More than ever, the construction industry is concerned with improving the social, economic and environmental parameters of sustainability. The purpose of strengthening is to increase the load-carrying capacity or stability of a structure with respect to its previous condition. It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program.

Post Structural Audit 4. This code provides the minimum requirements for the evaluation, repair, rehabilitation, and strengthening of existing concrete buildings and, where applicable, in nonbuilding structures. There is demand of appropriate actions and measures for all such building structures to improve its performance and restore the desired functions of structures which may leads to increase its functional life.
The code is comprised of both prescriptive and performance requirements.

This paper deals with study of different parameter of structural audit including visual inspection, non-destructive testing, core sampling and testing. Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient.
It ensures that the building and its premises are safe and have no risk. A newer version of this document exists.
The former refers to the restoration of acj sectional or monolithic properties of damaged members, while the later refers to the restoration of structural surfaces to a satisfactory operational standard.
