Construction for Singapore's High-speed Rail to Start in 2019
Singapore's Land Transport Authority (LTA) has called tenders for the design and construction of tunnels and associated facilities for Singapore's end of the high-speed rail project connecting with Kuala Lumpur.
Construction is expected to start next year.
"We called the tenders for the design and construction of twin bored tunnels and associated facilities on April 6, and the design and construction of cut and cover tunnels leading into the Jurong East terminus on April 11," an LTA spokesman said.
The tunnels are constructed using tunnel-boring machines, which are preferred for longer stretches of underground excavation as they cause less disturbance to surface utilities, buildings and structures.
In comparison, cut and cover tunnels are constructed using retaining structures, then excavating in stages.
This method is preferred for shorter distances and in open areas with fewer surface utilities, buildings and structures.
The LTA said the remaining civil tenders will be called in the coming months, and construction work is expected to commence next year.
The governments of Malaysia and Singapore signed an agreement late last year to embark on the project. According to the bilateral agreement, the HSR link is expected to become operational by Dec 31, 2026, and will cut travel time between Kuala Lumpur and Singapore to just 1½ hours, down from about four hours by car.
