Program Description

该设计/建筑实验室是一个基于项目的经验学习计划，重点是研究、开发和实施创新的建筑方法和建筑设计。学生们与当地社区和行业专家合作，构思并实现具有教育性和慈善性的建筑作品。该方案的愿望是同时加强学生成功和有意义的建筑实践所需的知识和技能，并通过丰富其建筑环境的质量，支持贫困社区的发展努力。

The design/buildLAB is a project-based experiential learning program focused on the research, development and implementation of innovative construction methods and architectural designs. Students collaborate with local communities and industry experts to conceive and realize built works of architecture that are both educational and charitable in nature. The aspirations of the program are simultaneously to reinforce the knowledge and skills necessary to the students' successful and meaningful practice of architecture and to support development efforts in distressed communities by enriching the quality of their built environment.

通过为建筑学学生提供改变社区生活的机会，设计/建筑实验室向学生展示了建筑能产生的积极影响，并激励他们树立高度的职业道德。

By framing the opportunity for architecture students to make a difference in the life of a community, the design/buildLAB shows students the positive impact Architecture can make and inspires them to high professional ethics.

项目描述

Project Description

该项目位于经济紧张的维吉尼亚铁路城镇克利夫顿·福吉(CliftonForge)。这是第二阶段的重建后工业的布朗菲尔德成为一个公共公园和表演空间，希望注入一个独特的身份感和位置在社会的中心。

The project is situated in the economically strained Virginia rail town of Clifton Forge. It is the 2nd phase of the redevelopment of a post-industrial brownfield into a public park and performance space which aspires to inject a distinct sense of identity and place at the heart of the community.

该项目的第二阶段包括一座人行桥、公园空间和一条小溪通道。推动设计的理念是，建筑元素从公园的景观中浮现出来。这座桥是一条弯弯曲曲的小径，它的坡度和台阶，既能让人们在小溪上漫步，又能在新剧院和历史悠久的市中心之间建立起直接的联系。它的中段由一片倾斜的柱子组成的森林支撑着，这些柱子在小溪边形成了一个隐蔽的栖息地。透明度是整体概念的一个组成部分；桥面和钢轨装配保持了一个薄薄的轮廓，使桥梁在现场的一个微妙的存在。整个桥梁的长度是横冲直撞，以适应现场的重大海拔变化。公园分为多个景观区，包括沿着小溪的一排高草，圆形剧场旁边的迷宫蝴蝶花园，小溪边的海滩，以及中心的一系列草坪。

This second phase of the project includes a pedestrian bridge, park space and a creek access. The idea driving the design is that the built elements emerge out of the landscape of the park. The bridge is a bent path, which ramps and steps, inviting people to wander as well as providing a direct link, over the creek, between the new ampitheatre and the historic downtown. It is supported at mid-span by a forest of leaning columns, which create a sheltered repose along the creek. Transparency was an integral part of the overall concept; the bridge deck and rail assembly maintain a thin profile, giving the bridge a subtle presence on the site. The entire length of the bridge is ramped to accommodate the site's significant elevation changes. The park is divided into multiple landscaped areas, including a line of tall grasses along the creek, a labyrinthine butterfly garden adjacent to the amphitheatre, a beach along the creek, and a series of grass lawns at the center.

Sustainability

整个工程由4种主要材料组成：混凝土、碳钢、白橡木和金属皮复合板.

The entire project is constructed with 4 primary materials: concrete, carbon steel, white oak and metal- skinned composite panels.

主要的混凝土基础由于在现有的混凝土挡土墙上支撑桥梁的一半而受到限制。这面墙经过严格的试验，以验证它的强度和稳定性。它的能力，支持桥梁的负荷，尽量减少现场工作和制造新的混凝土。

Major concrete foundations were limited by supporting half of the bridge on an existing concrete retaining wall. This wall underwent rigorous testing to verify its strength and stability. Its ability to support the bridge loads minimized site-work and the manufacturing of new concrete.

结构钢框架是预制在模块和螺栓(而不是焊接)现场，使桥梁易于和有效地组装，但更重要的是，限制废物，并允许它被拆除和回收，在其使用寿命结束。

The structural steel frames were pre-fabricated in modules and bolted (rather than welded) on-site, allowing the bridge to be easily and efficiently assembled, but more importantly limiting waste and allowing it to be dismantled and recycled at the end of its service life.

桥面完全是在当地和可持续的收获和碾磨白橡木(在10英里内的地点)。框架和扶手是由古老的白橡木制成，从遗址以前的仓库中回收(从仓库回收的材料也被用来在邻近城镇的一个农民市场展馆进行框架和包覆)。

The bridge deck is clad entirely in locally and sustainably harvested and milled white oak (within 10 miles of the site). Frames and handrails are constructed from antique white oak timbers, reclaimed from the site's previous warehouse (materials, reclaimed from the warehouse were also used to frame and clad a farmer's market pavilion in the neighboring town).

 Axonometric Bridge Stair

轴测桥阶

金属皮(锌、不锈钢、钛和铝)复合板是从制造商废物流中转移出来的终端。他们赋予了圆形剧场独特的斑驳外观，公开表达了环境意识背后的项目，并将桥面的材料调色板与圆形剧场的调色板绑在一起。

The metal-skinned (zinc, stainless steel, titanium, and aluminum) composite panels are end-runs that were diverted from the manufacturer's waste stream. They give the amphitheatre its distinctive mottled appearance, publicly express the projects underlying environmental consciousness, and tie the material palette of the bridge to that of the amphitheatre.

Urban Revitalization

维吉尼亚州的克利夫顿·福格(CliftonForge)是美国许多曾经繁荣的铁路城镇的代表，这些城市正挣扎着生存，因为推动着它们增长的工业在继续抛弃它们坐落在杰克逊河沿岸的一个小山谷里，这个阿巴拉契亚乡村小镇面临着严峻的城市挑战。空荡荡的店面、空荡荡的房屋和衰败的基础设施都会造成一种潜在的遗弃感。

Clifton Forge, Virginia is representative of many previously prosperous American rail towns, struggling to survive as the industries, which fueled their growth, continue to abandon them. Tucked within a small valley along the Jackson River, this rural Appalachian town faces severe urban challenges. Deserted storefronts, empty houses, and decaying infrastructure all contribute to an underlying sense of abandonment.

重新开发的地点提供了城镇中心小溪沿线急需的公共空间。这座桥是城市基础设施的一个重要组成部分，它将这个曾经分裂的城镇重新团结起来，促进步行能力，并将市中心内以艺术为基础的社区振兴工作的各个要素结合在一起。

The redeveloped site provides much needed public space along the creek, at the center of town. The bridge is a vital component of civic infrastructure that reunites the once divided town, promotes walkability, and knits together the elements of arts-based community revitalization efforts within downtown.

Collaboration

史密斯溪步行桥是一项慈善事业，由来自弗吉尼亚理工大学设计/建筑实验室的17名三年级建筑专业学生设计和建造。在该镇学习并与社区合作开发一个项目后，所有17名学生都为该项目提出了个人设计建议。由此，学生们反复合并他们的建议。这样，所有的学生都对讨论提出了意见。从教学的角度来看，绝对不能选择一个“方案”。相反，所有的学生都合作为这个项目开发了最终的设计。

The Smith Creek Pedestrian Bridge is a charitable undertaking that was designed and built by 17 third year undergraduate Architecture students from Virginia Tech’s design/buildLAB. After studying the town and working with the community to develop a program, all 17 students made individual design propositions for the project. From those, students iteratively merged their proposals. In this way, all of the students contributed ideas to the discussion. It was imperative from a pedagogical perspective that not one “scheme” was chosen. Rather, all students collaborated to develop the final design for the project.
