Designing Steel for Ease of Construction

This paper has been illustrated by four case histories of steel bridges. In two cases the designer considered the erection scheme in detail. In both cases the contractor improved on the designer's scheme and completed ahead of schedule. In one case the designer considered erection in principle but not in detail. This may well have been appropriate, but the contractor would have benefited from a definition of what the designer did and did not consider. In the other case the designer apparently did not consider erection at all when preparing the design and the question is left open as to how the economy of the bridge would have been affected if erection had been considered.
