The first of its kind structure in
Singapore, FusionPolis is a 22-24 storey commercial ICT
building consisting of a steel structure framework,
supported by 3 large tower cores.
Designed by world renowed architect Kisho
Kurokawa and built by the one of the world's largest
construction company, Shimizu Corporation, FusionPolis
employs a super column construction method which has Steel
megatrusses/beams which are embedded into the cores (at 4
levels of the whole building) which in turn supports the
below 4/5 slab levels of the building through the super
columns.
One of the challenges of this project was
to construct the tower cores in advance with a projected
6-7 days cycle, in view of the extremely tight
construction period. Crane utilization was always full due
to the massive amount of steel works required.
Ehub was selected to provide a
comprehensive self-climbing wall forming solution that can
meet with the desired cycle with the limited amount of
manpower and machinery. One key challenge was to
overcome and slide past the protruded steel trusses at the
megatruss levels. Reinforcement works were also very
congested due to the large amount of loads transferred
into these tower cores.
Our solution was to apply our RailCore
solution with extremely large span units (spanning max.
9.2m x 17m high), raised by our hydraulic systems. Over
4200sqm of formwork was utilized for all 3 cores with just
115 platform units. With large span units, less resetting
times & manpower were then required.
