ENVIRONMENTAL SOLUTIONS

Polaris Marine Group delivers practical environmental solutions for marine and coastal construction, ensuring sustainability and performance.
Environmental Marine Solutions
At Polaris Marine Group, delivering sustainable outcomes isn’t an afterthought—it’s part of how we operate every day. Our environmental solutions are purpose-built for marine and coastal infrastructure projects, supporting both the immediate needs of our clients and the long-term health of the environments we work in. Whether we’re managing sediment control, protecting marine habitats, or ensuring water quality compliance, Polaris brings a practical, outcomes-driven approach to environmental management.

Project Summary

Key Achievements

Integrating Sustainability into Every Project

Environmental performance is a critical consideration across all marine construction activities, and we treat it as a core discipline, not a compliance checkbox. Our in-house team collaborates with environmental consultants, regulators, and project managers from the earliest stages of project development. This ensures that environmental risks are identified early and addressed through design, methodology, and real-time monitoring. From working in ecologically sensitive estuaries to delivering capital dredging campaigns in regulated waterways, our environmental solutions are integrated into project planning and execution. This includes developing Environmental Management Plans (EMPs), liaising with approval bodies, and implementing on-site controls that reduce impact while maintaining construction efficiency.

Sediment and Water Quality Management

One of the most critical environmental risks in marine construction is the disturbance and migration of sediments. Polaris Marine Group uses a range of field-tested strategies to manage this risk, including silt curtains, bund containment, and low-impact dredging methods. We also provide real-time water quality monitoring and reporting to ensure compliance with relevant guidelines and permits. Our work in this space often supports larger objectives—like habitat protection, coastal resilience, or stormwater improvement. By managing turbidity, sediment dispersion, and contaminant movement, we help project stakeholders maintain environmental licences and build trust with surrounding communities and regulators.

Marine Fauna Protection Measures

Polaris Marine Group implements proven measures to protect marine fauna during construction activities. These range from soft-start procedures during piling operations to the use of bubble curtains, exclusion zones, and on-site fauna observers. We maintain strong relationships with environmental specialists who support our teams on the ground, providing risk assessments and mitigation strategies that align with best-practice environmental guidelines. Our crews are also trained to identify, report, and respond to the presence of protected species. Whether it’s dolphins, turtles, or migratory birds, we take every precaution to avoid harm to wildlife and to ensure our clients’ projects proceed responsibly and without incident.

Contaminated Material Management

In some marine zones, sediment contamination from historical land use or industrial activity presents a major risk. Polaris Marine Group has the expertise to handle these sensitive situations. We carry out sediment sampling, coordinate with accredited laboratories, and develop safe methods of removal, containment, or relocation. In every case, our goal is to minimise environmental impact while meeting the objectives of the project. Our environmental solutions include the safe disposal of contaminated dredge material in accordance with EPA regulations, as well as bund construction, barge transport, and treatment coordination when required. We also work closely with clients to provide documentation and records that support due diligence and environmental auditing.

Erosion Control and Shoreline Stabilisation

Marine and coastal construction frequently involves working in areas where shorelines are exposed to erosion and instability. Polaris Marine Group offers a range of environmentally conscious stabilisation techniques, including rock revetments, bioengineering, and sediment rebalancing. These measures help to preserve shorelines, protect infrastructure, and maintain the natural movement of water and sand in estuarine systems. We work in partnership with coastal engineers and landscape consultants to develop solutions that balance structural performance with environmental integrity. This includes careful planning of access points, staging areas, and traffic management to reduce soil compaction, vegetation loss, and habitat disruption.

Supporting Long-Term Environmental Outcomes

While many contractors deliver environmental controls during construction, Polaris Marine Group remains focused on post-project success. We support monitoring programs, habitat reinstatement, and adaptive management where ongoing intervention is required. Our environmental solutions are designed to create measurable improvements, not just meet temporary thresholds. In collaboration with marine scientists and restoration experts, we have delivered seagrass protection strategies, mangrove rehabilitation programs, and reef-friendly mooring solutions. We believe marine infrastructure should serve communities for decades, and that includes the natural systems that surround it.

Proven Experience in Environmentally Regulated Zones

From harbours and ports to river crossings and coastal developments, Polaris has worked across some of Australia’s most environmentally sensitive zones. Our team is familiar with the unique approval pathways, risk factors, and public expectations that come with operating in these areas. We’ve successfully delivered projects under strict EPA and DCCEEW conditions, supported major infrastructure upgrades with environmental compliance at the forefront, and managed stakeholder engagement where environmental concerns are high. This depth of experience ensures our clients feel confident when navigating complex regulatory environments.

PROJECTS

SEE US IN ACTION

Manton Dam

Polaris Marine Constructions were engaged by Exact Contracting to provide a modular crane barge service at the Dam wall at Manton Dam to deliver the replacement of internal valving and upgrades to the infrastructure of the Intake tower.

Nelligen Bridge Marine Support and Demolition Contract

Polaris Marine Group played a key role in the Nelligen Bridge project, providing overwater support for construction before demolishing the 7-span, 5,000-tonne bridge. The in-house demolition was incident-free, using a suspended work deck with geotextile and drainage to capture debris. Materials were processed on-site and recycled. This project highlighted Polaris Marine’s expertise in complex marine demolition within sensitive waterways.

Seabed Services Pipe Line Deployment

Deploy 3 service pipe lines on the sea floor between Garden Island and Fort Dennison and cover with precast grout mattresses.

Fort Denison – Ferry Wharf

This project included wharf demolition, sea wall remediation, pile installation, concrete works, and the installation of a new pontoon with electrical connections.

Circular Quay – Western Promenade – Soffit Concrete Repairs

This project involved concrete remediation works, including hydro-blasting, shotcrete application, bar reinforcement, protective coatings, and concrete cutting, with site set-up, exclusion zones, and sound curtain installation to ensure safety and minimal disruption.

Manly Boat Shed – Pontoon & Jetty Replacement

This project involved constructing a pontoon, gangway, and timber jetty, including piling, demolition, and electrical connections, to deliver a durable marine access solution.

“The attention to detail provided by PMC during the project could not be faulted. Execution, safety, onsite management and the finished product were at a very high standard. Communication throughout the project from PMC Supervisors and Project Manager were regular and accurate. This enabled Thales to understand daily activities, problems and overall progression at every stage. Ultimately, the professionalism shown by PMC through all aspects of the project, enabled for a successful end product to the Commonwealth. I can’t thank Dane and the PMC team enough for the way the project was ran, start to finish.”
