01. 同行——名街与市井、行人与雕像
Walk Together: High Street vs. Everyday Life, Passers-by vs. Statue 


Concrete Pavilion is an urban installation furniture specially designed for the exhibition “Heterogeneous Adventure: Duolun Road”, a special project of Shanghai Duolun Museum of Modern Art. The design intervention can be seen as a kind of interpretation and regeneration of the urban scene. We understand heterogeneity as the excavation of new possibilities from the noisy and chaotic urban context, creating space of abundant scene shift.

Bronze statues of historical figures seen everywhere in the streetscape of Duolun Road have been some urban fragments forming the rich and vibrant urban scene in the whole street, together with the vivid living snippets and fresh visitor behaviors. We chose the platform on one side of Duolun Museum of Modern Art as the site for this installation, hopefully to interact with the vacant seats by the statues across the street. The brand new sculpture was placed intentionally in parallel with the bronze statues in the street as well as the complicated city development phenomenon. Meanwhile, it is a place  for We wanted to put in a new sculpture that would parallel the bronze statues of the street and the busy urban development scene. At the same time, it is a resting place to be observed and engaged.

The site is understood as a multidimensional space of the street, the alleyway to the rear, the building, the old tree on the side, and the branches weeping from the top. The Concrete Pavilion rises from the ground step by step, extending beneath the branches of the nearby tree. Two cantilevered eave spaces are defined by the half wrapped top and the tabletop. The lower seating space faces the alleyway to the rear building, while the upper table space frames a window to observe the street. The installation itself, participates in shaping the cityscape as the background of Dolun Road.

02. 砼形——关于材料和建造
Concrete Form: On Materiality and Construction

材料的选择:雕塑混凝 | Material Selection: Sculpting Concrete


The design process of the Concrete Pavilion was an attempt to explore form, structure, material and construction simultaneously. We have chosen concrete as the material for this installation, whose plasticity allows for a sculptural form. Meanwhile, its modernity and roughness paradoxically harmonize and clash with the complex background of the street. Concrete is an interesting material. It can be mixed with recyclable waste, and has a rich variety of forms. In this experimental construction of concrete urban furniture, we tend to discuss its dilemmas and solutions in the design, production and installation process, for further promotion of its application in urban and community renewal.

UHPC超高性能混凝土 | Ultra-High Performance Concrete

在砼亭的设计中,考虑到体量和运输的问题,我们运用了一种超高性能混凝土(Ultra—Hilgh Performance Concrete,简称UHPC)。同时,我们在局部加入了透光混凝土,为雕塑增加了夜间的趣味性。

In the design of the Concrete Pavilion, we have adopted the ultra-high performance concrete (UHPC) in the consideration of scale and transportation. At the same time, light transmitting concrete has been added in some parts, adding fun to the sculpture in the night time.

UHPC is a new variety of cement-based structural engineering material with clear performance index. It innovates the composite mode of cement-based materials (concrete or mortar) with fiber and steel (rebar or high-strength prestressed reinforcement), which greatly improves the strength utilization efficiency of fiber and rebar in concrete, making a leap forward in the overall performance of cement-based structural materials. UHPC can be used to build lightweight, high-strength and high-resilience structures, completely downsizing concrete structures. The durability and working span of this structure can far exceed those of all other structural materials, such as steel, aluminum and plastic, etc.

建造:拆解、预制与搭建 | Construction: Breakdown, Prefabrication and Installation


The installation was broken down into eight blocks, under the consideration of formwork fabrication and product transportation. Connecting elements were pre-casted in between the main force-bearing blocks, while spaced connecting elements in between some non-force-bearing blocks. The longest part of the whole construction procedure is the prefabrication period in factory, where each block goes through six steps of formwork making, pouring, curing, still setting, steam-curing, and finishing. The eight blocks were sequentially connected and placed to form the final installation.

03. 瞳·心——关于观察者与感受
Pupil in Heart: On Observing and Feeling


Hopefully the Concrete Pavilion can inspire the public to observe the street and understand the city in more different angles. Concrete Pavilion is a sculpture of the street, while people sitting in it become the observer of the street. It frames varies scenes from different height, angle and position, to create interesting viewpoint for its participants.

Concrete Pavilion also provides multiple windows for people to perceive the external environment, where changes of time are merging – the traces of sunlight refracted from the shape of the boundary, the touch between the body and the concrete changing with seasons and temperature, the rain drops down the crack…

Hopefully the Concrete Pavilion can inspire the public to observe the street and understand the city in more different angles. Through the reproduction of viewpoints, the interactive relationship with the body, and the rich experience in nature, the Concrete Pavilion creates another way of understanding life for the public in Duolun Road.
