BIM application in infrastructure project in the reuse of historical cities

The evolution of the Smart cities in the old town is one of the most important aspects developed by the European Municipalities. To develop a smart city in an old town, the municipality must design new infrastructures for transports, subway lines, underground parking areas and, furthermore, design new technological systems for lighting, heating-cooling and other services. The possible interferences between the historical buildings and existing infrastructures during design, construction and for the facility management are well known. In this way, the BIM Modelling of the existing and old town help designers and owners to envelope new projects to re-green the cities or to transform them. The example shown in this article is about the new metro line and stations of Copenhagen. In this work, a process to envelope the BEP for the survey and the base model to develop the construction and evaluate the interferences with the existing buildings is suggested. A complete BEP may help to envelope an integrate model to represent: - 3D for the modeling and analysis of the city, MEP, Structural and architectural modeling for the new metro station. - 4D for the association of all the model elements to a specific temporal phase during construction, for the coordination of the several subcontractor companies regarding excavation works, tunneling, casting, reinforcement and electromechanical works, for both stations and tunnels. - 5D for the computing and estimation for all the works. - 6D regarding the sustainability. - 7D regarding the underground facility and monitoring management.
