BLAST & PAINT
Blast & Paint Services
The work measurement process applicable to blast & paint will measure the following elements: Pre-treatment of surfaces, Surface preparation, and 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 duration and costs, and associated detail must be understood as the foundation for the work measurement process.
- Measurement of the physical work on a 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
- Troubleshooting 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
