PURPOSE
This recommended practice (RP) for prospective time impact analysis (TIA) is intended to provide a guideline, not
to establish a standard. This recommended practice of AACE International on TIA, as applied in construction
industry projects and programs, provides guidelines for the project team to assess and quantify the effects of an
unplanned event or events on current project completion. While TIAs are usually performed by a project scheduler
and can be applied on a variety of project types, the practice is generally used as part of the total cost
management (TCM) change management and forecasting processes.
