• Excavation for a services facility and crossover structure at Rosehill to allow provision for fresh air ventilation and emergency egress
• Tunnel portal and dive excavation at Clyde and a Stabling and Maintenance Facility
• Earthworks, retaining structures, drainage and utilities corridor for the Clyde Stabling and Maintenance Facility
