Following a protocol with École Polytechnique del' Université de Nantes,, two funded internships will support a research project addressing challenges identified by the Lisbon City Council and its Department of Education in the management of municipal school facilities, particularly related to fragmented data and reactive maintenance practices.  Integrated into ongoing ISTAR-Iscte research on the sustainable management of the built environment, this project will assess the long-term impact of outdoor rehabilitation works in selected primary schools, using Digital Twin and GEO-BIM technologies.
