Context
CIDECO carried out a structural diagnosis of the Tapponnier Hall for SNCF to assist the project owner in defining rehabilitation options.
The building, constructed in 1929 as a freight terminal, was designed following the principles of François Hennebique’s company, a pioneer in the development of reinforced concrete in the early 20th century.
