Residential/Single & Multi-Family Homes – The Ayer

The Ayer is a 45-story residential tower completed in December 2023 that adds a bold presence to the Seattle skyline, with a geometric façade inspired by Pacific Northwest tectonics. The cast-in-place concrete structure uses post-tensioned slabs and a shear wall core to resist seismic and wind demands, achieving long spans with 12-foot perimeter cantilevers. The concrete core was designed using Performance-Based Design, including optimization of wall thickness, material properties, and coupling beam behavior. Steel Fiber Reinforced Concrete coupling beams replaced traditional diagonal reinforcement, simplifying construction and accelerating the schedule. Sixteen vertically aligned columns from foundation to roof eliminated the need for transfer beams, a rare approach in high-rise construction. Sustainability measures included high-strength reinforcement and Type 1L Portland Limestone Cement throughout the structure, reducing embodied carbon by more than 450 tons of CO₂.
