芝加哥螺旋塔是美国芝加哥的知名摩天大楼项目。该建筑由西班牙建筑师圣地亚哥·卡拉特拉瓦设计，由Shelbourne 地产开发集团的加雷思·凯莱赫开发。丹尼尔斯坦森事务所与圣地亚哥 · 卡拉特拉瓦建筑事务所、Billings Design Associates合作完成这座摩天大楼的幕墙设计。

Chicago Spire is a skyscraper project that was partially built in Chicago, United States. The building was designed by the Spanish architect Santiago Calatrava and was developed by Gareth Kelleher of the Shelbourne Development Group. Daniel Statham Studio collaborated with Santiago Calatrava Architects and Billings Design Associates (BDA) to develop the facade of this skyscraper.

大楼高 2,000 英尺（610 米），由 150 层住宅公寓组成，总建筑面积达 278,700 平方米。该建筑每层相对于下层扭转2.4度，依次叠加至150层，完成整体360度的旋转，形成螺旋状的惊艳外观。

The building is 2, 000ft (610m) tall and consists of 150 floors of residential apartments with a total floor area of 278,700 sqm. A 2.4 degree-twist at each of the building's 150 stories from the one below it creates a total 360-degree rotation of a helical outer surface.

外墙覆层在垂直方向上被分为三个部分：基座、主体和顶部，共同构成这座令人惊叹的建筑。

螺旋塔位于湖滨大道和芝加哥河的交汇处，无论是视野还是城市交通都处于黄金地段。建成后，它将成为美国最高的建筑和世界最高的住宅楼，从顶部可以俯瞰芝加哥、伊利诺伊州和密歇根湖的景色。

It is located on the junction of Lake Shore Drive and the Chicago River, which gives it a prime location both in its view and access to the city. On completion, it will be the tallest building in the United States and the tallest residential building in the world. From the thrilling top to the building are gorgeous views across Chicago, the state of Illinois and Lake Michigan.

这座建筑被公众称之为一个巨大的「钻头」。《芝加哥太阳时报》、《芝加哥论坛报》等媒体则将其比作「一棵高耸的旋转大树」和「一片锋利的草叶」。

The building has been described as a giant "drill bit" by the public. Chicago Sun-Times, Chicago Tribune, and others in the media have likened it to a "tall twisting tree" and a "blade of grass".

设计在外立面上采用极为严格的几何构造，以便后续立面覆层系统的施工，幕墙的施工开始日期被定为2009年。芝加哥螺旋塔于2008年从地基工程开始正式动工，但遗憾的是，由于同年美国爆发的金融危机，项目被迫停工，整体计划于隔年被放弃，目前仅在原址留下了一个用于安装地基的巨大坑洞。

The design involved intense geometric rigour to the facade to enable the construction of the cladding system scheduled to commence in 2009. The Chicago Spire officially began construction with the foundation work in 2008. Unfortunately, due to the financial crisis that erupted in the United States that same year, the project was forced to halt, and the entire plan was abandoned the following year. Currently, only a massive pit intended for the foundation remains at the original site.
