CR102 - New video from LTA

Today, the Land Transport Authority (LTA) released a new animation video detailing the works required under contract CR102. This contract involves the construction of tunnels between Aviation Park station, the Changi East Cross Island Line (CRL) depot and tracks towards the future Terminal 5 station at Changi Airport. Tunnel Boring Machines (TBMs) will be used to bore 5 tunnels - 2 mainline running tunnels & 3 reception tracks at a T-junction.

According to the video, ground improvement works are required before excavation and tunneling can begin. A further challenge to construction is that it will take place in close proximity to a live aviation environment which limits the height of machinery that can work in the area. However, the contract is being undertaken by Shanghai Tunnel Engineering Co (STEC), who also won contract T316 for works on the Thomson-East Coast Line, also within the Changi Airport area. Thus, STEC should be no stranger to the restrictions of working within a live aviation environment. We wish the contractor well as works get into full swing for the CRL tunnels.

Contract CR101 & CR102 are included & essential for the construction of Cross Island Line (CRL) phase 1. The first of the 2 contracts involves the construction of the Changi East Depot while the second will see the construction of tunnels from the depot and linking to both Aviation Park station & the future Changi Airport Terminal 5.

Pre-construction: Changi East depot

The main depot for the Cross Island Line (CRL) will be located at Changi East, bounded by Aviation Park and Tanah Merah Coast roads. Currently the land sits as an undeveloped, vegetated portion of reclaimed land along the coast. Come 2021 however, works will begin to transform the land into an operational depot supporting the operations of the CRL.
