This article presents the design process and structural analysis for Halls 3, 4, and 6 commissioned by Fira de la Gran Vía in Barcelona. Its objective is to document the complete development of a real structure—from the initial briefing to final execution—highlighting key decisions related to cost, quality, construction speed, and standardization. Rather than simply describing the finished building, the article compares alternative solutions considered at each stage and explains the rationale behind the choices made. Close collaboration between the architectural and structural teams has resulted in a cost-effective solution that has remained relevant twenty-five years after completion. Each structural component is examined in detail, considering its behavior, preliminary sizing, fabrication, transportation, and rapid on-site assembly, all essential under the client’s demanding schedule. It also describes how specific structural details were resolved under project constraints, including instances that required unconventional approaches. Finally, it discusses the role of prestressed longitudinal frames as a strategy for reducing steel consumption. This article underscores the value of integrated architectural and structural thinking in shaping the building from the ground up.
