Mapeamento das Fundações de João Pessoa com relação ao porte, localização e data de Conclusão dos edifícios.

Abstract

This paper was produced with the aim to map in a practical way, in the city of João Pessoa, the types of foundations chosen for buildings, in the main zones of verticalization in the city, with different locations, size and completion dates, so that a comparative analysis can be carried out, and thus, conclusions can be reached regarding the technological advances in the execution of foundations, preference of a certain type of foundation for buildings in different geotechnical locations, disuse and tendencies of foundation techniques over the years , etc. For this, buildings were chosen to be part of the study according to the main vertical growth regions of the city, as well as the area of activity of the large construction companies, with the mapping of the location of the bulding done by satellite. After that, a database of the buildings was developed, including information about the foundation of each of them, which were obtained with the aid of visits to ENGEOBASE - Engenharia de Fundações LTDA, to the main calculators of the city of João Pessoa, mainly those that have been working in the business since the beginning of the city’s verticalization, and also by contacting the constructors of the cataloged buldings. Finally, comparing the information through graphs and tables, obtaining correlations between the adopted foundation solution (direct, deep or mixed and its most usual models chosen in João Pessoa), the size of the building (location of the building, reflecting the geological formation to which it is inserted, which may be, for the case of João Pessoa, the marine terrace or Barreiras formation) and its completion year (reflecting the feasibility and accessibility of different foundations over time).
