Piping

The work measurement process applicable to piping will measure the following elements:

  • Removal of existing pipe.
  • Fit-up of new pipe.
  • Installation of:
    • Elbows & bends
    • Sleeves & collars
  • Valves & flanges.
  • Completion of all welding.
  • Pressure testing as to pass or fail.
  • Commissioning of system as to operative or not.

The units of measurement applicable to piping will be as follows:

  • Removal & fit-up of existing pipe – linear metres.
  • Elbows, bends, sleeves, collars, valves and flanges – % fitted or not fitted.
  • Pressure testing – conforming with planned dates for completion.
  • Commissioning – complete or not complete.

The work measurement methodology applicable to piping comprises the following steps:

  • The final contract quantities, specifically including durations and costs, and associated detail must be understood as the foundation for the work measurement process.
  • Measurement of the physical work on project will take place twice daily – around 08h00 to determine night shift production and around 18h00 to determine day shift production. Adjustments will be made for work measured but which is then not accepted by QC.
  • A daily visit will be made to the piping workshop around 13h00. Measurements will be logged on a spreadsheet dedicated to piping and properly referenced to the work area and/or grid plan and/or schedule reference. Adjustments will be made for work measured but which is then not accepted by QC.
  • All measurements must be reconciled against project schedule at timenow and Variation Order Register and also reflect the following:
    • Rate of production.
    • Troubleshooting issues.
    • Resource forecast especially labour.
    • Final QA documents.

6Sigma will track and report performance to the client as per our benchmarks indicative for piping.
