Cálculo del porcentaje de hundimiento en construcciones mediante tecnología BIM y vehículos aéreos no tripulados en un barrio del sur del DMQ

Abstract

Currently, subsidence in the city of Quito occurs frequently, in the Solanda sector presents a high degree of vulnerability due to anthropogenic and natural factors, which is why this study aims to link the BIM and AUV methodology to generate a predictive model to be used as a tool for risk management in the face of this problem. The methodology applied was based on the collection of theoretical background, observation and analysis of the study area, then three surveys were conducted with a referential GPS and AUV in the pre selected control points to achieve an accurate georeferencing of the area, on the other hand, the elevation variable of the control points was analyzed during a period of four months, and a combination of different software for the generation of a point cloud was performed. The results obtained mainly from the software mentioned in the methodology were a predictive ARIMA model that considered only the elevation variable to calculate the percentage of subsidence. As for the three-dimensional model, the Revit program made it possible to visualize a three-dimensional point cloud that resembles the study area.
