How to plan procurement for a project in Guinea or Sierra Leone: what to buy locally, what to import, lead times, documentation, packing, port clearance and the errors that stop a site.
On a domestic project, procurement is a support function. On a cross-border project it is the schedule. A structure cannot rise ahead of its reinforcement, a facade cannot be installed before the glass clears customs, and a building cannot be commissioned without switchgear that spent eleven weeks at sea. Most projects that fall behind in this region fall behind here, not on site.
This guide covers how to plan it.
The first procurement document is not a purchase order but a list: every significant package, marked local or imported, with the reason.
Typically available locally, subject to verification: sand, aggregate, blockwork, some cement, timber for formwork, common labour, basic ironmongery.
Typically imported: structural steel, reinforcement to a specified grade, waterproofing systems, lifts, chillers and air-conditioning equipment, switchgear and cabling to standard, curtain walling, ceramic and stone finishes, sanitaryware, door and window systems, fire detection and suppression.
The list is project-specific and must be verified rather than assumed — availability and quality vary by country and by year. Verification means sampling and testing, not a supplier's assurance.
For every imported package, the lead time is a chain:
1. Design and approval of shop drawings
2. Manufacturing
3. Inland transport to the port of loading
4. Sea freight
5. Discharge and port clearance at destination
6. Inland transport to site
Only the second and fourth are usually estimated. The others regularly consume as much time again. The date that matters is not the order date but the *required-on-site* date minus the whole chain, plus a margin for the rainy season if the delivery crosses it.
Long-lead items — lifts, chillers, switchgear, curtain wall, bespoke steel — should be ordered on the strength of the programme, sometimes before the related design is fully complete, with the specification frozen for the parts that drive manufacturing.
Clearance delays are rarely caused by the goods. They are caused by paperwork that does not match the goods: a packing list that disagrees with the invoice, an HS code that invites reclassification, a certificate of origin missing a stamp, or a description too vague to assess.
Practices that shorten clearance:
Working with a broker who already handles construction cargo for the destination port is worth more than a marginally cheaper freight rate.
Goods travel by sea through humid air, then wait in an open yard. Packing should assume both:
Steel that arrives with damaged coating, or switchgear that arrives damp, converts a procurement saving into a site problem.
Fewer, fuller containers cost less per unit and clear faster than many part loads. Consolidation requires ordering discipline: packages grouped by required date, and suppliers held to a common readiness date.
Sequencing matters as much as consolidation. Materials that arrive too early occupy storage, tie up capital and deteriorate; materials that arrive late stop work. The procurement schedule should be reviewed against site progress at least monthly.
Certain items justify holding stock: reinforcement couplers, fixings, waterproofing consumables, spare glazing panels, common electrical components. The cost of holding them is small; the cost of a two-month wait for a small item that blocks a large activity is not.
Inspecting on arrival is too late — rejected material at destination means the lead time starts again. Where the value justifies it, inspect at the factory before shipment: dimensional checks on fabricated steel, coating thickness, test certificates for reinforcement and cement, factory acceptance tests for major equipment. A day of inspection at origin routinely saves months.
It depends on the specification, but structural steel, quality reinforcement, mechanical and electrical equipment, lifts, facade systems and higher-grade finishes are commonly imported, while sand, aggregate, blockwork and much of the labour are local. The split should be verified project by project.
Order against the programme rather than site progress, allowing for design approval, manufacturing, freight, clearance and inland transport together. For major equipment this often means placing orders in the earliest months of the project.
Documentation inconsistencies and incomplete certificates, not shipping itself. Agreeing descriptions, codes and certificates with the customs broker before the container is loaded removes most of the risk.
Buying through a contractor that already imports into the destination country transfers the logistics risk and usually clears faster. Direct purchase can look cheaper on the invoice while leaving the employer holding demurrage, clearance and schedule risk.
