What a time impact analysis shows

A time impact analysis inserts a fragnet for the delay event into the schedule update in force just before the event, and measures the change to the completion date. AACE International Recommended Practice 52R-06 describes the method, and many federal and transit specifications require it for time extension requests.

How we prepare a TIA

• Choose the right schedule update: the last accepted update before the event
• Build the fragnet: the new or changed activities, durations and logic, with the source of each
• Run the analysis and compare completion dates and float before and after
• Check concurrency: contractor delays in the same window
• Write the narrative: what happened, when, why it is excusable, and the time requested
• Package the request with the native schedule files the owner needs to reproduce it

Common reasons TIAs are rejected

• The fragnet is inserted into the wrong update, or the update itself was never accepted
• Durations in the fragnet are not supported by records or the change scope
• The analysis ignores contractor delay in the same period
• Notice was late under the contract’s changes or delay clauses
• The owner cannot reproduce the result from the files provided

When the TIA is not enough

If time is refused or the costs are large, the TIA becomes part of an REA or claim. See REA and delay claim consultants and, if the schedule needs fixing first, CPM scheduling services.
