In the summer of 2007, the Association for the Advancement of Cost Engineering International (AACE International) published its Recommended Practice No. 29R-03 on Forensic Schedule Analysis (RP/FSA). The RP/FSA provides a framework or structure that identifies, classifies, and explains the implementation of various schedule analysis techniques from a forensic or after-the-fact perspective. The goal of this paper is to build upon the foundation established in the RP/FSA by synthesizing the contemporaneous period analysis (CPA) or contemporaneous schedule analysis, which falls under the observational/dynamic/contemporaneous split (MIP 3.4) classification, and the most appropriate of the time impact analysis (TIA) family of techniques, which falls under the modeled/additive/multiple base (MIP 3.7), into a single and coherent schedule delay analysis system for analyzing schedules and determining delays on a construction project. This objective was accomplished by first evaluating each MIP identified in the RP/FSA from the perspective of its appropriateness for inclusion in a comprehensive, project-based system for analyzing schedules and measuring delays throughout the life of a project. Once the appropriate components have been identified, the next step will be to describe how the pieces work together as a single system, and to lay out some basic rules for implementation.
