项目背景 Background
盐城外国语学校是一所在既有中学校舍根本上扩建的外语特色学校。在学校成立之初的2016年，办学方光华教诲集团委托PERFORM普泛建筑打造一栋全新的综合性传授教化大楼，一方面回应扩大了的办学规模，另一方面通报新学校的创新教诲理念。
Yancheng Foreign Language School (YCFLS) is a newly established school by adopting an existing middle school campus. In the face of increasing enrollment, YCFLS sought to build a new learning complex and simultaneously reflect the changing philosophies and values of a modern campus.

盐城在历史上曾盛产海盐，由于盐业运输以及后来水利疏通的缘故原由，全体城市水系河道纵横密布，素有“百河之城”之称。浩瀚的河道中就有个中一条河恰好从校园中部横穿而过，把校园划分成了南侧的传授教化区和北侧的宿舍区。
Yancheng, literally “Salt City” in Chinese, was a major producer of salt for two millennia. Due to the high demand for waterways to transport the salt, the city is riddled with rivers and canals. One of these rivers runs through the campus, dividing it into the Teaching Zone on the south and the Dorm Zone on the north.

选址 Siting
这栋新传授教化楼该当建在校园内何处？校方最早建议建在西侧的小树林园地内，但校园当时给人的第一感想熏染是比较空旷，传授教化区与宿舍区之间被河道和广场隔开，仅靠一座功用性的水泥路桥连接，显得有些疏远和淡漠。如果把新传授教化楼建在小树林内，并不能改进传授教化区与宿舍区之间的连接性。
Where would be the best location for the new building? The school originally considered the site in the grove on the west part of the campus. However, when we visited the campus, the first impression was that it felt empty and vast, and the teaching zone and the dorm zone were isolated by the river and the central plaza. If the new building were to be built in the grove site, it would not help the connectivity between the teaching zone and the dorm zone.

其余，贯穿校园的小河作为一个宝贵的景不雅观资源，却利用极少，两岸的外部空间大多采纳背向河道的姿态。我们认为这次新建不仅是传授教化空间规模的扩大，也是一次对校园构造重新梳理、环境整体提升的契机。
In addition, as a precious resource, the campus river was rarely taken advantage of to be part of the landscape scenery or outdoor experience. Most of outdoor spaces faced away from the river. We see the new building not only a space expansion, but also an opportunity to reorganize the existing campus structure and upgrade the overall campus experience.

经由与校方的沟通，几条方案策略成为主导：第一，保留小树林，新建传授教化楼选址在校园东西、南北两条轴线交汇处附近，东西两个半区的各自特色将更为明确，西半区的主题是自然与运动，东半区在纳入新传授教化楼后，则是一个尺度更亲切的学习生活的复合场所；第二，在新建园地及周边，通过架空、廊道、亲水平台等方法，提升步辇儿空间的连接性和舒适度，塑造一个通达性和勾留性俱佳的校园中央场所；第三，沿南北轴线植入多个公共做事空间，加强社区感，新建传授教化楼底层的报告厅、展厅、丹顶鹤主题馆（盐城的海边湿地是丹顶鹤过冬的主要基地）成为这持续串的公共功能中的主要节点。
A few new planning strategies became clear after discussion with the school. Firstly, the grove site will not be selected. The new learning complex is to be built near the intersection of the campus east-west axis and the north-south axis. The characteristics of the east and west halves will be clearer. The main theme of the western half is nature and sports. The eastern half, hopefully with the new learning complex, will be a more intimate mixed compound for learning and living. Secondly, around the new building site, pedestrian experience will be improved by adding new outdoor spaces such as ground level pilotis, walkway passages and waterfront platforms. Thirdly, more public programs will be incorporated along the north-south axis to consolidate student services. On the ground level of the new building, there will be a multi-purpose auditorium, a student gallery, and the red-crowned crane museum which exhibits how these precious birds inhabit Yancheng’s seaside wetlands temporarily when they migrate south each winter.

类型的演绎 Archetype evolution
风雨廊桥作为一种古老的建筑类型，古今中外有很多经典案例。佛罗伦萨的老桥，剑桥康河的嗟叹桥，泰顺古廊桥，还有盐城水街景区的廊桥，这些廊桥既作为交通根本举动步伐，超过河流，连接两岸，也作为行人勾留和安歇的公共空间。廊桥所具有的交通连接和容纳公共活动的双重意义，契合我们对这栋新建传授教化楼的设想期望，廊桥引发了传授教化行为的场所感和想象力，而传授教化楼为廊桥平添了活力和实用性。
The “covered bridge”, an archaic type that dates back centuries, functions both for crossing river and accommodating public activities. The Bridge Learning Center is conceived as a modern covered bridge, superimposed by a teaching building. The covered bridge provokes a sense of place and imagination to the teaching and learning activities, whereas the teaching building adds energy and pragmatism to the bridge.

至此，“桥上传授教化楼”的观点逐渐成型。桥上传授教化楼跨河而建，既赢得了所需的培植空间，同时也直接增强了传授教化区和宿舍区之间的联系，重新组织了河两岸的公共空间，让河流成为了校园日常生活场景中的积极构成元素。
So far, the design concept of a “Bridge Learning Center” has gradually taken shape. The new building is to be built over the river, which not only gains the new ground, but also directly enhance the connectivity between the both sides of the river, and make a more integral campus experience.

桥上传授教化楼的“桥头”，即主门厅，位于南岸，面向中央广场。主门厅同时也是一个300座多功能报告厅的前厅，报告厅从一层起坡至二层，其斜坡底部是桥体外部形态的直接呈现。
The main entry lobby of the building – the ‘bridgehead’ – is located on the south bank of the river, facing the central plaza. It also acts as the pre-function area of a 300-seat multi-purpose auditorium. Rising from the ground to the second level, the auditorium exposes its slope to form the image of a bridge.

从主门厅拾级而上，犹如登上廊桥的台阶，来到位于二层的共享大厅，桥面在二层标高跨过河道，与北岸的传授教化空间相遇，并汇合成一个连续阶梯状的、有天光的多层中庭。中庭不仅作为垂直向动线空间，同时也为学生课间的丰富活动供应了园地。从二层中庭往下可以“下桥”路子北门厅，通向宿舍区；往上可到达屋面活动露台。
Students and teachers take the main stair from the lobby, as if climbing “up the bridge”, and arrive at the public hall on the second floor. The building crosses the river on this level and merges with the teaching space on the north bank through a sky-lit atrium. The atrium provides diverse social and study areas for informal learning and collaboration outside of regular classrooms. It vertically connects the different levels by a continuous spiral cascading grand stair. From the second level of the atrium, you can walk “down the bridge” through the north lobby, leading to the dorm zone. Stepping up in the atrium further, you could also access the rooftop terrace.

在教诲变革的时期图景下，桥上传授教化楼是这所校园从传统公立模式向更创新多元、康健均衡的国际化教诲生态转变的一种空间回应。
Against the background of today’s tremendous education reform in China, the Bridge Learning Center reflects a paradigm shift from a passive and rigid system to a more open and diversified, but also healthier and more balanced education ecology.
学生在琴房练琴的间隙可以侧目欣赏到窗外下方的河景；美术教室中局部显现的净水混凝土的桥体构造、顶部洒下的天光，让人能真切感想熏染到当下所处的地点和周边的环境；课间时候，有了更多的同学会走出教室，来到沿河外廊上凭栏小憩；河边的亲水平台不断地迎来嬉戏活动的学生。在这里你既是参与者也是不雅观察者，真应了那句话，“你站在桥上看风景，看风景的人在楼上看你。”
Students can easily enjoy the river view down below the windows while practicing in the piano rooms. The partially exposed bridge concrete structure in the art classroom, and the natural light from the ceiling skylight, let people truly be immersed in the moment and surrounding settings. During breaks, more students will walk out of the classrooms and come to the corridors along the river to rest. The riverside platform and the drawbridge form a cinematic setting, where students and teachers constantly walk by, and they are performers and audiences at once.

构造与建造 Structure & Construction
桥体在河道之上的跨度有将近二十五米，方案采取了三组预应力混凝土桁架作为跨河部分的核心构造，从三层的桁架到二层的吊柱，再到河面之上步辇儿桥的钢吊杆，构造的呈现自上而下由重至轻，分别与各层不同的透明度需求相匹配。
To overcome the structural challenges imposed by the bridge’s 25-m long span, we use three sets of pretensioned concrete trusses. Located on the third level with full floor height, the trusses hang the tension columns on the second level, while the pedestrian drawbridge is hung by eight thin steel rods. From the trusses to the tension columns and then to the steel rods, the structure members become lighter towards the river, matching the transparency needs of different levels.

桥体三层紧张为美术、音乐、琴房等艺术类教室，由于房间隔墙的存在，桁架构造在个中时隐时现，无法感知全貌，彷佛在以一种不愿定性寻衅着常规传授教化空间的边界。而二层的共享大厅由于吊柱的利用，空间得到了最大程度的透明性，一条通透的东西向视线走廊，架在河面之上，供应了一个之前从未有过的感想熏染校园的视角。
On the third floor right above the river of the Bridge Learning Center are the most of art, music and piano practicing classrooms. The room partitions hide the truss structures partially, so the whole picture of the structure can not be perceived. This seems to challenge the conventional teaching space limits with uncertain boundaries. The use of tension columns makes the second level public hall open and transparent. An east-west view corridor, unobstructed above the river, provides an unprecedented perspective of the campus.

项目施工期间，PERFORM普泛建筑派驻场建筑师全程参与了建造过程。作为一个本钱掌握严苛的项目，不少过程中的难点都较大依赖了现场的及时沟通和对接，例如外立面遮阳铝百叶的细部打样，桥底木纹铝板的安装，以及室内中庭吊顶的造型。
During the construction, Perform appointed site architects to participate the entire process. As a strict budget control project, quite a few tough implementations relied on the constant and timely communication through the site architects, such as the facade shading louver mock-up, the installation of aluminum composite metal panels at the bottom of the bridge, and the form-finding of the drop ceiling of the atrium.

尤为分外的一点是，这个屋子发展在一个既有校园里，在未来利用者的关注下不断地成长，这样的环境也给了屋子完善自己的机会。施工过程中，一些材料的选样和空间的详细利用问题及时得到了师生们的反馈，这该当也是场所意义形成的过程。
The unique part is that the new building grows in an existing campus, surrounded by the attentions from its future users, which actually gave the building chances to improve itself. During the construction process, we received feedback from the students and teachers regarding the material selections and space uses. This also contributes the forming of the sense of a place.

结语 Epilogue
项目建成后我们回访学校，一队学生从吊桥上走过，看到河里游着的鸭子和鹅，有好几位小朋友不禁开始大声背诵“鹅鹅鹅，曲项向天歌…”，那一刻每个人的表情是轻松和清闲的，这个由学生、动物、屋子、小河共同组成的场景，让人感想熏染到了校园自己的生命力。
After the project was completed, we came back to the school. A few young students walked by the drawbridge, as they saw the ducks and geese swimming in the river, they couldn’t help but start reciting the poem “geese, geese, geese, song of the Tiange...” The scene composed of students, animals, landscape and the building, was full of the vitality and youth of the campus.

海德格尔曾说，"桥让大地聚拢为河流四周的风景"。建成后的桥上传授教化楼成为了校园的中央，人们乐于容身在吊桥或是架空层下休憩和互换。它重新开启了一个天下，开启了师生们对人、建筑、自然之间关系的再次认知。
As Martin Heidegger once said, “The bridge gathers the earth as landscape around the stream.” The Bridge Learning Center has become the central place of the campus. People enjoy hanging out around the drawbridge and open piloti area. It opens up a new world for students and teachers, where the relationship among human, nature and building is different from before.

学校把新大楼命名为创新中央 “Innovation Center”, 可能很多人并不知道实在这条河的名字原来就叫做改造河，名字的由来无从考证，但推测该当来自上世纪五六十年代的群众性改造运动，这个名字代表了那个年代特有的精神力。“逝者如此夫，不舍昼夜。”或许当本日的创新中央超过在改造河之上时，这个校园在韶光的长河里开始了她新的动身。
The school named the new building “Innovation Center”. Many people may not know the name of the river was also called “Gexin River”, meaning innovation or revolution. The name’s origin is unclear, but probably came from the mass revolution movement of the 1950s and 1960s in China. It represents the unique spiritual power of that era. “The passage of time is just like the flow of water...” Perhaps when today’s Innovation Center straddles the Gexin River, the campus has begun her new journey in the mists of time.
