RECONVEXO 是一个创意征集比赛，关于里约热内卢地铁站扩建项目后剩余材料的再使用。材料是6000多块原用于Line4 (4号线)和Gávea站的隧道连接。扩建本该和其他扩建项目一起开始，作为里约2016年奥运会的准备工作，但缺少资金，该项目导致大量混凝土预构件闲置。RECONVEXO竞赛的目标就是重新发掘这些预构件的用处。


介绍

2016里约奥运会这样极具规模的盛事，易于吸引投资和加快内部资源使用，已经为里约的转型项目融资。联邦、市政公立和私立部门集得的大约300亿美元对国家停止多年的改造计划起了巨大推动作用。

里约奥运会留下的不只是体育场馆或其他设施，之后都不能被闲置在一边。奥运会是否对实现长期城市政策有益？我们扩大城市基础设施的决定是否正确？运动盛会真的能把里约变成一个更好的城市吗？谁会最终获益？


非物质遗产

遗留问题：很难解释，概念模糊，颇具争议

遗产本就不能仅关注在物质上，还有非物质的那部分。

我们要问问自己，整个决策过程有多少不算是解决遗留问题呢？


不可预见的遗产

奥运会不总那么美好，举办后城市经济受损和建筑设施闲置的事时常发生。6784个混凝土预构件就是2016里约奥运会没有预见的后遗症，它们代表着错误的城市规划带来的损耗。

RECONVEXO竞赛寻求对里约这个城市真正需求的创意和关键性的反思

RECONVEXO is a competition of ideas for the reuse of the remaining staves from the expansion works of Rio de Janeiro’s Subway.
There are more than 6,000 staves originally intended for the tunnel connecting Line 4 to Gávea Station.
This stretch should have been inaugurated along with other stretches executed for the Olympic Games Rio2016. Today, due to the financial crisis in the State of Rio de Janeiro, the execution of this expansion work is indefinitely on hold. The result is a huge amount of precast concrete parts with no certain destination.
To reinterpret its possible uses, to redefine its meaning: this is the purpose of the RECONVEXO Competition.

INTRODUCTION
A major event in its size and complexity, seen as a great opportunity to attract investments and accelerate the application of internal resources, the Rio2016 Olympic Games have leveraged transformations in Rio de Janeiro.
With resources of around R$30 billion from the federal, state and municipal governments and from public-private partnerships, the city moved from the relative stagnation of the previous decades to a massive process of urban reformulation.
Considering that the main legacy of the Rio2016 Olympic Games is not properly the construction of sports equipment, and that these, like other structures, should not suffer the side effects of ostracism and underutilization, would the Games have contributed effectively to the implementation of a medium or long-term Urban Policy?
Have we expanded the city infrastructure in the right direction?
Were the Games really catalysts for a fairer city?
After all, who were the main beneficiaries?

Immaterial legacy
Legacy: complex word, ambiguous, possibly controversial.
From the outset, legacy is something that should not be understood only in the material sense, of concrete works. There is also a legacy in the immaterial sense.
We must ask ourselves: To what extent the total opacity of the decision-making process of the games is not part of our legacy?
The urgency in the process of urban transformation for the Games, did it not reinforce Rio’s citizens difficulty to collectively coordinate, their historically small ability to mobilize for urban solutions?
In what measure is this reiteration of our difficulty to self-reflect on the city not part of the legacy of the Games?

Unforeseen Legacy
Although it has always existed, the Olympic legacy has not always been positive. On the contrary, it has often boiled down to idle structures in financially ruined cities.
Object of this competition, the 6,784 unused precast concrete pieces are an emblem of the unforeseen legacy of the Rio2016 Olympic Games. They represent the leftover portion, the margin of error of this transformation process, the waste, the erratic urban planning.
RECONVEXO Competition summons upon a reflection on the real needs of the city of Rio de Janeiro, through the elaboration of imaginative, critical and poetic proposals for the use of these pieces.

The staves
Structural parts for the tunnel installed by (TBM), popularly known as “Big Armadillo”, each set of 8 staves composes a ring of tunnel structure.

Each ring has 4 types of pieces:
– (5x) “A” pieces of regular external size 0,4m x 1,84m x 4,77m make up the main part of the ring.
– (1x) part “B” and (1x) part “C”, both with external trapezoidal shape 0,4m x 1,84m x 5,02m(variable), in order to facilitate the fitting of the last piece – “K”.
– (1x) “K” piece with external trapezoidal shape 0,4m x 1,84m x 1,58m (variable) which functions as the ring closing wedge.
Once coupled the pieces form a ring with 11,13m of radius.
The manufacturing process used metal molds supplied by the manufacturer of TBM (Herrenknecht Tunneling Systems, Germany) filled with fiber reinforced concrete, subjected to thermal steam cure for 6 hours and stockpiled for at least 28 days.
From the stockpiling the staves are led to the entrance well of the tunnel, where they are installed by the TBM itself.

SELECTION CRITERIA
Proposals should:
– Interpret the meaning of the Olympic legacy. In other words, they should question how punctual public investment can improve the city and the ways in which its inhabitants can relate to it
– Promote the enhancement of urban space and greater equity in the population’s access to it
– Use as much as possible of the available material
– Use the staves within the municipality of Rio de Janeiro Comments
– There are no restrictions of any kind on how the parts will be used
– Use the virtual models of the staves made available in attached annex to this edict
– The accuracy of these models is approximate, however, in order to match the proposals, the models cannot be changed, under penalty of disqualification
– Despite being a competition of ideas, and as such not being tied to technical feasibility, the proposals are expected to be based on structural common sense
