How is forensic schedule analysis performed for construction litigation?

Forensic schedule analysis reconstructs what happened and determines responsibility for delays. Steps: (1) Establish baseline schedule validity - reasonable logic, durations, critical path, (2) Document as-built dates from contemporaneous records (daily reports, photos, correspondence), (3) Identify delay events with dates and durations from factual evidence, (4) Apply analysis method appropriate to available data (TIA, collapsed as-built, windows), (5) Determine concurrent vs serial delays, (6) Allocate delays to responsible parties, (7) Calculate compensable vs excusable days, (8) Quantify delay damages (extended general conditions, lost productivity). Expert testimony often required; analysis must withstand cross-examination.
