Buildings built in the early 70s & late 80s in India are found to be in a state of disrepair due to inadequate clarity and poor construction procedures. Continuous monitoring of concrete structures using appropriate NDT (Non-Destructive Inspection) methods and the use of possible restoration methods helps significantly reduce the deterioration of concrete structures thereby extending the lifespan of buildings. NDT methods are very useful in assessing consistency, homogeneity, approximate pressure strength, durability, degree of corrosion of metals in concrete etc. of damaged buildings. The purpose of this study is to improve the health of a 50-year-old hospital building (Part of the RC and Brick masonry) in Kurnool, Andhra Pradesh. The condition test was performed by visual, field and laboratory testing of samples collected from the structure and the results are presented in this paper. This paper also highlights the strength and durability of concrete to assess the degree of stress and damage to a building. In addition to visual inspections, Non-Destructive Tests covering the values of USPV & Rebound Hammer and Half Cell Potential in relation to corrosion of reinforced bars and chemical testing in non-compressive RC columns, beams, and slabs are also presented and discussed. Corrective and reinforcing methods using the latest materials and possible restoration activities such as column jackets, shotcreting, anticorrosive coatings, etc. proposed to improve the life of the building..
