TRU by Hilton
The Project
A four-story TRU by Hilton hotel designed with traditional light wood-framed walls and roof, paired with steel framing at the ground level for large, open lobby areas. This hybrid system demonstrates how thoughtful engineering and coordination can make wood framing not only practical but highly effective for mid-rise hospitality projects.
The Challenge
Many believe hotels should never be wood-framed — arguing that block or steel structures are safer and more durable. However, with the right engineering plan and compliance with building codes, wood can perform exceptionally well, even in demanding environments like Beaufort, SC.
For this TRU by Hilton, the design team had to address seismic and soil conditions that introduced the risk of liquefaction, while also achieving Hilton’s open, modern layout. The challenge was to maintain safety, speed, and economy proving that wood could meet structural and fire code requirements for a four-story hotel.
The Solution
The project employed a hybrid structural system integrating wood framing with steel components. Wood shear walls provided lateral resistance, while steel framing over the lobby allowed for wide, open spaces without excessive deflection.
Several smart design strategies were key:
-
Safety first.
The structure was engineered to handle both gravity and lateral loads using wood shear walls and a robust foundation system designed for seismic stability. -
Efficiency through material choice.
Heavy timber framing was used for the elevator shafts, eliminating the need for masonry. This decision reduced both cost and construction time by removing an entire trade from the project. -
Fire safety compliance.
With Type 5B construction, the four-story height represents the upper limit for light-framed wood structures. The building was fully sprinklered, satisfying fire and life safety codes. While fire protection design lies with the architect, the structural system was fully compatible with these safety measures. -
Community impact.
Beyond structure, the TRU by Hilton serves a greater purpose providing accommodations for Marine families visiting nearby Parris Island. The project not only strengthens the local economy but also supports the broader military community.
The Improvements
Several structural refinements enhanced both safety and constructability:
-
Integrated steel and wood systems to balance economy and strength.
-
Implemented seismic soil mitigation through improved ground densification and engineered foundation design.
-
Utilized optimized shear wall layouts to ensure lateral resistance without compromising floor plan flexibility.
-
Collaborated closely with the contractor to maintain Hilton’s construction timeline and budget.
The Results
The completed TRU by Hilton stands as proof that wood-framed hotels can be strong, safe, and efficient when carefully engineered. The project achieved cost savings, faster construction, and full code compliance while maintaining Hilton’s design standards and delivering long-term resilience.
