This report presents a proposed UNIFORMAT II classification of bridge elements. Elemental classifications differ from traditional product-related classifications because their core concept is an element that performs a given function, regardless of the design specification, construction method, or materials used. The proposed classification represents a major revision and restructuring of ASTM Standard Classification E 2103, a bridge-related standard classification first issued by ASTM in 2000. The original bridge classification, E 2103, differed from the UNIFORMAT II elemental classification hierarchy in several ways which limited its applicability. The major revisions to E 2103 described in this report will promote its relevance, understanding, and acceptance in the bridge industry. Once approved and reissued by ASTM, the UNIFORMAT II Standard Classification of Bridge Elements, E 2103, will provide the basis for a comprehensive data set of bridge-related costs that will enable public and private decision makers to choose more cost-effective solutions for the design and construction of new bridges and the maintenance and repair of existing bridges across the Nation.
