14层，LEED银认证的1331年马里兰州项目的设计旨在唤起哥伦比亚特区1920年代和1930年代的哥伦比亚特区大型住宅建筑。对于最好的项目法官，瓷砖工18luck官网作例证了创建建筑物美学所需的高水平工艺。一位法官说：“与瓷砖工作相关的挑战非常巨大。”
该建筑物的入口设有一个双高玻璃门户，配有磨练的Fior di Bosco大理石，六个凹槽的彩色橡木柱，一个斑马大理石人字形式底部图层和弯曲的两层镶嵌马赛克。马赛克设置在独立式螺旋楼梯后面，由大约220,000 1英寸组成。四色图案的方瓷砖零件。
To create the signature mosaic, the team conducted an extensive international search—including facilities in Turkey and China—that led them to a specialty shop in Italy that could meet the design requirements of Robert A.M. Stern Architects. The facility’s production was completely automated, using robots and machine vision technology.
Because the wall is bookmatched—with one half mirroring the other—four modules were used, each comprising about 50 unique patterns. The mosaic was created using 12-in. square sheets of tiles. Each was set in a specific direction to maintain the pattern required from the center springline of the stair. The backup wall needed to be set and skimmed to perfect vertical and lateral alignment to keep a constant radius and a perfect plumb condition. The freestanding cast-in-place stair—completed before the mosaic installation—is set off of the wall by just a few inches, so placement of the finished face of the backup wall was critical. In all, the mosaic installation required 20 months of material selection, fabrication and installation.
复杂的石头和大理石包括herri工作ngbone-patterned marble in the common area. The team used Zebrino marble, which is quarried outside of Carrara, Italy, and known for its distinct banding pattern. The material is not always available because of high demand and low production. Typically, only small quantities are available because of inconsistency within the color character and division of lights and darks within the material. The project detail called for a consistent, narrow, tight-grained variance of lights and darks, so collection of marble to those specifications took nearly 18 months.
The building’s exterior consists of approximately 1,000 pieces of precast concrete constructed from more than 800 unique molds. To maintain schedule, many panels were shipped the day after fabrication was completed. Precast erection was completed mostly during the night shift because concrete on the upper floors was completed during the day. Fior Di Bosco marble used for the entrance was reinforced with epoxy embedded stainless steel rods. The exterior base on the perimeter of the building used Chinese granite.
Crews recorded more than 1 million work hours in the 27-month project, with no lost-time accidents.
