A Historical, Yet Modern Structure: Cross-laminated timber engineered into the decking
Named after the famous triangular shaped building in New York City, this up-and-coming six-story office building in north Portland will feature cross-laminated timber (CLT) floors supported by glulam beams, topped with reinforced concrete. The two-way span properties of CLT will be used to accentuate alternating exterior “boxes” at the corners of this three-sided building.
DCI developed the special framing systems for the building. Post-tensioned concrete slabs will separate the lower level retail space with heavy timber framed office space. The lateral system will consist of conventionally reinforced concrete shear walls. Flatiron PDX is scheduled for completion in early 2018.
- CLT accomplishes the building’s distinctive two-way, “floating” box cantilever design at the corners of the building.
- CLT achieves the 3-hour fire rating requirements.
- Partial below-grade parking level.
