A common mistake on overseas steel structure projects is treating logistics as a final step. The fabrication schedule is agreed, the shop drawings are approved, and someone reminds the team, six weeks before delivery, that the components have to get from a Chinese factory to a site in West Africa. By then the component sizes, the lifting sequence and the site laydown area are all fixed, and the transport plan has to bend around them. It does not have to be that way. Logistics planning should start before fabrication, not after.
When the fabrication yard finishes the last member, that is a milestone for the factory, not for the project. The steel still has to be packed, loaded, trucked to a port, wait for a vessel, cross the ocean, clear customs, be trucked inland, and unloaded onto a site that may not yet have the laydown space, the crane road or the ground bearing capacity to receive it. Projects that plan only around the fabrication date discover this gap at the worst possible time: when the steel is already on the water.
Most bolted space-frame members are tubular steel sections connected through spherical nodes. Their relatively compact cross-sections make them suitable for bundled packing. However, longer members, larger connection components and supporting steelwork still need to be checked against container dimensions, loading limits and the handling equipment available at both ends of the route. Depending on the cargo dimensions, weight and shipping route, the available options may include standard containers, open-top or flat-rack containers, break-bulk shipping and, where suitable, Ro-Ro services. For example, a beam longer than the internal length of a standard container may require a different loading arrangement. Depending on its dimensions and weight, a flat-rack container or break-bulk shipment may be considered. If transport limitations are identified early, the design team can assess whether the member dimensions or connection details need adjustment. Logistics input at the design stage avoids this.
Port conditions vary considerably across African destinations. At some terminals, congestion, limited heavy-lifting equipment or restrictions on handling oversized cargo can affect discharge schedules. These conditions should be checked with the shipping agent and local port operator before the cargo is dispatched. For oversized or heavy components, the discharge method and available handling equipment also need to be confirmed in advance. If discharge arrangements, required permits and inland transport have not been confirmed in advance, the cargo may face additional delays at the destination port. This can leave the site team waiting for materials that have already completed the sea journey. The schedule recovery usually happens by crashing the erection, which introduces its own risks.
Steel arrives in bundles, but the erection crew does not build the building bundle by bundle. The erection sequence depends on the structural system and the installation method. A space frame may be assembled member by member at height, divided into sections for lifting, or assembled at ground level before being lifted or slid into position. If the first shipment contains only purlins and the columns are on the third vessel, the crew is unpacking the wrong thing. Packing lists and shipping schedules should be tied to the erection sequence, not to the factory production order. That is a logistics decision, and it has to be made before fabrication starts, because it determines how the factory stages and packs the bundles.
Q: When in the project timeline should logistics planning begin?
A: At the same time as the structural design concept, not after the shop drawings. The transport route, the port capacity, the inland road limits and the site laydown area all constrain the component sizes and the delivery sequence. Leave them until fabrication is complete and the design has already made decisions that the transport network cannot absorb.
Q: Is logistics only the fabricator’s responsibility?
A: No. The fabricator can tell you what each bundle weighs and measures. The EPC contractor or the site team owns the port, the inland route, the laydown area and the erection sequence. Logistics planning is the interface between the two. It works best when both sides sit down before fabrication and agree on the delivery plan.
Steel fabrication is the visible part of a project, but it is not the part that decides the delivery date. The final delivery date depends on more than the factory completion schedule. Shipping arrangements, port handling, inland transport and the sequence of erection all need to be coordinated with the production plan. Reviewing these requirements before fabrication begins helps reduce avoidable delays and makes it easier for the site team to receive the components in the required order.
