For coastal revetments, the quarry is part of the job

Ebeye begins at a quarry in Ras Al Khaimah

Ebeye's new ocean-side seawall starts far from the Marshall Islands. Bontrup says approximately 80,000 tonnes of armourstone, graded up to 3/6 tonnes, came from Stevin Rock in Ras Al Khaimah. The Bontrup Pearl carried it for about 30 days before transferring the cargo in deep water to barges for the final trip ashore.

That supply figure is larger than the roughly 65,000 tonnes of armour rock described by Hall Contracting and Haskoning for 1.81 kilometres of new revetment. It is also different from the World Bank's 2.1-kilometre results target, which includes 300 metres of existing seawall. Cargo supplied, rock designed for placement and coastline counted under a programme indicator are three separate quantities.

The barge transfer and dedicated unloading facility prove that the marine logistics chain is working. They do not establish how much stone has passed inspection, reached its final chainage or been accepted in the toe, filter and armour profile. Those answers require quarry releases, landing records, placed quantities, surveys and owner sign-off.

Goree's stone supply has already moved the programme

On Goree Island, the June 2026 World Bank financing paper records seven months of early delay in rock supply. It reports coastal protection at 85 percent, or 75 percent when landscaping is included, and seeks EUR 3.5 million of additional credit with a proposed closing date of 30 June 2027. A WACA update used an earlier boundary: 82 percent overall completion at 31 March 2026.

The remaining package is more than a final volume of rock. It includes eastern and western dike sections, six breakwaters, work beside the Mariama Ba school, stabilisation near the mosque, promenade and landscaping interfaces, and heritage approvals. Rough sea conditions, island logistics and UNESCO requirements continue after the quarry bottleneck has eased.

Progress percentages therefore need their measurement date and scope beside them. The protection-only figure cannot be exchanged for the figure that includes landscaping, and neither replaces surveyed geometry, environmental close-out or owner acceptance.

West Point has a permit but no works award

Liberia's Environmental Protection Agency authorised the West Point revetment in March 2026 within defined project coordinates. The wider Monrovia climate-resilience programme has Green Climate Fund and government financing, and the UNDP project page records the government's in-kind contribution in rocks. The construction contractor, executed revetment value, notice to proceed and mobilisation date are not disclosed.

The conceptual design already makes the material questions concrete. It describes a rubble-mound revetment, different armour needs along the shoreline, a geotextile toe, a promenade and boat launching and landing points. Procurement still has to turn that concept into approved quarry sources, grading, quantities, haulage, stock control, inspection duties and a buildable community-access plan.

The environmental permit is a real milestone because it fixes the authorised footprint and conditions. It does not answer who carries rock-supply risk, how the in-kind contribution will be valued and reconciled, or when the shoreline work will begin.

Completion sits at the end of the material ledger

Ebeye has an operating quarry-to-barge chain but still needs accepted placement records. Goree is well into construction, yet finance, remaining interfaces and handover remain open. West Point has an environmental permit but no evidenced construction award. Calling all three simply 'coastal protection projects' hides the decisions that now matter.

A complete revetment file has to reconcile approved source and grading, shipped and landed cargo, accepted placed quantities, surveyed profiles and chainages, tie-ins, drainage, access restoration and maintenance responsibility. When those records do not reconcile, a ship full of stone, a high progress percentage or a permit can each be accurate without proving a finished coastal defence.
