Description
The digitalization of the construction sector is a major driver of innovation in Europe, as shown by the increasing adoption of Building Information Modeling (BIM). BIM implementation advances at different speeds: countries such as Denmark and Finland have long established requirements, while others, including Italy, are still consolidating their processes. In Italy, Ministerial Decree 560/2017 and the new Public Contracts Code (Legislative Decree 36/2023) make BIM mandatory from January 1, 2025 for public works exceeding 2 million euros. The objective is to improve transparency, quality, and control over public works while reducing inefficiencies and managerial risks. The private sector increasingly views BIM as a competitive asset enhancing accuracy, coordination, and overall project reliability. Within this framework, the Open BIM approach, based on open and non-proprietary standards, is essential for effective interoperability among stakeholders. The IFC (Industry Foundation Classes) format remains the international reference for structured and cross-disciplinary information exchange, ensuring continuity across the building lifecycle. This article examines the role of the bSDD (buildingSMART Data Dictionary), a tool designed to standardize concepts, properties, and classifications within information models. In building acoustics, a dedicated bSDD could offer significant benefits by harmonizing national and international standards, integrating performance requirements directly into IFC models, and supporting automated verification processes. Standardizing acoustic parameters such as sound insulation, sound pressure levels, and flanking transmission would enhance data consistency, regulatory transparency, and communication among designers, verifiers, and contractors. Integrating BIM methodologies and classification tools like the bSDD supports the development of an interoperable information ecosystem aligned with evolving European regulatory needs.
