DESCRIPTION |

|
|
 The tent-like, cable-net structure is located at the northern end of the new city axis and soars 150 metres from an elliptical base to form the highest peak on the Astana skyline.
The building encloses an area in excess of 100,000 square metres within an ETFE dome, with dramatic views over the city and the Steppes beyond. Contained within it is an urban-scaled park, along with a wide variety of entertainment and leisure facilities, including retail, cafes, restaurants, cinemas, and flexible spaces that can accommodate a varied programme of events and exhibitions. The different levels form undulating terraces, the uppermost terrace forming a water park. |

steel, ETFE  60m Tripod leg weighs 351 tonnes.
Each 70m Tripod leg weighs 211.5 tonnes.
The ETFE and cable roof is very lightweight and thus efficient- the large spans would make for a very heavy structure if it was steel and glass- and by hanging the roof from the tripod all the cables are simply in tension, which is a very efficient system for steel.
Because of the cable net's nature as a tension structure the entire roof is designed to move as wind and snow loads are imposed - the whole structure will thus move - but in fairly small amounts.
12,300 driven piles and 94 bored piles under the foundation.
Total Weight (Tripod + Hub + Struts + Top Ring + Basket + Top Mast) + (Cables + Cable Supports & Anchorages) (1.600 tons ) + (404 tons 392 tons) = (1.600 tons) + (796 tons) = 2.396 tons
Reinforced + Lean/Screed Concrete=174.000 m³ ~ 431.800 tons.

ECO-SUSTAINABILITY |

|
 Temperatures in Astana can drop to -35 degrees Celsius in winter and climb as high as +35 degrees in summer. The three-layer ETFE envelope is designed to shelter the enclosed accommodation from weather extremes and to allow daylight to wash the interiors. In winter, a key challenge is to prevent the formation of ice on the inside of the envelope.
This is achieved by a combination of temperature control and directing warm air currents up the inner surface of the fabric, a strategy that also prevents downdraughts. In summer, fritting on the outermost foil layer provides solar shading. Inside, low-level jets direct cool air across the space, while opening vents at the apex induce stack-effect ventilation. |
