Start Project BriefDevelopment & Humanitarian Infrastructure · Island logistics
Factory price is only one part of an island project. Small trade volumes, shipping connectivity, container utilisation, port handling, inland access, lifting, storage and local labour can materially affect the delivered cost of modular buildings. The right comparison is total project logistics, not the ex-factory unit price alone.
UN Trade and Development's 2024 global transport-cost work reported that small island developing states face the highest transport and insurance costs relative to import expenditure. Low trade volumes, remoteness and limited shipping connectivity can reduce economies of scale.
This does not mean every island route is expensive in the same way; route, season, carrier, cargo format and port all matter.
Compare how many complete dwellings or building modules fit into each container, not just the dimensions of one unit. A wider or more complete module may reduce site labour but use more freight volume, while a flatter pack may improve shipping efficiency but shift more work to the destination.
Add customs or import processes, port handling, container detention or storage risk, onward trucking or ferry movement, difficult road access, unloading equipment and site laydown. The last leg can dominate delivery complexity on smaller islands.
A highly compact flat-pack system can be attractive where trained local assembly capacity is available. Where specialist labour or equipment is scarce, a more factory-complete system may reduce local construction risk even if freight utilisation is lower.
Large programmes should coordinate manufacturing, vessel schedules, port storage, foundations, unloading equipment and assembly capacity. Shipping too much too early can create storage and demurrage exposure; shipping too slowly can leave site crews waiting.
Comparison reference
| Planning criterion | Cost / risk layer | What to check |
|---|---|---|
| Factory packing | Units per container, package dimensions, weights, loading method | |
| Ocean freight | Route frequency, container type, seasonal rate exposure, trans-shipment | |
| Port / import | Handling, customs, free time, storage, importer responsibilities | |
| Onward transport | Truck, ferry, bridge, corner, road width / weight limits | |
| Site receiving | Crane / forklift, laydown, weather protection, package inspection | |
| Assembly | Local labour, supervision, tools, temporary works, service connections |
Freight rates are volatile. Project comparisons should use current route-specific quotations and confirmed package data rather than historic headline rates.
