The large scale Mass Rapid Transit (MRT) project in Jakarta is the first light rail project in Indonesia and is expected to significantly reduce traffic congestion. In 2013, the first, approx. 16 km long section of the North-South Corridor from southern Lebak Bulus to the Hotel Indonesia in the city center was opened.
The second phase of the MRT is 8.1 km long and leads to Kampung Bandan in North Jakarta. The section includes 6 subterranean stations and 7 elevated stations.
Bridge with tight radius
In section CP 102, an elevated bridge that crosses the heavily trafficked Jakarta Outer Ring Road is being built using the balanced cantilever method. The bridge is 173 m long and has a tight radius of 182 m.
PT Delta Systech Indonesia was awarded the post-tensioning work as well as the rental and operation of the form travelers. DYWITECH Taiwan supplied 4 sets of form travelers for the construction project. The limited space posed a challenge for the assembly and the use of the form travelers.
A total of 68 t of strand post-tensioning tendons with MA Anchorages were installed in the balanced cantilever bridge. Post-tensioning bars were used for form traveler operation.
