The document describes a pilot project to create an underground infrastructure register for the cities of Milano, Rho, Pero and Arese in Italy. The project involved mapping underground infrastructure like water, electricity and telecommunications networks using techniques like historical database research and ground-penetrating radar. The data was then combined and made accessible through 2D and 3D online maps. The goal was to test technologies and processes for establishing a national underground infrastructure register to help with planning, maintenance and coordination of underground networks.

2. UNDERGROUND INFRASTRUCTURE REGISTER
The register as an instrument of
knowledge:
• Supporting decision makers in both
design and investment choices to optimize
the use of resources
• Making more effective interventions in
case of failure, and to ensure greater
security of networks and systems
• Making it easier to design renovations of
a network or its expansion
• Identifying existing usable infrastructure
in order to reuse them
•Facilitating access to information on
networks layout in order to avoid
interference construction
