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. »

Lakhta Center bearing foundation structure registered achieves Guinness World Records title

On March 27, 2015 GUINNESS WORLD RECORDS adjudicator handed over a certificate for a new GUINNESS WORLD RECORDS title for largest continuous concrete pour to the directors of Lakhta Center, the company dealing with the project.   

The GUINNESS WORLD RECORDS title was established during the pouring of the lower slab of the foundation of Lakhta Center Tower which lasted from 8pm February 27 until 9pm March 1, 2015. 19,624.0 m³ (25,667.22 yd³) concrete mix was laid in the foundation within 49 hour continuous concreting, which exceeds the existing GUINNESS WORLD RECORDS title at over three thousand cubic meters.

Previous established records:

  • 16,208.6 m³   Wilshire Grand Center (USA) in Los Angeles, February 15-16, 2014; 
  • 14,000.0 m³   “Vostok” Tower, Federation Complex in Moscow, February 21-24, 2006.

Lakhta Center Executive Director Alexander Bobkov: «By 2018 we will have completed the construction of not only the tallest building in Europe but the construction of a complex which will meet the highest requirements in relation to reliability and operability for the decades ahead.  The GUINNESS WORLD RECORDS title was successfully completed and was preceded by months of calculations and tests, development of logistics schemes and control systems. As a result the unprecedented operation was completed without any delays or overlaps.  The main bearing structure of the skyscraper is gaining strength and preparing to take loading from the overground floors which will be built as early as this year”.

 

Reliable Foundation for the Tower

The height of 462 meters and weight of 670,000 tons dictate specific requirements for the foundation of the building. The box shaped foundation rests on 264 piles with a diameter of 2 m and a length of 65 m, buried 85 meters deep in the ground. It consists of two heavy structures: the top slab with a height of 2 m, and 3.6m bottom slab, exceeding standard floor height. Structure rigidity is ensured by a central core, additional overlapping slab and traverses (stiffening diaphragms).

The most robust structure of a high-rise building foundation, and the one most difficult to manufacture is the bottom slab. It has the shape of an equilateral pentagon with area of ​​5,670 square meters.

Unparalleled strength of the plate is ensured by 15 levels of reinforcement grids made of 32 mm steel reinforcing  bars. It took 9.2 thousand tons of metal, supplied from rolling mills all over Russia, just to reinforce the bottom slab foundation of the Lakhta Center tower. For comparison, roughly the same amount was used for the construction of the Eiffel Tower.

Project engineers will monitor quality, tension and deformations of foundation during further construction and operation of the building. For this purpose, 330 sensors have been installed in slab body to provide accurate measurements.

 

Lakhta Center is a multifunctional public and business complex, with headquarters of Gazprom Group as its core. In addition to offices, the new complex will house children's scientific and educational exploratorium "World of Science", exhibition spaces, planetarium, medical center, multipurpose hall for meetings, conferences, theatrical, music and other performances, as well as cinema center, sports center and a number of public services, including bank office, shops, restaurants, cafes etc.. The total area of buildings and structures will be 400,000 m2. Construction of the complex is scheduled to be completed by 2018.

Currently, foundation work continues: foundation of the multifunctional building (the one adjacent to the tower), diaphragm wall along the foundation perimeter and pile foundation of the tower have been completed. Box foundation is being installed, serving as a base for the high-rise building.
