Self-climbing technology

Self-climbing technology and large slabtables minimise crane times

The South-East Asian city-state of Singapore – an internationally renowned financial centre and, with its very busy port, one of the largest and most modern freight handling centres in the world – is now also striving to become a top tourist destination. With its ambitious Marina Bay Sands™ project, the U.S.-based Las Vegas Sands Corporation, is currently developing a gigantic complex complete with convention facilities, casino, theatres, museum and an impressive hotel complex. The three concave-shaped hotel towers dominate the city skyline and each has 55 floors that will be connected using a sky terrace on the roof at a height of nearly 200 metres. An international team of PERI specialists from Singapore and Germany created a comprehensive formwork and scaffolding solution for the Korean building company, SsangYong Engineering & Construction. In particular, the SKYTABLE large slab tables as well as PERI ACS self-climbing technology have optimised construction progress with reduced crane times.

In each case, two asymmetrically curved legs have been positioned against each other which grow together like bridge pylons to form units. Although the three hotel towers are still identical with regard to the height and number of floors, the forms of the respective building elements nevertheless have considerable differences in terms of the base width, curvature radius and lateral offset dimension. Furthermore, the individual floors are also offset from one another in a longitudinal direction.

From the broadest product range for system equipment available worldwide, PERI provides the optimal solution in each case for a wide spectrum of requirements. Here, the variable VARIO GT 24 girder wall formwork and the column formwork – which is based on the same components – form a proven and stable basis. In addition, versatile shoring with ST 100 stacking towers are quickly and easily installed using only a minimum of system parts. www.peri.de
