In terms of construction sequence, I would scale the building industry in the following manner:
1. Architect/Engineer
2. Surveyor
3. Grader
4. Utility Plumber/Electrician- Utility Service
5. Carpenter-forms
6. Iron worker-rebar
7. Mason-foundation
8. Carpenter/Iron Worker-framing
9. Roofers
7. Electricians/Plumbers- building infrastructure /fire protection
8. Glazers/Carpenters- Windows and doors
9. HVAC
10. Insulators-interior and exterior
11. Carpenters-exterior envelope
12. Drywallers/tapers
13. Tub, Tile and floor installers
14. Cabinet and countertop installers
15. Finish Electricians, carpenters, and plumbers- sinks, lights, fixtures, etc.
16. Painters
17. Carpet/wood floor installers
18. Audio, Visual, Communications, and security installers
19. Painter
20. Landscaper
We had a discussion sometime back about the value of the painting product, in terms of its importance in the building industry compared to the other trades mentioned above, and in regards to its contribution to the function and longevity of a structure. Especially, considering that many building materials no longer require a field applied protective coating.
At the end of the day, it was my conclusion that the painting product provides most of its value in terms of aesthetics, rather than utility. After all, a structure doesn't become a business, or a home, until after it has been painted.
So in terms of compensation, it would make sense that the more critical positions in the construction sequence, should merit a higher reward than those that follow.
And until design sensibilities can prove to merit the same importance as running water, flushing toilets, lights, shelter, and warmth, painting will continue to be relegated to the level of "pretty", and therefore, will continue to be rewarded at that level.
