Managing the Swan River During the Development of Elizabeth Quay
Leighton Broad, WA
Leighton Broad (LB) brings together two specialist organisations Leighton Contractors Pty Ltd and Broad Construction to deliver the inlet and public space development works for Perth’s iconic Elizabeth Quay foreshore development.
The Project involves the construction of an inlet, island, pedestrian bridge, ferry terminal, short stay jetties, and public realm that includes a water feature and food and beverage outlets.
Elizabeth Quay is situated on the Swan River foreshore, just west of Barrack Street Jetty – an area of land that was reclaimed from the river throughout the early 1900’s. Since that time the river has been subjected to pre-existing and complex ecological stresses including nutrient run off, increased sediment loads, rubbish accumulation and increasing development along the river way.
To protect river water quality and ecology LB developed rigorous monitoring programs, adopted industry best practice, scientific review and the drive to implement environmentally sensitive methodologies during construction.
Environmental requirements onsite have been diverse, including the management of Acid Sulphate Soils (ASS), European and Indigenous heritage, marine fauna and seagrass communities, groundwater, waste management, contamination and remediation and disposal and re-use of bulk excavated material.
While consideration of all of these environmental aspects has been fundamental to environmental management on site, the most significant to date has been implementing sustainable water management; maintaining river water quality surrounding the Project area during dredging of the Swan River, inlet excavation and connecting the inlet with the Swan River and dewatering management.
