Liga Asuransi<\/a> – <\/span>Dear readers, how are you? Let’s continue our discussion on risk management and insurance, this time we will be discussing the risks of tunnel construction work.<\/span><\/p>\n

Indonesia has a strong commitment to building a large amount of infrastructure to increase economic growth and people’s welfare, the government has built several tunnels for transportation and is still to build more infrastructure projects.<\/span><\/p>\n

As a senior insurance broker<\/a><\/b>, here we want to share with you the risk review and insurance consideration for the tunnel construction project.<\/span><\/p>\n

We hope that this can be of assistance to you in anticipation of the risk of such kinds of projects. If you are interested, please share it with your colleagues so that they also understand as you do.<\/span><\/p>\n

As you might be aware that one of the sizable tunnel projects currently under construction is the Jakarta Bandung high-speed rail line known as the Indonesia China High-Speed Train (KCIC) project, it has a total of 13 tunnels.<\/span><\/p>\n

The history of railway tunnel construction in Indonesia has started in the 19th century, starting with the construction of railway tunnels in the Ranah Minang, namely:<\/span><\/p>\n

    \n
  1. Anai Valley 1, 1890-1891 with a total of 100 m, Padangpanjang – Anai Valley, West Sumatra.<\/span><\/li>\n
  2. Anai Valley 2, 1890-1891 200 m Padangpanjang – Anai Valley, West Sumatra.<\/span><\/li>\n
  3. Kupitan 1892, 894 600 m Muara Kalaban – Padang Sibusuk, West Sumatra.<\/span><\/li>\n<\/ol>\n

    Meanwhile, the construction of toll roads in Indonesia has now also gone through tunnels. Some are already completed, and some are yet still to be built.\u00a0<\/span><\/p>\n

    The following is a list of tunnels for toll roads in Indonesia:<\/span><\/p>\n

      \n
    1. Yogya – Bawen Toll Road section 5 from Temanggung to Ambarawa will be built a tunnel through the hilly area, precisely STA 20 + 300 to STA 20 + 800.<\/span><\/li>\n
    2. Cileunyi – Sumedang toll road – 472-meter long with a diameter of 14 meters.\u00a0\u00a0<\/span><\/li>\n
    3. The Padang – Pekanbaru toll road uses tunnels to Barisan hills in Sumatra with a total length of up to 8.95 kilometers.<\/span><\/li>\n
    4. Palembang – Bengkulu Toll Road uses tunnels to penetrate the Barisan hills in Sumatra.<\/span><\/li>\n
    5. The 95 km Linggau – Curup – Bengkulu toll road has a tunnel to penetrate the Bukit Barisan area.<\/span><\/li>\n
    6. Submarine Tunnel Toll at New Capital City (IKN) in Penajam, Kalimantan. To connect the IKN area in Penajam Paser, East Kalimantan, an undersea tunnel toll road will be built. Which is connected from the Balikpapan – Samarinda toll road.<\/span><\/li>\n<\/ol>\n

      As we all know that every construction project is always faced with the possibility of various occurrence kinds of risks. The higher the level of complexity of a project, the greater the level of risk that might happen to the project.<\/span><\/p>\n

      Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the groundwater conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use, and the shape of the tunnel and appropriate risk management. Tunnel construction is a subset of underground construction.<\/span><\/p>\n

      Mostly, tunnels are underground passages used for transportation. They could be used for carrying freights and passengers, water, sewage, etc Tunnels are more economical than open cuts beyond certain depths. Tunnels avoid disturbing or interfering with surface life and traffic during construction<\/span><\/p>\n

      There are three major risks associated with tunnel construction projects:\u00a0<\/span><\/p>\n
