Description
Design and construction of a viaduct superstructure of the Bukit-Panjang LRT system, including provision of labor, precast and erection equipment, and engineering services.
The 7,7 km-long elevated line includes 14 stations, providing easy passage and connection to other means of transportation in the city. The fully-automated service runs with 2-4 minutes frequency during peak hours, and 6 minutes frequency during the rest of the day.
The project faced several technical challenges: in particular, the elevated guideline was often located in close proximity to high-rise residential buildings, with a tight tunrning radius (down to 60 m). Construction also required numerous diversions of underground services.
The segmental construction method, with the use of launching girders, was firstly introduced in Singapore with this project.
