The Land Transport Authority (Lta) of Singapore has awarded two civil contracts for Cross Island Line-Punggol Extension (CPe) and bored tunnel for Cross Island Line Phase 2 (CRL2).

Woh Hup secured the first contract worth about $367.1m (S$496m) to design and build the Punggol interchange station, located along Punggol Central, under the CPe.

The scope of work on the project includes addition and alteration works to the current Nel Punggol station.

This will allow seamless transfer and improved connectivity between NEL, LRT and the new CPe station.

Currently, Woh Hup is working on the construction of Tanjong Katong and Bayshore stations for the Thomson-East Coast Line (TEL), Loyang station on the CRL as well as on the Kim Chuan Depot Extension.

A joint venture (JV) between Obayashi Corporation and Shanghai Tunnel Engineering received the second contract worth approximately $561m (S$758m) to design and build the bored tunnel between Fairways Drive and Sin Ming Walk under the CRL2.

LTA stated that a 2km stretch of the bored tunnel alignment will undercross the Central Catchment Nature Reserve.

The tunnel will be built up to nearly 70m depth below the ground level.

Previously, a comprehensive Environmental Impact Assessment was carried out by LTA.

LTA will also implement all the necessary mitigation measures that were mentioned in the Environmental Monitoring and Management Plan.

Construction works related to the bored tunnel between Fairways Drive and Sin Ming Walk for CRL2 and the CPe Punggol interchange station are anticipated to commence in the first half of next year and passenger service will begin in 2032.
