Bridge Construction and Maintenance Over Water in WA — Rescue Vessel Requirements
Bridge construction and maintenance is one of the most common over-water work activities in Western Australia. From major river crossings on regional highways to bridge maintenance works in urban and port environments, project teams working on bridge structures over water face a consistent set of water safety obligations that must be addressed in their safety planning.
For project managers and HSE teams planning bridge construction or maintenance in WA, understanding the rescue vessel requirements that apply to your project is essential.
The water safety risks of bridge construction and maintenance
Bridge construction and maintenance over water presents a specific set of hazards that must be addressed in the project safety plan:
Workers at height on bridge structures are directly over water for extended periods
Falls from bridge structures can result in entry into fast-moving river currents or tidal waterways
Access to a casualty in the water from a bridge deck or bank can be extremely difficult without a vessel
Bridge construction environments often involve confined spaces under the bridge deck where conventional rescue boats cannot operate
Multiple trades working simultaneously on a bridge structure increases the probability of a fall-into-water incident
What WA legislation requires
Under the WA Work Health and Safety Act 2020, PCBUs conducting bridge construction or maintenance over water must eliminate or minimise risks to workers so far as is reasonably practicable. For bridge projects, this means having a documented rescue plan that specifically addresses fall-into-water scenarios, appropriate rescue equipment, and qualified rescue personnel available for the duration of the works.
A bridge construction safety plan that addresses fall arrest and working at height but does not cover the water rescue component does not satisfy WA legislative requirements.
Why a PWC rescue vessel is suited to bridge construction environments
Bridge construction and maintenance environments present specific challenges for rescue vessel operators. The confined space under a bridge deck, the presence of bridge piers and abutments, and the potential for fast-moving water in river environments all require a vessel that is highly manoeuvrable and able to operate in shallow and confined conditions.
A PWC rescue vessel is well suited to these environments. It can operate effectively under low bridge clearances and around bridge piers, manoeuvre quickly in fast-moving river currents, reach a casualty in the water within seconds, and recover them onto the rescue sled without the rescuer needing to enter the water.
Common bridge projects in WA requiring standby rescue vessel services
Some of the most common bridge construction and maintenance projects in Western Australia that require standby rescue vessel services include:
New bridge construction over rivers and tidal waterways on regional and metropolitan road networks
Bridge deck replacement and structural maintenance works
Bridge inspection and underwater assessment works
Piling and substructure works for bridge construction and maintenance
Temporary bridge and bailey bridge installation over waterways on mine site haul roads and access roads
Hardy Seas and bridge projects
Hardy Seas provides standby rescue vessel services for bridge construction and maintenance projects across Western Australia. We have experience working in river, tidal, and inland waterway environments and can mobilise to bridge project sites anywhere in the state — including remote locations via our 20ft sea container mobilisation model.
Our crews work directly with bridge construction project teams and HSE managers to develop a site-specific rescue plan, conduct mock rescue drills with site personnel, and maintain full compliance documentation throughout the project duration.
Get in touch
If you are planning bridge construction or maintenance over water in Western Australia, get in touch with Hardy Seas to discuss your rescue vessel requirements. We can advise on mobilisation logistics, crew requirements, and compliance documentation for your specific project.
