| Project Description | Design and construct of a new water reticulation system using tunnel boring |
As part of the City Botanic Gardens Master Plan, Brisbane City Council has been undertaking improvement works to ensure that the City Botanic Gardens continues to be a place all can enjoy and that its heritage values are protected now and into the future. As part of the improvement works, the City Botanic Gardens‘ water reticulation infrastructure was replaced.
This project involved the design and construct of a new water reticulation system throughout the City Botanic Gardens, connecting to Urban Utilities mains supply in George St. The reticulation system was installed using tunnel boring and open trench excavation.
The City Botanic Gardens is listed as a State Heritage Place and in undertaking the project, Roman Contractors adhered to the requirements contained in the Queensland Heritage Act 1992. Roman Contractors also performed the project having regard to the environmental sensitivity of the area, including working with a supervising Arborist to support the works involving tunnel boring near significant vegetation, and also ensuring that construction avoided disturbance of any fauna species in the area. Notwithstanding the cultural and environmental sensitivity of the construction footprint, Roman Contractors managed time efficiently to deliver the project in a timely manner and to budget.
The replacement of the water reticulation infrastructure in the City Botanic Gardens will ensure the efficient, reliable and secure supply of water to the Brisbane Botanic Gardens, in addition to the Café, Riverstage, QUT ferry terminal and the services of the Goodwill Bridge. The upgrades will improve the operation and connectivity of the Brisbane Botanic Gardens, so the Gardens can continue to be a place that is enjoyed by all.
