BRIDGE & WHARF CONSTRUCTION

High-quality bridge and wharf construction across Australia’s waterways; Experience in marine infrastructure and tidal environments.
Polaris Marine Group is a trusted name in bridge and wharf construction, delivering complex marine infrastructure projects across Australia’s coastline, rivers, and waterways. With a deep understanding of tidal conditions, structural engineering, and environmental regulations, we build resilient and high-performance structures that meet the needs of transport networks, commercial operators, and public amenities. From piling and substructure installation through to decking and handrails, our team manages every aspect of the construction process with care and precision. We work with government authorities, developers, and private clients to deliver projects that are safe, functional, and built to last. Whether constructing a new vehicular bridge, ferry wharf, marina access point, or pedestrian connection, Polaris Marine Group combines civil and marine expertise to ensure seamless outcomes, even in the most demanding conditions.

Marine Bridge Construction

Bridge construction in marine or tidal environments presents a unique set of challenges. Fluctuating water levels, variable soil conditions, and complex access constraints require careful planning and specialist construction techniques. Polaris Marine Group has extensive experience in delivering bridge infrastructure over water, including road bridges, pedestrian walkways, and utility crossings. Our team provides end-to-end services—from site preparation and foundation piling to pier construction, deck installation, and finishing works. We use a wide range of construction plant and marine platforms, including jack-up barges, floating cranes, and custom scaffolding, to safely access the site and complete works efficiently. Our crew is skilled in working under live tidal conditions, coordinating around shipping channels, and delivering to tight deadlines with minimal environmental impact. Our bridge projects often involve staged delivery to maintain public or operational access. We manage this complexity through detailed staging plans, stakeholder communication, and a commitment to safety and quality throughout.

Wharf Construction & Redevelopment

Wharves are vital pieces of marine infrastructure, serving as access points for transport, logistics, tourism, and recreation. Whether a project involves building a new wharf or refurbishing an existing structure, Polaris Marine Group brings decades of experience and proven capability. We construct all forms of wharf infrastructure, including public ferry terminals, commercial loading platforms, marina berths, and service jetties. Our work ranges from small-scale foreshore access structures to large commercial facilities with heavy load-bearing capacity. Every wharf we build is engineered to suit the unique site conditions and operational needs. We take into account tidal ranges, vessel types, environmental factors, and regulatory requirements. Our services include piling, deck fabrication, fender system installation, gangways, lighting, handrails, and safety infrastructure. We also provide condition assessments and remediation services for ageing or damaged wharves. Our team can extend the life of existing structures by strengthening foundations, replacing corroded components, or upgrading surface finishes to meet modern codes.

Integrated Design and Construction

Polaris Marine Group often works under design-and-construct or early contractor involvement (ECI) models. These arrangements allow us to contribute our marine construction expertise during the planning phase, reducing risk, saving time, and delivering more cost-effective outcomes. We collaborate closely with engineers, architects, and stakeholders to refine construction methodology, optimise structural design, and identify logistical efficiencies. Our input helps shape bridges and wharves that are easier to build, more durable in marine environments, and aligned with the project’s environmental and aesthetic objectives. By managing both the design and construction, we take full responsibility for safety, quality, and performance from start to finish.

Specialist Marine Equipment and Personnel

Bridge and wharf construction requires specialist knowledge and equipment—both of which Polaris Marine Group provides in-house. Our fleet includes piling barges, floating cranes, workboats, jack-up platforms, and low-impact access systems. These assets allow us to work efficiently in difficult marine environments, including shallow tidal flats, busy ports, and remote locations. Our construction crews are made up of highly trained marine workers, welders, riggers, divers, and project managers. They are supported by a team of experienced civil and structural engineers who oversee project execution and ensure compliance with Australian standards. We also maintain ISO-certified systems for safety, quality, and environmental management, ensuring our projects meet the highest levels of professionalism and regulatory compliance.

Environmental and Community Considerations

Polaris Marine Group takes pride in its ability to deliver marine infrastructure while protecting surrounding ecosystems and minimising disruption to local communities. We develop site-specific environmental management plans for every project, addressing potential impacts on water quality, marine life, vegetation, and sediment movement. Our team uses low-vibration piling techniques where possible, times construction to avoid sensitive breeding or migration periods, and applies sediment controls to prevent runoff during works. We also ensure waste management, noise control, and marine traffic coordination are part of our daily site operations. Where projects are located in public areas, we engage with local stakeholders to keep them informed and ensure safe pedestrian and recreational access throughout construction.

Proven Experience Across All Project Sizes

Polaris Marine Group has delivered marine bridge and wharf projects of all sizes—from small jetty upgrades to major transport infrastructure. Our clients include local councils, state transport authorities, developers, port operators, and maritime businesses. We have worked in regional areas, urban environments, heritage locations, and sensitive ecological zones. Across all projects, our focus remains the same: deliver durable, well-designed marine infrastructure that performs reliably for decades. With the skills, resources, and marine construction expertise to deliver in full and on time, Polaris Marine Group is the partner of choice for bridge and wharf construction across Australia’s waterways.
