Located in the “Empowering Lives” district of Expo Osaka 2025, the United Arab Emirates Pavilion stands out as one of the most iconic national structures. It not only embodies the culture and identity of the UAE, but also showcases its technological vision and engineering-forward approach to shaping the future.
A key architectural and structural element of the pavilion lies in its imposing vertical columns. Far from being mere supports, these columns serve as integral components of the pavilion’s narrative language. Clad in date palm wood slats, they define six thematic zones within the space, creating both a functional framework and an evocative spatial experience. Their presence is crucial in determining both the structural performance of the building and the immersive journey offered to visitors.
RIMOND approached the project with a highly technical and engineering-driven mindset, implementing decisive structural modifications to ensure stability, safety, and constructability, while remaining faithful to the original design intent.
The initial concept proposed 178 columns made entirely of date palm wood, reinforced with metal rings spaced every 10 cm. However, in-depth analysis revealed critical issues related to structural calculations and long-term durability, especially given the structural load and support functions required of the system.
In response, RIMOND developed an innovative hybrid solution, integrating a circular steel core within each column. This steel insert provides the mechanical strength and structural safety necessary for real-world operational conditions. Meanwhile, the date palm wood was retained as an external cladding, preserving the traditional aesthetic and cultural symbolism.
In parallel, the frequency of the steel rings was optimized from one every 10 cm to one every 20 cm resulting in a significant reduction in the number of columns, from 178 to 90. This rationalization enhanced structural efficiency while simplifying prefabrication, transportation, and on-site assembly.
The outcome is a pavilion that seamlessly integrates advanced and sustainable engineering solutions with a strong architectural reference to Emirati tradition, while also honoring Japanese craftsmanship in wood construction. Natural materials such as wood and palm leaves are also used in interior and exterior flooring, contributing to both the coherence of design and the environmental quality of the entire structure.
RIMOND’s contribution illustrates how engineering can be the driving force behind architectural innovation, enabling the realization of complex structures that are emotionally engaging, technically high-performing, and environmentally responsible.
