세계적으로 유명한 철강제품 제작 회사, Zahner의 캔자스 시티에 위치한 팩토리 리노베이션 프로젝트. 기존 팩토리의 북측 파사드의 30년 세월에 노후된 울타리 제거와 작업장 확보를 위한 프로젝트의 시작은 효율적인 패브릭케이션을 용이하게 도와주는 소프트웨어를 이용, 기업의 이미지에 부합되는 파사드 디자인에서 시작된다. 이렇게 디자인된 파사드는 기존 울타리를 대체, 주변 울타리와의 연계는 물론 건물내 워크스페이스를 확보한다. -두대의 대형 크레인을 포함한 무장애 작업공간은 연속된 무주공간을 필요로 한다. 이번 파사드 디자인과 함께 디자인된 사선지붕의 트러스 스트럭쳐를 통해 구축된다.- 패브릭케이션된 부재는 3/16" 알루미늄 플레이트를 워터젯으로 가공, 내부에 위치한 글래스 및 타공판넬과 결구되어 이중외피 시스템으로 구현된다. 오가닉한 파사드의 형상은 철을 주제로 하는 회사의 기업이미지를 투영 시킴으로써 도시환경 속 고유한 캐릭터를 생성하게 된다.

Zahner’s continuing success as one of the world’s foremost architectural
metal manufacturers prompted the need for an expansion of their
manufacturing facility at 8th and Paseo Blvd. in Kansas City, Missouri.
The location for the expansion ties into the northern façade of a
30-year-old weathering steel clad facility and re-imagines a roughly
paved concrete assembly yard surrounded by an unsightly chain link
fence.

Location: Kansas City, Missouri, USA

The design intent was to convert this underutilized area into a large
column-free assembly space, with ample clear height to move material
around on 2 large cranes, and make a seamless connection to the existing
factory floor. Beyond pure utility, the facility sought to provide
transparency, characterize where Zahner is headed in the future, and
showcase their ability to produce highly engineered forms within.
Encapsulating these values means understanding that Zahner has built
their reputation on knowing the intricacies of metal, its chemical
properties, and how they can be manipulated. Following this notion
through intensive design research, the form for the façade was derived
from metal oxidation patterns inspired by those found on Zahner’s
campus. The final graphite concept sketch drew inspiration from multiple
patterns to create a form that was specific to the proportions and
context of the expansion. Once the sketch was complete, a computer based
algorithm converted the sketch’s tonal values into a 3-dimensional
digital surface model of the façade. The resulting form grows out of the
rigid, solid geometry of the existing building’s east façade with a
single sweeping motion, and increases in complexity as it moves around
the corner to the west, paying tribute to both Zahner’s past and future.
Articulation of the abstractly based model was closely developed with
Zahner’s engineers and utilizes a variation of the ZEPP (Zahner
Engineered Proprietary Panel) system. The system’s key components are
vertically oriented DT* fins made from a half-circle shaped aluminum
extrusion riveted to a water jet cut 3/16” aluminum plate. These fins
are commonly used as a structural backup system behind many of Zahner’s
organic façades with a skin applied to their surfaces. In this case the
skin is left absent both exposing and expressing the structural skeleton
beneath. Placement of the fins is every 24 inches on center with an
Inverted Seam™ dry-set glass panel system in-between producing a
structural curtain wall set on a cast-in-place concrete base. The glass
panel system not only provides transparency between the shop’s
activities and the surrounding neighborhood, but also provides
idealistic northern light into the assembly space. This light combined
with a large structural bay (43.5’ wide) and the configuration of 2 (5
ton) cranes has led to increased productivity and production.
The result is a dynamic, rippling surface that breathes new life into the surrounding urban environment and showcases Zahner’s ability to act as a bridge between art and science.
