Gold Coast Airport –
Joint User Hydrant Infrastructure (JUHI)
The project focused on the construction of Joint User Hydrant Infrastructure (JUHI) and extension of existing fuel lines on the domestic apron of the Gold Coast Airport. SEE Civil successfully relocated the Caltex fuel main from Bay 10 to Bay 7.
It was an integral project to ensure the airport could cater for the increased usage demands of large international planes prior to the 2018 Commonwealth Games.
The project consisted of airside works in its entirety and included excavation, shoring, dewatering, trenching, structure construction and reinstatement. SEE delivered an accelerated program on time and on budget to facilitate the Commonwealth Games capacity requirements.
Project Scope
- Airside underground service location and demolition of existing features around the fuel main and exposing main in vicinity of valve chamber.
- Trenching, shoring and dewatering along the operational airside pavement as required to facilitate the new fuel main. Trench excavations up to 4m deep in sand and indurated materials
- Full airside apron pavement rehabilitation.
- Complex staging around airside operations.
- Construction of concrete structures including valve chamber pits and hydrant biscuit slabs.
- Safe removal and relocation of spoil from highly sensitive operational area.
- Development and implementation of Construction Environmental Management Plan (CEMP) including specifics around PFAS and ASS management.
- Detailed geotechnical testing to identify possible soil volatilities.
- Introduced high levels of environmental testing and sampling to ensure the water quality did not depreciate.
- Provision of safe access to pit chambers and trenches, for third party mechanical contractor.
- Reinstatement of excavations and trenches with lean mix concrete.
Key construction elements
- Delivered in eight discrete sections that required commissioning for each section prior to commencing the next.
- Careful delivery of works around (and without disruption to) existing service infrastructure, including a high-pressure fuel main (A1 jet-fuel) which had to be carefully excavated using high pressure jet blasting around existing live fuel main during valve chamber installation works.
- Delivery of the Project without environmental or major safety incidents, including working with strict CASA safety and security requirements.
- The close and successful work with other contractors and the client to deliver the project ahead of time and ahead of the Commonwealth Games travel period.
- Planning and execution of 5,000 vehicle movements to and from the project site under airport security escort and SEE Civil supervision.
