Designing four underground stations as part of an orbital link connecting all rapid transit lines into the city

The Circle Line (CCL) is a new orbital link connecting all the existing radial Rapid Transit System lines running into the city. It is sponsored by the Land Transport Authority of Singapore, estimated at S$6.7 billion. The CCL will be a fully underground orbital system. It will have interchange stations with the existing North-South and East-West lines, as well as the North-East Line, to provide better connectivity and convenience to commuters. The CCL is 33.3 km long with 29 stations. Starting from the Dhoby Ghaut station, it will run through some of the busiest corridors in the city and end at Harbour Front station on the North-East Line.

Stantec completed the detailed structural, architectural, electrical, and mechanical design of four underground stations, namely: Bartley, Serangoon, Lorong Chuan, and Marymount. Bartley and Lorong Chuan stations are both designated as Civil Defence underground structures. In the process, we designed alignment of 5.7 km of twin bore TBM driven tunnel. 

Our design services continued through tender, permitting, construction and commissioning of the project, including temporary works review.
