Abstract

The two large-scale earthquakes that occurred on September 7 (Mw 8.2) and 19 (Mw 7.1), 2017 in Mexico left 2,340 damaged architectural heritage buildings throughout the country. Due to the large amount of architectural heritage buildings damaged, the government department responsible for protecting the architectural heritage and the practitioners specialized in conservation was overwhelmed. Therefore, it was necessary to incorporate practitioners who are not specialized in conservation, first to attend the emergency works and later into structural intervention works. In this way, this paper presents some examples of emergency work, as well as intervention proposals that have been inadequate. The common errors observed in emergency works are discussed, as well as the application of erroneous or inadequate concepts in intervention proposals. Comparison with correct intervention works are also presented.
