Specialists Assessed Archives Data on Geological Investigations in Lakhta

21.04.2011

As requested by Social and Business Center Okhta CJSC the Department for Engineering Geology, Trest geodezitcheskikh I inzhenernikh rabot OJSC (Trest GRII) assessed the reports of the engineering and geological investigations conducted in different years at the site of the planned construction of a new public and business complex in Primorsky district at the address: 2/3 Lakhtinsky avenue, Lit. A.

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.

Note
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.
