SUMMARY:

The water present in aquifers has different uses in the Federal District (DF), including domestic supply, the service sector, industrial uses, mining, agriculture and recreation. With the increasing demand for fresh water and its withdrawal from aquifers, an active management of these water resources becomes necessary. The surface areas where precipitation allows water to infiltrate and be transported to the aquifers are called recharge areas. In the area of infrastructure, the use of BIM is on the rise and often associated with the use of GIS tools. The use of both technologies is usually referred to as GeoBIM. Industry 4.0 contemplates the innovations that impact the production processes of the current era, such as large databases, smart cities, machine learning, and the integration of BIM and GIS technologies themselves. The general objective of the dissertation is to characterize aquifer recharge areas in the Federal District (DF) from a geological-geotechnical point of view, with the support of Geotechnical BIM and GIS tools to allow decision making in monitoring and intervention actions. The work was guided from a GeoBIM Execution Plan (GEP), a new concept introduced in the elaboration of the dissertation aiming the standardization of BIM and GIS data. A suggested topic structure for the document was presented, with descriptions and applications in the context of the presente work. From the consolidation of a database for aquifer recharge analysis in DF, a multicriteria analysis with the hierarchical process analysis (AHP) technique was performed with the criteria in descending order of weights: fractured hydrogeology, precipitation, geomorphology, slope, pedology, water depth, lineament density , use and cover and roughness. A case study was conducted for a pilot area at FAL-UnB, according to the Progressive Detailing Methodology, with the refinement of the criteria used in the DF analysis with field surveys and IoT sensor data.  The cartographic products generated were compared with previous studies, which convergences were noted. From a data perspective, a proposed data standardization was proposed for the Guelph permeameter test, from the mapping of relevant information by the literature review. A Geotechnical BIM application was performed for auger holes in the pilot area of the FAL-UnB, with 2D and 3D visualization of soundings with the insertion of information in the objects. A GeoBIM application was performed demonstrating the dynamic connection between Autodesk and ESRI cloud for the modeling of the auger holes. It is noteworthy that the multicriteria analysis applied in the context of aquifer recharge was satisfactory, with the identification of areas of higher and lower suitability. It is emphasized that the adoption of BIM is a process that requires a change in culture, not just software. The integration between technologies for geotechnical in the context of Industry 4.0 requires structured data, which makes initiatives focused on standardization fundamental.
