The capability has been conceived as a MACRO-MODULE composed by three modules, which can either inter-operate or work independently, according to the possible intervention scenarios:

1. Basic Seismic Assessment module (BSA): for ordinary usability assessment.(Resp. DPC)
2. Advanced Seismic Assessment module (ASA): for strategic and/or complex structures, with dedicated instrumentation. (Resp. EUCENTRE)
3. Short-term countermeasures module (STC): to prop up damaged structures and infrastructures. (Resp. VVF)

Such a structure allows ensuring the future possibility of a modular implementation by the Member States, according to their available resources.

Intervention Scenarios

For ordinary buildings, surveys are carried out by BSA teams. In case of need of short-term countermeasures for public safety reasons, the STC team is immediately involved. Then, if possible, the usability is evaluated, otherwise the ASA teams are called.
For strategic/complex structures, surveys are carried out by ASA teams. In case of need of short-term countermeasures for public safety reasons, the STC team is immediately involved. Then, the usability is evaluated, based on numerical and experimental investigation.
When the STC team arrive first, they evaluate the need for short-term countermeasures. Following, BSA or ASA teams are called for the usability evaluation, if needed.
