Time Impact Analysis (TIA)

In Plain English

A formal schedule analysis that measures how much a specific delay event pushes back the project completion date.

Definition

A Time Impact Analysis (TIA) is a forensic scheduling method used to quantify the impact of a delay event on the project completion date by inserting the delay into the project schedule at the time it occurred and measuring the shift in the critical path. TIA is the preferred method for prospective (forward-looking) delay analysis during construction and is often required by contract to support requests for time extensions.
