Structural Assessment & Rehabilitation

Structural Assessment and Rehabilitation programme conducts in-situ quality assessment, durability investigation and residual life assessment of concrete structures such as buildings, bridges, dams, power plants, chimney, silo etc. The investigations are carried out using visual observation, nondestructive evaluation technique (NDE) and other field test followed by laboratory test on extracted core samples and chemical analysis of hardened concrete. The investigation are generally followed by recommendations for repair and rehabilitation with state-of-the-art repair materials and implementation techniques for distressed RC structures covering specifications, cost estimates and bill of quantities.
