Coastal engineering works in the spotlight

Coastal engineering works in the spotlight Completed reconstruction project on the Scenic Highway at Statue Bay.

The reconstruction of the Scenic Highway at Statue Bay in the Livingstone Shire is among the works in the spotlight in what professional body the IPWEAQ has dubbed ‘coastal engineering month’.

The Institute of Public Works Engineering Australasia in Queensland (IPWEAQ) has created a 2021 calendar – Every Community Needs an Engineer – and January has been earmarked to celebrate the engineers protecting the state’s expansive coastline.

Activities to mark the month include a Public Works TV session from midday on January 20 focused on City of Gold Coast projects (details HERE) and a mini-conference.

The conference is available to access through IPWEAQ’s website at https://www.ipweaq.com/mini-conferences until June 30 at a cost of $100 plus GST for IPWEAQ members and $200 plus GST for non-members.

The issues covered include:

Scenic Highway, Statue Bay Cyclone Marcia reconstruction project

In February 2015, Severe Tropical Cyclone Marcia crossed the Queensland coast north of Yeppoon in Central Queensland, causing extensive damage to infrastructure and the community. The singularly most significant damage to infrastructure in the Livingstone Shire was the undermining of the coastal Scenic Highway at Statue Bay and the concurrent failure of the steep cliff-face above. This paper outlines the reconstruction of the highway, from the initial damage caused by the cyclone, through the approval processes and design of the restoration solution, to the construction of the approved scope of work; highlighting the challenges of managing a complex infrastructure project in conjunction with community expectations and NDRRA guidelines.

Flying Fish Point rock revetment upgrade: the application of ‘green engineering’, fish-friendly features and other innovative measures

Flying Fish Point is located immediately north of the Johnstone River mouth and has a well-documented history of shoreline erosion. The Cassowary Cost Regional Council has undertaken a variety of mitigation measures over time, including the construction of rock revetment structures. In 2017 it resolved to remediate the existing rock revetments between William and Ruby streets, Flying Fish Point. The presentation explores the key features and outcomes achieved through the design process for the Flying Fish Point community and key stakeholders.

Connecting Communities: Innovative fibre composite solutions for infrastructure – from swale bridges to bulk carrier wharves

This presentation focuses on the journey from basic bridges and boardwalks through to the technological and design advances of fibre composite research and development.

Public building for post-disaster function

Not all public buildings are built for post-disaster function, but a majority of post-disaster function buildings are public infrastructure. Buildings of this nature are not constructed very often, but many local and state government bodies may have exposure to them, be it in a design, construction, maintenance, operational or asset management capacity. This presentation is a focus on the design considerations and outcomes involved with the delivery of a structure within a cyclonic wind region. Specifically, the increased scrutiny and consideration of effects applied when designing a post-disaster function structure to wind loadings imposed by high category cyclones, where the scope for design is often defined outside of the requirements of the Australian Standards.
