Economic cost
TOTAL COST 1,6 M€
Most of the costs incurred in phases 1 and 2 can not be recovered from the insurance company.
The insurance company, in phase 3, only accept the reconstruction costs, no improvements.
Build safer facilities often need a more complex legal process that simple reconstruction.
