DFA提出利用最高的木制观测塔来治理中央公园水库
DFA proposes tallest timber observation tower to clean Central Park reservoir

纽约DFA建筑工作室设想在纽约中央公园内建设预制结构的木制观测塔，这座观测塔既可以过滤被污染的水库，也可以用于眺望纽约的城市景观。

New York studio DFA has envisioned a prefabricated timber tower for New York's Central Park that would both filter a contaminated reservoir and provide views over the city.

观测塔的高度暂定712英尺（约220米），坐落在Jacqueline Kennedy Onassis水库中。水库占地106英亩（约643亩），覆盖了公园区域的八分之一，其中含有十亿加仑（约450万立方米）的污水。

DFA的建筑师说：“水库主要为周边地区的游泳池和Harlem Meer地区供水，而现在的状况却使水资源短缺，整个水库成为一潭死水，对数以百万计的纽约市民、游客以及周边动物的健康造成威胁。”

The temporary 712-foot-tall (220-metre) Central Park Tower would sit in the Jacqueline Kennedy Onassis Reservoir, a 106-acre man-made lake that encompasses one-eighth of the park's area and contains one billion gallons of contaminated water.
"Aside from supplying water to the pool and Harlem Meer, the Reservoir sits stagnant and fenced off due to its current state as a health threat to millions of New Yorkers, tourists and animals," said DFA.

该方案的理念是将一个过滤系统融入在结构中，使有害的水体转为可用的水资源。

同时观测塔还将提供一条环形上升的观景台，让人们能够亲眼目睹水资源的清理过程。

The firm's concept imagines the structure would contain a filtration system in its base, which would turn the hazardous reservoir into a useable pond.
It would also provide a series of ring-shaped viewing platforms on its upper levels, creating a tourist attraction to be used during the clean-up process.
     

工作室创始人Laith Sayigh表示：“DFA所设想的这个临时性地标，创造性地将水库资源改造成纽约最大胆的城市基础设施。”

这个概念项目激发促进了这座历史悠久的城市的更多可能性。”

"DFA envisions a temporary landmark that is remarkably of its time to creatively transform the reservoir into one of New York's boldest urban amenities," said studio founder Laith Sayigh."This conceptual project pushes the boundaries of what we perceive is possible in a city as dense, historic and environmentally vulnerable as ours."

该塔由弯曲的胶合层压木材梁的格子构成，该木梁将在不到六个月内在现场制造并组装而成。

拉伸钢丝绳将锚固到预制混凝土基座，用于稳定结构，塔的主体则由一对螺旋结构组成，在 375英尺至500英尺（约114米至152米）的高度间利用坡道平台进行连接。

The tower would be constructed from a lattice of curved glue-laminated timber beams, which would be manufactured off site and assembled in less than six months.
Tensile steel cables would be anchored to the pre-cast concrete base to aid stability. The tower's main body would be formed by a pair of helix structures, with a ramp in between the two layers from the 375- to 500-foot (114- to 152-metre) height marks.

人们可以通过塔体的多孔表皮材料看到其中的核心筒，同时也让游客在上升的过程中将景色尽收眼底，最终达到360度开放视野的景观平台。

顶部的风力涡轮机将为过滤系统、电梯以及顶部112英尺（约34米）高的照明杆提供能量。如果建成，该塔将成为世界上最高的木结构建筑。

Covered with a transparent material, its outer skin is designed to be more porous than the inner core. This would allow visitors to take in the views as they spiral up the ramp, culminating at the 360-degree viewing platform.
A wind turbine at the top would generate power for the filtration system and the elevators to the observation decks. Crowned with a 112-foot-tall spire that doubles as a lighting rod, the tower would become the world's tallest timber structure if it was built.
   

Sayigh说：“中央公园观测塔有潜力成为其他城市的示范项目，其目的是修复现有的基础设施，建立高度视野，提升城市的公共视角。”

中央公园是美国访问量最大的城市公园，由景观设计师Frederick Law Olmsted和建筑师Calvert Vaux在1857年设计，于1873年完成，现有规模为843英亩（341公顷）。

"The Central Park Tower has the potential to be a model project for other cities aiming to fix existing infrastructure, build tall to capture views and elevate the urban public realm," Sayigh said.
Central Park is the most visited urban park in the US. Designed by landscape architect Frederick Law Olmsted and architect Calvert Vaux, it was established in 1857 and completed at its current 843-acre (341-hectare) size in 1873.
