The construction of a metro brings many concerns into action. Since the metro runs from various areas, it is crucial to judge, monitor, and provide remedies for the effective construction of long metro tracks. This is where geotechnical monitoring and instrumentation come into play. It helps to mitigate the risk to life and property while keeping the surroundings safe.
The establishment of the metro not only solves the problem of traffic and pollution but also promotes integrated development among different regions. Metros are celebrated by the residents, as it greatly helps to reduce the distance across the city. Being pulled closer with the help of advanced technology, it is only fair to do it correctly.
Since most of the metros run through underground tunnels, it becomes important to monitor them. While constructing tunnels, geotechnical monitoring is of utmost importance. It assists in assuring the stability and strength of the tunnel, certifying the design, and assessing the intensity and sequence of the operations involved during construction.
Encardio Rite, a leading geotechnical and instrumentation company, was associated with the construction phase of the prestigious Doha Metro and provided its robust instruments and monitoring services. Let’s have a look at how it was done.
The Doha Metro is a key project of the Qatar National Vision of 2030. Situated in the capital city of Qatar, the Doha metro has three lines with an approximate length of 76km serving 37 stations. A part of the larger Qatar Rail Network, it is expected to expand, linking Qatar to the GCC, and the Lusail LRT. The Red, Gold, and Green lines has become operational in 2019, while the larger plan of an additional line (Blue) and the expansion of the existing ones, with more than 60 stations are expected to complete by 2026.
Owing to Encardio Rite’s proven track record in managing the monitoring of esteemed metro projects globally and providing quality and diversity of technologies, it was offered a contract for all 4 packages. These included Major stations – Msheireb and Education City, Gold Line – 13.50 km, Green Line – 16.60 km, Red Line South – 12.05 km, and Red Line North – 11.30 km.
It was entrusted with instrumentation & monitoring of the project along with pre/post-construction condition survey of structures and supply and installation of geotechnical instruments.
Encardio Rite provided the following turnkey solution for each of the Doha Metro lines.
Other instruments included building settlement points, road prism targets, and vibration monitoring devices. Apart from this, online monitoring was done using automatic data loggers and data acquisition systems for geotechnical sensors that were critical. Monitored data was also made available online through Encardio Rite’s web-based data management system.
The Doha Metro's first phase is successfully operational now. Learn more about Encardio Rite’s projects here.
