The approved selection methods under the World Bank Regulations differ depending on whether the procurement is for (i) goods, works, or other nonconsulting services or (ii) consulting services.

Table 1 below provides an overview of the approved selection methods, particular types of approved selection arrangements, and market-approach options available for the procurement of goods, works, and nonconsulting services in IPF operations.

Table 2 below provides an overview of the approved selection methods, particular types of approved selection arrangements, and market approach options available for the selection of Consulting Services in IPF operations.

Prequalification may be requested before the bid-submission deadline. It must be published in at least two national and international newspapers, on the relevant ministry's website, and on any website available to the procuring entity. Prequalified bidder may not join other prequalified bidders in making their proposals. The procuring entity will determine whether the bidder meets World Bank requirements for operational expertise, technical expertise, and financial capability.

The World Bank will debar contractors for five types of conduct qualify for exclusion: corrupt, fraudulent, collusive, coercive, and obstructive practices. Debarment can be temporary or permanent. The Bank has two alternative options. It may impose confidential non-debarment, which lasts for a specific time while the contractor satisfies the conditions for avoiding debarment. The Bank may also impose debarment with conditional release, which sets a minimum timeline on exclusion, with the option of unlisting the contractor once requirements are met.

A firm shall be considered to have a conflict of interest if the firm:

1. Is providing goods, works, or nonconsulting services resulting from, or directly related to, consulting services that it provided for the preparation or implementation of a project, or where such services were provided by an affiliate that directly or indirectly controls, is controlled by, or is under common control with that firm. This provision does not apply to the various firms which together are performing the contractor's obligations under a turnkey or design and built contract;
2. Including its personnel, has a close business or family relationship with a professional staff of the borrower, or of the project implementing agency, or of a recipient of a part of the Bank's financing, or any other party representing or acting on behalf of the borrower who:
1. Is directly or indirectly involved in the preparation of the procurement documents or contract specifications, and/or the evaluation process of such contract;
2. Would be involved in the execution or supervision of such contract, unless the conflict stemming from such relationship has been resolved in a manner acceptable to the Bank throughout the procurement process and execution of the contract; or
3. Does not comply with any other conflict of interest situation as specified in the Bank's standard procurement documents.

A firm shall not submit more than one bid/proposal, either individually or as a joint venture partner, except for permitted alternative bids or proposals. Submitting or participating in more than one bid/proposal results in the disqualification of all bids/proposals in which the firm is involved. this does not limit the inclusion of a firm as a subcontractor in more than one bid/proposal. For certain types of procurement, however, the bidder's participation as a subcontractor in another bid/proposal may be permitted as allowed by the Bank's applicable standard procurement documents.

The Regulations do not address this.

The Regulations do not specify limitations.

For international competitive procurements, all procurement documents shall be in English, French, or Spanish, as the borrower chooses. The borrower may also issue translated versions of these documents in another language, which should be the national language. The national language is either:

1. The national language of the borrower; or
2. The language used nationwide in the borrower's country for commercial transactions, and the Bank is satisfied that this is the language used.

The borrower shall take full responsibility for correct document translation into the national language. In case of any discrepancy, the English, French, or Spanish text prevails. If procurement documents are issued in two languages, potential bidders, proposers, and consultants may submit their applications, bids, or proposals in either of those two languages.

For international competitive procurement that is subject to prior review, the borrower has the responsibility to furnish to the Bank an accurate translation of the (1) evaluation report for prequalification, shortlisting, bid, or proposal; (2) draft contract; and (3) conformed copy of the contract. These translations must be in English, French, or Spanish—whichever is specified in the request for bids or request for proposals documents. The borrower shall also furnish the Bank an accurate translation of any subsequent contract modifications.

For national procurement, procurement documents may be in the national language. When documents are in the national language, the Bank may require the borrower to provide, for its review, an accurate translation in English, French, or Spanish.

The winning contract shall always be written in the language in which the bid/proposal was submitted. The contract shall not be signed in more than one language.
