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

After almost a decade of dwindling activity, the uptick has heartened the construction industry, which would build the supporting infrastructure.More than 230 nuclear reactors worldwide are either under construction or in the planning stages, helping to fuel demand for uranium. Another 200 nuclear powerplants are due for decommissioning and, the industry hopes,

The city and its suburbs have long been challenged by a limited water supply, but the very real effects of climate change are exacerbating and accelerating already dry conditions. The region's 2 million residents depend almost entirely on the Colorado River, yet its lake-stored flows are set to dwindle significantly in the next few decades.Located about 30 miles from the city's downtown, Lake Mead's depth has sunk to perilously low levels—
