So,
This contractor was working under a 6 day-workweek calendar (Stablished in the contract), but in the seventh day (say, the sunday when there were no one working at the place) a storm hit the place of the works and the 8th day the place was not available to be worked because it was flooded. It took that day to recover from the efects of the flooding.
The storm affected activities over the critical path, the question is: The affectation to the finish date is one day (the flooded day) or two days (The day when it was raining plus the flooded day) ?
What do you think?
