Presentation Summry

The lecture will deal with the controversy that arose over the effects of the construction of a tunnel in Barcelona, for the High-Speed train, on the Temple of the Sagrada Familia. The construction of the tunnel was considered by many as a great structural risk for the temple, as well as for the Casa Milà, both by the famous architect Gaudí. The preventive measures taken, the monitoring implemented, the structural modelling, the control carried out and the results obtained will be explained. It is an example of how to address the risks of a construction which could affect UNESCO World Heritage.
