed regionally through project-specific staffing aligned with GC delivery plans
FAQ
How does Whitmore Steel deliver modular projects?
Whitmore Steel fabricates structural steel modules and assemblies in our AISC-certified facility and delivers them as installation-ready systems. Modules are coordinated with project teams, verified prior to shipment, and erected on-site to integrate with the permanent structure. These services extend Whitmore Steel’s long-standing structural steel fabrication and erection experience into adjacent applications requiring tighter coordination and controlled execution.
What modular applications does Whitmore specialize in?
Hospitals (patient rooms, wings), education facilities, data centers, mission-critical buildings, and office additions—where speed and minimal disruption are critical.
How does Whitmore ensure seismic compliance in modular?
All modules are designed with AISC-compliant steel framing and seismic detailing, backed by EOR partners to meet or exceed CBC (CA) and IBC (AZ) requirements.
What schedule and cost benefits can project teams expect?
Off-site fabrication enables earlier release of structural scope, reduced site congestion, and more predictable installation—often accelerating schedules compared to conventional stick-built steel.
Can Whitmore integrate modular with traditional or existing construction?
Yes. Whitmore Steel coordinates connection geometry, tolerances, and sequencing to support hybrid projects involving existing structures or conventionally built systems.
Does Whitmore offer design-build services for modular projects?
Yes—Whitmore Steel operates under a delegated design or design-assist model, collaborating with Architects and Engineers of Record engaged by the owner or GC.
Where does Whitmore Steel perform this work?
Whitmore Steel fabricates structural steel assemblies in AISC-certified facilities and executes erection through regionally aligned project teams, coordinated with GC delivery plans and project requirements
