According to Madhurvani Infra, the construction company in Pondicherry, the term rehabilitation has two connotations, it can be seen as an action in the structure itself, or an action involving the civic restructuring of the region where the structure is located.

Restoration, renovation, maintenance and retrofitting are the main concepts of the Rehabilitation of Buildings.

Restoration is done to save and reveal the aesthetic and historical values of the monument, grounded on respect for the original material and authentic documents. Renovation is the alteration of the conditions of a structure, aiming at recovering, perfecting, or adding its habitability, usability, or safety conditions, with or without a change of function, other than maintenance.

Maintenance is the activities carried out to conserve or recover the functional capacity of the structure and its constituent systems so that they satisfy the requirements and safety of its users.

Retrofitting is about the addition of a structure, an intervention on an estate so that the old one is reformulated into a new one. Retrofitting is the process of altering a structure in retrospection to ameliorate its performance characteristics. The structure is retrofitted keeping in mind its purpose of use, performance conditions, the position of safety, and continuity needed, with due consideration of the ease of conservation, as well as the overall frugality.

Madhurvani Infra, being one of the best building contractors in Pondicherry, the process starts with examination and attestation of the health of the structure. The structure is completely audited using visual checks, non-destructive testing, destructive testing, concrete scanning etc. Structure delineations, former conservation records etc., are also reviewed, if available. Grounded on examination, the performance of the structure is evaluated. However, recuperation or retrofitting may have to be decided depending on provident viability. If the structure is planted to be deficient and doesn’t fulfill performance conditions, it also will be redeveloped. A combination of different ways is generally used depending on the demand and point limitations.
