Big Circle Line
Moscow Metro Development Program has no world analogues. Expansion program impresses by its scale that involves the maximum extent possible resources. The Group of Companies Mosproekt-3 engineers joined the unprecedented metro construction program when it had just been launched, and in the shortest time possible improved professional competencies in the field of underground space development.
The Group specialists continue introduce advanced technology and develop technology-based effective solutions. Today The Group of Companies Mosproekt-3 engineers implement the Big Circle Line sections. When complete, it will be the world’s longest circle line.
The construction of the Big Circle Line southern section was carried out under difficult geological conditions complicated by the lack of space and dense urban development. Because of aqueous soil in a project area, during the construction there were developed some additional design solutions to exclude the possibility of water infiltration. Many technical and architectural solutions were effectively implemented due to the use of BIM-based 3D-modelling programs, which are being successfully introduced into the company activities. At all stations there were implemented the most recent transport safety systems: a new tunnel monitoring system and CCTV system with biometric facial analysis software.
The stations of the Big Circle Line southern section are located at the existing dense urban development area, so we had to remove lots of utilities and consider the impact on nearby engineering networks and buildings. Furthermore, we had to develop documentation to integrate the facility with the existing structures of Moscow Metro. On this purpose, we’ve checked Moscow Metro archives and explored the existing structures. For the linking sections we developed documentation required for the implementation of the measures that take into account passenger traffic during the construction period by excluding operating sections and were designed specially to neutralize the impact on the operating stations.
