16.1 All events that take place during the course of the performance of this AGREEMENT, of an unforeseeable nature and that provenly interfered with the progress of the works, shall be typified as Acts of God or force majeure and shall be cause for

characterizes the unforeseeability of the event. Failure to deliver such a notice within the stipulated time limit shall serve as evidence that the event did not affect the progress of the works and that it cannot be, therefore, typified as an
unforeseeable fact for the purposes of exempting CONTRACTORS from responsibility.

losses caused to PRINCIPAL, in addition to being subject to the penalties stipulated herein.
