Structural Audit Step-by-Step Methodology

Our audit team begins by reviewing the building's historical records, approved architectural drawings, structural layouts, soil investigation reports, and previous repair documentation. We conduct a preliminary site walk-through with housing society committee members to understand occupant concerns, leakage histories, and noticeable structural vibrations.

Every structural member is meticulously inspected and logged:

• Columns & Shear Walls: Inspected for vertical load cracks, settlement cracks, buckling, concrete cover spalling, and rebar corrosion.
• Beams & Slabs: Checked for mid-span flexural cracking, shear cracking near supports, excessive deflection, and underside ceiling dampness.
• Cantilevers & Balconies: Detailed inspection of high-risk cantilever slabs, chajjas, and parapet walls.
• Overhead Water Tanks (OHWT): Examining base slabs, staging columns, and perimeter walls for water leakage, efflorescence, and chemical degradation.

Field engineers deploy calibrated non-destructive testing equipment to evaluate internal concrete strength, crack depths, void locations, and corrosion rates without altering the structural stability of the building.

Collected data is analyzed using STAAD.Pro software. The final report assigns clear categorization:

• Category C1: Building in dangerous condition, requiring immediate evacuation and major structural intervention.
• Category C2-A: Evacuation required for specified structural areas while extensive structural repairs are executed.
• Category C2-B: Structural repairs can be performed without evacuating residents.
• Category C3: Minor non-structural maintenance and cosmetic repairs required.
