AACE RP 29R-03
AACE International's Recommended Practice 29R-03, "Forensic Schedule Analysis," classifies delay-analysis methods by a structured set of practical questions -- timing, data availability, and whether the goal is modeling or observation -- rather than prescribing one preferred technique.
Definition
Published by AACE International (originally the Association for the Advancement of Cost Engineering), RP 29R-03 organizes the forensic scheduling field around a decision framework: is the analysis contemporaneous or retrospective, is a reliable schedule update available to work from, and is the goal to model a hypothetical scenario or observe what actually happened. Working through those questions in order is meant to lead to a defensible method choice for a specific dispute's facts, rather than picking a technique out of habit. It covers much of the same ground as the SCL Delay and Disruption Protocol, organized differently.
Example
Applying RP 29R-03's framework to a dispute with a good contemporaneous schedule update available points toward Time Impact Analysis, while the same dispute with only a baseline and a final as-built record points toward Windows or Collapsed As-Built analysis instead.
