Spire Weighing More Than 2,000 Tonnes Starts to Be Installed on the Lakhta Center Tower in St. Petersburg
"The construction workers started installing a Tower spire at the level of the 83rd floor of the Lakhta Center Social and Business Complex in St. Petersburg", the project press service informed via social media.
According to the press service, the Lakhta Center Tower spire will contain the utility systems important for the building. The spire will become a base station for the building maintenance unit - a kind of lifting train that will move along the rails laid on the edges of the Tower. This train will facilitate washing or replacement of glasses in any place of the skyscraper.
"Moreover, inside the spire there will be equipment installed to maintain the highest levels of the Lakhta Center and, as in all super high buildings, communication and navigation systems, which can result in multiple increase in its performance due to the height of its location," the message reported.
The Lakhta Center spire is a sharp-pointed pentahedral pyramid located around and above the central reinforced concrete core of the Tower. It relies on the floor slab of the 83rd floor at a height of 344 m. The height of the spire is 117.75 m, and the total weight of the spire steel structures is over 2,000 tonnes.
However, the spire of the skyscraper will have no glazing similar to that which the other parts of the building have. Its walls will be represented by a fine steel mesh due to the particular features of the St. Petersburg's climate.
"For the spire of the Lakhta Center, icing is one of the major problems. The calculated averaged ice load can reach 50 kg per square metre on the spire's edges. The solution to the Lakhta Center's problem was to replace glass for mesh, which, firstly, has reduced ice crust surface area and, secondly, made it possible for the spire to be ventilated. Moreover, a proper combination of mesh pattern and colour makes it possible to create a visual unity of the spire and the glass facades located below", the press service adds.
Lakhta Center is a multifunctional social and business complex, the central part of which will be formed by the headquarters of Gazprom Group and Gazprom Neft Company. In addition to the offices, the new complex will accommodate a child research and education centre, a planetarium, health and sport centres, a multifunctional transformable hall for congresses, conferences, stage and musical performances as well as an open amphitheatre for 2,000 seats, a bank, a cafe and restaurants.
The construction is under way since October 2012. The height of the Tower will be 462 m. It is scheduled that the construction of Lakhta Center will be completed in 2018.
