557 Lakhta Center Tower Overview The Lakhta Center Tower is part of an under Construction Multifunctional Complex Located in St. Petersburg, Russia, including two other Buildings, stylobate areas (underground), Arch (Tower Entrance) and a Landscape area on a site area of 13.9 Ha. The Tower figure follows a unique shape through the subsequent movements: extrusion, twisting, cone and bending. The higher the floor, smaller is the footprint. All structural and fa?ade elements follows the equivalent concept and technically custom-made to the concept. The Total Height of the Tower is 465.7 m BSL (Baltic Sea level). The Tower Building is projected to have

86 Floor Levels above ground (floor to floor height 4.20 m) and

03 Levels below ground. Within its outer limits will hold functions such as Technical Areas, Office Spaces, Dining Areas, Lobbies (including Sky Lobbies), Conference Areas and Archives. It is designed to be Green Certified (USA) Building, especially due to the energy savings. And others such as;

? Natural Ventilation at summer time;

? Trench Heaters at Winter Time;

? Maximize daylight and control solar gain;

? Maximize daylight and control solar gain;

? Reduce the mechanical intervention under both heating and cooling modes The Tower has an inner and outer fa?ade creating between them an area which is called Buffer Zone, planned to give a greater thermal performance in winter and summer time improving the comfort within Office Areas. The building will be equipped with the latest technology in terms of vertical circulation located in the central core of the tower. High speed lifts will serve the Tower in a smart way. Structurally it has a box foundation (with stiffened extra walls) seating on a massive reinforced concrete raft foundation supported by reinforced concrete piles for the substructure. Underground part of the Tower Sub-Structure form the pile box-foundation consisting of a bottom slab with the thickness of 3.6 m (Raft Foundation), a top plate with the thickness of 2.0 m (Transfer Slab), a core and
