Structural Audit is an overall health and performance medical examination of a building like a doctor examines a patient. It ensures that the building and its premises are safe and don't have any risk. It analyses and suggests acceptable repairs and retrofitting measures needed for the buildings to perform better in its service life. The project is to detect the faults and the problems which are likely to cause threat to the building structure. The visual inspection is done to detect the visual cracks in columns, beams, slabs and walls of any sign of deterioration. The other methods are Destructive and Non-destructive testing method (NDT). In this project we are auditing the structure by Non-destructive testing method, in which it includes Rebound hammer test, Ultra sonic pulse velocity test and Half-cell test; in Ultra sonic test we performed it for columns C1, C2, C3, etc. After examining the defects and faults of the structure, we have to prevent for deterioration with special repairing methods. The method used in our project for repairing are Grouting for filling up the cracks, slab strengthening by micro concrete, jacketing for beams and column, waterproofing of terrace slab and plastering work for walls. Different suitable materials were used for different methods of repairing such as micro concrete which is one type of non-shrinkage material used as concrete in strength of slab and jacketing, cement motar (1:6) for plastering, etc. Therefore the above methods are used and reading of NDT are carried out before and after repair for better understanding of change in strength after repair. Also the estimated material cost for repairing work is calculated.

Non-destructive testing, Grouting, jacketing
