BIG CIRCLE LINE SOUTHERN SECTION IS ABOUT TO BE COMPLETED BY THE END OF A YEAR

The Big Circle Line southern section is more than 60% complete. The project was designed by Mospromproekt JSC, which is a member of The Group of Companies Mosproekt-3.

“Despite cold winter and extreme weather conditions, we don’t stop metro construction. This year we are going to open three sections: western, south-western and southern section, which means 11 stations in total. The southern section is almost complete”, – said Sergey Sobyanin, Mayor of Moscow, during the Vorontsovskaya Station site visit.

Today all three stations of the future section are under construction.

“Tunneling on the sections from Prospekt Vernandskogo to Vorontsovskaya Station and from Zyuzino to Kahovskaya Station is over; the right main line tunnel from Zyuzino to Vorontsovskaya Station is also complete. Natalia tunneling shield will complete the left main line tunnel between those two stations in April”, – said Andrey Bochkarev, the Deputy Mayor of Moscow for Urban Planning and Construction.

The Group of Companies Mosproekt-3 engineers managed to link the Big Circle Line station under construction with an operating station of the Kaluzhsko-Rizhaskaya Line and avoid closure of the Kaluzhskaya Station northern hall. Removed stairs that lead to metro station trough pedestrian crossing under Profsoyuznaya Street will be reconstruct within new station hall of the Big Circle Line.

For new station hall structures, the Group engineers developed nonstandard design solution, which is quite unique for Moscow Metro. 

“New station hall under construction is located at the tunneling shields output area. Our team considered temporary apertures, so we could construct main structures without waiting the end of tunneling. Through those apertures, it can be produced removal of the tunnel boring machine after tunneling work is over. This method allow to significantly shorten the construction period”, – explained Anna Merkulova, The Group of Companies Mosproekt-3 CEO.
