ASTPM TUBULAR CATEGORY WINNER
AND ARCHITECTURAL CATEGORY WINNER
CTICC, winner in the Commercial award
he project entailed the fabrication and erection
of a curved plate fabricated main entrance
arch with the suspended tubular round
shaped Globe Bar. Steel was chosen because
of the fact that complex shaped curve could
not be achieved in concrete in the short space of time.
The casino arch structure was fabricated in the
biggest possible elements, which left the least site
welded connections for erection on site. Erection of
the arch legs was done using a 220 ton crane on a
suspended fully propped slab, while lifts were taking
place. The main arch is a composite steel and concrete
structure with re-bar fi ed during the fabrication
process. Once erected and site welded, concrete was
pumped inside the plate arch using specifically
designed concrete slurry.
The Globe Bar was fully constructed offsite to get the
geometry 100% correct. The structure was then
divided into segments and welded in biggest
transportable units. Segments were then bolted and
site welded. A sacrificial inner structure of I-beams
was constructed and the external frame of the Globe
was pre-assembled on the inner frame. This ensured
geometrical correctness and the accurate fit of glass
panels.
