The time impact method of delay analysis, also referred to as TIA, is a technique similar to the impacted as-planned analysis, which forecasts or predicts a delay’s effect on a project’s completion date. This schedule analysis method involves the insertion or addition of activities indicating delays or changes into an updated schedule representing progress up to the point when a delay event occurred to determine the impact of those delay activities.
Implementation of a time impact delay analysis involves identifying project delays or changes, and then inserting or adding activities which represent the delays or changes into an updated schedule representing job progress just prior to the occurrence of a delay or change. The resulting schedule demonstrates the effect of the delays or changes on the project completion date.
It should be noted that there are several important considerations for choosing an appropriate analysis methodology. Each claim is unique and deals with different contract requirements, situational contexts, levels of documentation, complexities, legal jurisdictions, and dispute resolution forums, among other factors. The selection of a particular analysis method should be based on professional judgment and diligent factual research and evaluation.
