Corridor 13, Jakarta: a new Viaduct in the Seskoal Section

Corridor 13 is a new, 9.3 km long, elevated roadway for buses in Jakarta, Indonesia, that leads from Ciledug to Jalan Tendean. A 1,400 m long viaduct is being erected in the Seskoal section, one of 8 sections of the new busway. The viaduct has to be built in a highly frequented area while traffic is running in limited space both day and night.

In order to comply with the limited schedule and to reduce traffic obstruction to a minimum, decision was made to build the segmental box girder bridge using the span by span method with an overhead launching gantry.

The individual segments are glued together with epoxy resin and then connected using short, temporary bar tendons. The permanent prestressing forces are applied to the structure via external post-tensioning tendons. Despite the fact that work is only possible at night, the team of DSI licensees achieves a cycle time of 4-6 days per span.

600 precast box girder segments

Approximately 600 precast box girder segments are installed in total. The box girder and the pier heads are strengthened by internal and external DYWIDAG strand tendons with anchorages using 360 t post-tensioning strand. Short bar tendons are also used for temporary stressing.

PT Delta Systech Indonesia actively accompanied the project from the design to the construction stages and suggested an innovative and efficient solution. Furthermore, PT Delta Systech Indonesia supplies and installs internal and external post-tensioning tendons. A Joint Venture consisting of PT Delta Systech Indonesia and DYWITECH Co. Ltd., Taiwan is responsible for operating the overhead launching gantry and provided engineering services.
