WA’s biggest manufactured bridge beams installed on Perth’s METRONET project


The biggest Tee-roff beams ever manufactured in Western Australia were installed as part of the METRONET Thornlie-Cockburn Link over the weekend.

The Thornlie-Cockburn Link will be Perth’s first east-west cross line connection, making travel around the city by train more flexible and providing a higher level of public transport service to Perth’s southern suburbs.

Local company, Georgiou Group, manufactured the 50-metre beams at its precast yard in Hazelmere. Each beam consists of 14,000kg of reinforced steel, 120 stressing tendons and 73 cubic metres of concrete.

According to the company, they each weigh 197 tonnes and took 10 workers and two concrete pump trucks three days to manufacture.

Transport Minister Rita Saffiot said seven of the 10 beams were installed over the weekend, with the last three to be installed as the project progresses.

“METRONET is about supporting local WA jobs and our local manufacturing industry – these bridge beams are a great example,’ Ms Saffiot continued.

“Not only are they the biggest Tee-roff bridge beams ever built in Western Australia, they were manufactured locally in Hazelmere.

“More than 1,680 local jobs will be supported through the Thornlie-Cockburn Link project over the next few years, while hundreds more will be created on other major projects in our southern suburbs that complement this project including the North Lake Road Bridge.
