(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
Hi Mohamed
If you are talking about overlapping delays the usual rule is that you will be awarded an EOT but no prolongation costs.
But the contract that you signed may not allow this.
Best regards Mike T.
