Effect of the superstructure construction method on the cost and duration of bridge projects in Sudan

Abstract EN

Sudan, being a wide country consisting of sixteen states, in which thousands of kilometers of waterways and valleys are extended, bridges had become desperately needed for proper communication and development.

There were many types of bridges in Sudan made of concrete, steel, and composite sections showing various types of suspended, steel truss, arch, and cable-stayed bridges which were constructed by different methods.

This paper summarizes the data of main bridges in Sudan; it shows the construction duration, cost, and type of the superstructure and presents a comparison between bridges’ superstructure construction methods in terms of cost in US$ per m2 of the bridge plan area and production rate in m2/week.

The paper also recommends the most favorable bridge construction methods that are expected to contribute better into saving cost and construction time.
