A UK firm is to supply an innovative gantry for use in construction of a 13.7km long bridge in South East Asia.
Dorman Long Technology will provide an 840t deck erection platform to main contractor Daelim-Swee for the Temburong Bridge project in Brunei.
The 130m long gantry will be used to simultaneously erect two 50m long, 870t precast concrete bridge deck girders.
The project will see a marine viaduct built across Brunei Bay to link Bandar Seri Begawan with Temburong.
The gantry will be delivered next April and is expected to be in operation on the project for two years.
It is designed to provide a fast and economic solution for the erection of twin deck marine viaducts where the water depth along the length of the bridge is sufficient for barge delivery of the deck girders.
The gantry takes delivery of two bridge deck girders from a pair of barges and uses four strand jacks for lifting.
The girders are then moved sideways into final position and smoothly set down on the bridge bearings.
