1.- WHAT IS TECFOS?
The Training and Technological Applications Development Centre in Underground
Construction is implanted based in the experience of Santa Barbara Foundation during
its 20 years of operation in collaboration with Universities, Technological Centers and
leader companies, constituting an open consortium created from 2008 with the goal to
respond, through training programs and applicated investigation lines, to the needs
surging from companies and public administrations related to underground construction

Fire Test Gallery
The Fire Test Gallery has a 10 m2 cross section, and its length is 110 meters. The
beginning and the end of the gallery is covered with concrete rings, and its middle
section consists of hard rock bolted supporting system. The gallery is also served by a
110 KW ventilator with a remote controlled frequency regulator, allowing the control of
the air velocity inside the installation. Remote controlled doors can be opened or
closed, according to the ventilation requirements.
Control Rooms. Communications.
Monitoring and Control of underground infrastructure is centralized in two control rooms
using an optical fiber network to provide communication between the sensors and
actuators, and the SCADA software installed in them. This supervision and control
system provide the following capabilities:
1. Monitoring and control of the ventilation system in tunnels and fire test gallery.
2. Remote controlled doors in the ventilation circuit.
3. Monitoring large number of sensors (temperature, pressure, air velocity, gas
control) and remote operational performances.
4. Video supervision of the works and tests made in the infrastructures. Network
Dome IP cameras PTZ working even in low luminosity (minor than 0.005 lux).
5. Radio communication system and Wi-Fi real time location system.
