T-UP (totally mechanized construction system for high-rise buildings) applied at the Mitsubishi Heavy Industries Yokohama Building phase 1 project. T-UP koho (sogo kikaika koso biru seko system) no jitsuyoka

Since rationalization in the construction industry has not easily been advanced so far compared with other industries, an improvement of productivity and safety of it has been regarded as a subject. Accordingly each construction company is grappling with a development of new work method for the building construction, making the totally mechanized construction as a target concept. The T-UP work method is a totally mechanized dynamic construction system for the high-rise buildings. In this method, firstly the mechatronics are added to the most modern technology regarding the building work method, design and materials, and then the uppermost story of the building is constructed on the ground in advance, and subsequently the total building is completed by making it climb up. This work method has many distinctive features, such as the shortening of work term, improvement of quality and work environment, labor saving and so forth. A study of fundamental concept has been initiated in 1988, and it was firstly applied in the new construction work of the Mitsubishi Heavy Industries Yokohama Building phase 1 project. By this application, the total term of work, which has been regarded that 30 months was required by the conventional work method, is anticipated the drastic shortening of the work term, which will be 24 months, namely about 20% of shortening. 19 figs., 3 tabs.
