In the heart of Rome’s historic centre, adjacent to Piazza Trinità dei Monti, the Biblioteca Hertziana has undergone major redevelopment. The complexity of the site, which is rich in archaeological remains, required a special structural solution: the new building is supported by a system of suspended beams designed to avoid any interference with the protected subsoil. At the core of this system is the Beam Floor, a 3-metre-high pre-stressed concrete (post-tensioned) box structure, composed of six main beams stiffened by four secondary reinforced concrete beams.

Due to the complexity and significance of this box structure, DIAMONDS was commissioned to carry out a series of targeted technical surveys and inspections, including:
