World Bank bidding documents for works, explained section by section

Procurement in World Bank investment projects follows the Procurement Regulations for IPF Borrowers, now in their seventh edition (September 2025). The edition that applies is set by the project's legal agreement and named in the Specific Procurement Notice, so a tender can follow an earlier one. International competitive procurement must use the Bank's SPDs; national competitive procurement may use the borrower's own documents if the Bank finds them acceptable (paragraph 5.24).

For a bidder, three rules stand out. Your rights and obligations are governed by the bidding document and the contract, not by the Regulations or the loan agreement (paragraph 2.1). Open international procurement allows at least 30 business days to prepare bids unless the Bank agrees otherwise (paragraph 5.36). And the Bank arranges publication of the Specific Procurement Notice on its website (paragraph 5.23).

Versions differ: one works SPD adds the Bank's disqualification mechanism for sexual exploitation and abuse and sexual harassment (SEA/SH) obligations on high-risk projects, Section III has texts for bidding with and without prequalification, and smaller contracts can use the Request for Bids for Small Works.

The Specific Procurement Notice is not part of the bidding document (ITB 6.2). The document itself, read with any addenda issued under ITB 8, is made up as follows.

Each BDS entry is keyed to the ITB clause it completes: BDS ITB 18.1 gives the bid validity date, BDS ITB 19.1 the security or declaration, BDS ITB 32.2 the rated criteria and weightings. The BDS complements, supplements or amends the ITB and prevails where they conflict, and an addendum under ITB 8 can change either. Extract these first, because each can disqualify you or change your price:

Each bid goes in two sealed envelopes inside an outer one (ITB 11 and 21). The technical part holds the technical letter of bid, the security or declaration, the signatory's authorisation, the qualification documents, the technical proposal, the SEA/SH declaration and the local labour method statement. The financial part holds the financial letter of bid, with the price and any discounts, and the priced bill of quantities. Then:

Section III contains all the criteria the employer may use; no others may be applied. Its pass/fail table states, for each requirement, whether a joint venture meets it with all members combined, with each member or with one member. The template's requirements:

Three rules catch contractors out. Amounts are stated in US dollars, at the rate on the last day of each calendar year for turnover and on the contract date for a single contract. Only your own firm counts: the Regulations exclude parent companies, subsidiaries, affiliates and subcontractors other than permitted specialised subcontractors (paragraph 6.27). And the document defines similarity, by size, complexity, method or technology. Check everyone in your bid against the Bank's list of debarred firms, then make a bid/no-bid decision before you price.

Section VII's environmental and social (ES) requirements, labelled ESHS (environmental, social, health and safety) in older editions, come from the project's commitments under the Bank's Environmental and Social Framework and its SEA/SH obligations: health and safety, environmental protection, hazardous materials, site security, labour conditions and more.

In the bid they become documents the evaluators read: the ES management strategies and implementation plans (ES-MSIP), the code of conduct for contractor's personnel, the SEA/SH declaration and Form CON-3 on past ES performance. They bind after award too: the template says the contractor may not mobilise to site until the Engineer consents that these measures are in place. The contract data may add an ES performance security, normally 1% to 3% of the accepted contract amount.

The September 2025 edition adds a local-labour rule. Unless the BDS says otherwise, you must allocate at least 30% of the total labour cost under the contract to local labour and submit a Local Labour Method Statement, set out by skill category in full-time equivalents, which becomes part of the contract (ITB 16.2 and the Section IV form). It implements paragraph 5.54 of the Regulations' seventh edition, and ITB 15 tells bidders to take it into account when stating their local and foreign currency requirements.

Section VIII incorporates, without printing them, the General Conditions of FIDIC's Conditions of Contract for Construction for Building and Engineering Works Designed by the Employer (the Red Book), second edition 2017, reprinted 2022 with amendments, and says the original must be obtained from FIDIC. Buy it: you cannot price the risk in a contract you have not read.

Section IX prevails over those conditions. Part A, the Contract Data, sets the parties, the time for completion, the defects notification period (365 days in the template), the performance and ES performance securities, the contractor's total liability and more. Part B, the Special Provisions, amends FIDIC's clauses; Part C covers fraud and corruption; Part D sets ES metrics for progress reports.

Two contract points reach back into the bid. The technical letter of bid asks you to propose three potential members of the Dispute Avoidance/Adjudication Board, with their CVs. And the performance security, a demand guarantee or a bond from an issuer the employer accepts (ITB 49), must be one your bank or surety will issue, in the Section X form or another form acceptable to the employer.

Before you seal the envelopes, check each point against the document. For the wider list of reasons bids fail, see why tenders are rejected.

Bidligence's GLOBAL procurement profile is written for development-bank and multi-country tenders, and the analysis is told to use it for them; 21 regional profiles cover national systems. GLOBAL expects bidding under development-bank standard documents, naming the World Bank SPD for works, with strict eligibility, security and form compliance and debarment lists, and counts the FIDIC 2017 books and the World Bank Environmental and Social Framework among its standards.

Bidligence reads a tender pack in order of authority, newest amendment first, then the notices, instructions and data sheet, forms and bills, conditions and specifications; drawings and reference standards come last and are capped in length, and scanned pages are transcribed before the analysis runs. The analysis records the procurement framework, evaluation method and weighted criteria, pass/fail eligibility, the mandatory documents, the returnable schedules in the tender's own numbering, key personnel, the security and validity, ESG and local-content requirements, risk flags and questions for clarification.

From there, on a paid plan, the Compliance Matrix generator lists each mandatory requirement, document and key criterion with your Vault evidence or the action needed, and the Mock Evaluator scores your draft against the tender's weighted criteria and lists pass/fail issues separately. The Submission Guard checks the mandatory items against your Evidence Vault. None of it replaces reading the BDS: it gives you a list to read it against.

These are the development-bank and multilateral sources Bidligence reads for its tender feed, which comes with saved searches on the Free plan:
