【简答题】
背景： 某工程的施工合同工期为16，项目监理机构批准的施工进度计划如图所示(时间单位：)。各工作均按匀速施工。施工单位的报价单(部分)见下表。 工程施工到第4时进行进度检查，发生如下事件： 事件1：A工作已经完成，但由于设计图纸局部修改，实际完成的工程量为840立方米，工作持续时间未变。 事件2：B工作施工时，遇到异常恶劣的气候，造成施工单位的施工机械损坏和施工人员窝工，损失1万元，实际只完成估算工程量的25%。 事件3：C工作为检验检测配合工作，只完成了估算工程量的20%，施工单位实际发生检验检测配合工作费用5000元。 事件4：施工中发现地下文物，导致D工作尚未开始，造成施工单位自有设备闲置4个台班，台班单价为300元/台班、折旧费为100元/台班。施工单位进行文物现场保护的费用为1200元。 问题： 1、根据第4末的检查结果，逐项分析B、C、D三项工作的实际进度对工期的影响，并说明理由。 2、若施工单位在第4末就B、C、D出现的进度偏差提出工程延期的要求，项目监理机构应批准工程延期多长时间?为什么? 3、施工单位是否可以就事件2、4提出费用索赔?为什么?可以获得的索赔费用是多少? 4、事件3中C工作发生的费用如何结算? 5、前4施工单位可以得到的结算款为多少
