There have been developments in the deflation of Port Adelaide’s Hallett Dome.
Hallett can confirm that the dome manufacturer has already commenced the manufacture of a new air form skin and Hallett is expecting to be in a position to resurrect the dome skin air form in approximately three to four weeks.
While the investigation into the dome’s deflation is ongoing, Hallett has confirmed that there is clear evidence of an incorrect step in the construction process that has led to the dome skin failure.
Hallett is working with all parties to address this issue and any other issues that may arise through the investigation.
It has been confirmed that no harm came to any of our people or other stakeholders as a result of this event.
As is required by law, Hallett reported the incident to Safework SA and is cooperating with the Safework SA investigation while conducting its own investigation together with the primary contractor constructing the dome silo and the dome skin manufacturer.
CEO Kane Salisbury Hallett says that the incident has not affected the focus or ambition for the green cement transformation project.
“Our business is strong, our people are agile and resilient, and we are picking ourselves up and getting on with it. We are committed to making up this delay to still deliver the project on time and on budget.”
The inflatable skin of the dome is purely the outer formwork for the soon-to-be-constructed primary structure made from 17,000 tonnes of concrete and 2000 tonnes of steel which will be capable of
storing up to 52,000 tonnes of cement.
The construction technique of using an inflatable dome skin followed by an internal concrete structure has been successfully performed over 2000 times around the globe.
