Results
- Wire events identified and located by Pure Technologies, and reported to client and consulting engineer.
- Consulting engineer schedules annual investigation of existing recesses and/or creates new recesses to check condition of the strands on which the wire events may have occurred.
- Based upon the condition of the strands inspection, the consultant recommends tendons for replacement.
Through these inspections, 81 wire failures have been confirmed by the finding of tension deficient cables in the reported areas. The monitoring results are displayed in the chart, which shows the linear nature of the post-tensioning deterioration in the three (3) ground level slabs. This consistent rate allows the client to accurately budget tendon replacements to maintain the structural integrity while minimalizing unexpected costs and interruptions to the garage operation.
