Laochan

以下是2011年版世行《采购指南》中关于投标保证金的规定：

2.14 借款人可以选择是否要求投标人提交投标保证金。如果要求提交投标保证金，投标保
证金应该按照招标文件中规定的金额和格式提交。投标保证金应在投标有效期期满后的一段
时间（通常为4 周）内保持有效，以使借款人在需要没收保证金时有充足的时间。在与中标的
投标人签订合同之后，借款人应及时向未中标的投标人退还投标保证金。借款人也可以不要求
投标人提交投标保证金，而是要求投标人递交一项声明，声明如果投标人在投标有效期内撤回
或修改其投标书，或者在被授予合同之后未能与借款人签订合同，或不能在招标文件规定的截
止日期前向借款人提交履约保证金，则该投标人在招标文件规定的一段时间内没有资格参与该
招标人实施招标的任何合同的投标。

2.14 Borrowers have the option of requiring a bid security. When used, the bid security shall be in the amount and form specified in the bidding documents and shall remain valid for a period (generally 4 (four) weeks beyond the validity period for the bids) sufficient to provide reasonable time for the Borrower to act if the security is to be called. Bid securities shall be released to unsuccessful bidders once the contract has been signed with the winning bidder. In place of a bid security, the Borrower may require bidders to sign a declaration accepting that if they withdraw or modify their bids during the period of validity or they are awarded the contract and they fail to sign the contract or to submit a performance security before the deadline defined in the bidding documents, the bidder will be suspended for the period of time specified in the bidding documents from being eligible to bid for any contract with the entity that invited bids.
