Structural Audit Services

A structural audit entails evaluating the overall health and performance while ensuring that the building and its premises are safe and are at no risk. A structural audit is done by an experienced and licensed structural consultant who analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life.

 

TCR Engineering has undertaken various structural audit services for both residential and commercial buildings including Vikas Complex in Thane West, KC College in Thane and Essential Power Transmission in Andheri, Mumbai. As per clause No.77 of revised Bye-Laws of Cooperative Housing Societies: The Society shall cause the ‘Structural Audit’ of the building as follows: 

​

  1. For building aging between 15 to 30 years once in 5 years 

  2. For building aging above 30 years once in 3 years 

Purpose of Structural Audit

  • To save human life and buildings and warn against any potential threats or failures

  • To understand the condition and health of a building and to project the expected future life

  • To find critical areas that need to be attended or repaired with immediate effect

  • To comply with statutory requirements of municipal authorities

  • To proactively assist the residents and the society to understand the seriousness of the problems and the urgency required to attend to the same

  • To enhance the life cycle of a building by suggesting preventive and corrective measures like repairs and retrofitting
