Aplitop and Spectra Geospatial Collaborate on Tunneling Survey Solution

Aplitop Tcp Tunnel Software Now Works with Spectra Geospatial Focus 35 Total Station

Málaga, Spain. Aug. 4, 2020- Aplitop announced today a collaboration with Spectra Geospatial, an established brand known for delivering quality products to the survey, GIS and construction markets, to provide a comprehensive tunnel survey solution to increase productivity for survey service providers.  

This collaboration provides surveyors and geospatial professionals with a complete hardware and software solution for performing efficient tunnel construction surveys. Combining the accuracy and speed of the Spectra® Focus® 35 robotic total station with the simple workflows of Aplitop TcpTUNNEL, running on the ST10 or Ranger 7 data collector, enables tunnel surveyors to perform excavation control, automated survey and stakeout of tunnel cross-sections. In the office, data and designs can be transferred seamlessly between TcpTUNNEL CAD, a plug-in for several CAD platforms, and TcpTUNNEL field software.

The Spectra Geospatial and Aplitop solution provides a full featured workflow for tunnel constructions surveys including:

- Definition of the project design elements such as alignments and templates that can be easily transferred between the field and office 

- Efficient tunnel drill and blast setout as well as reporting on the difference to design positions

- Automated data collection for the quality control of tunnel excavation process using cutting-edge tracking mode

- Accurate stake out of key design features and anchor bolts along tunnel alignment

- Graphical reporting of the differences between design and survey data to calculate over and underbreak volumes and areas to ensure design conformity

“We are excited to partner with Spectra Geospatial to introduce a solution for tunnel construction professionals,” said Francisco Navarrete, general manager of Aplitop. “This combined solution enables professionals to leverage the speed and accuracy of Spectra Geospatial total stations with the simplicity of the TcpTUNNEL portfolio.”
