Dimensional Control Surveys (AKA DC or TTS)

ENG-CAD’s Dimensional Control Survey Department has been specifically created to undertake highly accurate Laser Total Station Surveys to electronically capture / verify existing equipment and assets as well as the provision of a precision dimensional control facility throughout the fabrication and commissioning phase of any construction project.

Because of our extensive practical design and construction background, we are able to offer a comprehensive and flexible service removing both the requirements for costly on site fabrication activities and thereby drastically lessoning the business risk for any integrated engineering development project.

Our diverse portfolio already boasts a considerable variety of major clients within the Oil & Gas, Petrochemical, Nuclear, Public Utility, Renewable Energy fields including Marine Engineering and we are continuing to expand our horizons to encompass the entire spectrum of engineering construction enterprise.

Pipe spool Verification pre-post and brownfield surveys are most common and provide invaluable “peace of mind” and a vast cost saving approach to the successful installation of new or replacement pipework by using special software to calculate flange angles and bolt hole rotations.

Typical Applications

  • Flowline installation
  • Brownfield upgrades
  • Derrick alignments
  • Module hook-ups
  • Jacket/topside hook-ups
  • Vessel change-outs
  • FPSO conversions
  • System as-builts
  • New platform build control
  • Clash checking
