The roof structure had to be developed in such
a way that large spans were incorporated with
minimal impact on the structure below. The roof
geometry was relatively complex, however the
design solution needed to be relatively simple to
enable easy installation on site.
The roof structure and associated feature
columns were designed and constructed with
structural steel lattice trusses, girders and lattice
columns. The lattice structure in turn is clad
with smooth aluminium cladding giving the roof
structure the crisp finish that was desired.
The structure supporting the multi-level façade
also provides vertical support for the roof structure.
This structure was designed and constructed with
conventional I and H structural steel sections. The
roof and façade structure are braced to the adjacent
reinforced structural buildings which provide the
required lateral stability for these structures.
The atrium areas also had feature columns that
were constructed from welded up structural hollow
sections. A number of these columns are features
with no structural significance, however three of
these columns are design to provided vertical
support for the roof structure.

HVAC
An energy efficient variable air volume system
supplies conditioned air from air handling units
located on the façades.
The cooling source is provided by air-cooled
chillers located on the roof, not using any water.
Fresh air is drawn at high volumes from the
façade plant rooms to ensure a healthy environ-
ment and minimise energy usage when outside
conditions are favourable.
Carbon dioxide levels are monitored and
controlled in the office areas to enhance indoor
air quality.
The basement ventilation system controls
Carbon Monoxide levels to ensure a healthy
environment and minimise energy usage.
Various tenant server and data areas are served
by close-control computer room air conditioning
systems linked to the central chilled water system.
A full BMS system monitors and controls all
HVAC systems to optimize energy usage.
All key building services are centrally monitored
and logged by the BMS (water meters, energy
meters, lifts, escalators, heat pumps, fire systems
and sump pumps).
