Introduction to African Development Bank Procurement
The African Development Bank (AfDB) is the premier multilateral development finance institution for the African continent, financing projects worth billions of dollars annually across infrastructure, energy, agriculture, health, education, and governance. For suppliers, consultants, and contractors seeking to work on African development projects, understanding AfDB procurement rules is essential — these rules govern how project funds are spent and who can compete for contracts.
AfDB procurement operates under the Bank Procurement Policy for Bank Group Funded Operations, which was significantly updated in 2015. The policy balances several objectives: economy and efficiency, giving all eligible bidders a fair opportunity to compete, encouraging the development of domestic contracting and manufacturing industries in borrowing countries, and ensuring transparency in the procurement process.
Procurement Methods for Goods and Works
International Competitive Bidding (ICB)
ICB is the default procurement method for high-value contracts. It involves international advertising, standardised bidding documents, and evaluation criteria that are published in advance. ICB is required when the estimated contract value exceeds thresholds set in the project procurement plan — typically $5 million or more for works and $500,000 or more for goods, though thresholds vary by country and project.
The ICB process follows a defined sequence: the borrower publishes an invitation to bid in widely circulated media and on the AfDB procurement portal, bidders purchase or download bidding documents, a pre-bid meeting or site visit may be held, bids are submitted by the deadline and opened publicly, evaluation is conducted strictly against the criteria stated in the bidding documents, and the contract is awarded to the lowest evaluated substantially responsive bidder. The entire process typically takes 3-6 months from advertisement to contract award.
National Competitive Bidding (NCB)
NCB is used for contracts that, by their nature or scope, are unlikely to attract international competition — typically lower-value contracts or those requiring local knowledge and presence. NCB follows the borrowing country national procurement procedures, provided these are acceptable to the Bank and consistent with its procurement policy. Thresholds for NCB are set in each project procurement plan.
While NCB uses national procedures, the AfDB reviews the process to ensure it meets minimum standards of competition, transparency, and fairness. International suppliers are not excluded from NCB procurements, but the advertising and documentation requirements may be less extensive than ICB.
Shopping
Shopping is a simplified procurement method for low-value, readily available goods or simple works. The borrower obtains price quotations from at least three qualified suppliers, compares them, and awards to the lowest priced offer meeting the specifications. Shopping is typically used for contracts below $100,000 for goods and $200,000 for works, depending on the project procurement plan.
Direct Contracting
Direct contracting (single-source procurement) is permitted only in exceptional circumstances: when only one supplier can provide the required goods or services (genuine monopoly), for standardisation or compatibility with existing equipment, in urgent situations requiring immediate action, or for follow-on contracts where the original supplier has satisfactory performance and competitive pricing. The AfDB must approve all direct contracting above specified thresholds.
Consulting Selection Methods
The AfDB uses distinct methods for selecting consultants (firms and individuals), recognising that consulting services require evaluation of quality alongside price.
Quality and Cost-Based Selection (QCBS)
QCBS is the default method for most consulting assignments. The process involves: publication of an Expression of Interest (EOI), shortlisting of 4-6 firms based on their qualifications, issuance of a Request for Proposals (RFP), submission of technical and financial proposals in separate sealed envelopes, evaluation of technical proposals against published criteria (methodology, key personnel, experience), opening of financial proposals only for technically qualified firms (those scoring above a minimum technical threshold, typically 70-80 points), and combined ranking using a weighted formula (typically 70-80% technical, 20-30% financial). The firm with the highest combined score is invited to negotiate and execute the contract.
Quality-Based Selection (QBS)
QBS is used for complex assignments where the quality of the consulting service is paramount and the scope of work is difficult to define precisely. Under QBS, only technical quality is evaluated — financial proposals are opened only for the top-ranked firm, and negotiations focus on the scope, methodology, and price. QBS is typically reserved for highly specialised assignments such as country strategy development, complex feasibility studies, or assignments with significant downstream impact.
Consultant Qualifications Selection (CQS)
CQS is a simplified method used for small, straightforward assignments (typically below $200,000). The borrower requests expressions of interest, evaluates the qualifications of responding firms, selects the most qualified firm, and negotiates the contract directly. This method avoids the full proposal submission process and is suitable for assignments where the differences between qualified firms are minimal.
Other Methods
Additional consulting selection methods include: Least Cost Selection (LCS), used for standard assignments where methodology is well-established; Fixed Budget Selection (FBS), where firms compete on quality within a disclosed budget; and Selection of Individual Consultants (IC), used for assignments where a team is not required and individual expertise is sufficient.
Eligibility Rules
AfDB procurement is open to firms and individuals from all countries, subject to specific exclusion criteria. A firm or individual is ineligible if: it is from a country that is not a member of the AfDB Group, it has been sanctioned by the AfDB under its sanctions framework (for fraud, corruption, collusion, coercion, or obstruction), it is subject to United Nations sanctions, or it has a conflict of interest with respect to the specific procurement (such as having provided consulting services that influenced the specifications).
Unlike some development banks, the AfDB does not restrict eligibility based on the source country for most procurement — the Bank policy emphasises broad international competition. However, domestic preference margins may apply for ICB contracts for goods (typically a 15% preference for domestically manufactured goods) and for works (where domestic contractors may receive a preference margin).
Registration and Finding Opportunities
The AfDB publishes all procurement opportunities on its website (www.afdb.org) under the Projects and Operations section. General Procurement Notices (GPNs) are published when a new project is approved, alerting suppliers to upcoming procurement under the project. Specific Procurement Notices (SPNs) — invitations to bid or expressions of interest — are published when individual procurements are launched.
Suppliers should register on the AfDB procurement portal and sign up for email alerts in their sectors and geographies of interest. The United Nations Development Business (UNDB) also publishes AfDB procurement notices. For consulting opportunities, monitoring the AfDB website and UNDB for Expressions of Interest is essential.
Bid Preparation Best Practices
Successful bidders invest significant effort in bid preparation. For goods and works ICB, critical success factors include: thorough review of the bidding documents (particularly instructions to bidders, evaluation criteria, and technical specifications), compliance with all documentary requirements (bid security, power of attorney, financial statements, experience certificates), competitive pricing that reflects actual costs plus reasonable margin, and timely submission with adequate margin for delays.
For consulting proposals, quality of the technical proposal is paramount. This means: a clear understanding of the assignment demonstrated in the methodology, a realistic and detailed work plan, well-qualified key personnel with verifiable experience on similar assignments, and evidence of relevant country or regional experience. The technical proposal should be concise, specific, and directly responsive to the Terms of Reference — generic or marketing-heavy proposals score poorly.
The Evaluation Process
AfDB procurement evaluations follow a structured process with Bank oversight. For goods and works, bids are opened publicly at the time and place stated in the bidding documents. The evaluation committee examines bids for responsiveness (compliance with mandatory requirements), corrects arithmetical errors, applies any applicable domestic preference, and ranks bidders by evaluated price. The evaluation report is submitted to the AfDB for no objection review before the contract can be awarded.
For consulting services under QCBS, the technical evaluation is conducted first using the published criteria and weightings. Technical scores are submitted to the AfDB for review. Only after receiving no objection on the technical evaluation are financial proposals opened. The combined technical and financial scores determine the ranking.
Common Mistakes to Avoid
Experienced AfDB procurement specialists consistently identify several common mistakes that lead to bid disqualification or low scores: submitting after the deadline (late bids are rejected regardless of content), failing to provide required bid security in the correct form and amount, not meeting minimum qualification requirements (experience, turnover, equipment), proposing key personnel who are not available or whose CVs are inflated, submitting generic technical proposals that do not address the specific Terms of Reference, pricing errors and inconsistencies between the bill of quantities and the bid price summary, failing to sign or authenticate the bid properly, and ignoring addenda or clarifications issued during the bidding period.
Sector Focus Areas
The AfDB lending programme focuses on five priority areas known as the High 5s: Light Up and Power Africa (energy), Feed Africa (agriculture), Industrialise Africa (industrial development), Integrate Africa (regional infrastructure), and Improve the Quality of Life for the People of Africa (health, education, water). Understanding these strategic priorities helps suppliers identify the sectors with the largest volume of AfDB-funded procurement and align their capabilities accordingly.
Infrastructure — including transport, energy, water, and ICT — consistently accounts for the largest share of AfDB-funded procurement. However, the Bank increasing focus on climate resilience, digital transformation, and human capital development is creating growing opportunities in consulting, technology, and social sector services.
