Graduates and Students: Challenges in design and construction of long bridge crossings, Hong Kong online

Please note that this webinar will be held from 11 Nov 2020, 19:00 – 20:30 HK time.

The design and construction of long span bridges and long sea-crossings have to overcome specific challenges that are often unique for each project, stretching the limits of engineering knowledge to achieve record-breaking span length, the use of new emerging technologies and innovative construction techniques.

Long-span bridges have always held a fascination for civil and structural engineers. The design for long span bridges is generally driven by project-specific site constraints and requirements. The design of each long span bridge is unique, with particular consideration required for the functional requirements (e.g. navigation clearance, vessel collision risk) and site conditions (e.g. ground, design loads) of the project. The bridge will need to address these specific conditions, and also being aesthetically pleasing as such bridges often become a landmark for the region. A balance often needs to be made between structural efficiency, buildability and aesthetics.

On the other hand, although long sea crossings often employ seemingly tried and tested design approaches and construction technologies, the engineering and solution is in fact different from project to project, driven by the need of a cost-effective solution and rapid construction method which can meet tight project programme, site constraints, environmental conditions and construction budget. These sea crossings can get particularly challenging if they are built in regions which experience extreme weather conditions and seismicity, or poor geotechnical conditions dictating the foundation.

In this talk, the three speakers from Arup will give an overview of the recent development and challenges in design and construction of long-span bridges and long sea-crossings, through selected projects they worked on across the globe. These range from feasibility studies, preliminary design to detailed design and construction supervision. These projects include the completed Hong Kong Link Road, Queensferry Crossing in Scotland, Temburong Bridge in Brunei and projects that are still at the design stage such as the Bataan Cavite Interlink Bridge in the Philippines.
