Guam has extremely stringent seismic and wind requirements that include maximum height limitations for certain structural systems. The majority of hotels in Guam are constructed using concrete floor slabs braced for lateral seismic and wind forces with concrete cores located at the buildings elevator and exit stair cores. The current building code in Guam, however, no longer permits this type of structural system for taller buildings unless independent moment-resisting frames are added or a more sophisticated Performance-Based Design process is followed. The addition of moment-resisting frames on the exterior of the building is not only expensive, but it also reduces the size of window openings and the breathtaking views of the Pacific Ocean. As a result, The Tsubaki Tower is the first project in Guam constructed using a Performance-Based Design.
In addition to being structural engineer of record, BASE also provided building code-required special inspections and material testing services. This allowed for seamless coordination between the design and construction of the primary structure.
