投标履约保函是什么意思呀英文？
投标履约保函（Bid and Performance Bond）通常被称为 "Bid Bond" 和 "Performance Bond"。那么，让我们详细了解一下它们的含义和用途：
投标保函 (Bid Bond)
投标保函是一种融资担保，通常在招标过程中使用。投标人作为保函受益人，由担保人（如保险公司）签发。投标保函保证，如果投标人在招标中获胜，他们将按照招标要求签订合同并提供履约保函。投标保函的目的是确保投标人有能力完成合同，并防止他们玩忽沓责或随意撤回投标。
投标保函的金额通常为合同价值的 5%-10%，具体金额由招标方确定。对于大型项目，投标保函的金额可能会更高。投标保函在中标者确定后通常会失效或退回。
履约保函 (Performance Bond)
履约保函是一种更全面的融资担保，用于确保合同的履约。履约保函由中标者/承包商作为保函受益人，由担保人（如银行或保险公司）签发。履约保函保证，承包商将履行合同中的所有义务，并确保项目按时、按预算和按指定标准完成。
履约保函的金额通常为合同价值的 5%-10%。履约保函在项目完工并验收后通常会失效或退回。然而，在某些情况下，履约保函的期限可能会延长，直到项目的缺陷责任期结束。
