PROJECT DESCRIPTION

A 27km bridge providing new connetions and accessibility in Brunei without crossing borders with Malaysia. Innovative structural solutions were adopted for ease of construction, reduction of embodied carbon and environmental impact. For the marine viaduct, a new self-launching lifting gantry was created to erect two 50m precast full-span decks concurrently. This was the first time such a method was used.

Judge's comment:

At 27km long this vast bridge and viaduct is the longest in Southeast Asia. Connecting the two geographically separate parts of Brunei together, across both land and ocean, it aims to play a vital role in improving connectivity, accessibility, and economic development in the area. 

The towers for the two navigation spans combine classic Islamic architecture with the structural action of an A-frame but the apparently complex geometry was resolved structurally with straight lines and constant radius curves. This allowed well established formwork methods to be used for construction.

The viaduct through Temburong swamp was designed such that all construction activities, including pile installation, were carried out from the deck itself to minimise disturbance to the ground and environment. For the marine viaduct, a new self-launching lifting gantry was created to erect two 50m precast full-span decks concurrently, the first time such a method was used. 

The designers of Temburong Bridge have displayed creativity and deployed innovative structural solutions in an undertaking of enormous scale.
