Well Foundation Inspection
Planys conducted structural audit of the well foundation of a critical highway bridge in West India. ROV Beluga was deployed for this operation consisting of multiple scope of work and completed in 10 days.
Scope of Work: Complete structural audit of a bridge including underwater visual inspection of 11 Well foundations, UPV test for a total 936 points and chemical tests for 14 points of various parts of a bridge including substructure, slabs and joints.
Planys Solution: The inspection was performed using Planys’ ROV Beluga equipped with high resolution camera, turbid water module, altimeter and depth sensor.
- Over 120 anomalies were identified and categorised into minor, moderate & major based on the size of the defects that included cracks, exposed rebars, honeycomb formations, pinholes.
- UPV points taken were categorised as doubtful, medium, good and excellent points as per IS 13311 (Part – 1) – 1992 and chemical tests reported as per IS 2720 (Part 26).
- Planys’ proprietary image enhancement algorithm was used to enhance the videos taken in the extremely turbid waters
- All anomalies/defects were plotted against geo-tagged CAD drawing of every section on the Planys Analytics Dashboard (PAD) with localised click-to-view video.
