Engineering for submerged structures
Underwater civil engineering and construction
An underwater intervention begins with understanding the asset, access conditions and construction objectives. The scope may include surveys, intervention support and records of observed conditions. The responsible engineer defines methods, resources and acceptance criteria together with the client, based on the actual condition of the structure.
Applications
A scope tailored to your asset.
Feasibility, methods and required resources depend on the technical assessment of each project.
Concrete structures and foundations
Assessment of submerged structures to plan inspections and potential interventions. The extent of the work depends on the design, the condition of the component and available access.
Water intakes, outfalls and crossings
The scope may include checking accessible sections, documenting observed conditions and supporting interventions specified in the design, while considering interfaces with system operations.
Infrastructure construction support
Planning underwater activities alongside other construction disciplines, with interfaces, operational restrictions and inspection points defined before mobilization.
Traceability
Define the deliverables.
Documentation and acceptance criteria should be agreed in the technical proposal according to the nature of the intervention.
- Scope and work plan consistent with the design and available access.
- Records of observed conditions using the documentation methods specified in the contract.
- Report on completed activities and observed limitations.
- Closeout documentation and acceptance criteria agreed with the client.
Integrated management
Quality, safety and environmental responsibility.
Atlas holds ISO 9001, ISO 14001 and ISO 45001 certifications. View our certificates and Integrated Management System Policy.
Commercial diving planning takes NORMAM-222/DPC and operation-specific requirements into account.

Questions about underwater civil engineering.
What information helps define an underwater construction project?
Drawings, asset location, inspection history, intervention objectives and operational restrictions help assess the scope. A site visit or preliminary survey may be needed before a final proposal.
Can work take place while the asset remains in operation?
This depends on an assessment of asset conditions and activity risks. The responsible engineer and operator must define any shutdown, isolation or other measures before work begins.
What records can be included in the technical deliverables?
Depending on the contract, deliverables may include a work plan, visual records, activity descriptions and a closeout report. The format, responsibilities and acceptance criteria should be specified in the approved scope.
