Lakhta Center is a multifunctional complex in St. Petersburg with the Gazprom headquarter and public spaces occupying a third of the area. Construction was completed in October 2018, now start work on the arrangement of business and public areas. The opening will take place in about a year, when the complex will be fully prepared to meet guests.
Specialists Assessed Archives Data on Geological Investigations in Lakhta
According to the experts, Vendian clay which can be a solid cushion for a foundation is at the depth of up to 30m (the top layer of Verkhnekotlinskiye deposits of upper Vendian clay is detected at between -22,0m and - 30,4m BD).
According to Chief Engineer of the Investor Company Andrey Nikandrov, archives data demonstrate that the soils at the site enable to build a high-rise building by applying value engineering on foundations as compared with the project on Okhta.
At the site of Okhta promontory Vendian clay is firm layers which the foundations of a skyscraper can lie on is deposited at the depth of 60m downwards. From this point of view the site in Lakht is more beneficial. The depth of a solid Vendian clay is 30m as high. Here the skyscraper can be built on a less solid foundation, which will enable to optimize the costs for the implementation of the project.
At a subsequent stage in accordance with the valid normative documents engineering and geological investigations will be conducted to study geological structure and mechanical properties of the soils by taking into account the characteristics of a specific construction.
In the 70s of the 20th century at site a sand storage yard was designed and set up which at present occupies most of the area, road junctions, storage and productions facilities are built. Drilling works were conducted in 1965-2009.
