Tunnelling

The Land Surveys team is qualified to carry out GYRO Surveys to strengthen the absolute position and alignment of the tunnel.

Using a mixture of conventional and modern survey techniques, our experienced surveyors can successfully help build shafts from excavation, through shotcrete, to final lining.

Our experienced Tunneling Surveyors can control a variety of TBM guidance programs. By maintaining a robust control system through daily traverse and equipment checks, our surveyors output a guidance system which follows steadily close to the design position.

Our application of the most efficient and innovative methods can help minimise access time in these existing condition environments, saving you money and time in obtaining as-built, or as-found datasets for your project.

Tunneling survey solutions we can deliver to your project:

• Achieve optimal conformance of excavation, shotcrete and final lining layers
• Using state-of-art software such as Amberg Technologies
• Quickly produce top quality user friendly reports
• Existing conditions or as-built rapidly using 3D laser scanning

• Real-time structure and geo technical monitoring

Our Tunneling services can be applied to:

• Road headers
• Drill and blast
• Tunnel Boring Machine (TBM) guidance
• Shaft alignment
• Subsidence monitoring
