Bird’s nest location: N

2. Introduction: Building type – stadium Owner – Chinese government Number of floors – three but actually 20 stories of an ordinary building Height : 70 meters Wide: 296 meters Long: 320 meters Architect – Herzog & De Meuron Structural Engineer – Ove Arup & Partners Spectators - 91000 Inauguration 28.06.2008 Construction 12.2002-06.2008 Cost: $300M

3. Brief history about Herzog & de Meuron: Year of birth : 1950 both Nationality : Swiss Education : Swiss Federal Institute of Technology (ETH) in Zürich  Awards : 2001 Pritzker Prize 2009 Lubetkin Prize for the Beijing National Stadium Selected projects: 2000 Tate Modern, Bankside, London, UK 2005 Allianz Arena football stadium, Munich Beirut Terraces, Beirut, Lebanon

Project: Concept inspired by old Chinese art concept China's leading artists Ai Weiwei Sweeping lines arranged around a circular vessel. Inspired them to push the limits.

construction Jacque Herzog:"A new place compared to Paris's Eiffel tower which was made for an event but then became an icon of the city" People can go in and go out , use the space Chinese people love to use public space

Problematic ! Plan Beijing is located in an earthquake zone Olympic standards: giant screens, shops and great views of the field and of course the safety Solution ! Steel structure 15.24 m Concrete bowl

J.Parrish :"the very first step in designing a building is to look at its heart :the seating belt" each seat is going to be as close to the action as possible Distance from center to seats equals 142 m Intimacy Motivates the athletes

Steel structure 24 beams in the form of trusses encircling the concrete bowl The stadium is earthquake proof 1,000 tons each

Steel structure a second set of beams fills in the empty spaces of the beams of the first set they link all the beams to form a braided structure.

Steel structure Beijing Bird’s Nest is designed to withstand earthquakes rated at 8.0 on Richter Scale.

Steel structure a third set of beams support the stairways that connect the multiple levels and provides a frame for the roof membrane covering

Steel structure

Structure = façade = roof = space Elevation The structural elements mutually support each other and converge into a spatial grid-like formation, in which façades, stairs, bowl structure and roof are integrated.

The massive steel structure resists lateral loads The load is broken down through the lattice of steel while being weakened

The core portion of the building carries the dead load of the concrete structure as well as the live load of people totaling to 13,122 tons. Section The load is transferred directly to the plinth foundation as distributed load as shown below.

Roof The loads at each intersection are split between the members and transferred downward The red points indicate the transfer connections were load impact is felt most significantly. 

Sustainability in the project The Stadium uses geothermal energy to chill and heat the water that runs through the HVAC system the piping to do that is located beneath the main athletic field.

Sustainability in the project maximum amount of natural lighting as possible

Sustainability in the project ETFE Panels This membrane provides rain and wind protection. It also saves energy Sunshine filters through the roof to light the building keep the noise in

Conclusion  Initially I thought this stadium boasted an iconic design, and after finding out all of the technical innovations that went into it, I believe this is one of the most overall creative buildings I’ve ever seen I learned that when building systems work together in more than one way, the building itself becomes more extraordinary. From what I understand, the design idea started from ceramics and evolved into a “bird’s nest”.
