JTC Corporation has called a tender for feasibility studies for an underground goods movement system.
It is asking for at least three tunnel alignments to link the future container port in Tuas to the industrial estates at Tanjong Kling, Jurong West and Gali Batu. This includes looking at the depth, space allocation and maintenance, Channel NewsAsia reported.
The project - a first for Singapore - is expected to facilitate the movement of goods from point to point without relying on roads, therefore potentially relieving traffic congestion.
The move is expected to optimise use of surface land for industrial purposes and other supporting facilities. Experts believe the underground goods movement system will be automated, with conveyor belts and self-driving cars being possible options. They said Singapore is ready for such a system given its experience in tunnelling work.
Besides the tunnel, there are also plans to construct another cavern in Jurong - this time, in Jurong West. Factors being considered include the ventilation system for the underground facility and the industries that can be housed there.
The tender for the entire project closes on June 12, 2015.
