Chris,

Impact-as-planned and Time impact are not very different.

 

Delay Analysis in Construction Contracts

By P. John Keane, Anthony F. Caletka

"The main difference between the TIA & IAP methods is the use of 'multiple base' programmes in the TIA, as opposed to a 'single base' (i.e. the baseline) in the IAP.

Dear Mr. Tastro

I am sorry for revealing the dead topic; I posted the thread coz I really didn’t find my answer. I was confused as I saw a clip on http://www.youtube.com/watch?v=RRhbzfY2aRw  which says that the Time Impact Analysis is a forecast impact of an expected  event. I think I got my answer that it’s the difference btwn the US and the UK terminologies, if I understood you right.

Thanx - Cheers

Hi Tanveer

The definition of Delay Analysis terms depends on if you are British or American.

Time Impact Analysis and Impacted as Planned are interchangeable between the two jurisdictions.

I tried a while back to get common terms established but our US friends were entrenched.

Now - whenever I use a term in a report I classify it as "SCL Protocol Defined" in a footnote so as to avoid any confusion.

Best regards

Hi Hall

Perhaps you didn't realise but you have just responded to a 7 year old thread.

It is not a good idea to liven up long dead topics.

Best regards

Time impact analysis or 'impacted as-planned' analysis is one of several delay analysis techniques. The impacted as planned method consists of listing all the excusable delays (or delays where time extension is owed to the contractor) and adding this extended duration to the relevant activities to determine the revised completion date. The difference between the revised completion date and the as-planned completion date determines the number of days owed to the contractor.
