Putzmeister Japan (PMJ) has been involved in the construction project right from the planning phase. PM proposed some concrete placing methods at the head office of the constructor company in Tokyo and PMJ attended the trial pumping on the site.
The constructor decided not to employ high rise pumping from the ground. Since the concrete volume is not large it would not be economical to pump up from the ground. Most of fresh concrete in the pipe line would be wasted. The tower being steel structure, only the elevator shaft and the floors are made from concrete.
