Comprehensive fire damage assessment of bridge girders, evaluating structural integrity through pulse velocity testing and petrographic analysis. Findings identified critical areas of deterioration, guiding targeted repairs and long-term rehabilitation strategies for restoring concrete durability.

Case study analyzing extensive concrete spalling and rebar corrosion at the Hall of Records building. Findings indicate corrosive soil, high chlorides & sulfates, and carbonation as primary causes of deterioration. Evaluation involved NDT, core testing, and chemical analysis. Conceptual repair options and recommendations are discussed, including the use of FRP to strengthen cracked columns.
