摘要：	BridgeLCC is user-friendly, Windows (trademark) software specifically designed to help these engineers with these comparisons. The engineer compiles the costs of building, maintaining, and then disposing of each of the bridges. These costs project costs incurred by the agency responsible for the structure (agency costs), costs incurred by drivers on the highway that are inconvenienced by bridge construction and other bridge activity (user costs), and user costs incurred by third parties who are not direct users of the structure but are impacted by bridge activity (third-party costs). Each of these types of costs are compiled over the life or 'life cycle' of each structure. BridgeLCC uses a life-cycle costing methodology based on the ASTM practice for measuring the life-cycle costs of buildings and building systems (ASTM E 917) and a cost classification scheme developed by NIST. The practice insures that the cost calculations follow accepted practice; the scheme helps the engineer account for all project costs and to properly categorized them.
