某市一建筑工程公司承建了该市开发区某20层住宅楼，总建筑面积2600m2，建筑高度66.32m，全现浇钢筋混凝土剪力墙结构，地下为筏板基础。工程在外檐装修时采用的是可分段式整体提升脚手架，脚手架的全部安装升降作业，以工程分包的形式交给了该脚手架的设计单位进行。在进行降架作业时，突然两个机位的承重螺栓断裂，造成连续五个机位上的十条承重螺栓相继被剪切，楼南侧51m长的架体与支撑架脱离，自45m的高度坠落至地面，致使在架体上和地面上作业的20余名工人，除一人从架体上跳入室内幸免外，其余19人中有8人死亡，11人受伤。经调查，承重螺栓安装不合理，造成螺栓实际承受的载荷远远超过材料能够承受的载荷;脚手架整体超重，实际载荷是原设计载荷的2.7倍;施工现场管理混乱，施工设计方案与现场实际情况不符，施工队伍管理松驰。
问题：
