Multilateral development bank tenders explained (World Bank, ADB, EIB, IsDB)

Development banks — the World Bank, Asian Development Bank, African Development Bank, EIB, Islamic Development Bank, EBRD and others — finance thousands of projects a year in infrastructure, health, energy and social development. For suppliers and consultants, that’s a huge, structured stream of opportunities. Here’s how it works.

Who is the buyer?

A key point: on a bank-financed project, the borrower (a government agency) is the buyer and signs the contract — the bank provides the money and sets the procurement rules and oversight. So you bid to the implementing agency, but you must follow the bank’s procurement framework and the tender’s standard bidding documents.

The three procurement categories

• Goods — equipment, vehicles, IT, medical supplies. Usually lowest-evaluated compliant bid.
• Works — construction and civil works. Bid on price against a bill of quantities, subject to qualification.
• Consulting services — studies, design, supervision, technical assistance. Selected on quality, or a quality/cost mix.

How consultants are selected

Consulting assignments typically start with an Expression of Interest (EOI) to build a shortlist, then a Request for Proposals. Common methods:

• QCBS — Quality- and Cost-Based Selection: technical and financial scores are weighted (often 80/20).
• QBS — Quality-Based Selection: chosen on technical merit, price negotiated after.
• LCS / FBS — Least-Cost or Fixed-Budget Selection for standard or budget-capped work.

Where notices are published

Development banks publish procurement notices for their financed projects, and these often also appear on the borrower’s national e-procurement portal. It pays to monitor the banks whose regions and sectors match your work, and to set alerts so new notices reach you early.

Getting eligible

• Register on the relevant bank’s consultant/vendor roster and keep your profile current.
• Prepare a strong, project-specific EOI — banks shortlist on relevant experience, not general size.
• Check country and nationality eligibility for the specific financing.
• Stay off debarment/sanctions lists — banks cross-check every award.

MDB tenders reward specialists: a focused firm with directly-relevant references usually beats a bigger, more generic competitor on the technical score that decides most of these awards.
