Beijing National Stadium

[Christian]

The architectural competition for the new Beijing National Stadium contains 13 proposals. The winner has been deseidet quite a while ago, but here are all 13 proposals, enjoy! Because of the size i had to present only a few images of each proposal, and i made the file size far smaller then the original once.

Beijing National Stadium proposal 1

Emerging from the landscape, and shaped by nature, the design will create a simple symbolic link - a bridge - between old and new,

between people and country and China with the world.

The design introduces an innovative solution to the provision of temporary seats during the Olympic Games. All the temporary seats

are under cover and all seats enjoy excellent views to the field of play. It adopts high technology principles for operational management

and interaction with the environment.

The moving roof created like two leaves is simple, elegant and economical. After the games, people will be able to walk, via a safe

and secure path, along over the leading edge of the roof. The extended

The design creates an image of a floating water lilly, surrounded by petals and blossoms, emerging in a gently undulating pond.

The stand installations are built for fixed as well as temporary seating with optimal viewing positions. After its dismantling, a

very unique leisure park will be developed. On the "roof" of the stands, offering a grandiose, stairs and elevators access

this panoramic sky-garden independent of the internal Stadium function.

Beijing National Stadium proposal 3

The design preserves the 45-meter height limitation with the exception of the roof structure, but the bottom rail of the tallest roof section is 99 meters from the competition pitch. The Stadium will have a total floor area of 164,000 m2, which can accommodate 100,000 spectators. The stadium bowl is partially sunken with a filigree of ramps that link the stands with the surrounding landscape to form open and clear accessibility.

The transparency of the roof petals allow for the shading of the grandstands while providing for superior natural light and weather permitting allow the stadium to be opened for natural ventilation. The roof is a series of light free flowing forms that flow over the stadium to form a series of petals that can open and close to suit a large variety of conditions. The roof is made of the Teflon coated fiberglass, which allows the natural turf to grow for a superior athletic field surface.

The structures of the petals are basic stable arch forms that are structurally efficient and have been used in manmade structures since before the classical periods. Yet the sheer spans, movement, elegance and lightness to be achieved in these arches will reflect our ever-increasing understanding of the science and technology around us.

Beijing National Stadium proposal 4

The Olympic Stadium, 79,574 fixed seats are installed on the stand, of which ordinary seats are 72,930 with 500mm width of

seats and 850mm depth of rows. If it is needed, temporary stands with 20,740 seats could be added in both the south

and the north stands. Multi-functional development operation after-event is one of the key points in the design proposals.

After Olympic Games, this Stadium will offer 11,300m2 of service room to be further developed. The height of this kind of

room is nearly 7m, the columns spacing is nearly 9m. They are all spacious room with large span offering favorable conditions

for varied operation and development in the future.

When the roof is open, the open-air area is 32,000m2. The lowest layer of the roof adopts the fixed aluminium composite

board. The upper two layers of the retractable roof adopt the efficient membrane material with high performance. Since

the membrane material is very good at deformation resistance, impact resistance, sound absorption and light transmittance,

it is helpful to economize the investment, the maintenance cost and the operation expense in the future.

Beijing National Stadium proposal 5

The 100,000-seat stadium has been conceived as a two tiered solution with exclusive areas incorporated within. All tiered seats

have an unobstructed view of athletics. Lowering the field reduces the amount of

One of the most unique features of the design is the Sky Terrace. The ability to climb to very top of the roof will provide an

experience to the visitor unlike that of any other stadium on Earth.

A concrete structure is proposed to provide an economical yet durable structure with good earthquake resistance. The

arrangement of the bowl structural grid has been chosen to allow a significant amount of repetition in the design and

construction of the stadium, and the column spacing is generally less than 9.0 m, except in the single bay where the grid

transitions from elliptical to circular. The design will utilize locally available materials and labor.

The roof structure consists of a series of trusses supported by four giant trussed-towers, which in turn support the two primary

trusses. The primary trusses consist of a compact central diamond-truss, strengthened and stiffened by high-strength cables

supported by outriggers. A number of configurations were considered, and the design refined to optimize strength and stiffness.

The cable configuration is efficient, allowing plenty of structural depth, thus limiting axial forces in the members, and utilizing high-

strength cables to minimize weight. Some of the truss cables will be priestesses to increase the effective structural depth

of the system. This configuration also allows economical construction, with the central diamond truss being prefabricated and

shipped to site, and minimal onsite assembly of components. The location of the towers is derived to balance the cantilever and

mid-span moments in the trusses, ensuring optimal use of materials, and the deflections are well within code limits.

Beijing National Stadium proposal 7

This Stadium total would comprise 80,000 permanent seats and 20,000 temporary seats, including one level of 140 suites.

The 20,000 temporary seats are removed it is proposed to install the seats in the outdoor activity center and some special suites,

restaurants, clubs and bars in the locations which are higher up in the stadium.

This technology solved the problem of being able to have a natural grass playing field turf of the highest international quality

for every soccer game, while at the same time being able to host every kind of multi-use event in the same stadium. This

requirement necessitated the complete separation of the field sports uses, from all the other kinds of uses, by having 2 separate

functional surfaces which could be changed very quickly and an infinite number of times, without deterioration of the

performing surfaces. Uses the unique Two Panel Spiral Rotating Shell Retractable Roof Geometry (United States Patent).

The roof can be opened and closed in 35 - 40 minutes in wind speeds of up to 50 Km/hr.

The sun-facing surface(s) of the retractable roof will be covered with rows of the latest type of photovoltaic cells, one of the

largest installations of its kind in the world. The proposed design will be one of the major legacies of the

Beijing National Stadium proposal 8

The configuration of the stadium symbolizes great nature on the earth. Against the backdrop of sunshiny sky, soft white

cloud and green hills are the main originality, along with light pillar that penetrates through white cloud creating nice

association. All of these constitute a charming landscape and become a new scene in Beijing tallying with the substance that

coexistence of Olympic Game and nature. In order to coordinate with the environment around the park, as much as vire scence

should be placed in the planned land.

It is such a big stadium that can hold 100 thousand people at the same time. Moreover, 100 thousand people can enter and exit

at the same time. The auditorium is composed of three layers, which have 100 thousand seats, including 80,156 fixed seats

(800mm*500mm) and 20,644 temporary seats (800mm*495mm). We define

Beijing National Stadium proposal 9

The National Stadium should be the one that a surrounding feeling is available when someone stays inside of the stadium, he feels that he is surrounded by the environment outside of the stadium. Vice versa, when he stays outside of the stadium he could also feel such a state of competition with excitement and vigor inside of the stadium. Thus, a well arranged space functioning from each other is created.

The adoption of different resources of energy will secure the natural light collection and the air ventilation as well as a reliable and efficient method for the site management.

The ecological tower with the total height of 200m, is the key point or the pith of the presentation for the principles set up for the design work of the stadium. The four groups of windmill erected on the tower could generate enough power for the use of the tower itself and environmental lighting around.

The roof the gymnasium consists of four parts, namely, top floor roofing, mobile roofing, lower floor roofing both on West and South sides and the North side roofing. The mobile roofing covers the whole gymnasium and is supported by using a rail system with 18m.vertical and horizontal tri-framework. When it is in the closing state, the whole gymnasium is covered, vice versa, the roofing goes over the lower roofing on the North side and is hanged outside.

Beijing National Stadium proposal 10

This proposal is intended to meet these objectives using the symbols of "Heaven" and "Earth". Our roof is not just a cover for the terraces of the stadium, but the celestial vault of the Universe. This vault incorporates five circles that, at the same time, symbolise the five elements on which Chinese philosophy is based, and the five Olympic rings.

The roof of the stadium, 665 m long at its longest dimension, this lightweight, elevated fixed roof is suspended from a structure of 18 steel columns by cables imitating the latest techniques of cable-stayed suspension bridges.

The retractable, translucent material used for the roof covering will filter the natural daylight by around 50%, thus allowing, when used during the day, sufficient natural light to enter the stadium, minimising the need for artificial light.

The two glazed roofs, where they cross, will add to this effect. Of a reasonable size and simple to operate, the retractable roof will not squander resources or energy as it is opened and closed. The exceptional area of the roof will be equipped with solar panels, which will provide it with a substantial proportion of the energy it needs.

Beijing National Stadium proposal 11

The design concept is retrieved from an ancient ritual named "throwing jade into the water", which gives the Stadium rich cultural

connotation and turns the place into a spiritual home of people living in a modern city. The National Stadium will be designed to

put athletes above everything else. In the general layout, warm-up areas for athletes are arranged on the north side of the plot

area, close to the rooms provided for them inside the National Stadium, which will provide a shorter way for athletes and facilitate

their competition.

To meet the multifunctional operation requirements of the National Stadium, some comprehensive development facilities are to be

arranged appropriately on the perimeter of the main building. This will enable complementation of functions between the existing

facilities inside the National Stadium and those to be provided on the perimeter, and provide a variety of options for the

long-term operation of the National Stadium while avoiding possible waste. Reasonable division of ground and underground levels

will enable effective separation of people from vehicles on the perimeter of the National Stadium, to ensure smooth access for

various categories of people without interference with each other.

The Stadium is creatively designed to have a worldwide unique "suspending retractable roof" combining multiple functions of roof,

sightseeing and urban landscape. The arrangement of appropriate operating spaces outside the Stadium will represent additional

functions and new concept of sports building operations.

Beijing National Stadium proposal 12

The Stadium is the Architecture as the eaves, and it protects as many as a hundred thousand people in the periphery from the

rains, cold wind of winter, and hot sunshine of summer. The Stadium is the symbol of the attitude greeting all the people. The

Architecture succeeds the sense of the Quadrangle cosmology. It opens the earth to the universe, and harmonizes the pure form

with the dynamic action of the wings. The wings of the roof, corresponding to four blocks of the stadium, lead up to various modes.

During the Olympics, temporary seats are installed on the wings. At ordinary time, the wings function to stabilize the climate of the

field. When the wings are open, they leave no rails or structures behind the space they occupied.

The light roof and ceiling, having the span of 180m, are made of film materials with aluminum alloy. controlled by air pressure. The

ceiling is constituted of the tubes with two functions. As to the lightning and diffusion, it changes freely as the clouds.

Construction period: 2004 - 2008

Architect 1: Chinese Architecture and Design Research Group

Architect 2: Herzog & de Meuron

Project in general

This is the future Beijing National Stadium and was approved by the city council. The stadium will room as much as 100 000

seats during the olympics in 2008, but will be reduced to 80 000 after the games. The stadium is 330m long by 220m wide and

69.2m tall. The 250 000sqm (groos floor area) stadium is designed with 36km of of unwrapped steel, and got a weight on 45 000

tonn. The stadium will cost as much as 3.5 billion yuan (422 873 850 USD/ 325 395 593 EUR/ 2 721 437 889 NOK). Because of

this cost the has been suspended. The ground was broken in december 2003, and construction started in march 2004, but is now

on hold.

In the new design, which has not yet been relised, the roof of the stadium is supose to be erased from the design. Experts say

this would make the stadium safer and it will reduce the construction costs. The construction of the olympic buildings will step

up again in the beginning to 2005 again, and hopefully continue its construction without any delay before its completed.

Olympic building busy during Spring Festival

Chinadaily.com.cn - Beijing

The pace of construction for the 2008 Beijing Olympics has stepped up, with some key projects now running round the clock during the traditional Spring Festival.

Other Olympic venues will also step up construction.

The pace of construction for the 2008 Beijing Olympics has stepped up, with some key projects now running round the clock during the traditional Spring Festival.

The transfer buildings for all international flights during the Olympics will be largely complete by June and workers are busy building roads and a transportation hub at the airport.

The Beijing subway lines 4 and 10 will have their main routes finished by July.

Other Olympic venues, like the main national stadium and the national swimming centre, will also step up construction this year.

[monsoon]

Those are amazing renderings. Unfortunately of all the ones presented, I liked 13 the least.

[satalac]

that first one kinda looks like a giant vagina. i expect to hear many jokes about that during the olympics. those are really cool buildings though.

[bret15]

Fantastic Views and renderings! but only one can be built, so I think you should start a poll for the best proposal!

<{POST_SNAPBACK}>

Yes i should have, but i can't include a poll now, because i can't edit the thread my self. And as you can see i have a huge problem with photobucket, because i have exceeded the bandwidth of this month, so i need to wait one month till the images can be viewed public.

But its always possible to copy the images adress and open it to view it.

What's going on in proposal #11, is it hovering, I can't see any supports or wires?

[Christian]

What's going on in proposal #11, is it hovering, I can't see any supports or wires?

Thats because its flying!

That thing is the roof of the stadium, and they can make it fly when they pump it full with helium. IN that way they can lift the roof of the stadium without great machines.

Construction update:

Final design of the stadium is the one on that rendering.

[cheeriokid61]

I like numbers 2,5,8, and 11, especially #11 with the floating roof. What a cool idea!

[rbdetsport]

Proposal 13 is ugly. I like proposal 2. It is very unique, but not to much.

[Mith242]

I liked 5, 9 and 13. I think the finished stadium will look better than some of those renderings.

[johnnydr87]

I must echo monsoon's and satalac's comments. Those were my two main thoughts.

[Spartan]

#6 is my favorite. It looks like a modern version of traditional architecture.
