2.18 All prospective bidders shall be provided the same information, and shall be assured of equal opportunities to obtain additional information on a timely basis. Borrowers shall provide reasonable access to project sites for visits by prospective bidders. For works or complex supply contracts, particularly for those requiring refurbishing existing works or equipment, a pre-bid conference may be arranged whereby potential bidders may meet with Borrower representatives to seek clarifications (in person or online). Minutes of the conference shall be provided to all prospective bidders with a copy to the Bank (in hard copy or sent electronically). All modifications of bidding documents, including with regard to additional information, clarifications, and corrections of errors, shall be sent to each recipient of the original bidding documents and all bidders on record in sufficient time before the deadline for receipt of bids to enable bidders to take appropriate actions. Any modification to the bidding documents shall be introduced in the form of an addendum. If necessary, the deadline shall be extended. The Bank shall receive a copy (in hard copy or sent electronically) and be consulted for issuing a no objection when the contract is subject to prior review.
