Commercial diving for infrastructure and tender projects

Capability information for government, asset owners and Tier 1 procurement teams.

Commercial Diving Services (CDS), Australia, provides underwater inspections, maintenance and construction for marine and inland assets. This page brings together the service scope, company systems and project evidence to help procurement teams prepare a commercial diving enquiry.

Match the diving scope to your asset

Infrastructure inspections

Review bridge inspections and maintenance, dam inspections and maintenance, and the wider inland diving service range.

Underwater construction and maintenance

Explore underwater maintenance and construction for works such as cutting, welding, drilling, core sampling and concreting. Include drawings, asset condition and access constraints in the project brief.

Vessels and port operations

The commercial shipping hub brings together class surveys, hull inspections, biosecurity, propeller work and anchor maintenance.

Equipment and mobilisation

CDS describes modular diving equipment for local, national and international mobilisation, with vessels, barges, ROV systems and underwater photo and video equipment. See company capability and marine equipment.

Safety, quality and environmental documentation

CDS publishes an integrated management approach covering quality, environmental and safety systems. Start with the workplace health and safety policy, quality policy, environmental policy and continual improvement policy.

For tender assessment, request the current certificates, insurance evidence, personnel competencies and project-specific documentation required by your organisation. Confirm their scope and validity against the proposed works; this overview does not replace supplier prequalification.
