The 5.4km Marina Line or the first stage of the Circle Line is a fully automated, wholly underground medium capacity system in Singapore. The Marina Line comprises six underground stations and interconnecting tunnels.
Contract 824 calls for the design and construction of 2 cut and cover stations Nicoll Highway Station and Boulevard Station; 1.25km of cut-and-cover tunnels as well as 0.75km of twin bored tunnel.
CPG teamed up with one of the world's leading transportation and infrastructure consultants, Halcrow Group Limited. The architectural design team ensured that the social, functional and technical needs of the underground network were fully addressed when designing the stations.
