The description of the repairs (the shape, the building materials, the presence of tie bars and so on) is submitted to the expert opinion of architects and engineers.

The goal is to distinguish the structural disorders/repairs –coeval to earthquake occurrence– actually caused by the ground shaking from those related to other circumstances.

The timeline of all building phases determined by the archaeological analysis is a valuable information to elaborate the digital mechanical models of the buildings along the centuries allowing to take into account the past geometries and the evolution of construction materials.
