Speedy Precast Segment Casting

Penang Second Crossing

Precast segment casting has been recently completed, 100 days ahead of schedule, by BBR Malaysia of The Penang Second Crossing. There are two bridges in total, one for each direction of traffic flow. Each bridge comprises of precast box girder segments with external post-tensioning.

BBR Malaysia was engaged to match cast the precast segments with dimensions 14 m wide x 3.2 m high x 4 m deep. By casting against the previous cast segment, the joint matching of shear keys was assured during segment erection and installation.
Completed segments weighing between 80-100 t were delivered to the working fronts by barge and then erected by launching gantries using a span-by-span erection method. When completed, a total of 8,092 segments will have been erected for the 16 km crossing.
