Coastal Public Infrastructure Upgrade in Quinns Rocks
Alldin delivered the Queenscliff Park Boardwalk and Pergola Upgrade in Quinns Rocks for the City of Wanneroo, replacing deteriorated coastal timber structures with a durable, low-maintenance public infrastructure solution.
Designed for a harsh marine environment, the upgrade incorporated recycled plastic and composite fibre materials selected for long-term performance, corrosion resistance and reduced maintenance.
The completed works enhance the coastal public space with a curved boardwalk that frames the ocean outlook and a contemporary pergola that adds shade, structure and architectural definition.

Coastal Public Infrastructure Upgrade in Quinns Rocks
Alldin delivered the Queenscliff Park Boardwalk and Pergola Upgrade in Quinns Rocks for the City of Wanneroo, transforming deteriorated coastal timber structures into a durable, low-maintenance and visually refined public space designed for long-term performance.
Located in a harsh marine environment, the existing boardwalk and pergola had been impacted by salt spray, coastal humidity and general weathering. The project required more than a like-for-like replacement, it called for a smarter public asset renewal solution that could withstand the coastal conditions while improving the safety, usability and presentation of the park.
The completed works now provide the community with a stronger, more contemporary civic space, featuring a curved recycled-plastic boardwalk that frames the ocean outlook and a modern pergola structure that adds shade, rhythm and architectural definition.
Scope of Work
Alldin delivered the demolition and renewal of the Queenscliff Park boardwalk and pergola, including site preparation, structural works, recycled plastic decking, guardrails, pergola screening, compliance documentation and final handover.
Alldin’s scope included:
- Site establishment, temporary fencing, signage, tree protection and site management
- Survey, set-out, service location and potholing
- Demolition and disposal of the existing boardwalk and pergola structures
- Preparation of management plans, including quality, environmental, safety and traffic requirements
- Building permit coordination, including Certificate of Design Compliance
- Shop drawings and engineering certification
- Supply and installation of new structural members, including footings
- Installation of recycled plastic boardwalk decking
- Installation of recycled plastic triple-rail guardrail and 125mm square posts
- Pergola structural renewal, including new structural members and associated footings
- Installation of recycled plastic screening to pergola structures
- Site cleaning, demobilisation and handover
- QA documentation, engineer inspection/sign-off, Certificate of Construction Compliance, as-constructed drawings and ASPEC documentation
Alldin was engaged to deliver the Queenscliff Park Boardwalk and Pergola Upgrade in Quinns Rocks, renewing the existing coastal structures with more durable, low-maintenance materials suited to the harsh marine environment.
Construction in a Live Public Environment
Public infrastructure upgrades require more than construction skill. They demand strong site coordination, clear communication, public safety planning and careful management of surrounding assets.
The technical specification required the contractor to submit a project management plan covering work methodologies, staging, public safety strategies and access restrictions. It also required noticeboards to be installed before works commenced, outlining the extent of works, expected timeframe and supervising engineer contact details for the surrounding community.
This level of planning is critical for civic infrastructure projects where works are delivered in community spaces. Alldin’s delivery approach needed to account for public access, existing vegetation, adjacent infrastructure, safety barriers, retained works and site presentation throughout the construction period.
Composite Fibre Technology for Long-Term Durability
The project also used Wagners Composite Fibre Technologies for key structural elements. Wagners CFT materials were specified for columns, structural framework and bearers, providing a strong alternative to traditional timber in a coastal environment.
Fibre Reinforced Polymer materials offer high strength, low weight and long service life, while avoiding common issues associated with timber and steel, such as rot, corrosion and shrinkage. The Wagners proposal also highlights the material’s low-maintenance qualities and 75–100 year lifecycle potential, making it well suited to public infrastructure exposed to challenging environmental conditions.
For local government construction projects, this type of material selection is important because it supports long-term asset value, reduces maintenance requirements and helps minimise future disruption to the public.
Designed for Coastal Longevity
In marine environments, material selection is critical. Salt spray, moisture, humidity and constant exposure can quickly reduce the lifespan of traditional timber structures. The Queenscliff Park upgrade directly responded to these conditions by replacing deteriorated timber elements with recycled plastic and composite fibre materials selected for corrosion resistance, durability and low maintenance.
This makes the project a strong example for councils, developers and asset owners looking to upgrade coastal public infrastructure with a focus on long-term performance.
Low-Maintenance Public Infrastructure
The project was designed with whole-of-life asset value in mind. By using materials that resist rot, corrosion, decay and weathering, the upgraded boardwalk and pergola are better positioned to remain safe, functional and visually consistent over time.
For local government and public works teams, this reduces the burden of ongoing repairs and helps create infrastructure that can serve the community for longer with less disruption.
Alldin delivered a durable and visually refined coastal public infrastructure upgrade that renewed ageing timber structures, improved the usability of Queenscliff Park and introduced long-life materials suited to the marine environment.
The project reflects Alldin’s capability as a council project contractor in Perth, with experience delivering civil infrastructure upgrades, public asset renewal, community infrastructure upgrades and local government construction projects across WA.
Planning a Public Infrastructure Upgrade in Perth?
Alldin delivers durable, low-maintenance public spaces that respond to their environment, perform long term and enhance the way communities use them. The Queenscliff Park Boardwalk and Pergola Upgrade reflects this approach, transforming deteriorated coastal structures into a refined public asset built for the harsh marine environment.
