COSTING CONSIDERATIONS FOR MAINTENANCE AND NEW CONSTRUCTION COATING WORK

摘要

This paper updates "Updated Protective Coating Costs, Products, and Service Life"(l) on protective coating costing and selection co-authored by G. H. Brevoort, M. F. MeLampy and K. R. Shields. Beginning with this edition, data collection and publication will be co-authored by K. R. Shields, M. F. MeLampy and M. P. Reina.rnDesigned to assist the coatings engineer or specifier in identifying suitable protective coating systems for specific industrial environments, this paper provides guidelines for calculating approximate installed costs, expected coating life for each identified system, and how to determine the most cost-effective systems. The effect of maintenance sequences on long-term costs and system performance is also reviewed.rnNew features of this paper include life-cycle and material costs for hot dip galvanizing.rnIncluded in the paper are 1) most commonly used generic systems in typical industrial environments, 2) service life for each, 3) current material costs, and 4) current field and shop painting costs. Guidelines for developing long-term life-cycle costs, and number of paintings for the expected life of the structure are included. The basic elements of economic analysis and justification, and how to prepare a Present Value Analysis are also addressed. Worksheets and examples are provided to aid the reader in the proper use of the information.
