Project Requirements

  • Client needed to drill two core holes through the ferry berth finger arm concrete slab 
  • Aim was to core through the concrete without hitting reinforcing steel
  • Slab was especially thick – beyond the range of our PS1000 scanner (which, at the time, was our lowest frequency antenna), and so any reinforcement near the base of the slab would not be visible when scanning from one face

Solutions

  • CSI carried out image scans from both the top face and soffit of the slab
    • Scanning from the soffit (accessed via dingy) required accurate set-out and was restricted to small areas between the wooden beams supporting the slab
  • Scans were recorded and analysed off site
  • By factoring in the set-out, i.e. the position of the top face / soffit scans relative to one another, analysts were able to superimpose the scan images and determine suitable drill locations

Benefits of Solutions

  • Non-destructive – no damage to the concrete in determining the steel layout. This is especially important as this is a marine area
