The Army Commercial Centre in Oakey, Queensland, contains administrative offices and a precinct dining and café area for the Department of Defence (ADF) Swartz Barracks personnel who defend and protect Australia’s interests every day.
The ageing buildings and infrastructure needed refurbishment to ensure the centre continues to support day-to-day life for personnel at the barracks.
Aurecon was contracted to undertake the engineering design and project management of the replacement centre that was delivered within Defence’s Estate Works Program.
Temporary facilities were established to continue the provision of services, while the new commercial centre was under construction.
The existing commercial centre was demolished and the new centre accommodates Army and Air Force canteen service facilities which includes a new entrance and new dining and café spaces, together with new administration offices, a Defence Bank branch, and car parking facilities.
Thinking outside the box for construction during coronavirus
Carrying out construction works at the height of the COVID-19 pandemic in Queensland posed a serious challenge to the project. To ensure the project remained on schedule, a change was proposed to the new centre’s foundation design.
Shifting from a deep concrete waffle slab to concrete driven piles with a thinner slab meant that construction personnel were not near each other, which contributed to the prevention of any spread of coronavirus.
The project team achieved a zero-harm outcome through the comprehensive and uncompromising management of risks, particularly those relating to health, safety and the environment.
A number of factors were considered when designing the project schedule. Demolition took place with minimal disturbance to base operations and traffic flows. This included the safe management of construction debris, which contained contaminants such as lead paint and asbestos.
More than 100 cubic metres of contaminated soil and crushed concrete, generated during the excavation and foundation works, were reused at the barracks by a separate contract that involved the construction of a new helicopter slope-training pad. It is an example of the considerable attention Defence is placing on reducing waste to landfill and forging a more sustainable circular economy.
The outcome was excellent for both projects and mitigated some of the landfill disposal costs incurred on the commercial centre project.
Despite the start of construction coinciding with the worsening pandemic, the project remained on schedule and the certificate of completion was awarded nearly two months ahead of schedule.
