The average incidence of design variation and unexpected events related to the delivery of construction sites is about 13% compared to project planning. The objective of this study is to lower this percentage to about 10–11%, using methodologies aimed at configuring effective digital management strategies. The main purpose is to enhance process efficiency and optimization of construction management strategies, as BIM-based digital management approaches allow to predict unforeseen events, reducing negative variation in time and costs.

The proposed application case concerns an applied methodology conducted on a 35,000 m² historical building renovation project, in a central urban context of Rome, owned by a public institutional real estate company.

The implementation of the proposed BIM-based digital information management strategies allowed to enhance efficiency in site management, reducing delay …
