Blasting & Coating
The work measurement process applicable to blasting & coating will measure the following elements:
- Pre-treatment of surfaces.
- Surface preparation.
- Application of coating as per paint specification.
The units of measurement applicable to blasting & coating will be as follows:
- Pre-treatment of surfaces – m2.
- Surface preparation – m2.
- Application of coating – m2 for each coat applied.
The work measurement methodology applicable to blasting & coating 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. 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.
- The performance data must reflect acceptable DFTs as stipulated by the client.
- Trouble-shooting issues.
- Resource forecast especially labour.
- Final QA documents.
6Sigma will track and report performance to the client as per our benchmarks indicative for blasting & coating:
- Hull blasting flat steel per hour per nozzle.
- UHP blasting (water jet) flat steel per hour per nozzle.
- Spraying weather dependent.
- Blasting measurement area mapped & labelled.
- Tank measurement & cleaning area mapped & labelled per hour.
