The grandstand steel structure at the National Stadium of El Salvador has been successfully completed, marking a key construction milestone.

This project is located in San Salvador and covers approximately 57,500 square meters. It features a modern 50,000-seat professional football stadium, with supporting facilities for spectators, athletes, competition management, and media.

The grandstands use a steel frame system with buckling-restrained braces (BRBs). With about 9,700 tonnes of steel, the structure is complex and required precise lifting and alignment.

To ensure accuracy, the team used BIM to create high-precision 3D models and implemented a method combining ground assembly of large units, high-altitude installation, and synchronized unloading—improving both efficiency and safety.

The team also addressed challenges in constructing large ground-supported intersecting trusses and a single-layer grid shell, achieving seven new technical innovations that will support future projects.
