ABSTRACT
In the last decades, Lisbon Municipality has implemented a database – GeoSIG to collect, analyse and produce specific outputs suitable for planning and management, using geological and geotechnical data obtained through several work field campaigns. This information allows the identification of the main constraints to occupation, such as a high thickness of coverage deposits or low depth of the water level. In addition, the same information can be used as an input to promote sustainability actions, such as better underground water management or a more responsible underground occupation. Besides the geological and geotechnical setting, Lisbon has also been doing a 3D underground structures and infrastructures representation, considering the impact that these objects can have on natural resources, specific the water flow. To achieve this, the geological and underground information was joined to promote the development and implementation of policies regarding the underground occupation, considering the impact mitigation and the possibility of exploring underground resources, allowing better decision-making.
