Hangzhou Olympic Center
Competitions Undertaken:19th Asian Olympic Games 2016
Project Location:Hangzhou, Zhejiang Province
Building Height:Main stadium: 59.4m
Building Storey:Main stadium: six stories aboveground and one story underground
Seating Amount:Main stadium: 80,000 seats
Client:Partner of Hangzhou Olympic Sports Center Construction Investment Co., Ltd.:
Product Category:Sports building and digital engineering
Specialty Involved:Planning, building, structure, M&E, budget estimate, landscape, interior, BIM and sports technology
The consortium of CCDI and NBBJ, as the overall design leader and coordinator of the project, has completed the overall conceptual design of the project, helped the client further establish the functional orientation, plane layout, traffic organization and so forth of Hangzhou Olympic Sports Center, and undertaken the architectural design of the main stadium, tennis center, ancillary commerce and underground garage. To be specific, the 80,000-seat main stadium, after being built up, will become the second largest stadium in China, ranking behind the National Stadium “Bird's Nest”; the 10,000-seat tennis finals court adopts a retractable roof, and can thus ensure all-weather and multi-functional service.
Planning and design
• “Organic”, a relatively general concept, is embodied as a flow line pattern in form in the specific design of the project and as an interactive relation among various forms in space.
• The concept of “water” describes the main natural characteristics of Hangzhou, a city embraced by waters and hills.
• The concept of “green” is concretely manifested in the relation between the building and the earth, and emphasizes the idea of a building growing naturally out of the earth through weakening the hard boundary between them; many green gentle slopes have been designed as buffer zones to create a gradual psychological acceptance process for people approaching it.
• Full consideration of the temporal pattern of the venue and its nature as a complex integrated with sports industry, commerce, convention & exhibition, MTR properties and so forth in the architectural conceptual scheme
• Hangzhou Mass Culture Center, Seal Museum of China and other mass participation cultural formats are introduced to enrich the cultural formats and lay the foundation of atmosphere creation for operations in the late stage.
• Underground and large-size commercial streets are integrated to fully explore the commercial potentials besides sports events, and to further improve its operational capacity.
• Integration of structure, surface and outer envelope systems to achieve the high unification of safety, economic efficiency and aesthetic appearance
• Design of the radial primary truss with a cantilever length of 52.5m and an underground overall structural length of 700m, and adoption of a super-long and seamless structural system, posing new challenges to both design and construction
• Introduction of structural innovations to create rich visual impacts, drive construction technology improvement and embrace the challenges of complex building construction
• Further reduced emission of greenhouse gases by the power-saving lighting system
• Metal roof + PC sheet, characterized by long service life, high self-cleaning performance and recovery convenience, exerting only an insignificant impact on the environment in its full life circle
• Adoption of rainwater collection technology to fully utilize recycled water
Curtain wall design
• Use of perforated plates on the façade, creating light and transparent patterns varying with day and night and meeting the special fire control requirement on the outer facade
• Use of PC sheet as the transparent material, characterized by high transparency, high safety, high reliability and water-proof performance, less secondary structures, light weight, etc.
• Adoption of vertically transparent and horizontally nontransparent glass curtain wall; use of super-white tempered glass; use of aluminum alloy grid ceiling and diamond pattern layout; alternate layout of stone curtain wall and stainless steel plates on the lower square
• Accurate layout of minor keels based on the rhinoceros model, and accurate marking of the construction positioning point of each keel
• Functional partition
Green leisure river bank, ecological leisure river bank, four characteristic landscape gardens and river bank leisure area
Urban portal square, urban leisure square, urban entry square and commercial leisure square
• River bank pedestrian systems
River bank pedestrian systems consist of three types, i.e., aerobic exercises-oriented green channels, riverside walkways, and access passages connected with the exits/entrances of the building.
• Touring routes
Touring routes are divided into ground-level and 8m platform-level touring routes. The podium level provides the primary touring route, while the ground level provides the riverside park touring route. After entering the park through the main ground/platform entrance, tourists can freely change routes between the two via the vertical transportation connecting the ground and the platform; the landscape elevators and ground slopes distributed on site can help tourists realize barrier-free sightseeing in the entire park.
• Coastline form
The east and west river courses of Qijia River are the main channels for internal shipping, and they connect the broad east and west sides of the river, creating a gentle yet vast coastline
• Shipping system
A pier terminal for the berthing and repair of internal ships is built on the north side of Qijia Gate; four public piers are built in the principle of proximity to the stadium beside the river courses, creating a smooth and concise internal shipping system.
• Staged and partitioned construction
Guided by the goal of the unification of landscape project implementation in the future, the project is divided into three stages based on landscape types and regional independence, i.e., stage I river course & river bank area, stage II stadium area and stage III tower area.
• Respect for buildings: use of lighting to deliver the theme and connotations conveyed by the building to people at night, instead of purely showing the light or the lamps and lanterns; design of lighting in such a way as to accurately understand the ideas conveyed by the architect and to correctly grasp the theme and characteristics of the building
• People-oriented approach: embodiment of respect for people from beginning to end in lighting design; lighting layout based on multi-view visual line analysis, thus both effectively ensuring the lighting effect and strictly controlling glare
• Green lighting: saving of lighting power under the premise of guaranteeing a sufficient scale and quality of lighting; attaching of importance to energy saving and environmental protection in overall design; consideration of the power consumption by different lighting scenarios to rationally balance the division of lighting layers of different scenario modes
• Safety and practicality: Full consideration of the installation methods of lamps and lanterns in the design process, making convenience for installation and future maintenance; adoption of low-voltage products for lamps and lanterns within an approachable scale, and keeping of the working temperature below 65° for lamps and lanterns within the reach of arms; avoiding of personal injuries caused by the high working temperature of lamps and lanterns
