PICAC BEENLEIGH – EXPANDING FOR

On 20 August 2020, the Queensland State Government announced a grant of $20 million towards the
construction of a Queensland Apprenticeships Centre at the Plumbing Industry Climate Action Centre’s

22 PLUMBING CONNEC T ION Autumn 2021The expansion and upgrade of the current facilities will allow
for a further 200 new apprenticeship training places annually.
The Queensland Apprenticeships Centre aims to be at the
forefront of ensuring that current and future gasfitters can
safely include working with hydrogen as part of their skillset
and be leaders in a hydrogen powered industry.
Premier Annastacia Palaszczuk says, “Queensland’s
and Australia’s growing populations and economies will
also require increasing supplies of reliable affordable and
preferably renewable power. Manufacturing sectors that use
hydrogen in their processes will also benefit from a reliable
domestic supply.”
Along with the specialised gas training facilities, the Centre
will house an upgraded welding training centre, commercial
level HVAC systems in line with new Queensland government
regulations, fire protection alarm and emergency warning
systems, expanded roof safety training including safe work on
solar panel arrays and, a dedicated special hazards fire system
for the State’s only special hazards apprenticeship training.
As with all PICAC campuses, energy efficiency and
sustainability are an integral part of the design. The Centre
will feature low carbon technology such as recladding the roof
and walls with Structural Insulated Panels (SIPs), and the
installation of rooftop PV solar.
Another PICAC feature will be exposed plumbing
components that are usually found enclosed in the walls of
conventional buildings. By exposing the internal systems,
the building itself provides a working example of the latest
technologies to all learners and visitors to the facility.
The Centre’s plumbing and fire protection systems will
be installed by up to 70 plumbing and sprinkler fitting
apprentices. The aim is to assist those who have been
affected by the economic slowdown caused by COVID-19 and
to provide an opportunity to work on the installation of some
of the latest, state-of-the-art technology currently available
in Industry.
Construction commenced 30 November 2020 with
completion expected for June 2022.
