| Abstract: |
This paper highlights the challenges faced in large urban bridge infrastructure projects, including excessive material consumption and negative environmental impact. It focuses on the optimization process conducted for a new pair of railway double-track bridges in Tel-Aviv, Israel, featuring continuous prestressed concrete box girders. The design works began in late 2020, with construction currently underway. COWI was responsible for the superstructure design packages, optimizing the box section, resulting in increased post-tensioning design efficiency and a 30% reduction in materials. Through careful planning and teamwork with the contractor, the project achieved lower carbon footprint, decreased cost, and increased speed of mobilization. |
