Taisei Corporation
Contract T226 for the design and construction of Marina Bay TEL Station and associated tunnels was awarded to Taisei Corporation at a sum of S$425 million (US$ million) in February 2014. Construction started in 2014, with expected completion in 2022. The construction involves the demolition of the East Coast Parkway and Marina Station Road, which also affects the adjacent Shenton Way station. Ground freezing was applied for the first time in Singapore rail construction when building the Thomson–East Coast line part of this station, where it crosses underneath the existing North South line and Circle line tunnels.
