Unit1Elegant Demolition「美しい」ビル解体

大成建設が開発した従来のビル解体工事の工法とは異なる画期的な工法は、ものづくり大賞など国内の技術賞を数多く受賞した夢の工法と言われています。その工法を次の英文から読み取ってみましょう。

What do you imagine when you think of building demolition?
Do you imagine a giant steel wrecking ball, smashing into a
concrete wall and then huge chunks crashing down with lots ofnoise and dust? Or is it the spectacular sight of a building being
blown to bits using explosives? There is usually a count down – 10– 9 – 8 . . . 1 – ZERO! Kaboom! The tall building falls straightdown, followed by a huge cloud of dust.
Take a look at words used to describe such demolition: wrecking,crash, smash, noisy, dusty, etc. These are words that describe aprimitive method of destruction. They really don’t match up withthe current idea of what we think of as high technology.
However, there is a new way to bring down old buildings thatuses much more advanced techniques. Here are some of the words
used to describe this new method: novel, effective, safe, efﬁcient andeven elegant. It was created by a Japanese construction company
and can take down very tall buildings quietly and cleanly. TheTaisei Corporation has developed the Taisei Ecological Reproduction
System (Tecorep System). It is the ﬁrst of its kind in the worldand Hideki Ichihara is the engineer responsible for developing thesystem. He described it as being more disassembly rather thandemolition.
This new method involves taking a building apart, floor byfloor, from the top down, using a unique jack system to support theroof. The roof is lowered after the uppermost two floors have beentaken out. Keeping the original roof protects the project from theweather and reduces dust and noise. Beams, steel columns and theflooring are removed from each level last, after everything that canbe removed has been removed. Since building components such as
steel columns, beams and flooring are disassembled in the closed

space with the huge roof as a kind of cap, people passing by on theoutside usually only notice that the building seems to be slowly andmysteriously shrinking.
One of the reasons this method is described as being elegant
is because of the way it has been so carefully thought out. For
example, the cranes used to lower the disassembled parts use
the stored electric energy generated by descending heavy loads.
Apparently, when approximately ﬁve tons of material is loweredfrom a height of 100 meters, 100 kilowatts per hour of electricity
is generated. So the electric cranes operate only by the energy they
themselves produced in lowering the materials and there is evenenough energy for running other equipment on the site.
Such efﬁciency results in much lower carbon emissions. Also,
the fact that much of the disassembled materials are sent forrecycling makes this the most eco-friendly method in the world.
Energy conservation and generation, environmental protection andintelligent recycling are all incorporated into an operation that is
usually messy, dirty, wasteful and dangerous. It is just the opposite!
There is great potential for this new method since there are morethan 800 aging high-rise buildings in Japan. Keep your eyes open.
If you see a building begin to shrink – don’t worry, it’s all right! It
is just a construction company quietly taking down a building using
responsible methods to protect your air and quality of life.

B 本文の内容に合うように、質問の答えとなるものを a 〜 d から選びなさい。
1. Why might this new method of demolition be described as elegant?
a. Because the workers are wearing high fashion clothing.
b. It is elegant because explosives are only used in the beginning.
c. It is because it is a traditional method of demolition.
d. Because it is more like thoughtful disassembly than demolition.
2. Where does the power come from for the electric cranes?
a. It comes from lowering the roof on jacks.
b. It is generated by lowering the heavy cranes.

「もの」の一生
工学や技術は単に「もの」を作ればよいというものではなくて、世の中に送り出された「もの」には、メンテナンスも必要であり、使用後の処理の問題もあります。日本は高度成長期以来、トンネルやビルなどたくさんの「もの」を作ってきましたが、やがては作られた「後」のことも重要になると以前から言われていました。今日では、本ユニットの事例のようなビル解体技術の見事さが脚光を浴びて称えられるようになりました。
解体の過程で生じる粉塵の量や騒音を減らすこともまた、技術者が考えるべき課題として現在の社会においてますます要請されるようになっているということでしょう。
