Our Role

SMEC provided tender design services including design of permanent and temporary works for the 2.3 km tunnels, cross passages and the Hillview and Beauty World station cut and cover box option.

Project Overview

The project consisted of construction of twin bored tunnels between stations at Hillview and Beauty World in Singapore.

The length of bored tunnels was approximately 2.3 km and the tunnel separation varied from 12 m to 27 m.

A launch shaft and cut and cover tunnels had been constructed in the vicinity of Hume Avenue (30 m long and 25 m wide) which also had to be connected to the new tunnel.

All the railway operating systems, ventilation systems, track work and traffic management systems were based on Singapore's Land Transport Authority requirements.
