We visited the construction site of Kajima\u2019s project \u201cRedevelopment of Tokyo Kachidoki 5-chome Area\u201d on November 4, 2015. Our visit was made together with ten scholarship students and officers and staff of Atsumi International Foundation composed of Ms. Imanishi, Managing Director, Mr. Tsunoda, Secretary-general, Ms. Ishii, Ms. Ota and Ms. Honda.<\/p>\n
<\/p>\n
We assembled at a ticket gate of the Kachidoki Station of the Oh-Edo Line and walked to the site enjoying the special atmosphere of downtown Tukishima area under a clear sky. As the site was not yet opened to the public, our curiosity was stimulated. A Kajima staff explained to us about the outline of a high-rise apartment project which is under construction and its special and technical features.<\/p>\n
<\/p>\n
The construction of a 53 stories apartment started in 2013 and will be completed by December 2016. They complete five stories a day integrating their most advanced technologies. He explained also, as the most prominent feature of the project, that Kajima adopted the \u201cVD Core-Flame method of construction\u201d as Japan has frequent earthquakes which is inadequate for high-rise buildings. It is the first method of construction in the world. They install \u201coil-dumpers\u201d among three buildings which are combined together and this method absorbs the shock of earthquake. Structures of combined three buildings, called \u201cTristar (three stars) Type\u201d are strong but superior in design. Traditional box-type huge buildings give us an oppressive feeling. \u00a0But we think the Tristar type is more well-matched with the surroundings because of its being well-lighted and expansive approaches on the ground.<\/p>\n
<\/p>\n
After this explanation, we went up to the upper floor via the temporary elevator, after putting on a helmet and having a transceiver. \u00a0In our elevator which is operated at high speed, all of us were excited imagining how the site will look like.<\/p>\n
<\/p>\n
When we got out of temporary elevator, we were captivated by panoramic view of the Bay of Tokyo which was very \u00a0wide under a clear sky.\u00a0 We were impressed by such grand sites as the Loop 2 which is just before the opening to vehicular traffic, the Hamarikyu Gardens, the Tokyo Tower, the roofs of the Tsukiji Outer Market and the bridges over Sumida-River.\u00a0 All of us shouted \u201cWow! Mt. Fuji!\u201d<\/p>\n
It was a valuable experience for us that we could see, in our presence, actual \u201clight (in weight) tubes\u201d and \u201coil dampers\u201d which were explained to us just now as being the most advanced technologies. We were impressed also by the splendid clean and systematic administration of the site where Kajima execute such works like pillars, structural members, floors and wirings of each room perfectly, as scheduled. When we were told the recycling ratio of industrial wastes reaches to 98%, we recognized clearly that Kajima is very particular about creative construction.<\/p>\n
<\/p>\n
After visiting the site, we moved to a nearby \u201cgallery for high-rise apartment\u201d and visited a theatre for publicity and show rooms. The entrance hall of the gallery is decorated with modern taste as actual entrance hall.\u00a0 At the theatre, were shown the premises, urban space and living style on 3D cinema and three motion videos. Panoramic simulation of sunset, at a show room, which seems to symbolize elegant and refined living style of adults were very impressive. We had an animated discussion about sociability of high-rise apartments and a change of social structure which comes from the change of urban space from horizontal to vertical.<\/p>\n
<\/p>\n
Visiting the jobsite of \u201cKachodoki 5-chome Area\u201d was a very valuable experiences for the scholarship students. This high rise apartment, which is under construction, would be certainly a new land-mark. The under construction living apace influences the life of the residents. Apartment numbersing more than 1400 units can be said to compose a town. We expect valuable social and cultural role of \u201cKachidoki-tower\u201d in Tsukisima area in Tokyo which would show case the most advanced technologies and design concept.<\/p>\n
