布里斯班为2032年奥运会规划中将临时基础设施作为核心策略，以避免赛后遗留大量闲置场馆。[1]这一被称为"overlay"的方案包括在机场、车站、街道和粉丝区等现有场地上增加临时性改造，涵盖安全检查区、广播设施、招待区、商品店、运输设施、现场直播地点、临时看台和人群管理基础设施等要素。[1]
Populous建筑事务所的建筑师James Pearce解释，这种设计允许城市在奥运结束后避免留下庞大的永久性设施，同时将整个城市作为奥运体验的一部分。[1]Pearce表示："overlay是一个很好的方式，能够为这种百年一遇的机会提供所有额外的可能性，同时允许场地在事件结束后以更适当的模式继续运营。"[1]
这一策略参考了历届奥运会的经验。[1]悉尼2000年奥运会的临时座位曾容纳了115,000人，赛后被移除；伦敦2012年奥运会期间，奥运体育场周围的桥梁也被临时加宽以应对奥运期间的人流和安全需求。[1]根据规划，部分安装需要数周建造，而包括完全临时体育场馆的项目则可能需要数月建造和数月拆除。[1]
Brisbane's organizers for the 2032 Olympic Games are employing a strategic approach centered on temporary infrastructure, known as "overlay," to avoid leaving behind costly unused facilities after the event concludes.[1] The overlay concept involves adding temporary structures and modifications to existing venues and public spaces, including security screening areas, broadcasting facilities, hospitality zones, merchandise stores, transportation infrastructure, live broadcast sites, temporary seating, and crowd management systems.[1]
This planning philosophy draws lessons from previous Olympic Games. The 2000 Sydney Olympics demonstrated the value of removable installations, with temporary seating at Olympic Stadium accommodating 115,000 spectators that were dismantled after the Games.[1] Similarly, London 2012 implemented temporary bridge widening around the Olympic Stadium to manage Olympic traffic and security requirements.[1] According to architect James Pearce, the overlay approach enables the city to transform into a comprehensive Olympic experience while ensuring that venues revert to appropriate post-Games operations.[1] "Overlay is a great way to provide all the extra possibilities for this once-in-a-century opportunity while allowing the venues to continue operating in a more appropriate mode after the event ends," Pearce stated.[1]
The construction and removal timelines for these temporary installations vary considerably.[1] Some installations require only weeks to build, while others, such as fully temporary sporting venues, may demand several months for both construction and dismantling.[1]
