Reasons for Strengthening the Old Supermaket

The existing supermarket building exhibits advanced structural aging and concrete degradation, with critical signs of distress:

Through-cracks observed on the soffit of reinforced concrete slabs, indicating loss of flexural stiffness and potential for crack propagation under service loads.

Degradation of concrete cover on beams and columns, leading to reduced cross-sectional capacity and increased risk of reinforcement corrosion.

Inadequate load-bearing reserve to accommodate updated operational loads (e.g., higher racking loads, MEP equipment upgrades) as per current commercial building standards.

Core Objectives

• Damage Mitigation & Durability Enhancement. Arrest crack propagation in slabs and beams; restore structural integrity and prevent further concrete degradation.

• Load-Carrying Capacity Upgrade. Increase the flexural and shear capacity of slabs, beams, and columns to meet revised design loads and ensure compliance with relevant building codes.

• Safety & Resilience Improvement. Enhance the overall structural ductility and seismic resilience, aligning with modern safety standards for commercial occupancy.
