The viaduct over the Polcevera River constitutes a fundamental point for the connections and transport of Genoa, of Liguria and of Italy as a whole, constituting the terminal section of the A10 motorway limited, on the east side, by the junction with the A7 (Named Genova Ovest) and, on the west side, by the tunnel embankments leading to the junction named 'Aeroporto'.

The new San Giorgio bridge has an important technological content in order to enhance the architecture of the work and its environmental sustainability in terms of energy, so as to ensure high levels of road traffic safety and maximum durability of the structures and facilities themselves.

A BIM (BUILD INFORMATION MODELLING) PROJECT

In the executive design phase, Italferr has implemented the BIM model in the activity coordination processes by exploiting the potential of an ACDat (Data Sharing Environment), capable of managing the flow of interdisciplinary data guaranteeing their uniqueness and traceability, valid for infrastructure-type projects. The information model, therefore, acts as a connecting element between the first, temporally limited phase of design and definition of the work and the second, more complex phase of implementation and operation, maintenance and management of the structure.

SOLUTIONS IMPLEMENTED
Drafting of an information management plan (pGI) to establish from the outset the operational methods and contents of the BIM information model for the new viaduct.
Establishment of a shared working environment to facilitate the exchange of data and information among different stakeholders.
Development of a federated model in which to assemble specialised models with extreme precision and dynamism.
The use of a computational modelling system in an innovative way compared to the standard to ensure versatility and timeliness in realigning the model to any design changes.
Development of scripts for optimising and automating time-consuming manual processes.
Dimensional and geometric surveys to ensure the correct arrangement of elements in space, adding value to the work in terms of consistency and construction feasibility.
Association of the work program to the digital model, simulating the construction phases of the work to identify a priori workings and situations with particular criticalities.
Production of a digital model complete with all its parts to allow the development of a product of high visual impact, facilitating the client's pre-viewing and thus allowing clear and comprehensive communication between the parties.
Establishment of a basic information model for the subsequent stages of implementation and operation, complete with all useful information for the organisation of maintenance.
