This study presents a comprehensive evaluation of reinforced cement concrete (RCC) members situated at the +10.80 m level of an international cricket stadium in Gwalior, Madhya Pradesh, utilizing a series of nondestructive Tests (NDT) and Partial Destructive Tests (PDT). The investigation was undertaken to assess the in-situ material quality and structural integrity of slabs and beams using Ultrasonic Pulse Velocity (UPV), Rebound Hammer, and Core Compression and Chemical Analysis. The UPV results indicated a significant portion of the slab concrete quality falls within the "doubtful" category, while beams ranged from "medium" to "good" quality. Rebound hammer readings generally revealed surface hardness, which is indicative of a lower compressive strength than the design grade (M30). Core compression tests showed variable strength values, with most cores confirming design-grade strength, although the chloride content in several samples exceeded permissible limits, indicating a potential risk of corrosion-induced deterioration. No carbonation effects were observed, and the sulfate content was within the acceptable bounds. This integrated approach highlights the need for localized rehabilitation and continuous monitoring to maintain structural reliability in large public infrastructure.
