The Landside Design and Construct phase, for which JDSi has partnered with Ertech, is a component of the wider airport development which attracted over $70m of Federal, State and Local Government investment.

Key Considerations

  • Working with the Client and Project Stakeholders to continuously seek improvements in value, efficiency and productivity.
  • Undertaking design of major services including power, water and sewer.
  • Identifying engineering opportunities and negotiating with authorities to improve financial viability of the project.
  • Understanding both the short term and long term viability of the development, both from an airport operations perspective and a commercial development perspective.
  • Ensuring the detailed design responded to key site constraints and locally available materials.

Project Challenges

Difficult Site Conditions

Through detailed site investigations it was determined that the existing materials on site and high water table presented a number of unique challenges for both the design phase and construction phase. JDSi bought in additional technical resources to ensure all constraints and opportunities were well understood and documented prior to commencing the detailed design. This process ensured that the detailed design responded to the existing constraints and minimised any costs associated with ground improvements, export and import of material and stormwater and groundwater management.


The landside component, being a design and construct project, had a challenging project schedule. JDSi were able to implement a progressive design process, whereby the key site constraints and risks were mapped out early and then detailed design components were progressively supplied to the contractor to ensure the site works progressed in line with Client and Stakeholder expectations.

Authority Negotiations

JDSi were responsible for liaison with key stakeholders, including Western Power, Busselton Water and Main Roads WA to achieve engineering approvals for a number of complex items including a HV metered supply, potable and fire water supplies and an intersection upgrade on Vasse Hwy. Through JDSi’s extensive knowledge of service authority processes, coupled with an understanding of long term development economics, we were able to ensure the current and future infrastructure and service capacities suited the long term planning and objectives for the development, whilst minimising redundancy and overspend during the early stages.
