Busselton Jetty

Marine & Civil

The $24 million Busselton Jetty project involves a full restoration of this Western Australian landmark to 'as new' condition.

It is a unique project that also presented some unusual challenges for Perth Precast's technical team.

The jetty was first built in the mid-1800s with additions continuing up until the 1960s. At 1,841 metres, it is the longest wooden jetty or pier in the southern hemisphere, and one of Australia's most unique eco-tourism sites.

However, by 2009 it had become structurally unsound and unsafe and its temporary closure and significant refurbishment was required.

Perth Precast was engaged by Marine and Civil to supply 1,500 concrete precast planks for the restoration.

The first challenge was incorporating a unique locking system in each individual concrete plank.

Designed by BG&E and the Shire of Busselton, this innovation enabled some movement of the panels on the stud locating pins during a significant storm event, eliminating any possible uplift of the jetty structure.

Incorporating this system, and meeting the additional challenge of manufacturing concrete elements that would be sustainable in the harsh marine environment over an extended working life was no problem for Perth Precast.

Consideration also had to be given to maintaining the heritage integrity and appeal of this iconic landmark when incorporating timber and concrete.

Drawing on our extensive experience, and working closely with Marine and Civil and their representatives, Perth Precast was able to manufacture and supply a proven product that provided cost-effective solutions to all of the project's unique requirements.

Perth Precast was also able to adhere strictly to tight supply deadlines – ensuring that the project ran smoothly with minimum disruption to this popular tourist destination.
