The present paper deals with the subsidence problem arising in buildings of a neighborhood of Sallent (Barcelona, Spain) due to the excavation of an old mine tunnels. The necessary preventative measures required to deal with this problem prior to the final evacuation of the buildings led to the thorough understanding of their technical characteristics, their damage, and the dynamics of their cracks and their safety conditions. The article presents the methodology that was followed for decision making. The data obtained allow us to know on one hand, the relationship between the movements of the soil and the buildings, and on the other, to contrast the actual behavior of the buildings due to the stresses generated by the differential settlement in their foundations.
