IN-SITU CONCRETING IS BEING COMPLETED AT FIVE STATIONS ON THE TROITSKAYA METRO LINE

“The installation of cast-in-situ structures of the stations on the Troitskaya metro line on the section from Novatorskaya to Mamyri is 90% complete”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.

Mosinzhproekt Group of Companies is the operator of the Moscow Metro Development Programme.

“The Troitskaya metro line continues to be actively constructed. In-situ concreting activities are nearly complete at its five stations: Novatorskaya, Universitet Druzhby Narodov, Generala Tyuleneva, Tyutchevskaya and Mamyri. The specialists have started interior design work”, informed Andrey Bochkarev.

According to him, the concourses of the prospective stations are also in a high degree of readiness, and work continues.

Igor Voystratenko, Chairman of the Moscow State Construction Supervision Committee, specified that an on-site inspection had been carried out to verify the construction of four stations from Novatorskaya to Tyutchevskaya.

The experts of the Moscow State Construction Supervision Committee assessed the site organisation, and compliance with the health and safety requirements. The involved staff of the Centre for Expertise, Research and Testing in Construction (SBI CEIIS) carried out a comprehensive analysis of the facilities. In particular, cast-in-situ and precast structures were inspected: the grade of concrete and reinforcing steel was checked, and the quality of brickwork was tested on the compliance with technical regulations and project documentation.

“On the instructions of Sergei Sobyanin, Mayor of Moscow, the Committee pays special attention to the quality of the construction of the metro facilities. According to the results of the examinations, if any violations are found, the inspectors will take control of them until all the remarks are completely eliminated”, said Igor Voystratenko.
In his turn, Yuri Kravtsov, General Director of Mosinzhproekt JSC, specified that tunnelling between all stations of the section from Novatorskaya towards Kommunarka had been completed and work was underway to fit them out.

“The rigid base of the tunnels is about three quarters complete at the section, the track superstructure is over 50% complete”, said Yuri Kravtsov.

The Troitskaya line, which is about 40 km long, will link the platforms of the Moscow Central Circle (MCC) with the urban district of Troitsk, passing through the South, Southwest, Troitskiy and Novomoskovskiy Districts of Moscow. About 1 million people live near the new stations, and several hundred thousand more work or study nearby.
