Design change for Swan River bridge

The state government has approved design alterations to the Swan River pedestrian bridge in an attempt to cut $4 million in construction costs, while also announcing further delays to the bridge’s opening date.

Following advice from lead contractor York Rizzani JV, the new design will not include the black and white cladding that was planned to cover the steel arch structure.

The contractor said the removal of the cladding would retain the distinctive arch design while reducing construction and maintenance costs.

The government also said supply delays and the use of an alternative lay-down area had delayed the project by about a month, and it was now set to open in May.

The government had previously targetd a March opening.

Transport Minister Rita Saffioti said the changes would improve the structural capacity of the bridge.

“Following advice from York Rizzani JV, a prudent decision was made to remove the fabric covering so the impressive steel structure becomes the primary feature of the design,” she said

“This bridge was never designed or chosen based on its simplicity - it is a work of art. However, this decision will improve its structural capacity and expose the impressive functional elements, built locally, of the design.

“By removing the fabric covering or membrane, we make an immediate saving on construction and many millions of dollars in reduced maintenance in coming years.”

The previous design inlcuded black and white cladding.

The changes will eliminate 275 tonnes of secondary steel from the 50 arch modules and reduce wind loading and noise caused by the cladding.
