Tips on using this forum..

(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.

Can anyone help  understand the difference in between Time Impact Analysis and Window Analysis for the purpose of Extension of Time and delay analysis.

I have refered to few methods but I feel both were same.  I would appreciate any help in understanding the delay analysis techniques also if i can get the procedure to calculate both.


Thanks and regards,

Vineet Singh

A TIA is a forward looking prospective schedule analysis technique that adds a modeled delay to an accepted contract schedule to determine the possible impact of a delay to the project completion.

A Window Analysis is a backward looking or forensic way to look at a delay within a specific "WINDOW" of time. 

The window analysis is mroe time consuming, more expensive to prepare, require more expertise, more research and preperation time to complete
