某工程项目，建设单位与施工单位签订了施工合同。合同工期为9个月，合同总价为840万元。项目监理机构批准的施工进度计划如图5-1所示(时间单位：月)，各项工作均按照最早时间安排且匀速施工，施工单位的部分报价见表5-1。施工合同中约定：预付款为合同总价的20%，当工程款支付达到合同价的50%时开始扣预付款，3个月内平均扣回；质量保证金为合同价的5%，从第1个月开始，按每月进度款的10%扣留，扣完为止。
工程于2005年3月1日开工，施工中发生了如下事件：
事件1：建设单位接到政府安全管理部门将于6月份进行现场工程安全施工大检查的通知后，要求施工单位结合现场安全状况进行自查，对存在的问题进行整改。施工单位进行了自查整改，并向项目监理机构递交了整改报告，同时要求建设单位支付为迎接检查进行整改所发生的费用。
事件2：现场浇筑的混凝土楼板出现了多道裂缝，经有资质的检测单位检测分析，认定是商品混凝土的质量问题。对此，施工单位提出，因混凝土厂家是建设单位推荐的，故建设单位负有推荐的责任，应分担检测的费用。
事件3：K工作施工中，施工单位以按设计文件建议的施工工艺难以施工为由，向建设单位书面提出了工程变更的请求。
