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.
- In-situ quality assessment, durability investigation and residual life assessment of concrete structures
- NDT, Pile integrity testing and Impact echo testing
- Distress investigations of buildings, bridges, dams, power plants, chimney, silo etc. deteriorated due to aggressive environment or fire damaged structure
