Quincy Apartments – 555 Bryant Street – Project Feature

The 555 Bryant Street development—also known as Quincy—is a 16-story mixed-use residential tower currently under construction in San Francisco’s SoMa district. Designed by Solomon Cordwell Buenz and built by Swinerton, the project exemplifies the intersection of architectural ambition and engineering precision. For structural engineers, it presents a compelling case study in high-rise concrete construction, façade integration, and the coordination of complex building systems.

Our Contribution

Aquinas Engineering played a vital role in the project by providing structural calculations for several key components that contribute to both the performance and aesthetics of the building. These included embeds, anchors, handrails, roof glass railings, storefront systems, punched windows, and screen walls. Each of these elements required careful attention to detail and close collaboration with other trades to ensure structural integrity and compliance with building codes.

Embeds and Anchors

Embeds and anchors are foundational to the structural integration of architectural and mechanical systems. At 555 Bryant, Aquinas Engineering’s calculations supported the installation of concrete embeds for façade systems and mechanical equipment, as well as anchors for screen walls, handrails, and storefront framing. These components, though often hidden from view, are critical to the building’s long-term durability and safety.

Glass Roofing

The rooftop amenity spaces and podium courtyards feature custom glass railings and handrails that blend safety with design. Aquinas Engineering provided load calculations in accordance with CBC and ASCE 7 standards, ensuring these elements could withstand lateral and impact forces. The team also detailed connections to concrete and steel substrates, coordinating with waterproofing and edge protection systems to maintain performance and visual clarity.

 

Punched Window

The ground-level storefront and upper-level punched windows are framed in aluminum and integrated into the concrete shell. Aquinas Engineering supported these systems with structural calculations for framing members and anchors, wind load analysis, and deflection criteria to ensure glazing performance. The façade’s distinctive sawtooth bay windows added complexity, requiring careful consideration of eccentric loading and thermal movement.

Screen Wall

The screen wall system, used for visual screening and mechanical concealment, was engineered to resist wind and seismic forces while remaining lightweight to minimize load on the slab. Aquinas Engineering’s calculations integrated these walls with rooftop and podium-level architectural features, balancing aesthetics with structural performance.

Conclusion

While the spotlight often shines on the core and shell of high-rise buildings, it’s the detailed structural elements—embeds, anchors, railings, and façade systems—that bring the architecture to life. Aquinas Engineering’s contributions to 555 Bryant Street reflect the importance of precision, collaboration, and deep structural insight. This project stands as a testament to how thoughtful engineering can elevate both form and function, and we hope it inspires fellow engineers to continue pushing the boundaries of what’s possible in urban construction.
