The IF CRASC congress series originated from the institution of a second level Master programme (post-graduate programme) on Forensic Engineering at the University of Naples Federico II, Italy. Such a Master programme was the first one in Europe and includes subjects of both Civil and Industrial Forensic Engineering. Beside the traditional sector of Structural Forensic Engineering (mainly focused on failures and collapses), in the last years academics, professionals and public institutions have shown a growing interest not only in legal issues of engineering practice (e.g., procedures and responsibilities), but also in forensic fields of Industrial Engineering and Information Technology. This led to an extension of the topics covered by past Congresses on Collapses, Reliability and Retrofit of Structures to additional sectors of Forensic Engineering. The outstanding success of the past IF CRASC Congresses, as well as of other initiatives promoted in Italy and Abroad on similar subjects since 2009, has allowed the Italian Association of Forensic Engineering (AIF) to organise the IF CRASC '15 Congress in Rome.
