Surveying Application

Performs simple and accurate execution control for tunnel projects for roads, railroads, subways and mines, with total station or 3D scanner.

Construction field solutions




Control of tunnel works with total station

TcpTunnel can be installed in a wide range of motorized total stations, or in a data collector.
The cross sections are measured automatically, simply giving the desired interval and the number of points per profile. The application shows the theoretical and measured tunnel section, with top and front views displaying infra and over-excavation areas.
It also has functions for setting out the front, pavement or tunnel profiles, checking control points, calculating areas, etc.


TcpTunnel Scan for Topcon


Real-time Control Tunneling Software

TcpTUNNEL Scan installs on a Windows tablet connected to the scanning robotic total station TOPCON GTL-1000.
The software commands the scanning of the tunnel vault or face and show the point cloud in a powerful 3D viewer. High definition tunnel cross-sections are calculated, and they can be compared to the tunnel design, showing the underbreak and overbreak areas. Selecting any point of the profile on the screen, the laser pointer marks the position in the tunnel and vice versa.
TcpTUNNEL Scan facilitates the stake out of the tunnel front, for example the drill hole points for the next blasting excavation sequence, points on the template, rock bolts, road surface and more.


TcpTunnel for Spectra Geospati


Tunneling Survey Solution

TcpTunnel for Spectra Geospatial installs on a Windows tablet with Bluetooth interface connected to Spectra Geospatial FOCUS 35 total station.
The cross sections are measured automatically, simply giving the desired interval and the number of points per profile. The application shows the theoretical and as-built tunnel sections, with top and front views, displaying underbreak and overbreak areas.
The program allows the staking out of the funnel face, points of the tunnel template, rock bolts, road surface and more.

Office solutions


OS Android


Analysis of tunnel data measured by total station

This CAD application processes tunnel surveying data measured by total stations running TcpTunnel or other programs.
TcpTunnel CAD calculates from the points and alignment the cross sections, that can be filtered and edited, and allows you to compare with the tunnel template drawn as a polyline. You can also draw profiles in single or sheet mode with multiple customization options, as well as generate the 3D model of the tunnel.

The application also calculates infra or over-excavation areas and volumes, generating reports that can be printed or exported to various formats.


OS Windows


Analysis of tunnel data captured by terrestrial scanner

This powerful application calculates tunnel cross sections for roads or railways, based on laser scanner data.
Starting from the point cloud, cross sections are calculated, which can be modified by a powerful editor. They can be displayed in 2D or 3D, showing the infra and over-excavation zones, and can also be exported to DXF, with multiple customization options.

The program also generates other results such as area and volume reports, deviation of the real alignment, inspection map, orthoimages and video simulation of the tunnel.
