[案例一]
[背景]
某穿堤建筑物施工招标，A、B、C、D共4个投标人参加投标。招标投标及合同执行过程中发生了如下事件：
事件1．经资格预审委员会审核，本工程监理单位下属的具有独立法人资格的D投标人没能通过资格审查。A、B、C3个投标人购买了招标文件，并在规定的投标截止时间前递交了投标文件。
事件2：评标委员会评标报告对投标人的投标报价有如下评估。投标人的工程量清单“土方开挖(土质级别Ⅱ级，运距50m)”项目中，工程量2万m³与单价500元/m³的乘积与合价10万元不符。工程量无错误，故应进行修正。
事件3：招标人确定B投标人为中标人，按照《堤防和疏浚工程施工合同范本》签订了施工承包合同。合同约定合同价500万元，预付款为合同价的10%，保留金按当月工程进度款5%的比例扣留。施工期第1个月，经监理单位确认的月进度款为100万元。
事件4：根据地方政府美化城市的要求，设计单位修改了建筑设计。修改后的施工图纸未能按时提交，承包人据此提出了有关索赔要求。
