There is a growing societal demand for geohazard risk assessment information, for which reason research institutions are nowadays requested to develop increasingly more advanced and comprehensive risk services. Within the European Research Infrastructure EPOS, risk services are already being provided in two of its Thematic Core Services (TCS): Seismology and Tsunami. To further develop such services, whilst avoiding duplication of efforts, as well as to potentially add them to other hazards covered in EPOS (e.g. volcanoes and anthropogenic hazards), it is proposed that a new TCS focused on the provision according to FAIR principles of data, data products, services, and software (DDSS) related to buildings and urban infrastructure, i.e. the built environment, is created.

A TCS on Built Environment Data would involve leading engineering research groups from across Europe that would work together in the provision of services regarding, e.g.:

• hazard-agnostic exposure databases (buildings, infrastructure and population);
• dynamic models of exposure evolution;
• access to structural testing facilities;
• access to experimental data.

In addition to the engineering research community, it is expected that this TCS would also see the involvement of other disciplines, such as social sciences, urban planning, climate adaptation etc., so that data on social, economic and environmental aspects can also be integrated in the developed services.
