Trimble Australia  announces the introduction of a new integrated office to field positioning solution that aims to make tunnelling safer, faster and less expensive for tunnelling contractors.  

Trimble SCS900 Site Controller Software Tunnelling Module leverages Business Center – HCE office software powered by Trimble and operates on the Trimble Tablet as well as the Trimble SPS930 Universal Total Station. Part of the Trimble Connected Site portfolio, the integrated tunnelling solution allows contractors to quickly, safely and accurately perform tunnel construction, while monitoring progress in real-time.  

The Business Center – HCE Corridor Tunnelling module is the starting point for efficient tunnel construction operations with the preparation of an accurate model. Contractors can use the sophisticated tools of the module to model tunnels with multiple layers all in the same alignment. Business Center – HCE tunnelling tools handle extremely complex design and measurement files, including multi-million point cloud files from LIDAR devices, and accommodate drilling and blasting operations.  

The complete tunnel model can then be exported to the Trimble Tablet running SCS900 Site Controller Software in the field.  

Tunnelling contractors using Business Center – HCE office software have the ability to send accurate, up-to-date designs to the field wirelessly, eliminating the need to physically drive to the site. Data preparation with Business Center – HCE and an accurate model can help the tunnelling contractor identify and resolve potential problems before the project starts, saving time and money.  

Using Trimble SCS900 Site Controller Software with a Trimble Tablet, tunnelling personnel in the field can compare the 3D tunnel design with the as-built tunnel after every blast round. Contractors can more efficiently address the daily measuring and positioning requirements of road and railway tunnelling projects, while reducing the work stoppage time for manual measurements and monitoring progress from a safer distance from the blasting zone.  

SCS900 can be used for all measurement and stakeout operations inside and outside the tunnel including rock bolts, cable and ductwork, tunnel floor and wall measurements, and drainage or utility information.  

The Trimble Tablet allows crews to wirelessly receive design changes or updates in the tunnel and to quickly deliver measurement results back to the office for rapid approvals, enabling site engineers to rapidly communicate on-site problems, take remedial actions or request information from the project engineers without driving to the office.  

The Trimble SPS930 Universal Total Station provides high-accuracy positioning for tunnel construction projects. The SPS930 uses its advanced robotic scanning capabilities to enable field crews to operate at safer distances from scaling operations and provide a more accurate measurement of results. Integration with tunnel-specific scanning routines in the SCS900 Tunnelling Module produces a more accurate profile of the tunnel surface.  

All components of the new Trimble Tunnel Construction Solution are expected to be available in May 2012 through Trimble’s worldwide SITECH Technology Dealer Channel.
