Marine Pontoons

Marine Pontoon Design & Construction

Our engineering team provides construction inspection, design, and certification for all components of pontoons and jetties across local authorities including Gold Coast City Council, Logan City Council, Tweed Shire Council, Brisbane City Council, Moreton Bay Regional Council, Sunshine Coast Regional Council, Ipswich City Council, and other regions in Northern New South Wales and Queensland. All works are certified by an RPEQ engineer and include:

  • Marine piling
  • Underwater structural formwork erection and temporary works installation
  • Underwater welding and cutting
  • In-situ concrete works
  • Precast concrete elements
  • Structural framing (beams, columns, etc.)
  • Steel and timber framing
  • Footings and foundations
  • Landing decks
  • Fixtures and corrosion condition assessments
  • Embankments and retaining walls
  • Complete structural systems

Our team ensures all marine structures are designed and constructed to meet relevant standards, durability requirements, and environmental considerations, delivering safe and long-lasting outcomes for coastal and inland waterway infrastructure.

What We Bring to the Job

  • Barge & Workboat — A dedicated work barge and support vessel used to transport materials, equipment, and personnel to marine construction sites — including sites inaccessible from land.
  • Hydraulic Pile Driving Equipment — Hydraulic impact and vibratory pile drivers for the installation of steel and timber piles in a range of seabed conditions, including sand, clay, and rock.
  • Marine Crane — A marine-mounted crane for the precision lifting and placement of pontoon floats, gangway structures, and heavy marine components in open water.
  • Dive Support — Qualified commercial divers supporting underwater pile inspection, seabed assessment, and subsurface connection works.
  • Aluminium Fabrication Capability — In-house and contracted aluminium fabrication for pontoon frames, gangway structures, and handrail systems — using marine-grade alloys suited to saltwater exposure.
  • Structural Design Software — Marine structure modelling and analysis software used by our engineers to verify buoyancy, structural capacity, and dynamic loading under real-world wave and tidal conditions.

Our 3-Step Project Process

Water infrastructure must be designed accurately, built precisely, and tested thoroughly. Our process ensures the system works before we leave the site.

Site Assessment & Engineering Design

We begin with a full site survey  bathymetry, tidal data, wave exposure, and seabed investigation. Our engineers use this data to develop a detailed design including pontoon sizing, pile layout, gangway geometry, and mooring specifications.

Fabrication, Procurement & Mobilisation

Structural components are fabricated or procured to specification while we coordinate all required maritime permits and approvals. Our marine construction team and equipment mobilise to site once the design is approved and all materials are ready.

Marine Construction & Commissioning

Construction is carried out from our work barge, with all works timed around tidal windows and weather conditions
