THE ARCH AT HAYWARD FIELD
Nicole Giustino, August Lehnert, & Max Moore
The approach to this project was to rethink the design of a traditional grandstand and reﬂect the studio’s focus material, mass timber. The design challenge was to create something iconic yet, humbly frame Hayward Field’s historic East Grandstands. These initial ideas and approach lead to the ultimate design proposal: a 400’ mass timber arch. Resulting in better sight lines and avoiding any characteristic grandstand issues of deflection, this awe-inspiring structure, if constructed, would be the largest timber arch in the world.
With a structural system analogous to a bridge, this 400’ arch is rooted in four concrete abutments that stabilize this glulaminated system. Moment base connections link five glulams to each abutment and transfer loads axially down to the foundation of this athletic facility. Each glulaminated beam is divided into 60-foot segments and designed to incorporate hidden moment connections for a seamless appearance. These 60-foot sections are the optimal size for manufacturing, transportation, and constructibility on site. The outer three arches on either side of the overall structure are primary structural members, providing gravity and lateral resistance. The inner four arches are secondary members and besides contributing to the aesthetic rhythm, they also provide lateral support in reducing wind and seismic loads. The arch is covered with translucent polycarbonate roof panels intended to protect visitors from Oregon’s weather.
The Arch is a structure that not only reﬂects the historic nature of Hayward Field, but also one that supports the great timber industry of Oregon. If constructed, it would become an icon for Hayward Field, the University of Oregon, and for the State of Oregon’s timber industry.
- Innovative use of material(wood) to develop an elegant solution to a functional problem.
- Very compelling idea which combines traditional with new state-of-the-art technology
