Window analysis technique;
As a common practice in Window analysis, delay events are inserted in the impacted schedule and then determined the impact of delay events on project completion for that particular window period. Then progress is being updated , till the end of window period to notice delays , and report the shift in project completion at the end of window span considered.
My questions;
Can the Contractor change relationships , lag , duration ,in the updated programme based on the Site conditions. If it is yes...Let me give another example.
The Contractor has delay for a initial peirod of one year. In the first window of analysis, which is after a year , contractors demonstrates there is no delay in the project completion, by reducing the lag, duration and changing the relationship type. However, as per the approved baseline program the Contractors is culpable of 100 calendar days of delay.
Contractor demonstrates that he has mitigated this delay.
However, in the next window period , Contractor demonstrates delays, at the time period of Employers culpable delay event and then claiming for extension of time. The Contractor also demonstrates that, he was not able to mitigate due Employers delay.
Is this claim logical???
