| Résumé : |
Designed to assist the coatings engineer or specifier in identifying candidate protective coating systems for specific service environmnents applicable to a broad array of industries, this guide provides the following.
- Commonly used generic coating systems
- Service life for each in specific environments
- Current material costs
- Current field and shop painting costs
- Guidelines for calculating approximate installed costs of the systems.
Guidelines for developing long-term life-cycle costs and number of paintings for the expected life of the structure are also included. The basic elements of economic analysis and justificatgion are addressed together with guidance on the preparation of a present value analysis. Examples are provided to aid the reader in the proper use of the information. |

- Table 1 : Examples using practical maintenance sequence : system with 20-year practical life and original shop-installed cost of $4.10 per square foot, and with 20-year practica llife and original field-installed cost of $5.11 per square foot
- Table 2 : Examples of present values analysis : total painting cost per suare foot 45-year plant life, field application three-coat epoxy zinc/epoxy/polyurethane, blast-cleaning, 14-year system life (severe/C5-l)
- Table 3 : Example of economic analysis : total painting cost per square foot for 35-year structure life, moderate (C3) environment one-coat inorganic zinc system, shop-automated blast-cleaning 17-year "P" life, inflation = 4%, interest = 7%
- Table 4A : Estimated service life for practical maintenance coating systems for atmospheric exposure (in years before first maintenance painting)
- Table 4B : Estimated service life for practical maintnenace coating systems for immersion service (in years before first maintenance painting)
- Table 5 : Typical material costs of paints and protective coatings approximate cost per square foot at typical DFT
- Table 6 : Shop painting costs per square foot including labor, equipment and related costs (no material costs included) - Size of job multipliers (per square foot) - Member size multipliers for hot dip galvanizing member weight per foot (Lbs./Ft)
- Table 7 : Field painting costs per square foot including labor, equipment and related costs (no material costs included)
- Table 8 : Paint removal containment multipliers guidelines containment designation is in accordance with SSPC technology guide N° 6, guide for containing surface preparation debris generated during paint removal operations
- Table 9 : Detemination of maintenance risk for alkyd coatings |
