The National Institute of Occupational Health (NIOH) in India is conducting a structural audit on a residential RCC building in Raigad, India. The building, constructed about a decade ago, is visually distressed due to aging and various factors such as natural calamities, faulty construction, and aging of the structure. The audit was conducted using visual inspection and non-destructive tests (NDT), including rebound hammer tests, ultra-sonic pulse velocity tests, corrosion tests, carbonation tests, and rebar locator tests. The structural audit revealed that the structures were affected by distress, with cracks and damage not being assessed. This led to corrosion in the reinforcement of the structures, which was found to be 30% distressed. The audit recommended retrofitting, and based on the report NIOH, proposed additions and alterations to the existing structures. The building's structural stability was assessed and potential additions and alterations were proposed. Comparitive analysis on Etab between rising two floors in RCC building structure with the help of retrofitting techniques specifically for column and foundation.
