| Abstract: | Many construction systems have been used to build several highway bridges and elevated roads in Egypt. Recently, the stepping shuttering system has been used in Egypt for cast-in-place concrete bridge. This system is most appropriate for concrete bridges of moderate spans ranging from 40 to 70 m. The stepping shuttering system provides appropriate means to satisfy local needs for concrete bridge construction in an urban environment, practically without infringing on traffic or property below. This paper presents an innovative method of construction that has been used in Egypt for the first time to build the 6th October Bridge extension. Issues regarding the constructability and innovation are highlighted, and the significant aspects during the bridge construction are documented. Also, the difficulties encountered and the lessons learned are thoroughly investigated. In addition, evaluation of the system is discussed in terms of construction cost, schedule, and flexibility. Finally, this paper presents an innovative method that offers substantial opportunity for enhancing constructability of concrete bridges using the stepping shuttering system. |
