某工程,建设单位委托监理单位承担施工阶段监理任务。在施工过程中,发生如下事件:

事件1:专此监理工程师检查机构手里钢筋电焊接头时,发现存在质量问题(表3-8),随即向施工单位签发了《监理工程师通知单》要求整改。施工单位提出,是否整改应视常规批量抽检结果而定。在专业监理工程师见证下,施工单位选择有质量问题的钢筋电焊接头作为送检样品,经施工单位技术负责人封样后,由专业监理工程师送往预先确定的实验室,经检测,结果合格。于是,总监理工程师同意施工单位不再对该批电得接头进行整改。在随后的月度工程款支付申请时,施工单位将该检测费用列入工程进度款中要求一并支付。

事件2:专业监理工程师在检查混凝土试块强度报告时,发现下部结构有一个检验批内的混凝土试块强度不合格,经法定检测单位对相应部位实体进行测定,强度未达到设计要求。经设计单位验算,实体强度不能满足结构安全的要求。

事件3:对于事件2,相关单位提出了加固处理方案并得到参建各方的确认。施工单位为赶工期,采用了未经项目监理机构审批的下部结构加固、上部结构同时施工的方案进行施工。总监理工程师发现后及时签发了《工程暂停令》,施工单位未执行总监理工程师的指令继续施工,造成上部结构例塌,导致现场施工人员1死2伤的安全事故。

按《建设工程监理规范》的规定,写出项目监理机构对事件2的处理程序。
