“A modern smoke removal system is expected to be installed in the Kakhovskaya, Varshavskaya, and Kashirskaya stations under reconstruction on the former Kakhovskaya Line, which will be part of the Big Circle Line (BCL) of the Moscow Metro”, said Deputy Mayor of Moscow on Urban Planning and Construction Andrey Bochkarev. Mosinzhproekt Engineering Holding is the managing company to construct new lines and stations of Moscow Metro.
“When renovating and constructing metro stations, we are fully committed to ensuring the safety of passengers. Half a century ago, when Kakhovskaya, Varshavskaya, and Kashirskaya stations were built, fire safety requirements were different at the metro sites. Unfortunately, they no longer meet modern requirements. As a part of the reconstruction works, the stations will be equipped with smoke removal systems, which meet all current safety standards,” noted Andrey Bochkarev.
According to the Deputy Mayor, such a large-scale reconstruction of the entire line is carried out in metropolitan metro for the first time. “Once complete, the Kakhovskaya Line will be integrated into the Big Circle Line,” reminded the head of the Moscow Construction Complex.
For his part, General Director of Mosinzhproekt JSC Yuri Kravtsov clarified that the installation of a modern smoke removal system requires work to be done to build new monolithic platforms at the stations, and then mount the smoke removal ducts under the platform area and connect them to the fans built into the columns in the platform areas of stations.
“Currently, a modern smoke removal system is fully assembled at Kakhovskaya, and a new monolithic platform with smoke removal ducts is ready at Varshavskaya,” explained the head of Mosinzhproekt.
According to the head of the holding, the replacement of the main structures in the platform area at Kashirskaya is impossible, as the station is reconstructed in the operating metro with the deboarding and boarding of the Zamoskvoretskaya Line passengers.
“Smoke removal ducts are to be mounted above the tracks of the Kashirskaya station. To do this, we will partially uncover the station structures and provide additional technical spaces in the entrance concourses of the station,” said Yuri Kravtsov.
General Director of Mosinzhproekt added that the dismantling of the old utility systems and the redesign of the existing technical spaces at all three stations were completed. At Varshavskaya and Kashirskaya, the platform areas are being cladded, preparations to install architectural lighting on the platform are underway at Kakhovskaya.
The Big Circle Line is the capital’s flagship metro construction project. The BCL will become the longest underground circle line in the world. There will be 31 stations on the Big Circle Line, 12 of which are already open for passengers.
