Structural Investigation

Standard engineering practice often assumes deterioration requires replacement. TRSC investigations quantify remaining capacity through material testing, load path analysis, and structural modeling. This approach has documented cost savings ranging from $1.7M to $6M per project by avoiding unnecessary replacement.

Investigation Methodology:

• Visual condition surveys documenting defect type, location, and severity
• Material sampling for NATA-certified laboratory testing (compressive strength, tensile properties, chemical composition)
• Non-destructive testing including Ground Penetrating Radar, Ferroscan electromagnetic scanning, and ultrasonic pulse velocity
• Chloride ingress profiling and carbonation depth measurement for durability assessment
• Risk-based condition assessment per AS/NZS ISO 31000:2018
• Structural analysis accounting for as-built configuration and deterioration

12 Creek Street Case Study: Investigation of 42-year-old commercial building external walls revealed chloride concentrations at 0.008-0.036% (well below 0.06% corrosion threshold) and only 2-3mm carbonation depth. Testing proved remediation unnecessary despite visible deterioration.

TRSC operates exclusively in existing asset assessment and does not service new construction markets. This eliminates conflict of interest when providing investigation data to incumbent structural engineers designing remediation solutions. Our investigations deliver as-built documentation and material properties that enable informed design decisions rather than conservative assumptions.

Whether evaluating deterioration mechanisms, planning renovations, or certifying capacity for continued operation, TRSC investigations provide the foundation for evidence-based decision-making.
