Massive air dome built for hazardous waste facility

One of the world’s largest air dome structures has been built in the gold fields region of Western Australia as part of a commercial geological repository for hazardous waste.

One of the world’s largest air dome structures has been built in the gold fields region of Western Australia as part of a commercial geological repository for hazardous waste.

Measuring in at 180 metres long, 90 metres wide and 28 metres at its highest point, the air dome structure covers 16,200 square metres, the equivalent of two soccer fields in area and eight stories in height.

It was delivered by a project team comprising of Arizon Building Systems and Perth-based GR Engineering Services for Tellus Holdings.

The air dome is an engineered barrier that aims to protect the environment and human health, allowing for year-round, all-weather waste management services.

The permanent isolation system for hazardous waste in Sandy Ridge, Western Australia, will be the first commercial scale repository in Australia.

It features a relocatable anchor foundation system, air handling unites, vehicle air interlock, wind sensors, digital command controllers, full bias able system and heavy-duty membrane and air quality and ventilation monitoring.

The dome took three hours to inflate and is believed to be the first of its kind commissioned in the Southern Hemisphere.

Tellus Holdings CEO Duncan van der Merwe said the air dome is incremental in the development of a commercial geological repository for hazardous waste, that will provide an innovative infrastructure solution unsurpassed in the storage of hazardous waste in Australia.

“What was essential for Tellus in the development of this air dome structure was its ability to take into account environmental factors and in particular, the health and wellbeing of the team of people who work at the facility,” he said.

Tellus Holdings’ General Manager of Project Development Stephen Hosking said the company endeavoured to provide engineering excellence across all areas of construction for the structure.

“The air dome is perfectly suited to our requirements at Sandy Ridge and the team worked tirelessly to ensure it was delivered incident free,” Hosking said.
