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.
