Lima Metro

Encardio-Rite provided geotechnical instruments for the Lima Metro, linking Lima and Callao. The project included advanced monitoring for underground stations and tunnels, using systems like automatic water pressure measurement, in-place inclinometers, concrete and shotcrete pressure cells, strain gauges, crack gauges, borehole extensometers, portable readout units, and dataloggers. These solutions ensured structural safety and performance, supporting a vital transport network for over eight million residents in the Lima metropolitan area.

Lima Metro

The Lima Metro, also called Tren Eléctrico, is a rapid transit system that serves the area of the cities of Lima and Callao, both of which make up the Lima metropolitan area, linking the district of Villa El Salvador in the south of Lima with San Juan de Lurigancho in the northeast of the same city.

It provides a transport link between different suburbs of the city with more than eight million people.

Encardio-rite supplied a comprehensive range of geotechnical instruments for monitoring the underground station and tunnel monitoring works. Instrumentation included:

Automatic water pressure measurement system (around 10 systems)
In-place inclinometer (around 408 sensors)
Concrete pressure cells (around 75 no.)
Shotcrete pressure cells (around 130 no.)
Arc weldable strain gage (around 160 no.)
Crack gage – mechanical (around 50 no.)
Borehole extensometer system (single point and multipoint – electrical – around 30 sets)
Portable readout units
Datalogger (around 21 no.)
