created using precast concrete retaining walls
and an extensive undercroft area.While the
rear of the building – at four storeys high
– makes a bold architectural statement, the
front of the building remains in keeping with
the surrounding architecture of two-storey
Victorian villas and is not dissimilar in size
and shape to the original school. Several
features of the old school have been retained
and incorporated successfully in the new
school, including the clock tower and stone
portico, each of which are now displayed
proudly in prominent positions.
The building comprises a four-storey,
concrete-framed horseshoe-shaped main
teaching and administration block, with a
steel-framed two-storey sports block attached
to the west teaching wing. Columns were
minimised within the teaching zones to
maximise teaching spaces and create internal
flexibility. The post-tensioned concrete
frame solution was designed on the basis of
an 8 × 7.5m grid and a 225mm-thick slab.
The use of a post-tensioned slab allowed
shallower slab depths, increasing floor-to-
ceiling heights and reducing foundation and
column sizes significantly from those of a
conventional reinforced concrete frame.
To ensure the building structure
accommodated the building services strategy,
adequate provision for major services
distribution was incorporated within floor and
ceiling voids, and was unhindered by the level
soffit of the post-tensioned concrete slabs.
A two-hour fire rating was required. The
concrete columns and slabs achieved this without
any special measures, while the steelwork was
required to be fire protected.
