The Cape Jaffa development comprises over 600 lots of land for residential and commercial operations. Tonkin Consulting provided all master planning advisory services from environmental studies, land use scoping through to developing the detailed design of all civil infrastructure and services. Environmental coastal investigations on sand movement, sea level rise, tidal flushing, groundwater modelling and marine ecology surveys. Social impact studies were undertaken to assess possible effects of the development on the local community and region with findings incorporated within the EIS.
Due to the development’s remote location (it was 20 kilometres from major service infrastructure services) many background studies were undertaken to provide information and data for assessing local impacts. The data was monitored, collated and used to create the several models for the project. Tonkin Consulting assisted with the various statutory documentation required for approvals, such as negotiations for a sea bed lease, concrete batching plant approval, mining leases, a wastewater treatment facility and town water supply allocation from confined and unconfined aquifers. It managed referrals to government agencies and lodged an Environmental Protection and Biodiversity Conservation (EPBC) Act submission for the project.
Tonkin Consulting prepared detailed design for Stages 1 and 2 (200 lots) responsible for all service infrastructure including sewer and water reticulation, headworks infrastructure including onsite treatment plant and wastewater treatment plant and electrical and telecoms services. Tonkin Consulting was part of the project construction team identifying construction efficiencies, cost management and verifying design. A key design point devised for time and resourcing efficiency was utilising existing materials from the site. This innovative approach to design involved fabricating reconstituted limestone blocks for the water edge treatment construction.
