- 4. What is Structural Audit ? Structural Audit is an overall health and performance checkup of a building by an experienced and licensed structural consultant to ensure that the building and its premises are safe and have no risk. It analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life. Objectives of Structural Audit •To save human life and buildings •To understand the condition of building •To find critical areas to repair immediately •To comply with statutory requirements •To enhance life cycle of building by suggesting preventive and corrective measures like repairs and retrofitting
- 5. Types of Audit •Statutory audit •Structural audit •Safety audit •Budgetary audit
- 6. Need of Structural Audit of Building 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: • For building aging between 15 to 30 years once in 5 years • For building aging above 30 years Once in 3 years
- 9. Stages in Carrying Out Structural Audit 1. Study of architectural and structural drawings, design criteria, design calculations, structural stability certificate of existing structures 2. If architectural and structural drawings are not available, as built drawings can be prepared by an engineer 3. Visual Inspection
- 10. Need of visual inspection • to recognize the types of structural defects • to identify any signs of material deterioration • to identify any signs of structural distress and deformation • to identify any alteration and addition in the structure, misuse which may result in overloading
- 11. Scope of visual inspection • General information of the building • Structural System of the building • Addition or Alteration in the building • Dampness and Leakages
