Doha Metro Project

The Gold Line Metro Project is part of the Qatar Integrated Rail Project which is a key infrastructure project of Qatar National Vision 2030. Doha Metro is set to become the most advanced rail transit system in the world.

The east-west Gold (Historic) Line is the largest line of the project and extends from Ras Bu Aboud in the east, crosses Msheireb Major Station and reaches Sport City in the west (near Aspire Zone). It consists of twin tunnels of approximate length of 16 km, with ten underground stations. Six TBMs were deployed to carry out ~ 32 km of tunneling at an average depth of 20 m below ground. 24
no. cross passages and one Emergency Exit have also been constructed in the project.

Problem

The challenge was to ensure that the construction and excavation work proceed safely with monitoring of ground settlements and deformations, groundwater/dewatering, shoring/piling works and of the structures within the zone of influence of deep excavations and TBM/NATM tunnel alignments during the construction period.

Solution offered

Encardio-rite was entrusted with the complete monitoring work of the project including supply, installation, monitoring & surveying of geotechnical, groundwater and geodetic instruments. It also included daily & weekly reporting with evaluation & interpretations, maintenance & calibration of instrumentation, and processing & uploading surveying data to the database.
 
Six TBMs were deployed to carry out almost 32 km of tunneling at an average depth of 20 m below ground. 24 no. cross passages and one Emergency Exit were also constructed for the project.

Encardio-rite instrumentation scheme included surface settlement point, inclinometer, automatic water level recorders and vibrating wire piezometers, standpipe piezometer, crack meter, load cells, multi-point borehole extensometers, pressure cells & strain gages, and tiltmeters.
