Our services have been involved with the monitoring of over 500 km of rail-road tunnels in the toughest terrains, ranging from geologically complex Himalayas to the soils of Europe. Platamonas Tunnel, Egnatia Motorway including Anilio and Anthochori tunnels, Pir Panjal tunnels are just some of the projects we have been involved with.

Details of few of our projects instrumented by us worldwide are given below:

Pir Panjal Railway Tunnel


Location: Jammu & Kashmir
Client: IRCON
Contractor: HCC
Consultant: GC-Rites

Rail-road tunnels in one of the rugged terrain of Pir Panjal Mountains in Jammu & Kashmir, India. The tunnel section is a part of the 202 km Udhampur - Srinagar - Baramulla rail link project undertaken by the Northern Railways. It operates 440 m below the existing Jawahar Tunnel, which is the only road link from the region to the rest of India.

Encardio-rite instrumented supplied and instrumented 11 Km long Pir Panjal Railway tunnel (T-80: 8.4 m wide and 7.3 m high) one of the India's longest and Asia's 2nd longest transportation railway tunnel. The tunnel became operational in October 2009.

Sheikh Zayed Tunnel


Location: Abu Dhabi
Length: 4.2 km

Salam Street now renamed as Sheikh Zayed bin Sultan Street is one of the main roads in the city of Abu Dhabi. It starts from Sheikh Zayed Bridge and curves its way around Abu Dhabi's eastern end until it ends at the intersection with Corniche Road. Salam Street runs through the main modern shopping area and Robat Street, the new bypass north of the town.

Encardio-rite bagged the contract for supply and services of Instrumentation and Monitoring and successfully instrumented as planned.

Encardio-rite is proud to be associated with the Shaikh Zayed street and Shaikh Zayed tunnel project that transformed Abu Dhabi. The Shaikh Zayed tunnel project prepared the city to the occupancy of the neighboring new development in Al-Reem Island and Al-Sowwah Island. Encardio-rite supplied, installed and monitored a no. of instruments in the 3 Km. long road tunnel project including Bore Hole Extensometers with packer anchors, Inclinometers, magnetic extensometers, strain gages, load cells for struts/anchors, standpipe piezometers, portable tilt meters, fixed tilt meters, building/surface settlement points and optical targets. Our scope also included the review and comparison of collected data with set values, analysis of data with interpretation/recommendations and submission of weekly reports.

Udhampur Srinagar Baramulla Rail Link (USBRL), J & K


Location: Konkan, India
Owner: Govt. of J & K
Contractor: KRCL

USBRL project is one of the largest and most challenging railway projects in the world. The 312 km railway line is being built from the city of Udhampur, North of Jammu to the city of Baramulla at the North Western Edge of the Kashmir Valley. Udhampur is already connected to the rest of India through Jammu. The railway line will thus connect the Kashmir valley to the rest of the Country. Encardio-rite is instrumenting 20 large tunnels on this rail link project, including the around 11 km long Pir Panjal Tunnel. The toughest section of this stretch is the 90 km long Katra to Laole section in which 80 % of the railway line passes through a tunnel or is on a bridge. IRCON, Indian Railways and Konkan Railways are in-charge of executing the various sections of this massive project.

Besides supplying the instruments, Encardio-rite is also doing the installation and monitoring of the data through a large number of qualified, trained and experienced engineers. The large number of sensors used in this massive project include rock (anchor) bolt load cells, piezometers, concrete pressure cells, shotcrete/concrete stress cells NATM style, shotcrete strain gage, embedment strain gage, multipoint borehole extensometers, measuring anchors, base load cells, inclinometer system, tape extensometer, bireflex targets (in thousands) readout units.

Rohtang Tunnel


Location: Manali, Himachal Pradesh, India
Route: Leh-Manali Highway
Length: 8.8 Km
Client: BRO

Rohtang Tunnel is a tunnel being builtunder theRohtang Pass in the eastern PirPanjal range of the Himalayas on the Leh-Manali Highway. With 8.8 km (5.5 mi) length, the tunnel will be one of the longest road tunnel in India (the longest road tunnel in India will be the Chenani-Nashri Tunnel or Patnitop tunnel north of Udhampur) and is expected to reduce the distance between Manali and Keylong by about 60 km (37.3 mi)[2] The tunnel is at 3,100 metres (10,171 ft) elevation whereas the Rohtang pass is at 3,978 metres (13,051 ft) elevation 51 km (32 mi) away from Manali.

Encardio-rite bagged the contract for supply and services of Instrumentation and Monitoring and successfully instrumented as planned. Encardio-rite joined hands with Amberg Technologies AG, Switzerland to offer the facilities of Tunnel Seismic Profile Measurement in India. Encardio-rite has successfully completed around five tests for the Rohtang Pass Highway Tunnel in India.

Austria, Brenner Base Tunnel


Location: Austria

Encardio-rite supplied instruments for the Brenner base tunnel through GEODATA. Geodata has been assigned by BBT, in association with ILF and HBI, with a participation of 40% of the contract to update the final design of the 55 km railway tunnel. Austria will spend € 1.3bn by 2016. The Brenner Base Tunnel is a nearly horizontal rail tunnel with 2 parallel tubes. The tunnel runs for 55 km between the railway stations of Innsbruck and Fortezza and is connected south of Innsbruck with the already existing underground by-pass.

This bypass and the Base Tunnel make up the world's longest underground railway, with a total length of about 64 km. Work on the 55 km twin-bore tunnel already launched from Innsbruck in the north and Fortezza in the south, with excavation of the central section between Ahrental and Trens planned to start in 2016. In March 2011, 16 km of exploratory tunnel and access tunnel had been completed.

Greece, Anthochori Tunnel


Location: Greece

Encardio-rite supplied instrumentation for the twin bore highway Anthochori Tunnel, Egnatia Highway, Section 3.2 in Northern Greece. The tunnelin followed ATM - Mechanical excavation with occasional drilling and blasting method. The project construction costs was approx. € 14,6 million. Our supply of instrumentation was through Geodata. The project was Construction during 2001-2005. The total length of tunnel is 2 x 673 m, with cross section: 105 m2.
