Design of 1000m of elevated viaducts carrying the upgraded Jalan Sungai Besi Carriageway over KL-Seremban Highway, the existing live KTM and Future ERL Railways at Salak Selatan in Kuala Lumpur.

The  viaducts consist of  prestressed  concrete  precast segmental box girders  continuous over 38 m spans constructed using the balanced cantilever method.  The segments are erected using mobile cranes and the balanced cantilevers are stabilised during launching using a temporary structural steel prop/tie system supported off the permanent works pilecaps.

Design was commenced on 1st April 1998 with viaduct construction completed in January 1999, under a year from our appointment.

The project includes two innovative alternative designs for widening below the Kampung Malaysia and Turf Club Bridges. New displaced piers were constructed for the Kampung Malaysia Bridge with new crossheads prestressed onto the existing without interrupting traffic on the bridge. For the Turf Club Bridge, the existing 10m end span was replaced by two spans of 20m and 10m lengths constructing using the top down technique thus maintaining traffic flow over the bridge throughout the works.

RB was appointed by the contractor as the bridge specialist designers, also providing shop drawings, alignment control, temporary works and construction technology services.
