In November, SGS TEC SERVICES was hired to gage the structural damage of a devastating fire at Savannah’s Eastern Wharf Waterfront. Our field assessment revealed surface damage such as spalled concrete, exposed reinforcing bars, and damaged PT cables. To further investigate we utilized several testing methods, in particular:
- GROUND PENETRATING RADAR (GPR) non-destructive testing used to identify both steel reinforcement and PT cables prior to coring.
- ASTM C42/C42M “Obtaining and Testing Drilled Cores and Sawed Beams of Concrete”.
- ASTM C856/C856M “Standard Practice for Petrographic Examination of Hardened Concrete”.
- ASTM D4580/D4580M “Standard Practice for Measuring Delaminations in Concrete Bridge Decks by Sounding.”
Following the initial field assessment, we provided a comprehensive report to pinpoint depth of damage, condition of paste and aggregate, and recommendations for the depth of damaged material removal.
