Cross Island Line — CR110 / CR115

Overview

Contracts CRL110 and CRL115 continue the Cross Island Line's bored-tunnel drives with a mixed fleet: a 12.6-metre earth-pressure-balance machine on the large single-bore section and three 7.2-metre EPB machines on the twin-bore running tunnels.

Our crew members supported these drives across the machine lifecycle — from shaft logistics and shield assembly through production mining to maintenance interventions — building the deep familiarity with CREG EPB machines that we now bring to new contracts.

Scope of Works

• Shield and gantry assembly in launch shafts
• EPB mining operations and face-pressure control
• Segment erection and annulus grouting
• Planned maintenance and cutting-tool changes
