NBBJ | 杭州奥林匹克体育场

如同中国许多城市一样，杭州正经历快速的城市变革。当围绕西湖地区的城市中心历史上曾被多次开发后，该城市的工业和商业机遇使城市扩张至钱塘江畔。

NBBJ与CCDI合作在杭州新中心商务区钱塘江对岸基地上设计了400,000平方米的杭州奥林匹克体育场（包括80,000座位主场馆、10,000座位网球中心、游泳馆、会展中心、运动设施和地下商业）。

激活场地活力

场地平面由三层活动构成：地上平台定义了“体育大道”，它将主体育馆和网球公开赛等设施连接起来。首层、小径、花园和广场构成了公共休闲活动网络，专为另类和极限运动而设计。下沉式空间和庭院通往大型地下商场，商场由精品商店、餐厅和多功能电影院组成。

整合的计算机辅助设计

随着全球钢材需求的增长—仅在过去十年增长了78％，其成本也是如此，自2007年以来已飙升了217％。因此，NBBJ使用参数化设计来减少浪费，同时创造建筑功能和形式。

设计师采用了先进的参数化程序和模型技术来开发和优化建筑外壳。几何规则和其他性能驱动因素被用于把概念意图与图纸和施工的流程联系起来。由于模型是参数化的，设计变更可以在极短的周转时间内完成并消除了传统建模中的常见的“建筑-测试-摈弃”的方法。

工程师和材料顾问运用参数模型作为跨学科合作的基础，工程师和顾问可以直接运用设计团队的成果来执行其专项设计和分析操作。专业间的紧密沟通使设计团队确保质量控制并同时发现更多优化机遇。

最终的成果？与著名的北京国家体育场鸟巢等类似竞技场相比，节省了67％的钢材。

Like many cities in China, Hangzhou is undergoing rapid urban change. While the city center historically developed around the West Lake area, opportunities for industry and commerce have shifted the city’s expansion towards the Qian Tang riverfront. New construction has tripled the city’s size in the past decade,creating a modern architectural fabric that is powerful in scale, yet still in need of public space.

NBBJ,in partnership with CCDI, designed the Hangzhou Sports Park (including 80,000-seatmain stadium, 10,000-seat tennis center, aquatic center, convention center,athletic facilities, below-grade retail) on a 400,000-square-meter site on the Qian Tang riverfront opposite the city’s new Central Business District.

Activating the Site

The site plan is composed of three layers of activity. An above-grade platform defines the “sports boulevard,” which links programs such as the main stadiumand tennis tournament facilities together. On the ground level, pathways,gardens and plazas form a network of public recreation activities designed for alternative and extreme sports. Sunken spaces and courtyards lead to anextensive below-grade retail pavilion containing boutique stores, restaurantsand a multiplex cinema.

Integrated Computational Design

As worldwide demand for steel increases — by 78% in the last decade alone — so does the cost, which has skyrocketed 217% since 2007. That’s why we use parametric design to cut waste while creating functionality and form.

Our designers leveraged advanced parametric scripts and modeling techniques to develop and optimize the exterior shell of the Hangzhou stadium. The steel shell and concrete bowl systems were coordinated and linked for stability and optimized steel use. Because the model was parametric, design changes could be made with an extremely short turnaround, eliminating the “build-test-discard”method common in traditional modeling.

The parametric model was used as the basis for cross-disciplinary collaboration with engineers and material consultants. The engineers and consultants coulduse the design team’s output directly for performing their specialized designand analysis operations. The close communication between disciplines enabled the design team to ensure quality control and also find opportunities for further optimization.

The end result? We achieved a 67% steel savings over similar arenas like the famed Bird’s Nest, the Beijing National Stadium.
