Integrated Structural Response — A case study of blending structural systems and programming into a single solution.
The structural success of One Palm / Aloft Hotel Sarasota depended on combining several distinct systems into one coordinated solution. The existing concrete garage provided the base structure and established the controlling grid, capacity, and load-path constraints. Above it, the addition of three steel-framed floors offered a lighter and more adaptable way to expand the program, but it also required careful attention to column alignment, transfer conditions, lateral-force continuity, steel-to-concrete connections, and differential movement between materials.
Rather than treating the hotel, residential, parking, retail, and amenity components as separate structural problems, the project required an integrated approach. The post-tensioned concrete floors addressed repetitive spans, efficiency, and service coordination, while the steel expansion responded to weight, constructability, and the need to adapt new occupancies to an existing garage framework. Transfer elements, connection detailing, and lateral-force-resisting strategies became the link between these systems, allowing the divided program to function as a unified building.
Ultimately, the project illustrates how mixed-use urban construction often depends less on a single structural idea than on the successful coordination of multiple systems. By balancing the capacity of the existing concrete garage with the flexibility of new steel framing and the efficiency of post-tensioned concrete floor construction, the design team could meet the divided programming challenges of hospitality, residential, parking, retail, and amenity uses within a constrained downtown site. The result is an integrated structural solution in which each system supports the others and the overall building program becomes achievable.
