Joint Ventures or Solo Bids? The Math Behind Winning Large African Tenders

​The decision that happens before the technical proposal is even drafted

​Long before an engineering firm drafts a methodology or prices a Bill of Quantities, it has to answer a more consequential question: bid alone, or bid in partnership? On large African infrastructure and consulting assignments — roads, energy, water, rail, ports — this decision shapes eligibility, risk exposure, and often the outcome of the tender itself, before a single technical page is written.

​The evidence from actual African procurement outcomes over the past two years shows this is not a marginal consideration. It has determined who gets shortlisted, who gets disqualified, and — in at least one high-profile Kenyan case — who lost a half-billion-dollar concession entirely because a joint venture partner walked away.

​Why Development Finance Institutions Push Firms Toward Partnership

​Donor-funded procurement is structurally biased toward joint ventures for consulting assignments, and the bias is written into the rules, not left to chance. The African Development Bank's own guidance on consultancy procurement states that its Rules stipulate there should be at least one regional consulting firm — and, where possible, at least one regional or national firm in joint venture or association with a non-regional firm — on the shortlist a Borrower prepares for a Bank-financed assignment. That is a structural requirement, not a preference: an international firm bidding solo into many AfDB consulting assignments is competing on a shortlist explicitly designed to include a local or regional JV partner somewhere on it.

​Independent tender-strategy guidance drawing on World Bank, AfDB, and Islamic Development Bank experience echoes the same pattern from the demand side. Development-bank-financed tenders weight demonstrated technical capacity and directly relevant past project experience heavily — often more heavily than price — particularly under Quality and Cost-Based Selection (QCBS) for consulting services. The practical consequence for a firm without a multi-project track record in the development-finance space: a first bid into this segment is far more likely to succeed as part of a joint venture with an established development-sector firm, or as a subconsultant under a larger lead firm, than as an unproven sole bidder going head-to-head against firms with a twenty-project record in the sector.

​For turnkey and EPC-type contracts specifically, the AfDB notes that consulting firms and suppliers may be associated in a joint venture, with the resulting contract structured as a lump-sum remuneration arrangement for the specified duration of services — a format built around the assumption that design and delivery capability may sit in different firms brought together for the bid.

​A Verified Case for the Upside: Olkaria IV and the Turnkey Consortium Model

​One of the clearest, well-documented examples of a joint venture converting into a major African infrastructure win is Kenya's Olkaria IV geothermal power plant. In 2011, Kenya signed a deal for the 280 MW plant, an extension of the existing Olkaria I and II stations, and the Kenya Electricity Generating Company (KenGen) awarded the project as a full turnkey contract to a consortium of Hyundai Engineering & Construction and Japan's Toyota Tsusho Corporation. The plant, completed around 2015 at an investment value of roughly $1 billion, was funded through a mix of the Kenyan government, the World Bank, and other European and Asian development institutions.

​The structure is instructive: neither firm bid solo. Hyundai brought heavy engineering and construction execution capacity; Toyota Tsusho brought trading, financing, and project structuring capability. Together they met a bar — full turnkey delivery on a geothermal plant of that scale, financed through a multi-institution donor stack — that neither was contracted to deliver alone.

​A Verified Case for the Downside: What Happens When a JV Partner Walks

​The clearest recent illustration of joint venture risk in African infrastructure is the collapse of the Usahihi Nairobi–Mombasa Expressway PPP, a proposed 419-kilometre, roughly Sh468 billion ($3.6 billion-plus) project. Everstrong Capital, the lead proponent, had submitted a privately initiated proposal built around a consortium that depended on Portuguese contractor Mota-Engil for both equity financing and specialist construction expertise. When Mota-Engil exited the consortium, it left the bid without what reporting on the case described as its cornerstone partner.

​Kenya's Public Private Partnerships Committee rejected the proposal for failing to meet statutory thresholds on financial capacity, technical feasibility, and overall viability under the PPP Act. Everstrong's appeal to the PPP tribunal was dismissed in full. Underlying the commercial collapse was a further complication: Mota-Engil is partly owned by China Communications Construction Company, the parent of China Road and Bridge Corporation — and American lenders reportedly declined to finance the highway while Chinese ownership remained anywhere in the consortium's capital structure. The project's own government-preferred alternative — upgrading the existing highway rather than proceeding with the JV-led greenfield proposal — proceeded instead.

​The lesson generalises well beyond this one deal: a joint venture bid is only as strong as its weakest structural link, and that link can be commercial (a partner's exit), financial (a lender's exposure limits), or geopolitical (a state-linked shareholder tripping a foreign investment restriction) — often more than one at once.

​Scale and Sovereign Caps: The Rironi–Mau Summit Precedent

​A second, more recent Kenyan case shows how joint venture structuring interacts directly with sovereign and regulatory limits rather than just commercial fit. The Sh200 billion Rironi–Mau Summit Expressway, a 175-kilometre four-lane upgrade on the Nairobi–Nakuru corridor, was originally proposed as a single full-corridor concession led by a joint venture between China Road and Bridge Corporation (CRBC) and Kenya's National Social Security Fund (NSSF), alongside a competing proposal from Shandong Hi-Speed Road and Bridge International (SDRBI).

​Both consortiums separately concluded they could not proceed with the full-corridor scope, citing a $1 billion outbound-investment cap on Chinese state-owned enterprises that would have triggered a lengthy internal review inside China. Kenya's PPP Committee responded in November 2025 by splitting the project into two sections rather than losing both bidders: CRBC–NSSF took the 139-kilometre Nairobi–Naivasha–Gilgil and A8 South segments, while SDRBI took the remaining 94-kilometre Gilgil–Mau Summit stretch, each within the investment threshold on its own.

​For engineering and consulting firms structuring their own joint ventures on large African concessions, the takeaway is concrete: a JV's viability isn't fixed only by the partners' combined technical and financial capacity — it is also bounded by capital caps, home-country outbound investment rules, and financing-source restrictions that can force a renegotiation of scope even after a consortium has been provisionally selected.

​Nigeria: Where the Joint Venture is the Entry Ticket, Not Just an Advantage

​In sectors governed by local content law, a joint venture is often not a strategic option at all — it is close to the only route to market. Nigeria's Oil and Gas Industry Content Development Act of 2010 requires substantial local participation in procurement, engineering, and fabrication activity in the sector, and indigenous companies must hold at least 51% ownership in certain oilfield services companies under the Act.

​A documented example of this structure delivering a real contract is the joint venture between Samsung Heavy Industries Nigeria (SHIN) and LADOL, the privately owned free-trade zone at the entrance to Lagos harbour, which formed the JV known as SHI-MCI. SHIN tendered in 2010 and, in 2013, was awarded a contract by Total Upstream Nigeria for engineering, procurement, and construction work on a floating production facility — work executed through the local joint venture structure required to satisfy Nigerian content rules. Engineering firms entering Nigeria's oil, gas, and related infrastructure sectors without a qualifying local partner are, in practice, not eligible to bid on a large share of the available scope, regardless of technical strength.

​Building the Decision Framework

​Pulled together, these cases point to a working framework for engineering and consultancy firms deciding how to structure a bid into African infrastructure and consulting markets:

​Bid solo when:

• ​Your firm already holds directly comparable, verifiable past-performance references for the specific funder and sector (a real advantage under QCBS and similar quality-weighted scoring)
• ​The assignment does not carry a statutory or policy requirement for local or regional participation
• ​You can meet the financial capacity and bid/performance security thresholds unaided
• ​Sole responsibility is preferable to shared liability under the contract's risk allocation

​Bid as part of a joint venture when:

• ​The funder's own rules push toward it — as with AfDB's shortlist requirement favouring at least one regional or national firm, or Nigeria's local content thresholds
• ​You lack a track record with this specific funder or in this specific country, and a partner with that track record materially strengthens the technical score
• ​The assignment is turnkey or EPC in nature and no single firm in your organisation covers both design and construction delivery
• ​Local content, indigenous ownership, or in-country registration rules make a qualifying local partner a precondition to bid at all

​Before signing any JV agreement, stress-test it against:

• ​What happens contractually and financially if the lead or cornerstone partner exits mid-process, as happened on the Usahihi Expressway
• ​Whether any partner's ownership structure could trigger a lender, sovereign, or foreign-investment restriction once the deal reaches financial close, as on the Rironi–Mau Summit project
• ​Whether the JV's combined scope will still be viable if regulatory caps force a later reduction in scale
• ​Who holds decision rights on procurement, technical sign-off, and change management once work begins — not just at bid stage

​The Underlying Principle

​Across AfDB shortlisting rules, Nigeria's local content law, and Kenya's two recent large PPP road cases, the pattern is consistent: development finance institutions and national procurement frameworks in Africa are not neutral on the solo-versus-JV question. They actively steer bidders toward partnership on exactly the assignments — large, technically complex, capital-intensive — where the stakes of getting the structure wrong are highest. A joint venture bought purely for eligibility, without genuine due diligence on a partner's financial durability and regulatory exposure, is not a risk mitigant. As the Usahihi Expressway shows, it can just as easily become the single point of failure that sinks an otherwise viable bid.
