题目内容

某工程项目承包合同采用可调价单价合同。根据合同约定，总工期为9个月，工程预付款为原合同总价的10%，主要材料、构件所占比重为65%；若子项工程的实际工程量超过估计工程量 10%时可调价，调价系数为0.9。各工作的估计丁程量及承包商提出的工程量清单计价表如表 5-5所示。
经批准的工程施工进度计划如图5-2所示。浚项目的各项工作均按最早开始时间安排，且各工作每月完成的工程量相等。各项工作每月的实际工程量如表5-6所示。
该工程在施工过程中发生如下事件： (1)A工作遇到了地质报告中没有探明的地下障碍物，地下障碍物处理没有延长A工作的时间，但是增加了施工成本1万元。 (2)承包商为了提高基础工程的质量，提高B工作的混凝土强度等级，导致增加施工成本1.6万元。 (3)F工作施工1个月后，因业主要求修改设计，致使工作F停工待图2个月。针对以上情况，承包商提出的索赔申请如表5-7所示。表5-7 承包商提出的索赔申请有关数据表
