来自事务所的描述。该项目位于曼哈顿上西区一块狭长的地基上，委托方想要一个使建筑面积最大化的方案。他们不希望建筑为全玻璃结构，但是窗户要足够大，同时不影响节能。

From the architect.Our client wanted a solution that maximized floor area on a long narrow site on the Upper West Side of Manhattan. They did not want an all glass building, but wanted the benefits of large windows without compromising energy efficiency.

阿姆斯特丹170大楼东接中央公园，西接林肯大厦园林区，为W68th大街创建了新的界标。大楼位于大型绿色空间和自然环境之间，这也导致了建筑架构。建筑外立面网状结构的交叉点高度不同，上升到大楼顶部，看上去立面在运动，同时能重复使用玻璃纤维预制模板和混凝土。网状结构移到围墙外部，不仅避免立柱浪费室内空间，突出的楼板和柱子遮盖在所有玻璃立面上方，用作遮阳设备。斜交网格立面联系阿姆斯特丹大道下游有气势的建筑、上西城和芝加哥的标志性建筑林肯中心。在一楼，柱子创造了动态的街墙，暴露的结构斜向人行道，并且穿过大楼顶部。在顶部，建筑的主体结束，但是骨架延伸出来，为屋顶空间创造了顶篷。在内部，裸露水泥柱成角度地穿过大楼的公共空间，穿过大厅、公共休息室、走廊的地板和墙壁，消失在上方的天花板。在房间里，通过地板到天花板的玻璃来看，建筑被外骨架的分支托起，有一种高悬在树屋上的效果。

Creating a new terminus for W68th Street, 170 Amsterdam sits between Central Park to the east and the landscaped open space of the Lincoln Towers superblock to the west. The building’s architecture and the exoskeleton that defines the exterior is derived from its location between these large green spaces and its immediate context. The intersections of the structure rise to the top of the building at different heights, giving the appearance of a façade in motion while also allowing for the prefabricated fiberglass formwork to be reused with the concrete cycle. Moving the structure to the outside of the enclosure freed up valuable interior space that would have been occupied by columns and the projecting slabs and columns provide a veil over the all glass façade and act as a shading device. The deep façade of the diagrid connects with the muscular buildings of lower Amsterdam Avenue, Lincoln Center, the Upper West Side and iconic Chicago architecture. At ground level, the columns create a dynamic street wall, with the exposed structure angling into the sidewalk and piercing the solid form of the building canopy. At the top, the building’s volume ends while the skeleton continues, creating a structural canopy for the rooftop spaces. Inside, the exposed concrete columns angle through the public spaces of the building piercing the floors and walls of the lobby, common rooms and corridors, and disappearing into the ceiling above. In the apartments, seeing the structure through the floor-to-ceiling glass has the effect of being suspended in a treehouse, held up by the branches of the building’s exoskeleton.

该建筑的外结构骨骼是由混凝土建造，向林肯广场附近的建筑遥相辉映。用于交叉柱的模板包含复杂玻璃纤维系统，系统带有多重单元，它们紧密相连以便最大程度的节约效益。结构体系和加固设计使得柱子可以形成交叉形状，获得一致的光滑表面而没有瑕疵和褪色。项目使用了小料混合，使混凝土能够放进模板的封闭区而不会振动。混凝土混合物致密、高流动性，使用灰色水泥和熔渣来获得浅灰色装饰，并且满足LEED标准。

The concrete used to create the exoskeleton is the result of a specialized mix that gives the material the appearance of limestone, a nod to the buildings in the Lincoln Square neighborhood. The formwork for the round, crossed column shapes involved an intricate fiberglass system with multiple units that were tightly connected together to achieve maximum reuse and economy. The form system and the reinforcing were designed so a pump-placing tube could be inserted into the crossed shapes, which achieved a smooth and consistent surface without blemishes or discoloration. Using a small aggregate mix enabled the concrete to be placed into the blind areas of the formwork with no vibration. The concrete mix was a dense, high fluid self-consolidating mix, using grey cement and slag to achieve a light grey finish and meet LEED standards.
