Case Study on Underpinning of Foundation for an Industrial Building Renovation

Abstract

Underpinning involves strengthening of foundation for existing structures using various methods. One of the suitable methods is adapted according to the subsoil and site conditions. One such method is extending the dimensions of existing foundation to rest under supportive soil strata. This method is effective in renovation of existing buildings where more space is available for working condition and requires skilled manpower. This paper deals with a case study on underpinning for an industrial building at Virudhunagar, Tamil Nadu, India. Since there is a need for a conversion of an existing spinning mill to an industrial plant, the necessity for strengthening the existing structures was proposed. The suggested method of underpinning by extending the breadth and depth of existing foundation was carried out and the outcome proved to be successful.
