- Description: Upgrading to 4 lanes of the Cassia road.
- Project components: Final design in BIM.
- Client: Regione Lazio
The upgrade to 4 lanes of the Cassia road is a project that involved the “ex novo” design of 32 km of road in a particularly valuable territorial area of high landscape, archaeological and environmental value and with tight territorial constraints.
Production through BIM-oriented workflows was brought up to speed in a short time. The initial implementation of the design methodology included:
- The definition of the responsibilities of the resources involved for the purposes of modelling and information management;
- The organization of workbooks functional to the characteristics of an ACData;
- The creation of component libraries and custom templates;
- A careful study oriented toward the optimization of interoperability processes
Grasshopper, whose only input data was the road surface. This has made the design system more slim, accurate, controllable, and rapid. The structures of the line works were integrated with the three-dimensional coordination sensitive terrain (DTM), road infrastructure and hydraulic interference model in order to solve very complex design problems in a simple way.
Models of the structures were the starting point for structural and environmental impact analyses and renderings. The entire calculation phase of the structures was carried out starting from the reports returned by Tekla Structures, to which a functional guise was found for entering the data in a dispatchable manner into the programs used by the quantity surveyors. Similarly, all graphic designs were produced automatically from the digital model. In light of this experience of designing through BIM-oriented workflows, it was found that;
- The optimization of work management;
- The minimization of design errors;
- The improvement of communication of design information;
- The ability to deal with highly complex design and geometric problems in a simple manner;
- The control of all elements and quantities constituting the infrastructure work for the purpose of techno-economic analysis
On the occasion of the 2017 Tekla BIM Awards organized by Harpaceas, one of the most prominent consulting firms in the Italian scene for expertise on BIM, the model of the structures of the Santa Giulia Viaduct was submitted, which turned out to be the winner.
Equally, the 4-Lane Adaptation Project of the Via Cassia was awarded in the infrastructure category during the 2018 DIGITAL&BIM Awards at SAIE in Bologna 2018.
