Abstract: Significant debate surrounds the appropriate means of evaluating concepts such as criticality and concurrency both of which play a central role in many if not most delay or impact claims.Project schedule updates are intended to serve as valuable analytical tools to identify and evaluate criticality and concurrency.However, in certain circumstances, the utility of schedule updates can be compromised by schedule revisions unrelated to the progress of the work including but not limited to resequencing or other means of recovering lost time.Such revisions, although often appropriate and necessary, can conceal the very real effects of project impacts and delay events and further complicate the evaluation of concepts such as criticality, concurrency, and perhaps most importantly the allocation of costs associated with resequencing and acceleration.To overcome this difficulty, stakeholders have increasingly turned to forensic methodologies such as half-step analysis.This paper will overview the half-step methodology, common circumstances where its use should be considered, how owners and contractors can benefit from its use, and legal issues related to its application.
