Pipelines & tunnels

  • Oil & gas pipes — 3D (xyz) location & relocation of oil pipelines buried & underwater
  • Sewerage tunnels — 3D location & condition sewer tunnels & diffusers
  • Water tunnels — 3D pathways, location & condition of water tunnels
  • Railroad tunnels — Measure the elevations of railroad tunnels underwater
  • Electric cables — Map 138 & 345 kV cables & communications cables buried & underwater
  • Internal evaluation — Measure geometry, fluid content & integrity of pipelines & sewer tunnels.
  • Preconstruction pathway surveys — Map the properties of gas & oil pipelines
  • Acceptance survey — As-built pipeline & cable relocations
  • Safety survey — Before & during construction
