(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.
Under all of the delay analysis protocols each delay event needs to be analysed separately. If the event caused a delay to completion an EOT is warranted. In the scenario described, any later claim has to allow for any previously approved (or claimed) EOT.
This situation is a good example of a scenario where ‘time windows’ are a useful approach. The actual situation at the start of each time window is the baseline, and delay at the end of the window attributable to a claimable event is the EOT claim.
