Abstract

Digitising public administration (PA) is essential for enhancing efficiency, transparency, and traceability in public procurement management. This document presents an integrated model that amalgamates building infor-mation modelling (BIM), digital twins (DT), IoT sensors, smart contracts, and blockchain technology to automate the contract lifecycle, encompass-ing technical verification to performance settlement, in accordance with the National Recovery and Resilience Plan (PNRR) and the new Public Con-tracts Code (Legislative Decree 36/2023). The goal is to test a digital system that can work with other systems and replace manual tasks with ones that are automated, clear, and easy to track. The concept was implemented on a photovoltaic system at the University of Salerno, where a digital twin, uti-lising real-time data, was synced with a BIM model in the IFC format. The operational data, verified against established technical thresholds, activates smart contracts on the Ethereum blockchain, automatically authorising the execution of payments or status records. The results indicate a substantial decrease in technical intervention duration, enhanced monitoring precision, and heightened trust among the involved parties. The model shows that it can be used again and again for large and complicated public infrastructures. It also creates a foundation for unified digital management, which makes it easier to change the way government works and bring new technologies into the public sector.
