Managing the size
Building a bridge with such a huge span exposed to strong typhoon winds, posed many challenges to the Arup design team, including advanced analyses of wind patterns at the site and mitigating against potential ship impact.
This was in addition to challenges relating to working at such a large-scale and height, whilst also ensuring minimum disruption to shipping traffic.
Because of its sheer size, accurate dimensional control is essential to ensure that all parts of the bridge fit together as designed. This requires great control during casting of concrete elements and prefabrication and assembly of large-scale steel elements that make up the deck.
The most challenging aspect of construction was the coordination between the various elements of the bridge. Close coordination was required between the temporary and permanent works and between on-site and off-site construction.
