Visual Inspection & Documentation

• Cracking, spalling, delamination, corrosion stains, settlement

• Identification of structural distress symptoms

• Drone or rope-access surveys for hard-to-reach areas

Non-Destructive Testing (NDT)

• Rebound Hammer Test – estimates surface hardness

• Ultrasonic Pulse Velocity (UPV) – assesses internal flaws

• Ground Penetrating Radar (GPR) – detects rebar position, voids

• Half-cell Potential Testing – evaluates rebar corrosion activity

• Infrared Thermography – reveals subsurface anomalies

Material Sampling & Laboratory Testing

• Core sampling and compressive strength tests

• Chloride content analysis

• Carbonation depth test

• Petrographic analysis (microscopic examination of concrete composition)

• Sulfate attack or alkali-silica reaction (ASR) tests

Structural Assessment

• Evaluation of load-carrying capacity

• Finite Element Modelling (FEM) and structural simulations

• Code compliance review (e.g., ACI, Eurocode, BS)

Cause & Origin Determination

• Investigation of failure origins: design flaws, material defects, workmanship, environmental exposure, etc.

• Assessment after fire, seismic events, overloading, settlement, or explosions

Repair and Rehabilitation Recommendations

• Customized repair strategies

• Materials and method selection (e.g., FRP wrapping, epoxy injection, cathodic protection)

• Monitoring plans

Expert Witness & Legal Support (if applicable)

• Technical documentation and reporting

• Support in litigation or insurance claims

• Testimony in court, if necessary
