Japanese Contractors Tackle Jakarta's $1.8-Billion Mass Transit Program
In a little more than 18 months, Indonesia’s capital, Jakarta, has become unrecognizable as the $1.8-billion Mass Rapid Transit project continues to cut a deep scar across the city. With 13 stations—seven elevated, six underground—along with a rail depot, the project features the construction of both cut-and-cover and bored tunnels, the latter using tunnel boring machines (TBMs) where space restricts deep excavations. With deep secant pile support and precast segmental pre-stressed viaducts also a feature, the project brings to Indonesia a host of construction technologies rarely seen in the archipelago.
