Geotechnical Solution for the Foundation Soil of the 7 Towers of the Villa Panamericana

This geotechnical report offers an exhaustive analysis of the geotechnical solution implemented for the foundation bases of the 7 towers of the Villa Panamericana complex. These towers, made up of three 19-story towers and four 20-story towers, were built as part of the 2019 Pan American Games project, in the Villa el Salvador district of Lima, Peru. It should be noted that this project presents structural challenges of an unprecedented magnitude in land of this type in the country, due to the characteristics of the soils of wind origin. To carry out the analysis, an investigative collaboration was carried out between several companies specialized in geotechnics. Various field exploration techniques were used to obtain precise information on the characteristics and behavior of the terrain. The results indicate the presence of granular soils of the clean sand type, poorly graded, slightly humid and with very little amount of fines, whose consistency, of these transported deposits, varies from loose on the surface, to moderately dense and dense at greater depths. Without the presence of groundwater levels. Different alternatives were evaluated to solve the problems in the support base, and finally it was decided to replace the soil with layers of hydraulic concrete at a depth of 3 m and superimpose a foundation plate. This innovative solution was chosen due to the magnitude of the structure, time constraints and the characteristics of the soil present.
