Steel Bridge Erection Practices

摘要

The erection of steel bridges, depending on the complexity of the structure, may pose critical issues for owners. Given such complexity, plus the great variety of practices being used today, there are often concerns with the integrity, speed, safety, quality, delays, and claims related to steel bridge erection. The number of curved structures and structures with complex geometry that are being constructed adds considerably to the type of steel erection issues that owners, designers, fabricators, erectors, and contractors are faced with at one time or another. A compilation of the methods employed by agencies or firms involved in all phases of a project, from design through construction, may be informative and may minimize these difficulties. This synthesis reports the results of and analyzes questionnaires, telephone conversations, specification reviews, and research reports solicited from states, Canadian provinces, fabricators, and erector and contractors. A total of 111 questionnaires were distributed, with responses received from 30 states, 2 provinces, 15 fabricators, and 4 erector/contractors. The report concentrates on girder bridgesboth I-girders and box girders.
