branch commenced involvement with Grocon Constructors
Pty Ltd at tender stage, working with them through early
to mid 2007 mainly looking at solutions for supporting
the roof structure.
Our involvement with supplying material to the project
commenced with the client requiring a versatile, labour
saving solution to support reinforced concrete beams
ranging up to 950mm deep x 1800mm wide in the podium
slab areas. These beams in turn carried additional loads
from hollowcore slabs. We designed and supplied Alshor
Plus with Albeam and Alform to cater for the high loads
whilst providing the advantage of fast erection and dismantling
of the falsework.
Having used Alshor Plus on propping
heights of around 4.5m and experiencing the versatility
of the system,
the client then decided to use it as a high level support
system to provide shoring to an area of beams and slabs
at level 3, approximately 18m high. Levels 2 then 1 were
constructed “top down” with the same system.
This allowed critical early preparation work for the
roof to be completed.
Alshor Plus was then utilised on various
high load shoring applications throughout the construction
of the substructure,
concourse slabs and grandstands.
Installation of the unique roof commenced during late
2008 and having utilised Alshor Plus in various soffit
support applications, the client decided that the system
was the best solution to provide support and combined
access for fitting roof panels. The project management
team identified that the high leg load capacity and generally
2.4m Frame size of Alshor Plus would equate to less components,
quicker erection and dismantling times, greater versatility,
and reduced labour costs when compared to traditional
scaffold/support systems.
The main loads from the roof
during installation are being catered for by Megashor
Towers positioned under
each groin which forms the junction of each shell profile
on the bio-frame roof. These Megashor Towers have been
designed to incorporate special “headstock” arrangements,
designed and supplied by the client, which connect to
the node points on the roof. It is estimated that there
will eventually be twenty such towers, one positioned
under each groin when the roof is fully in place. The
highest of these four legged towers will be approximately
24m from its base to the underside of the roof. Hiring
Megashor has allowed the client a greater degree of flexibility
in their considerations for supporting the roof compared
with the alternative of structural steel fabrication
and purchase. It also means that components to make up
each Megashor Tower can be supplied to programme for
assembly as required.
