Abstract
Abstract. Even in the context of increasing digitisation, the construction sector continues to be characterised by redundancy, multiplication and, at the same time, a lack of transparency and disaggregation of data and information, leading to ineffective management of the time, costs and quality of the project life cycle. This paper shows the results of the development of an ICT application, TRL 4-5, based on the integration of Building Information Modeling and blockchain technologies and designed to foster digitisation processes in the supply chain, in the direction of greater transparency of information flows, knowledge-based organisations and decision-making processes based on unambiguous ordered data. Starting from a broader industrial research collaboration, the project involves a university spin-off, companies operating as system integrators and leaders in the customisation of BIM solutions for the Italian construction market. The project, launched as part of a network of public and private stakeholders established in 2019 and developed between September 2020 and March 2021, is part of a territorial development strategy financed by European Structural Funds. As a result, the research output is a prototype of ICT tool, which implements the Common Data Environment, CDE, making the life cycle management unambiguous, certified and clear. In this regard, the results of the project are meant to respond to the supply chain's need to encourage the digitisation and automation of processes, as well as to encourage the acquisition of unambiguous data, according to a big data approach.
Highlights
The use of Building Information Modeling (BIM) tools is demostrating that it is feasible to organise knowledge according to integrated digital information systems, supporting all phases of the construction life cycle
Following the example of the digitisation process kicked off by the United Kingdom in 2009, a number of Member States have taken diversified actions to encourage the adoption of BIM tools, which are recognised as the most effective driver towards a more pervasive digital transformation of the sector [Daniotti, 2020]
A similar result was pursued with the introduction of the new Public Procurement Code, Ministerial Decree 560/2017, which made the use of BIM tools mandatory for progressive works amount thresholds; currently, the compulsory requirement corresponds to contracts with a value of 15 million euro or more. [D.M. 560/2018] the described scenario has encouraged a general push in the sector towards the use of Building Information Modeling tools regardless of the mandatory thresholds and with reference, in particular, to intervention on the built heritage
Summary
The use of Building Information Modeling (BIM) tools is demostrating that it is feasible to organise knowledge according to integrated digital information systems, supporting all phases of the construction life cycle. Between November 2018 and December 2020, more than 110 BIM tenders were published by the Agenzia del Demanio for a value of more than 200 million euro. Among these ones, fiftyfive tenders were destined for: architectural, structural and plant engineering survey, diagnostics, and technical and economic feasibility plan for the assessment of the seismic vulnerability of the built heritage. And increasingly the number of tests of blockchain technologies applied to the construction sector, integrated with BIM technologies, show the growing interest of the supply chain in the innovations offered by this technology in order to respond to structural inefficiencies in the value chain
