APPLY has a prefab dimensional control team that verifies prefabricated elements and installations, especially for facilities where extreme accuracy is required due to hazardous environment or limited time for assembly on site (e.g. offshore facilities).

Prefab dimensional control should be executed at all stages of manufacturing:

  • Production
  • Final acceptance
  • Dispatch

The scope of our services includes (but is not limited to):

  • Stake outs on site and during prefabrication
  • Fitting checking and as-built measurement
  • CAD-based 3D inspection
  • Reverse engineering
  • Plane defining and flatness check


  • Limitation of on-site activities by maximizing off-site activities (reduction of construction schedule and cost)
  • Elimination of re-work (maximizing work efficiency)
  • Reduction of assembly time (minimizing offshore welding and fitting)
  • Minimizing shutdown durations (earlier project completion)
  • No surprises (risk mitigation)


  • Pipe spools
  • Valves
  • Fabricated assemblies
  • Packaged equipment such as pump skids
  • Christmas trees and associated equipment
  • Tunnels, roads, bridges
  • Stadiums, buildings
