Fabrication

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

  • Material purchase, identification, delivery, preparation and machining.
  • Component assembly.
  • Welding.
  • Cleaning & coating.

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

  • Material purchase including the date of order.
  • Material delivery including the actual order delivery date.
  • Material identification stipulating who identified the material, when it was identified & whether or not class approval/verification is required.
  • Material preparation requires a status report from workshop showing the process to be followed and the durations of each sub-activity.
  • Material machining as above for material preparation.
  • Welding includes a status report from the workshop and the total length of welding required.
  • Coating includes a status report from workshop reflecting completed m2.
  • Daily progress summaries per work element from workshop.

The work measurement methodology applicable to fabrication 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, where fabrication work is executed on-site, 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 fabrication workshop around 13h00. Measurements will be logged on a spreadsheet dedicated to fabrication and properly referenced to the work area and/or grid plan and/or schedule reference. Adjustments will be made for work measured but 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.
