某大学投资兴建一综合实验楼,结构采用现浇框架一剪力墙结构体系,地上建筑为15层,地下为2层。通过公开招标,确定了某施工单位为中标单位,双方签定了施工承包合同。
该工程采用筏形基础,按流水施工方案组织施工。在第一段施工过程中,材料已送检,为了在雨期来临之前完成基础工程施工,施工单位负责人未经监理许可,在材料送检时,擅自施工。待筏基浇筑完毕后,发现水泥试验报告中某些检验项目质量不合格,如果返工重做,工期将拖延15天,经济损失达1.32万元。
某天凌晨两点左右,该综合实验楼发生一起6层悬臂式雨篷根部突然断裂的恶性质量事故,雨篷悬挂在墙面上,幸好未造成人员伤亡。该工程为6层砖混结构宿舍楼,建筑面积2784m2,经事故调查、原因分析,发现造成该质量事故的主要原因是施工队伍素质差,在施工时将受力钢筋位置放错,使悬臂结构受拉区无钢筋而产生脆性破坏。

如果该工程施工过程中实施了工程监理,监理单位对该起质量事故是否应承担责任,原因是什么
