KPFF provided structural engineering services for the Hassalo on 8th mixed-use development in the Lloyd District. The project consists of over a million square feet of new construction, including apartments, retail, and below-grade parking. Occurring on a large “superblock” site in NE Portland, the structures include three residential buildings; the 5-story Elwood, 6-story Velomor, and 21-story Aster residential tower. The low-rise buildings are Type V and III wood construction over Type I concrete podiums with the tower consisting of concrete flat slabs and core walls. In addition to wood and concrete, there was also an extensive quantity of both structural steel and concrete masonry to complete the project which required many trades to be working on site during the overall construction duration. Large exterior plaza spaces interconnect the buildings at the ground level with elevated concrete bridges and walkways. The ground level podium slab interconnected all of the buildings and included large exterior plaza spaces, a private street (NE Hassalo), and a pedestrian walkway, “Waterstreet”, with elevated concrete bridges and walkways. The buildings and plaza occur over a 3-level parking structure that can accommodate up to 1,200 vehicles. The project includes sustainable features such as rainwater harvesting and treatment, on-site wastewater treatment and re-use, and access to public transportation.
