摘　　要：介绍了一项令人叹为观止的工程——人造低温干燥和低温潮湿的生态建筑.这项非同寻常的钢结构工程在新加坡国际化发展进程中占据了举足轻重的地位,其工程规模、设计难度和建造工法在新加坡现代建筑历程中独树一帜.在拥挤的城市中心实施这项复杂的工程,需要设计师和建造师分别借助先进的结构分析软件及BIM技术,开展可视化建造、装配和项目进程预演.由于超常规的外形、跨度和高度,增加了该项工程的装配与建造难度,需要竭尽全力去预见问题,并为构件运输和施工安全设计可行的节点大样.鉴于全球性的气候变化,该项目也探索了可行的降排二氧化碳的绿色建筑技术,从而减小对生态的影响,同时,实施了节能与节水技术,以期对建筑环境的干扰最小化.综上所述,钢是轻质、大跨度与超常规建筑结构的优先选择.This paper presents the design and construction a spectacular structure--Cool-dry and Cool-moist Biomes at the Garden by the bay in Singapore. This unusual steel structure is perceived to have significant impact in transforming Singapore to become a global city. Its complexity in terms of size, design and craftsmanship was without equal in the recent history of Singapore. The execution of this complex structures in a densely build-up urban environment required close collaboration between the designer and the builder using advanced analysis software and BIM for pre-construction visualization, fabrication and project execution. This structure was difficult to fabricate and constructed because of its unusual shape, span and height. Special efforts were needed to identify problems earlier and to design practical joint details for transportation and safe construction. Aware of global issues pertaining to climate change, this project also explores sustainable and green technology with an aim to lower carbon emissions and reduce their impact on biodiversity, operation energy and water usage and thus minimize its impact to the built environment. It concludes that steel is the preferred choice for lightweight, long span and unusual shape construction.
