Journal of Environmental Management publishes new article:  Comparative Life-Cycle Cost Assessment of Painted and Hot-Dip Galvanized Bridges

The article, written by Professor Barbara Rossi, focuses on the maintenance and life-cycle cost assessment of painted vs. hot-dip galvanized steel bridges in a class C4 environment of patch-up, overcoatings and removal/replacement. It was concluded the initial cost of the painted option may be less expensive than the HDG option, but after 18.5-24.2 years once the painted bridge is overcoated, the HDG bridge is more economical.

The article includes a sensitivity analysis of the NPV, the escalation and discount rates and their effect on the life-cycle cost; as well as the influence of a maintenance scenario. Read the full article at : and see the related video at
