Bogor Outer Ring Road, Indonesia

Bogor Outer Ring Road is a 11 km long bypass that circles the centre of the city of Bogor in West Java, Indonesia. The highway allows traffic to bypass the road network in the centre of the city, permitting a faster connection to Jakarta and Soekarno-Hatta Airport.

The project is divided into three sections, the first of which, a section that is just less than 4 km long, was opened to traffic in 2009. At the moment, the second, 4 km long section is under construction. The third section with 3.2 km length is currently in the planning phase.

In section II, DSI licensee PT Delta Systech Indonesia supplied and installed external and internal DYWIDAG Strand Tendons for several new elevated highways. PT Delta cooperated with DYWITECH Co. Ltd., Taiwan, to supply and operate the launching gantry for the erection of the precast segments using the span by span method and to provide technical support.

The launching gantry was designed by Wiecon engineering consultants, Taiwan, with a fully automatic system using an electric winch to lift the precast segments and a hydraulic system for launching the segments, so that overall construction time was reduced.

Hollow box girders consist of 1,000 precast segments

In total, the hollow box girders of the new elevated highways consist of approx. 1,000 precast segments. The box girders and pier heads were post-tensioned using internal and external strand tendons. More than 1,150 t of Type 0.6" strand was used for the strand tendons on this project. In addition, Ø 32 and 36 mm bar tendons were used for permanent stressing, temporary stressing and for hanging the segments during erection work.
