Managing Challenges and Mitigating Risks in Design, Construction, and Product Conformity of the Shared Path Bridge over Epping Road at Marsfield

This paper identifies the challenges and risks in the design, construction, and product conformity of shared (pedestrian and bicycle) path bridges. Also, the paper describes how these challenges were managed and the risks mitigated. The biggest challenge in the design of this project was the erection of the superstructure with minimum disruption to the traffic. The steel arch structure was designed to span 42 m over the width of 6-lane carriageways plus the median on the busy Epping Road at Marsfield. This was further complicated when the fabricator proposed procuring circular hollow sections from other economies that generally use a steel that is manufactured to other national standards without providing enough evidence of compliance to Australian product standards. This could jeopardize the validity of design that was undertaken in accordance with the Australian bridge design standards. The project was designed and managed by a multidisciplinary team from Roads and Maritime and constructed by a contractor who subcontracted the fabrication of the steel arch, deck, and other minor steelwork.
