Abstract

Over the past decade, the building information modelling (BIM) approach has increasingly been used in both professional practice and research relating to the fields of civil and structural engineering. Indeed, it has been adopted across the globe, with some governments demanding its use in public projects involving bridges, tunnels and railways, as well as for strategic facilities like hospitals and schools. In Europe, most countries comply with Directive 2014/24/EU of the European Parliament and of the Council on public procurements, which allows such clients to demand the use of BIM methodologies. Some countries, meanwhile, have decided to enforce digital delivery; for example, the United Kingdom has required the use of BIM in all government projects since 2016, while the Italian government published a timeline in 2018 mandating the use of BIM methodologies in all construction work by 2025. As a consequence, companies involved in the AEC sector are embracing the BIM approach by employing new tools and workflows, even though they face obstacles in relation to issues like training costs and time or low initial productivity. BIM-based workflows, innovative tools and collaboration platforms can be employed throughout the lifecycle of an asset, and have been the catalyst for innovation in the entire architecture, engineering and construction (AEC) industry. However, the BIM approach does not have its own agenda for research purposes only, but this has one in applied research with the purpose of aiding professional practice. Thus, this thesis will address the use of BIM in structural engineering not for the sake of the research itself, but with the practical intent of summarizing and presenting the current experience of the use of BIM in structural engineering and then contributing to expanding knowledge about the possible uses of BIM in this regard. This thesis proposes innovative processes for the lifecycle information management of information that refers to the discipline of structural engineering. The proposed processes are based on the BIM approach, an information management framework that allows to standardise information flows using processes that implement tools such as BIM-authoring software, BIM tools and collaboration platforms. In detail, the BIM-based processes here proposed are in the number of three and refer, respectively, to the authorization phase, the testing and closeout phase, and the operation and maintenance phase of the lifecycle of a facility. A further novelty of this work is investigating the use of the open format industry foundation classes (IFC) in the processes that refer to the authorization phase and the operation and maintenance phase, and the use of blockchain technology in the testing and closeout phase. The first aim of this thesis, therefore, is to start bridging that gap by 1) providing the first state-of-the-art on the use of BIM in structural engineering. Additionally, this thesis is original in that it addresses the production, management, and storage of information that pertains to structural engineering. Accordingly, this work aims at: 2) Proposing an open BIM-based process for the application for seismic authorization, in Italian 'autorizzazione sismica' (authorization phase). 3) Proposing a proof-of-concept for the integration of blockchain technology and smart contract into information flows among common data environments (CDEs) in the construction process of structural systems (testing and closeout phase). 4) Proposing an open BIM-based process for the operation and maintenance phase of structures.
