This General Report presents a summary of the eleven (11) papers accepted for the session 8 focused on Case History of Forensic-Geotechnical Engineering and Case Histories on Health Monitoring and Retrofit of Infrastructure. The session includes discussion of Reliability of Codes; Risk Analysis Pertaining to Public Structures, Non-Destructive Evaluation and Load Testing of Drilled Shafts, Auger Cast Piles and Driven Piles, and Damage Evaluation; Advance Information, Systems in the Geotechnical Risk Predication and Assessment. The papers originate from eight countries and cover an array of important topics in the area of forensic and geotechnical engineering. These include case histories; geotechnical-forensic engineering investigation of structures; probabilistic three dimensional modeling; behavior of laterally loaded piles; failure of helical anchors; working pile load tests; refurbished used of timber piles; and vibration effects on historic buildings. A list of the papers is assimilated in Table 1 by topic. The summary illustrated below will give the reader(s) a general overview of the focus of those papers and is intended to direct the reader to their area of interest. The activities of Session 8 also include case histories on health monitoring and retrofit of infrastructure, including bridges, tunnels, and other transportation and geotechnical structures, and their effects on existing facilities and buildings, and remediation. The Session 8 organizers greatly appreciate the efforts of the authors and commend the quality of the accepted papers
