Elizabeth Quay

Elizabeth Quay is a Western Australian Government AUD$2.6 billion project on 10 hectares of prime river frontage on the Swan River in the heart of Perth.

Elizabeth Quay will centre around the creation of a 2.7 hectare inlet surrounded by a split-level promenade, shops, cafes, restaurants and other entertainment venues. It will provide inner-city residential and commercial space as well as hotel and short-stay accommodation. 

Elizabeth Quay is an environmentally sensitive site situated on the Swan River and has received subsequent media and public scrutiny.

Thiess Services called on Cardno to provide our environmental advisory expertise prior to, and during, construction. We prepared Environmental Assessments and Management Plans to support the Works Approval applications and Planning Approvals.

We also undertook detailed contamination assessments on and offshore, provided high-level guidance on acid sulphate soil management and the treatment and discharge of dewatering effluent and excess dredge water. 

Our environmental supervision during construction also extended to emergency response services for spills, sediment plumes and marine fauna issues. We also prepared daily, weekly and monthly Environmental Audit Reports as required by Thiess Services. 

Leighton Broad also commissioned Cardno to conduct water quality and compliance monitoring of the Swan River during the bulk earthworks and excavation of the signature 2.7 hectare inlet which the development wraps around. 

Cardno's laboratory in Perth provided compaction testing and construction materials testing to the major contractors alongside Thiess Services; Civmech, DASSH JV and Decmil. This included crane pad analysis and certification, temporary sheet pile wall analysis and design review and bearing capacity analysis and certification of retaining walls.
