<p><strong>Abstract.</strong> The use of steel technologies in Italian architecture still represents an unexplored field of research, characterised by limited and fragmented episodes that reveal important design experimentations and relevant architectural results of the 20th century. For this reason, the aim of the research consists of defining a HBIM methodological approach addressed to the study of modern steel architectures, considering their specific features and their hybrid constructive nature. Indeed these buildings are often characterized by a high level of industrial production of building components merged with the recovery of a craftsmanship tradition, particularly appearing at the scale of structure and envelope details. The balance between standardization and traditional techniques in production processes, leads to the definition of a HBIM method composed of three steps: an operational tools for existing buildings of 20th century made of steel that could support the construction of building digital archives, the organisation of maintenance programs and possible transformative actions, avoiding the loss of this heritage sometimes caused by bad interventions that deeply change original and valuable features of these architectures.</p>

With the increasing focus on the construction sector (e.g., following the European Green Deal initiative) with the aim to reduce emissions by 55% by 2030 (compared to 1990 levels), as well as achieve full decarbonisation by 2050, the built environment remains a strategic domain for the R&I (Research and Innovation) agenda. Indeed, the building and construction sector is the main contributor to greenhouse gas emissions (39% of global emissions as of 2018), highlighting the need to start a process of decarbonisation of this sector. The overall reduction in the environmental impact of building materials is achieved by establishing sustainable continuity between the end-of-life phase of the building and the production phase of individual building components. In particular, with reference to the end-of-life phase of the building (BS EN 15978: 2011), the Minimum Environmental Criteria foresee the preparation of a plan for the disassembly and selective demolition of the building, which allows the reuse or recycling of materials, building components and prefabricated elements used. According to the guidelines of a low-carbon construction design, which takes into account a circular economy, the following thesis deals with a methodological proposal to study “dry” construction systems (wood and steel). In particular, the study intends to reach the development of such an elaboration by carrying out an assessment of the environmental impact of a process of selective disassembly and demolition of steel building systems. The model is developed on the basis of a reading of the level of sustainability of emblematic case studies, appropriately identified, i.e., ‘quality’ architectures, built with ‘dry’ (steel) building systems.

Based on the octree decomposition method and the hierarchical bounding boxes method, an accurate collision detection algorithm integrating spatial decomposition and spatial occupancy is proposed. Through an example of a three-tiered steel building, a quantitative analysis approach to roughly judging the relative efficiency is obtained by comparing the algorithm with several others. The analysis results indicate that the proposed integrated algorithm is applicable to accurate collision detection of building structures. In addition, focusing on two special collision detection issues in construction projects, namely collisions of pipeline projects, and collisions between dynamic construction machines and building components during construction process, the integrated algorithm is also improved according to the corresponding characteristics. A real construction project of a medical building is used to verify the feasibility and effectiveness of the improved algorithms. The results illustrate that the improved algorithms can solve the existing problems and provide satisfied efficiency.
