Visual inspection is the preliminary and most essential stage of a structural audit. It involves a detailed on-site examination of the building components such as columns, beams, slabs, walls, and foundations to identify signs of distress, deterioration, or structural defects. The inspection focuses on detecting cracks, corrosion of reinforcement, water leakage, efflorescence, spalling of concrete, and any deformation or settlement. The observations recorded during this stage help in assessing the overall health of the structure and determining the need for further non-destructive or laboratory testing. Visual inspection serves as a cost-effective method to evaluate the structural stability and prioritize maintenance or repair actions.
