Description

In September 2015, the Jakarta city government began the construction of the Jakarta Light Rail Transit (LRT) system in Indonesia’s capital Jakarta. The Light Rail Transit was launched as a substitute for the 2004 Jakarta Monorail project that was cancelled by the Jakarta administration as it failed to meet certain conditions. LRT is an eco-friendly and rail-based means of transportation that will operate above roads and highways.

The LRT is built with the purpose of connecting the centre of the city with suburban regions, such as Bogor and Bekasi, and therefore providing a transport system of international standards. On September 9, 2015, the first phase has started, which includes the construction of three lines: Cibubur - Cawang (13,7km), Cawang - Dukuh Atas (10,5km) and Bekasi Timur - Cawang (17,9km). The second phase includes lines between Cibubur – Bogor, Dukuh Atas – Palmerah Senayan and Palmerah – Grogol. Although the project was planned to finish in time for the Asian Games in 2018, it is scheduled for completion by 2019, according to Transportation Minister Budi Karya Sumadi.

Eventually, the LRT will offer a new system of mass transportation that is expected to ease the congestion of Jakarta’s gridlock traffic. The used precast technology is one of the world’s most resource-efficient ways to build and ensures higher quality and faster construction times. Beyond that, it is used by countries such as Singapore, China, Hong Kong and Japan. Sumadi added that the infrastructure of the LRT also accommodated fibre-optic communication and phone lines. On that account, and due to the use of precast, Indonesia would be more advanced.

For the construction of the Light Rail Transit, 30 meter long concrete troughs are cast in 12 forms simultaneously every 18 hours and anchor channels are installed at 1.5 meter centers in a vertical position. Installation is performed by welding an L-bracket to each end of the anchor channel. Each L-bracket has a hole through which bolts are placed and used to fix to the metal forms. The L-brackets also effectively seal the ends of the anchor channel and prevent concrete from seeping in.
