Set up a structural movement and crack-monitoring program for elevated parking structure slabs identified with active distress

Steps

1. Have the structural engineer identify specific cracks, joints, or areas of concern flagged in the condition assessment report as needing ongoing monitoring rather than immediate repair.
2. Install crack monitors (e.g., simple tell-tale gauges or more advanced strain/displacement sensors) at the flagged locations, with the engineer specifying monitoring frequency based on the severity and rate of change observed.
3. Establish a baseline measurement and a documented re-measurement schedule (e.g., monthly, seasonally) with photographs and dimensional readings logged consistently over time.
4. Set defined threshold criteria with the engineer of record for when a rate of change or absolute movement triggers escalation to immediate repair or emergency shoring, rather than leaving 'concerning movement' undefined.
5. Feed monitoring data back into the structure's next required condition assessment report so the responsible professional engineer can factor it into the recommendation on timing for the next assessment, as contemplated under rules like 19 NYCRR 1203.3(j)(7)(ix) (which directs the responsible PE to consider the garage's structural condition, maintenance history, and other relevant factors in recommending the next assessment interval).
