Structural Design Differences in Off-Site Construction

By August 12, 2025August 14th, 2025No Comments

Many Epsilon Off-Site Construction Central Utility Plants (CUP) look very similar on the outside, but reviewing internal components can reveal a lot about critical project specifications. The Epsilon engineering and production teams recently worked on two CUP systems that have similar performance specifications, but very different structural requirements.

In this example, the two structural systems represent dramatically different design requirements. One is for an extremely high seismic zone, while the other is for an area with relatively low seismic requirements – but very high hurricane-driven impact resistance. Each necessitates an entirely different approach to the overall enclosure rating.

Looking at the photos below – can you tell which module is going to each area?

These projects highlight the 25-plus years of design and manufacturing experience at Epsilon – demonstrated, successful expertise designing and building modular CUP systems that adhere to one of the principal tenants of the real estate industry: Location. Location. Location.

Successful OSC partners have the practical engineering know-how to properly configure a system for the install location – whether on the seismic West Coast (with robust vertical I-beam supports), or hurricane-prone Southeast (with standard vertical tube steel configured to support specially-rated enclosure walls encapsulating the modular structure).
