CPM Schedule Validation in Forensic Delay Analysis

Abstract: Critical Path Method (CPM) schedules are routinely relied upon in construction disputes to evaluate alleged delays. However, schedules that have not been validated for structural integrity, logic, traceability, and credibility may yield unreliable critical paths and distorted float calculations. Federal agencies and industry organizations—including the Government Accountability Office (GAO), Defense Contract Management Agency (DCMA), National Aeronautics and Space Administration (NASA), Naval Air Systems Command (NAVAIR), and the National Defense Industrial Association (NDIA)—have published guidance addressing schedule quality and reliability. While these documents were developed primarily for program management and compliance purposes, they collectively establish principles directly applicable to forensic delay analysis.

This presentation will compare and contrast these protocols from a forensic perspective and synthesizes them into a unified, tiered schedule validation framework suitable for expert analysis and reporting. The proposed framework establishes schedule validation as a necessary predicate to the selection and application of forensic delay methodologies.
