The work measurement process applicable to fabrication will measure the following elements:
- Material purchase, identification, delivery, preparation and machining.
- Component assembly.
- 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.
