Maritime constructions
New waterfront structures need eyes and hands below the surface throughout construction: checking pile positions, guiding elements into place and confirming that the finished work matches the drawings.

In detail
On a waterfront construction site, everything above water is visible and measurable — and everything below it is taken on trust unless somebody goes down to look. Pile positions, verticality, bedding layers, scour at freshly driven sections, the seating of a precast element: each one is a hold point that can quietly cost weeks if it is discovered late.
We act as the underwater extension of the site team. That means attending planning meetings, working inside the contractor's permit and SIMOPS regime, being available on the days piling or lifting is scheduled, and delivering a same-day record of what was checked. Because the diver is on the programme rather than called in afterwards, problems surface while they are still cheap to solve.
At the end of the works the same team produces the underwater part of the as-built record: measured positions, levels, photos and video of the completed structure. For jetties, dolphins, mooring facilities and berth pockets that record is what the future asset manager will inspect against for the next twenty years.
What you receive
- Diver attendance planned into the construction programme

Working method
We integrate into the contractor's programme, attending planning meetings and working to the site's permit system. Each underwater hold point is recorded so the main contractor can sign off progress with evidence.
Equipment and techniques
- Survey and levelling aids
- Surface-supplied diving systems
- Video and stills recording
- Hydraulic tooling
Safety considerations
- Interface control with piling and crane work
- Simultaneous operations planning
- Emergency stop and recall signals
- Daily toolbox talks with the site team
