Accomplishes the survey of the most commonly types of foundations used in the construction work, in the last decades in the city of Belém-PA; defining its
characteristics, peculiarities, technical aspects of the its measurement, load capacity and, executive process. Identifies the type of the soil in which are laid with respective profile and geotechnical characteristics and divides the city into areas, mapping according to its geological profile; type of foundation; layer depth; executive process and, relative cost. The work is divided in four stages: the first one corresponds the literature review, regarding the study of the foundations, including the foundation historical development and soil mechanics
in the world, in Brazil and in Belém; geotechnical research with characteristics of the soil in the area of Belém and, study of the Geographical Information Systems GIS. The second stage involving technical survey in construction
and design companies, for development of database concerning the foundations used in the city. The third, to relates the ordination and technical analyses of the collected data and, the fourth consists on the writing of the final text and the elaboration of the city maps, based on the Geographical Information Systems GIS, in scale 1:10.000, concerning the type of foundation; the geotechnical profile of the soil; the soils kind and the executive process; the probable foundation depth and, the relative cost of the foundation in relation to the total of the work.
