Evaluation Alternatives
Choosing the suitable alternative depend on customer requirements .For example, if time of construction is the governing issue then the slab bridge will be the chosen alternative. Otherwise, the box girder will be the adequate alternative if resistance torsion is the governing parameter. Moreover, in some cases it is hard to choose the appropriate alternative such as the case where the cost is the governing issue, because both of the alternatives have almost the same cost value so they are equally preferable.
