The CR115 Project is part of Singapore's Cross Island Line (CRL), which aims to enhance connectivity and provide a comprehensive underground transport network across the island. The project involves the design and construction of Tavistock Station, an underground Civil Defence Station, as well as the associated tunnels. This key section of CRL Phase I is focused on connecting residential and industrial areas in the eastern and north-eastern corridors, improving access to vital hubs like the Punggol Digital District and serving over 100,000 households.

For this project, Unicrane has supplied 2 sets of left taper ring molds and 2 sets of right taper ring molds with the specification OD 6.9m × 1.4m × 0.3m (7+1P/R), crucial for producing high-quality tunnel segments for this major infrastructure project.
